Good video! This is personally why I run motul xcess 5w40 as it doesn’t break down viscosity as fast. Also from my readings the x clean was designed more for new euro emissions over the xcess which has better protection. I also used to have a sponsorship from Puröl which claims to have good amounts of zinc
Do you have a playlist for the oil test? I would love to see everything that you have done and/or are doing! It would also be nice to know what filter you use. Can you test Amsoil Signature Series!? I am also surprised you aren't doing the same thing for your diffs. Maybe also a test on gear lube. Amsoil also makes a 100% for diffs that work pretty well. Love the video tho.
Agreed, ive seen some pils come out pretty water lookong after about 3K miles. Oil is one of the biggest things with these cars. They get HOT and will break down oil quickly
Hey bro! Love watching your videos, I just got my first STI in December, I’m learning lots from you. But I have a new respect for you after this video, I also have chickens lol 👍
10:20 "Molybdenum" is actually an anti wear additive used in oils.. sometimes referred to as a friction modifier, "Boron" is also used as an anti wear additive. Oils like Motul and Amsoil are labeled as 100% synthetic base oil seem to have better lubrication properties and don't need higher amounts of Molybdenum but additive packages will vary across all oil brands. But you will surely find these 2 elements in brand new oils before they're ever ran inside an engine.
Being that Motul XClean is a high detergent lower Kinetic Viscosity oil I would attribute the slightly higher Elements as a result of the higher flow rates “washing” deposits from older oil intervals. I would be more excited about the drastic drops in the higher friction areas of the motor remember the valve spring cycle more frequently than the crank shaft, the piston rings are the sacrificial element and they were less sacrificed.
Must have liberal arts education, you know the kind of people who think Shakespeare and pretty pictures will save the world. Seeing you have the time to critique grammar on a platform where most replies contain hearts and smiley faces.
I see your Motul results. I understand Motul did a great job working its way into the Subaru enthusiasts shops. Most feel the Motul is best for the Subaru. Wonder how many Motul guys have tried the proper grade Amsoil in their Subarus.
Amsoil SS and redline 5w-30 has great used oil analysis results on my sti. My car HATED Motul xcess 5w-40. Immediate dam drop which puzzled my tuner. Second I dumped the oil dam went back to 1.
Bro, of all ppl on youtube you are the true Subaru whisperer! Hypothetically, what would you run in a VA WRX with an intake and a tune? I have been using Pennzoil Ultra Premium 5w-30 since day one 3k-4k oil intervals the car runs happy. No visual fuel dilution present when used oil is drained.
I wouldn’t worry too much about those results. I have a WRX with 165,000 and it still runs smooth (and I still drive it hard occasionally). I would be afraid to see the results on it though since it has so many miles😂 I change every 5,000 with rotella 5w-40.
Not overly worries but interesting to see some of the values increase from the last test, and as long as they're running smooth thats all that matters 🔥😁
@@commentmancommentman1658bought an 04 wrx, ej25 swapped and catless dp and he was running rotella t6, just did an oil change yesterday with motul 5w-30 x-clean and imo the car ran wayy smoother but it's only been a day so I'll see how it turns out
@@commentmancommentman1658 Not true about the cats being damaged using that oil. I have an 08 STI with 130,000 miles. Been running Rotella T6 since 20,000 miles and I've had zero issues with my catalytic converter.
Most of the top synthetic brands are pretty decent, but Amsoil and Pennzoil Ultra Platinum are the best and have seen test after test of those coming #1 #2. They even have Ultra Platinum that is especially formulated for SRTs, and is what I run in my Challenger. What's good for a big V8, isn't always going to be the same as with a high-revving Japanese engine and may do better with Castro or one of the others
A year late on this one but whatever. I've gone pretty deep down the rabbit hole on oil research, coming to the same conclusion. If you just want a quality full synthetic motor oil, most of the big brands are great and virtually indistinguishable from one another (Mobil 1, Castrol, Valvoline, Motul, Royal Purple, Penzoil, etc) at a functional level. They have comparable additive packages, impurity levels, similar breakdown, resistance to heat, viscosity under designed temperatures, and so on and so forth -regardless of what the labels say. You're really just paying for your brand loyalty and what colors you've got on the box. However if you want to go all the way on oil and get the best possible,you want Amsoil Signature Series full synthetic as your #1 choice, with Penzoil *Ultra* Platinum full synthetic at a close second. I went with the Penzoil Ultra Platinum since you can get it five quarts for $33 from Walmart most of the time, where Amsoil's offering is quite literally $18 per quart at time of writing. Being able to change the oil every 3000 will make for a happier engine than much more expensive oil every 5k.
👍🏻Oils have number ratings for a reason. So it doesn't matter if they use Penzoil ultra platinum in the SRT V8s. They run higher numbered oils, than a small Japanese V6 or I4.
I’m in Maine and have just modified my 2020 STI from stock to stage 3+ and bought from my tuner The 8100 but he recommended 5-40. We have the harsh some sub zero morning, so I’m really excited to see what your results will be on that!
That's why the chickens are loud because you're talking about oil. They, on the other hand, think that they are talking about frying oil and have become frightened that it is not already time to fry them. 😂😂
I’ve got a 19 STi, bought new and I use Schaeffer’s Supreme 9000 5w-40. I’ve sent a few samples over to Black Stone Labs and all have come back exceptionally well with them suggesting an 8,000mi interval. I’ve only went as far as 6,000 for testing purposes but yet change my oil regularly at 3,000mi. Not sure how much the oil filter attributes to the testing but I use the Mazda oil filter. As well, from what I have seen with the Motul 8100 line.... I’ve seen people say the 8100 X-Clean 5w-30 is best used in n the FA20 and the Motul 8100 X-Cess 5w-40 be used in the EJ25. Maybe something to look into.
Have both oils on the list to test and I have been using tbr Prova pil filters. Have had good results from them thus far. I have dhacers on my list as well and have heard and seen great results from their oil!
Mazda rx8 oil filters are identical to the old full size JDM STI filters used, I use them also. OEM subaru filters in america are junk theyre made by fram.
We should also consider that the more miles the car has the engine will brake down the oil differently. But I would like to get mine check on my next oil change
Glad you got the 30! Some dealers have to follow manufacturers policy for oil changes but at least they got you the right grade this time around for what you wanted 🙏
I always found Castrol and shell were best for my STi. I tried motul, liquimolly, mobile 1, a few other big name brands but the Castrol was always my #2 choice to shell Rotella, buy you can only run Rotella catless.
Which Rotella is recommended, got an 04 wrx a few months back, he said he used Rotella t6, car is catless, did an oil change yesterday with motul x clean 5w30 and imo the car runs better than before, a lot easier to get the car rolling and sounds a bit quieter but it's only been a day so I'll do some more driving to see if it keeps running good
@@chrisguzman7926 yeah Rotella T6 heavy duty diesel oil. Diesel oil has much more detergent elements in it like zinc, so it will plug up a cat but is really good in gas engines without the cat. Lots of motorcycle guys run it too. Way higher sheer temp, you'll notice your oil will come out amber instead of black when you change it.
@@Smeedia I hope you find the best brand/results you're looking for your Subie, I ran Motul excess 5-40 when I had my Stink Eye sti because it helped with less oil blowby at the pcv while having a Cusco catch can installed for peace of mind.
I hate to be a negative Nancy but that year STI is notorious for crank bearing failure. Mine developed a rod knock at 27k miles and I have a few friends that had the same issue with 15-17 STIs. Well if it does happen think of the all the new content you will have for the channel 😀.
Smeedia Meh as long as your expecting it. I thought I’d be one of the lucky ones because I had every supporting mod money could buy along with changing my oil every 2k miles. It really seems to have to do with luck when it comes to crank bearings and a good tune to avoid ringland failure IMO. Hopefully your one of the lucky ones. I recommend if you do go and build your motor try to scavenge up enough money to do the heads as well. I did just some mild bc272 cams, gsc valve train, and some pocket porting and it makes a huge difference up top. Best of luck and keep up the great content!
I was talking to my tuner about this also and it all seems to be luck of the draw with the 257s. When the motor does let go, gling to buy a IAG block and machine and build the heads valves, springs and cams essentially. When the car qas on the dyno we pretty much maxed the OE Cams out
So just to let you know I have post in a few the Subaru groups about my oil reviews. Thus far the Subaru oil and Amazon basics did the best in terms of wear protection and all that. The block in my WRX did start eating some of the motul oil and right now I'm running amsoil so I'll let you know how that one goes in a couple thousand miles.
@@Smeedia blackstone of course!! trying to keep a good control over certain aspects of this experiment. as soon as im out of fb jail, ill repost it to the group
Oil companies gotta love you 😍 , given how frequently you change oil! Oil life and contamination also relies on the quality of filter in addition to oil temperature, fuel type, A/F ratio, engine internal health and driving style ( 🔥 or 🐇) as you explained. Well done. Are you using the OEM filter or the more expensive STI filter; it's $$$$ at about 5 times the regular OEM. Curious are you going to test Subaru OEM oil? It is a full synthetic. Last but not least oil cooler addition might also help out too; cheaper than a new short block.
Ive got the perrin oil cooler that I still need to custom fit on the STI Because it won't fit with thr FMIC and I want to test both thr Subaru OEM and Motul Subaru OEM Oil that they made for the S209 🔥😁 as for filter I use the prove filters 🔥
My red flag is for this oil is 1/3 less miles, more wear indicators, they did not recommend extending service, while they suggested easily increasing change interval by 50% of the Castrol. If I want to be kind to motul, it was the 'clean' version, and maybe it cleaned stuff ... but nah :) My desire is to test mobil 1 extended performance high mileage. The fuel in oil is usually from excessive idling, short trips, many cold starts. If you get an hour highway drive a time or few a week will burn off the fuel contaminants. Guess this is sidelined with all the engines getting pulled in your garage :p
Also could be attributed to the fact that the car went on the dyno before that oil was sent out, don't remember if I mentioned that in this video or not😅 hopefully can start this back up soon with the 05 STI
@@Smeedia Awesome! I'm following the series too see what kind of results you get. Also, what is your opinion on weights? My local performance shop is also home of the famous "GetADomTune" and he recommends 5w40 which is what I've always done.
5W/40 is what I would suggest. Its a little more viscous so in theory it helps lubricate the bearings on the crank a little better for a little longer 🔥 and Dom is super knowledgeable have talked to him several times
Interested to see this i run amsoil full synthetic 5w-30. Keep up the good content. I made this comment on a your wing video. But would you say the apr gtc 300 would look better with or without removing my oem trunk lip?
can you tell me what the real use of this test? and but the way i saw a lot of different oil tests no one give you the truth but the one with pressure test on the rotor i think give you an indication at lest. one test motul is the best, another test shell is the best, another test castrol is the best just use the one that have the specificacion for your car and that'it.
I'd be scared to test my oil haha. Been running straight e85 for 2.5 years with 305whp on a ej205 (stock bottom end). I'm sure there wouldn't be great results lol, but its running flawless though.
I love your videos!! I’ve been reading all this comments, I already need an oil change, I own a stock 2015 Sti Limited and previously I used Motul X-Cess gen 2 5W-40. I need your advice, should I keep using the same one or should I change?
Thank you! And i normally run 5w/40 but some of the samples that ill be testing will be 5w/30 in theory the more viscious 40 should provide better lubrication between the crank and bearings
@@tian2339 ran it when i was living in Connecticut even in sometimes under 10 degree weather for years still using it now that im living in Texas where its 90+ alot u will be fine 100% i only use motul xcess 5w40
X cess 5w40 built 07 sti my fp green and motor loves the oil also not much piston slap on cold starts once it gets to 130f the forged internals a quiet 👌
Man I have a doubt. I have a conventional aspirated engine V6 car. In that case, would Motul oil be better than Castrol Edge? I mean, is Castrol better for turbo engines, and Motul for aspirated engines?
This video series is a good idea, but I'd say it's hard to use the STI as the "control" unless you left the car as is for every test. You've added a million parts in recent months lol
The only thing that should really have an effect on oil life is the ethanol and new tune on the car outside of that there shouldn't be much that effects it. And from what I found increased levels of it tend to come from the rings. But It could also be an additive
@@Smeedia more power = more strain and wear on the engine. You should definitely try to send the oil off with the same amount of miles or hours driven on every sample. Parts changed, fuel changed, tune changed, and miles between oil changes/samples inconsistent. Hard to draw any conclusive data from that.
Hey. I have a 16 wrx. Copper has been trending up the last 3 oil changes. I’ve only monitored it for 3 since it’s been tuned for flex fuel. Went from 17 to 42 to 61. About 3k miles oci. Other wear metals normal. No lead. No tin. Iron in the 10-20 range and actually trended down last oci. What could be the source of copper? No new oil cooler. Thanks!
Next time pay the extra 10 bucks for a TBN. That’s the most important part of this test and you skimped out on it. Put a couple of filter Mags on your oil filter and re-test. Metals will be reduced.
I use to do it for free at my old job, we had a TPN Tester and I could pull results for free. Just never added them in because test results were slow to come through.
Save your money guys, run Wal-Mart 5w30 full sin., and oil filter 👍 after 15k no issues, and l have a heavy foot, my STI is 2016 😉 l change oil & filter every 3k
Penny wise and a pound foolish! You shouldn’t have problems after only 15k miles, but if you want your motor to last I wouldn’t go with the “cheap” oil.
used motul efe 5w30 on my 2018 sti had 20k miles when i changed, i kid you not my oil was pitch black within 1.5k miles. i do drive the car a bit hard only sometimes tho never really go past 4k unless highway merging. gonna try amsoil signature next
i know this is an old ass comment but i wanted to pitch in and say that if your oil looks like new or anything close to new when you drain it for your normal interval oil changes, it's not a good oil. oil color doesn't mean everything, but if it's coming back completely clean, it's not doing its job. it's supposed to absorb contaminants so it can transfer it into the oil filter.
So i been using oem subaru oil for awhile 2020 sti about 22k on her. No aos yet or anything. Only intake and catback with just a cobb ots tune (for now) . So i tried the 5w30xclean this time around and noticed that at about 2k ive already went through like a qt which has me kinda worried. So im thinking ill just switch back to the oem until i can find another brand to try. I havnt sent a sample out yet because i ended up topping her off with some shell oil or mobil 1 until i change it again. Anyways going to grab an aos asap and just wonderin what your thoughts are like maybe my car just doesnt like that oil? Lol. I live in new england and its just starting to get really cold . I got a 30k service comin up soon thats covered so ima have em check it out than but obv warrentywise they could give me issues. Anyways just curious on your thoughts i know you said the report wasnt as good as you expected on that one. Any insight would be much appreciated. Thanks man
don't run energy conserving oil in a Subaru. 8100 xpower or v300, Fuchs titan race pro s, or get castrol edge supercar. you want oil with a higher zinc additive as we run bucket shims and need good oil film strength.
Well Subaru actually recommend 5/30 full Synthetic as per the manual for the EJ25 5/30 GF5, 5w/40 may be used interim but highly recommended to swap back to 5/30, Kd suggest if in doubt you confer with your local dealer if your area is of extreme conditions! Oil is always a very emotive subject, imo and experience always refer to your manual, brand is always subjective, the rec SAE specifications and oil grade is what is important as is the recommend service intervals, we are not chemists or engineers that designed it built the car, neither do I believe in conspiracies to make us buy or replace an engine before it’s time. I have had nearly 20 Subis over my time and nearly as many Toyota’s and a few other brands on and off road plus have raced bikes in extreme conditions never had a major issue with a Subi other than one transmission which was an AT and not serviced as required and requested by a Subaru dealer, long story won’t bore anyone with it, they also used a brand of oil I didn’t want in my Turbo EJ at the time which both lead to court action which I came out on top of. I will say one thing re oils though and I had a good work mate who drag raced and at that time had used all the top brands and the only engine he never had blow on him was on Mobil 1, this is awhile back now 2000s and things have improved allot since then, again it’s subjective because it’s hard to really know conditions of every variable to compare accuracy, hence always follow rule 1 per manual, I do still use Mobil and never had an issue, but then I also am not heavily modifying my cars or engines, though this channel has me interested thanks as edit in following a similar build possibly. Tests are good and interesting, but conditions do vary unless testing 2 engines back to back under same conditions at same hours under same use, ai find it hard to determine if it’s oil type use or conditions that vary, it’s still a good topic and cool to see, I am a fan of motul but it’s hard to get here and expensive, but I wouldn’t choose a cheap oil just on price and engine rebuild is much more expensive than oil, I have this same argument in the dirtbike world yet I don’t suffer than same issues many do, also not sure how good it is to swap brands either on a regular basis, additives do vary and this can upset the stomach of an engine, but like dogs people think they like variety often this is far from the fact they like a stable diet that is the correct one for them. Another topic but similar. Again I’m no oil chemist or car engineer, but I know my experiences and they have stood the test of time, might be boring, but it works, I used to add ProMa to my engine oil buy haven’t done in recent years can’t tell you why never had an issue it was highly recommended again by the drag race team I know it’s a Mitsubishi product but worked for me in all my turbo cars. Anyways my 2c fwiw.
@@maverick2242 it don't matter Subaru recommends to comply with emissions. Ask any tuner that knows, 5w40 is the way to go. Just like the Subaru blue filter, not any different than a Fram. Would Subaru Recommend a Mazda RX8 oil filter? NO Is it one of the best options for our EJ engines? YES. Food for thought sir.
You should give 300v a shot. I'm waiting on my Blackstone lab sample kit. About to change my 5w-40 Motul 300v which i used for only 1 track day and virtually no DD cause.. you know... pandemic or something. I have 5w-40 Motul X-Clean about to go in for my June 21st track day, so hoping to compare afterwards.
Could be the wear you created more than the last. Also wonder if it happens to actually clean and gather contaminants better/more. I would use the same oil again and retest.

Which Rotella is recommended, got an 04 wrx a few months back, he said he used Rotella t6, car is catless, did an oil change yesterday with motul x clean 5w30 and imo the car runs better than before, a lot easier to get the car rolling and sounds a bit quieter but it's only been a day so I'll do some more driving to see if it keeps running good
@@chrisguzman7926 yeah Rotella T6 heavy duty diesel oil.
Diesel oil has much more detergent elements in it like zinc, so it will plug up a cat but is really good in gas engines without the cat. Lots of motorcycle guys run it too. Way higher sheer temp, you'll notice your oil will come out amber instead of black when you change it.
Project farm recently did a motor oil head to head scientific tests on a lot of the best brands.
Going to have to check that out!
@@Smeedia I hope you find the best brand/results you're looking for your Subie, I ran Motul excess 5-40 when I had my Stink Eye sti because it helped with less oil blowby at the pcv while having a Cusco catch can installed for peace of mind.
Amsoil!!!!!
I hate to be a negative Nancy but that year STI is notorious for crank bearing failure. Mine developed a rod knock at 27k miles and I have a few friends that had the same issue with 15-17 STIs. Well if it does happen think of the all the new content you will have for the channel 😀.
I'm already pushing the engine so its no suprise to me if it lets go. Made it past the 28K mile interval so she's still going strong 🔥😁
Smeedia Meh as long as your expecting it. I thought I’d be one of the lucky ones because I had every supporting mod money could buy along with changing my oil every 2k miles. It really seems to have to do with luck when it comes to crank bearings and a good tune to avoid ringland failure IMO. Hopefully your one of the lucky ones. I recommend if you do go and build your motor try to scavenge up enough money to do the heads as well. I did just some mild bc272 cams, gsc valve train, and some pocket porting and it makes a huge difference up top. Best of luck and keep up the great content!
I was talking to my tuner about this also and it all seems to be luck of the draw with the 257s. When the motor does let go, gling to buy a IAG block and machine and build the heads valves, springs and cams essentially. When the car qas on the dyno we pretty much maxed the OE Cams out
So just to let you know I have post in a few the Subaru groups about my oil reviews. Thus far the Subaru oil and Amazon basics did the best in terms of wear protection and all that. The block in my WRX did start eating some of the motul oil and right now I'm running amsoil so I'll let you know how that one goes in a couple thousand miles.
Please do let me know! And who are you running tests though?!
@@Smeedia blackstone of course!! trying to keep a good control over certain aspects of this experiment. as soon as im out of fb jail, ill repost it to the group
Oil companies gotta love you 😍 , given how frequently you change oil! Oil life and contamination also relies on the quality of filter in addition to oil temperature, fuel type, A/F ratio, engine internal health and driving style ( 🔥 or 🐇) as you explained. Well done. Are you using the OEM filter or the more expensive STI filter; it's $$$$ at about 5 times the regular OEM. Curious are you going to test Subaru OEM oil? It is a full synthetic. Last but not least oil cooler addition might also help out too; cheaper than a new short block.
Ive got the perrin oil cooler that I still need to custom fit on the STI Because it won't fit with thr FMIC and I want to test both thr Subaru OEM and Motul Subaru OEM Oil that they made for the S209 🔥😁 as for filter I use the prove filters 🔥
Amsoil are pretty good. I'd like to see what's the number on that brand
Have them on the list one of the next ones to test 🔥
Amsoil just won one of the largest oil tests recently. Beat pennzoil platinum, royal purple, redline, mobil 1, etc etc
@@Smeedia literally just going to ask about this. Would be great to see
Have you tested Amsoil? All I’ve been running in mine
My red flag is for this oil is 1/3 less miles, more wear indicators, they did not recommend extending service, while they suggested easily increasing change interval by 50% of the Castrol.
If I want to be kind to motul, it was the 'clean' version, and maybe it cleaned stuff ... but nah :)
My desire is to test mobil 1 extended performance high mileage.
The fuel in oil is usually from excessive idling, short trips, many cold starts. If you get an hour highway drive a time or few a week will burn off the fuel contaminants.
Guess this is sidelined with all the engines getting pulled in your garage :p
Also could be attributed to the fact that the car went on the dyno before that oil was sent out, don't remember if I mentioned that in this video or not😅 hopefully can start this back up soon with the 05 STI
Schaefer's is the best for Subaru engines! Find some tests or give it a shot brotha. Has much higher lubrication than others.
Have heard great things about it! Next up is amsoil then shafers 🔥😁
@@Smeedia Awesome! I'm following the series too see what kind of results you get. Also, what is your opinion on weights? My local performance shop is also home of the famous "GetADomTune" and he recommends 5w40 which is what I've always done.
5W/40 is what I would suggest. Its a little more viscous so in theory it helps lubricate the bearings on the crank a little better for a little longer 🔥 and Dom is super knowledgeable have talked to him several times
@@Smeedia Yeah I noticed your running his cyl 4 cooling mod right? Love the channel. Awesome content and recording skills too.
Thank you! And yes 😁😁
Awesome video!! Keep coming
I hope this series is still going and that you eventually get to Redline.
Been slacking on it but will be picking it back up soon 🔥
@@Smeedia Absolutely love your content! Keep up the good work!
Use redline 5w-30 you won’t be disappointed.
They add titanium to the gold castrol edge btw
Iron is Fe, great vid man!!!
Thank you! Was riding the struggle bus today 😅
Interested to see this i run amsoil full synthetic 5w-30. Keep up the good content. I made this comment on a your wing video. But would you say the apr gtc 300 would look better with or without removing my oem trunk lip?
My vote is still with the lip 🔥😁
@@Smeedia That is what ill go with :D
can you tell me what the real use of this test? and but the way i saw a lot of different oil tests no one give you the truth but the one with pressure test on the rotor i think give you an indication at lest. one test motul is the best, another test shell is the best, another test castrol is the best just use the one that have the specificacion for your car and that'it.
I’ve tried a few brands now, I’ve had the best luck with Castrol edge. My car hated AMS and motul
Casteol did well for me as well 🔥😁
Motul X-Clean EFE is SN Plus which is crucial to prevent LSPI, I don't think Castrol Edge is?
Great video...i would also consider some of that castrol was left in the engine and mixed with the motul
Very possible that some was left in there 🙏
I'd be scared to test my oil haha. Been running straight e85 for 2.5 years with 305whp on a ej205 (stock bottom end). I'm sure there wouldn't be great results lol, but its running flawless though.
As long as she's running strong that's all that matters!
Hi bro! Thank´s for the videos, great support for engine choice.
Anytime! Glad the videos help! 😁🔥
Is there a playlist of all your oil tests please?
Yessss! Been waiting for this video🙏🏽
😁😁😁😁
Hey man awesome video as always. Did you ended up doing comparison between Castrol's GTX and Edge?
Unfortunately I did not, I need to get that oil tested though 🙏
Japan engine street racing , Motul 8100 X cess sae5w40 / run perfect engine clean !
Motul 8100 X cess 5w40 best oil
Thanks for helping me change my oil dad
Anyime 😉
Thanks just ordered my oil kit.
Well worth it!
I understood Molyb to be an additive.
Just a little FYI. This oil is 100% synthetic. Which Castrol is full synthetic is NOT 100%. It's closer to 25-30%. Synthetic
I love your videos!! I’ve been reading all this comments, I already need an oil change, I own a stock 2015 Sti Limited and previously I used Motul X-Cess gen 2 5W-40. I need your advice, should I keep using the same one or should I change?
Swap over to the 5W40 Xcess 👌
@@Smeedia thank you!!
Best not to come to any conclusions same oil as a baseline to compare apples. I am curious as to the actual element levels to potential failures.
I know most sti guys run the 5w-40 motul. Maybe you’ll see better results with that? Great video tho, love the content.
Thank you! And i normally run 5w/40 but some of the samples that ill be testing will be 5w/30 in theory the more viscious 40 should provide better lubrication between the crank and bearings
yep i use 5w40 for years now feels better than 5w30 too
@@layesse1 really what kind of weather are you in? i just did my first oil change with 5w30 but mostly for warranty reason
@@tian2339 ran it when i was living in Connecticut even in sometimes under 10 degree weather for years still using it now that im living in Texas where its 90+ alot u will be fine 100% i only use motul xcess 5w40
@@layesse1 thanks dude!
X cess 5w40 built 07 sti my fp green and motor loves the oil also not much piston slap on cold starts once it gets to 130f the forged internals a quiet 👌
Glad to hear! Running the same oil in my 05 with an RA block, built heads are a little noisy with the Xcess so curious on swapping to Lucas 👀
Believe it or not, Fe is the periodic symbol for iron.
Introducing your 🐔 can bring much more viewers 😂😂😂 good to see your channel growing my dude!!!👍👍
Thank you! Been crazy to watch the grwoth but definitely enjoying it 🔥😁
Lmfao the chickens had me 🤣😂
Walked back there to see what they were doing 😂
Man I have a doubt. I have a conventional aspirated engine V6 car. In that case, would Motul oil be better than Castrol Edge? I mean, is Castrol better for turbo engines, and Motul for aspirated engines?
Skip to 4:50 to see results
What about running the stock Subaru certified oil aka the rebranded idemitsu oil? You should try that.
Also Make Video On MOTUL CRDi Love From India🇮🇳
I'll check it out 🙌🔥
This video series is a good idea, but I'd say it's hard to use the STI as the "control" unless you left the car as is for every test. You've added a million parts in recent months lol
Also, molybdenum going down is a bad thing I thought. Moly is a friction modifier. I could be wrong though, I know very little about oil.
The only thing that should really have an effect on oil life is the ethanol and new tune on the car outside of that there shouldn't be much that effects it. And from what I found increased levels of it tend to come from the rings. But It could also be an additive
@@Smeedia more power = more strain and wear on the engine. You should definitely try to send the oil off with the same amount of miles or hours driven on every sample. Parts changed, fuel changed, tune changed, and miles between oil changes/samples inconsistent. Hard to draw any conclusive data from that.
Thats the goal, but had to change the lil this time around before going onto the dyno 😣
How do you feel on the Motul 300V 5w40 Racing Oil? This is the oil the S209 comes with from the factory.
Just got some 5w-40 Castrol.....let’s see how much better it will run than the 5w-30 castrol
I've got the 40 on the list also to test 😁
WOW!!!! this is great!!! Very very cool man👍🏻 hey did I see E85 gas cans in the back?? Yeahhhh buddy!!!
Wait, you have chickens???
😎👍🏻👍🏻
Haha that you did! 😅😁 neighbor's chickens 😅
Smeedia dam neighbors 😂😂😂
Smeedia
Have you try using eneos?
Eneos and motul got the same price..
Which one will u use?
Hey. I have a 16 wrx. Copper has been trending up the last 3 oil changes. I’ve only monitored it for 3 since it’s been tuned for flex fuel. Went from 17 to 42 to 61. About 3k miles oci. Other wear metals normal. No lead. No tin. Iron in the 10-20 range and actually trended down last oci. What could be the source of copper? No new oil cooler. Thanks!
Next time pay the extra 10 bucks for a TBN. That’s the most important part of this test and you skimped out on it. Put a couple of filter Mags on your oil filter and re-test. Metals will be reduced.
I use to do it for free at my old job, we had a TPN Tester and I could pull results for free. Just never added them in because test results were slow to come through.
Save your money guys, run Wal-Mart 5w30 full sin., and oil filter 👍 after 15k no issues, and l have a heavy foot, my STI is 2016 😉 l change oil & filter every 3k
Walmart has their own brand of oil? 👀
Made by Warren distribution, right?
Penny wise and a pound foolish! You shouldn’t have problems after only 15k miles, but if you want your motor to last I wouldn’t go with the “cheap” oil.
@@Smeedia Supertech but Costco's Kirkland brand is same Warren distributer but you get 2 pack of 5 quarts ~ $21-$30 ymmv.
Hi dear motul 8100 or shell helix ultra which one is more better for Diesel engines
used motul efe 5w30 on my 2018 sti had 20k miles when i changed, i kid you not my oil was pitch black within 1.5k miles.
i do drive the car a bit hard only sometimes tho never really go past 4k unless highway merging.
gonna try amsoil signature next
Amsoil is next then shafers 🔥, the motul gets dark QUICK
Damn I just used the efe on my oil change, car runs good but now I’m scared because what you said lol. Damn.
i know this is an old ass comment but i wanted to pitch in and say that if your oil looks like new or anything close to new when you drain it for your normal interval oil changes, it's not a good oil. oil color doesn't mean everything, but if it's coming back completely clean, it's not doing its job. it's supposed to absorb contaminants so it can transfer it into the oil filter.
Amsoil or motul or LIQUI MOLY??!
hey i just use the Subaru oil, is that a bad thing? i thought it was healthy
Chickens make that noise usually after laying an egg, it’s their egg song. 🐔🐣
Good to know, explains why they're always making noise 😅
Moly is actually a common additive, probably not a wear metal in this case
so do you suggest moly additive after oil change ?
@@HS-sr9ww probably not necessary, many oils already have it, not worth the money imo, but it won’t hurt ur engine and may make it more quiet.
So i been using oem subaru oil for awhile 2020 sti about 22k on her. No aos yet or anything. Only intake and catback with just a cobb ots tune (for now) . So i tried the 5w30xclean this time around and noticed that at about 2k ive already went through like a qt which has me kinda worried. So im thinking ill just switch back to the oem until i can find another brand to try. I havnt sent a sample out yet because i ended up topping her off with some shell oil or mobil 1 until i change it again. Anyways going to grab an aos asap and just wonderin what your thoughts are like maybe my car just doesnt like that oil? Lol. I live in new england and its just starting to get really cold . I got a 30k service comin up soon thats covered so ima have em check it out than but obv warrentywise they could give me issues. Anyways just curious on your thoughts i know you said the report wasnt as good as you expected on that one. Any insight would be much appreciated. Thanks man
Please rotella t6 next ❤️
It's number 3 on the list so it is coming up 😁
Hay Tanner, what do you think about the valvoline vr1 synthetic?
I'm due for an oil change, so I might start tryin out different oil.
Not a bad time to do so 😁😁
Add Castrol 0w-40 euro to your check.
Will do! 🙏😁
don't run energy conserving oil in a Subaru. 8100 xpower or v300, Fuchs titan race pro s, or get castrol edge supercar. you want oil with a higher zinc additive as we run bucket shims and need good oil film strength.
Appreciate the input! Only ran through the car for 2K miles for the test but not using it again! Good to know and hopefully will help others as well!
Gold choice for Motul, but should've gone for 5w40.
5w30 is way too thin. Big no no my friend.
Have 5w/40 on the list but went through the 5w/30s first. Outside of testing oils I normally use 40
Well Subaru actually recommend 5/30 full Synthetic as per the manual for the EJ25 5/30 GF5, 5w/40 may be used interim but highly recommended to swap back to 5/30, Kd suggest if in doubt you confer with your local dealer if your area is of extreme conditions!
Oil is always a very emotive subject, imo and experience always refer to your manual, brand is always subjective, the rec SAE specifications and oil grade is what is important as is the recommend service intervals, we are not chemists or engineers that designed it built the car, neither do I believe in conspiracies to make us buy or replace an engine before it’s time.
I have had nearly 20 Subis over my time and nearly as many Toyota’s and a few other brands on and off road plus have raced bikes in extreme conditions never had a major issue with a Subi other than one transmission which was an AT and not serviced as required and requested by a Subaru dealer, long story won’t bore anyone with it, they also used a brand of oil I didn’t want in my Turbo EJ at the time which both lead to court action which I came out on top of.
I will say one thing re oils though and I had a good work mate who drag raced and at that time had used all the top brands and the only engine he never had blow on him was on Mobil 1, this is awhile back now 2000s and things have improved allot since then, again it’s subjective because it’s hard to really know conditions of every variable to compare accuracy, hence always follow rule 1 per manual, I do still use Mobil and never had an issue, but then I also am not heavily modifying my cars or engines, though this channel has me interested thanks as edit in following a similar build possibly.
Tests are good and interesting, but conditions do vary unless testing 2 engines back to back under same conditions at same hours under same use, ai find it hard to determine if it’s oil type use or conditions that vary, it’s still a good topic and cool to see, I am a fan of motul but it’s hard to get here and expensive, but I wouldn’t choose a cheap oil just on price and engine rebuild is much more expensive than oil, I have this same argument in the dirtbike world yet I don’t suffer than same issues many do, also not sure how good it is to swap brands either on a regular basis, additives do vary and this can upset the stomach of an engine, but like dogs people think they like variety often this is far from the fact they like a stable diet that is the correct one for them. Another topic but similar. Again I’m no oil chemist or car engineer, but I know my experiences and they have stood the test of time, might be boring, but it works, I used to add ProMa to my engine oil buy haven’t done in recent years can’t tell you why never had an issue it was highly recommended again by the drag race team I know it’s a Mitsubishi product but worked for me in all my turbo cars.
Anyways my 2c fwiw.
@@maverick2242 it don't matter Subaru recommends to comply with emissions. Ask any tuner that knows, 5w40 is the way to go. Just like the Subaru blue filter, not any different than a Fram. Would Subaru Recommend a Mazda RX8 oil filter? NO
Is it one of the best options for our EJ engines? YES.
Food for thought sir.
@@maverick2242 you are correct
@@joralex just follow the recommended oil weight, they engineered the engine not the tuner.
You should give 300v a shot. I'm waiting on my Blackstone lab sample kit. About to change my 5w-40 Motul 300v which i used for only 1 track day and virtually no DD cause.. you know... pandemic or something. I have 5w-40 Motul X-Clean about to go in for my June 21st track day, so hoping to compare afterwards.
Definitely will, have it on the list as well. Let me know how your results come back 🔥
@@Smeedia WIll do, hopefully the sample kit gets here soon. Random question; steering wheel? Which one is yours?
I use thr OEM Type RA wheel 🔥😁
Smeedia nice choice. Did you ever think about bumper swapping 18+.
I have but i would want to trade my set up + Cash for a 18+
You should try Valvoline VR-1
I'll add it to the list 😁
I thought Motul X-Clean was mostly for FA20s and Motul X-Cess was for the EJ? This is for 5w40.
It is used more in the WRXs but some also use it in thr STI as per manufacturer specs so still decided to test them
The way you pronounced the metal at 6:46 🤣🤣🤣
Lmao 😂😂😂😂😂 I couldent help it 😂😂
Use Ravenol.... It doesnt lose viscosity
Castrol is the worst oil in the world. Motul is the best!💗💗💗
I like to use mobile 1. I watched a video from a TH-camr using different oil going though torch test along with heat and cold race ect.
I've seen similar tests done and the results are always interesting to see! 🔥
Go watch project farms youtube oil analysis mobil 1 got it's ass kicked
Could be the wear you created more than the last. Also wonder if it happens to actually clean and gather contaminants better/more. I would use the same oil again and retest.
Using a similar oil just the standard XClean instead of the EFE so I would expect to see similar results but we will find out on the next iteration
Can you please try Amazon Oil and see how it compares for a Subaru?
I'll try it in the girlfriends imlreza, dont know muxh much I trust it in my STI 😅
Been excited for the giveaway
Up and live on IG 😁😁
At list, is a good oil or not? 😂but the way test the motul 8100 5w30 x clean efe is the best
I don't see any updates on your channel how did the second test go?
Motul might have picked up a lot of left over contamination from the Castrol
Very possible, need to run another test
Royal Purple HPS with Synerlec and Zddp please! Completely different animal compared to the Off the shelf API compliant Royal Purple
I won't do Royal purple, had 1 batch that I used years ago go bad and coagulate on me 🙃
