- Made a quick POV drive vid with 18 STi and the potential ringland issue everyone is concerned over. After hours of research, I've noticed patterns in those who's engines exploded. Here is my conclusion and how to prevent it.
Also a good video to show how the Invidia R400 catback sounds (windows down, catback only). I apologize if it's hard to hear, but that's why! A very high quality / bassy exhaust tone. I love it.
If you can't afford premium gas you have no business owning a high performance car
Hands down, the best advice I’ve heard for STI owners.
I'd like to mention that MAP performance offers a stage 2+. They have their map intake, downpipe, and a tune for both. Cobb does not have that option. Obviously that is the max, after that you need to upgrade the injectors. But 300+ whp/torque is a great place to be at with an STi.
Great video buddy, couldn’t agree more 👍 I’ve just had my third oil change on my 18 STI and it’s now done 7800 miles. I run 99 Ron (95octane) fuel always and have set my rev limiter to 4500rpm, I personally think there is no need to rev it to 6900rpm. Going stage 2 in February and not having a cold air intake, no need like you say, as stock air box is the best and safest 👍
4500 rev limit? The turbo just got spooled up! Let her rip man! A WOT a day keeps the shop away :-p
how did you set a rev limiter? is it with the cobb port?
How incredibly fucking lame. Why buy a car like this? For the wing? Lol
Why the hell do people buy this junk if this is the case
Always great videos keep it up bro
What people do as well is on cold start sit at idle for 5min and thats actually doing more damage. You should start up wait for all the lights to go out and then drive normally by not going above 3rpm until reaching operating temp. The engine will warm up quicker by doing that then sitting at idle.
Don’t worry about it. Perform maintenance. If you modify, do it right.
Your octane description is wrong. The car requires 91 octane, and prefers 93. So 91 is the minimum, but 93 will give the best performance. Problem with 91 is that if for some reason you get a bad batch, or your fuel goes too long in your tank, etc etc then you're putting the car at risk...
Running 91 in your european cars will stuff them minimum 95
I'd really prefer 93 octane, but it is absolutely NOT available where I'm at. It is NOT required by Subaru. Premium fuel is required. I live at about 5000ft elevation. The air is thinner here, so the way 91 octane works here is better for the engine than 93 octane is in New York, or anywhere else at sea level. I'd still love higher octane for even more insurance against engine knock, but I'm not causing any issues using 91 octane at my elevation.
I guess you live in rural Colorado?
@@nicolathonathan770 nope
Great video!
what if you just use shell 91? out here in AZ and plan on just keeping it stock besides coilovers/wheels and ride the warranty out
Good video bro
Today , 12/30/2020 my 2018 sti 45,000 miles completely stock engine went due to ringland failure. Im not sure if the dealship went cover it under warranty. They did my oil changes. All I here is that do everything possible to make not fall under warranty. Also always 93.
Update they covered it no issues
The term "warranty voided" is not how it works. Warranties DO NOT get voided. Warranty coverage for specific issues can be denied if it can be shown that YOU caused the issue by running aftermarket parts, did an aftermarket tune, etc. That is denied coverage, not voided warranty.
Regular oil changes, AOS, don’t hammer it under 3k rpm, put fresh gas in your car from a busy gas station, and get a dp with a high flow cat
Should I be scared to get a 2019 sti? I have gone down a rabbit hole of just seeing a lot of problems with the car.
Dont buy it!
I did get a 2019, and I hope you did too. The haters all ride skateboards.
@@easkeybikes1966 I did actually! What a journey it has been! It has had no issues so far knock on wood. Have about 38k miles on it along with stage 2 with dyno tune for the past 20k
would have been nice to hear what your were saying..
Dump trucks, mini Van's and pick up trucks man always one of the three
i heard the 2019 sti fixed that is that true? im looking to buy one soon .
I doubt. Maybe they'll fix it on the next coming model
The flaws in these enginese probably can only be abated and not avoid as originally built. Changing the oil early may help. Using the recommended octane will help. Not running a non-OEM engine map with the additional stresses it creates helps. Letting the engine reach fully operating temperature before using the full power range helps. Letting the engine cool down after use helps. Nonetheless, these engines will continue to have failures until the engineered in issues are addressed by Subaru or aftermarket engine builders.
Love your sti red is a great color on it I have a red 18 as well haha
Yes its an older video, but you only just barely touched on the number 1 reason for headgasket and ringland failure in these engines. people NEED to realise, that their intercooler does not even begin to function until around 50 km/hr (35 M/hr for you americans) Doing launches, parking lot drifting, pulling trailers ,etc etc - anything that puts you into boost, without first travelling at min speed, will cause your air intake temp to skyrocket, and thus cuase either/both pre-detonation and over pressure in the cylinders - thus causing internal damage. The next biggest reason for the engine failures, is slapping on a bunch of "bolt on" modds,but not doing the internals. People HAVE to remember that Subies are a budget car, and therefore were built to handle the factory power only. There was no "overbuilding" done, to keep the price down. it is fine to do a bunch of modds to the car, just make sure you start at the bottom - not the top!!!!!
Engine will use oil when it's new as the rings haven't seated yet.
might wanna roll up the windows next time
93 octane? Damn they don’t sell that in KS
You shouldn’t rest your hand on the shifter when driving. Let me guess, your left foot is rested on the clutch the entire time also?
It's only detrimental if you're applying too much pressure to either / or. Should be common sense by now.
how many quarts of oil does the car take?
menswearhous 4.5 with filter change
@@faekz do you fill the new filter up a little before putting it on?
menswearhous honestly you can but I don't bother I just rub tiny bit of oil on the rubber seal. The engine only runs for 5, seconds or so before it gets pressurized.
If I keep it stock what are the chances the engine will blow up
lol with proper maintenance and gas, and not beating the piss out of it all day everyday, it should easily last 100k+ miles
Wait you put a slip in air filter you’ll need a turn?
it's not recommended to run even a K&N filter without a tune. This is true. It will effect the air / fuel ratios and timing, hurting the engine over time. This is why most people blow up their STIs / 2.5Ls. They run shit gas and drop in filters or intakes w/o tunes
@@defaultdaniel it’s the same as the stock air filter still inside the stock air box
@@dougl4253 if it's the same filter then you obviously wont have problems. Any high flow will cause long term issues
Why is your speedometer flickering and Is that common on the sti
It's from the camera
Did you tune your car when you put your exhaust
It’s just a cat back. No need.
Their is only one thing that prevent engine problems is don’t MODIFIED the car ...
I disagree... dont mod your car with out a good tune!
U don't know what u talking about u cand do intake as long as u get tune etune or Cobb tune until u can get pro tune
looking to buy a new 2019 sti but where i live in gatineau quebec canada we only have 91 octane
I personally wouldn't risk it long term. I've read a few reports where tuners tested the new STI engines, and said they saw significant knock occurences in 91 oct and lower vs 93 oct. The car is meant to run off 93 oct, especially when it's hot out. If you must, you can always add some octane booster or get it tuned to 91 oct. Truthfully I wouldn't want to do either to a brand new car. Or you can just find the best quality 91, drive it, have a good warranty, and keep it stock.
it suck then cause the only 93 oct neer me is 30 min away but they sell sti in my town knowing we only have 91 oct service station. thank you for your answer
Run Shell 91 V power.
I own a 2018 sti, and I live in Laval Québec. Shell 91 V power is your best bet. Don't run anything else other than shell 91 if 91 is the only available gas near you.
Why? shell 91 is real 91 octane with no ethanol.
2018 sti here. I live in ontario shell v91 is good.Its all i run. Read on toronto subaru forum that its fine. Ive got over 50000km and no issues. You can run esso 94 octone for more horsepower but shell v91 gives you better economy. Depends on your driving. just dont beat on it.
Here in Israel the minimum Octane is 95. And sport cars use 98 Octane.
Shiiiiii
You mean palestine?
@@ahmadalmajid6860 What's that?
2018s have revised engines we good haha
artz Sti no 2019 has revised ring lands which are slightly thicker. 2018 type ra has the same motor as a 19 sti a normal 2018 sti
@@carlotlife5013 i work for subaru and taken them apart 18 and 19 are the same RA is a different animal
artz Sti lol you’re wrong bud. Do your homework
@@carlotlife5013 im sure it hurts u to know the truth its ok
artz Sti lol I’ve done my research I OWN a 2019 STI it has a revised 3rd gear over 2018 and previous and new intake which gives it the 5 extras HP over previous years just like the 2018 RA has and also thicker ringlands just like the 2018 RA, the non RA 2018 and previous DONT have what I just listed only the 2018 RA and 2019
All great points for the youth. But I"m unsure why 18 Sti w AP wouldnt have stage 2+. My 11 Sti w V3 AP has stage 2+ for intake and DP. Just droppin info. 👍 great video btw.
Because the fuel injectors are overwhelmed and will possibly, if not very likely, lead to running lean and possibly cause knock and ringland failure.
Subí bother ✌🏼🚗 your 🚘 look 🔥🔥🔥
There is no preventing ringland failure in this junk engine. Ours went at 69,000 miles. It was completely stock. It's a garbage design and is the most unreliable car I've ever owned in 50 years.
I had a stock STI. Always 100octanes. Engine dead after 17000km 🖕🖕🖕🤮🤮🤮
And how bad did you beat on it ??????? LOL
