- Does stp pro series intake valve cleaner work?
We show 2 different tests, 1 test before and after intake valves on a direct injection engine. The valves used for this review have the worst carbon buildup inside the engine. These carbon deposits have the most buildup I have ever seen. So this will need to be the best intake valve cleaner made in order to clean the valves. The second test we take the variables of the car out of the equation and use new valves with oil vapor that was saved in a oil catch can. Next we pour that oil vapor over the valves and use a torch to bake it on really good.

How to use stp pro series intake valve cleaner?
We show the use but Always follow manufacturer's instructions.
Today on Nates interactive auto we find out just what is best for intake valve cleaning.
In previous videos we tried Liqui moly valve clean and crc intake valve and turbo cleaner vs seafoam spray. - ยานยนต์และพาหนะ

I really appreciate all of your kindness & time it means the world to me in these trying times. I tried to speed it up so you don't waste valuable time.
Can you test a Purolator boss filter
I did that in a recent video
@@NATESINTERACTIVEAUTO do you remember how long ago was it? I'm looking for it now
You did the stp video !!! I like that you read the comments man. We appreciate you
Trying times?
Nate, congrats. Your channel's really growing. I'm glad YOU haven't changed, though. Keep pointing those fingers at the engine....love it! Great video!
For those who are interested, this is from the MSDS:
Butyl cellosolve 25-40%
Xylene 25-40%
Ethyl benzene 1-10%
Polyether amine 1-10%
Alkenyl amine
Genius thankful
Nice, the cellosolve is what the old gm top engine cleaner was, Best stuff. I can smell the xylene when using it too. I've been using it at my shop a bit lately om these gdis. Its just too cheap, easy, and effective.
@@jeremyr7147 just curious if you've serviced 2.0 T VW engined for valves mainly with this?
@@RipPhillips no, but it will work equally. I just finished a chevy impala 3.6 DI.. the stuff works. I have been getting them in about 150k mi. W/ no records of cleaning.
I like this because the engine is running while dispensing. It wont blow off big chunks like doing a soak. If its bad i would do 1 of these before the oil change 2 or 3 times, then move to a full GDI soak if you want. The soak will drop bigger chunks. So I'm doing these stp cans most the time till someone gets caught up.
Last time i did a crc GDI soak on a really sludged 150mi hyundia i got worried and stopped at 1/4 bottle and chunks were already pinging at that point. Like marbles in a can.
The key to a safe application is getting the engine and catalytic converter mostly as hot as possible. Set everything up so your ready to hook up after a hard drive to get the converter hot. That way chunks will vaporize when they hit it..
When finished drive moderate the first couple min then get into it a few times. For about 15 min of driving then change the oil afterward.
@@jeremyr7147 Hey man appreciate the feedback and detail. New to this platform but want to take care of it so anything helps. I assume drive slow and then harder to reheat and help burn out carbon broken loose before high rpms disloding cold chunks in there then? Thay all makes sense tho.
That looks like it works better than most I’ve seen you and others use. Nice video, Nate.
I was really surprised at the results, a subscriber told me to try it that its the best so I gave it a try. I want to let you know all of the kindness means more than you can ever know to me.
That was impressive from the STP. Great video Nate.
Impressive. Best ive seen on the tube thus far!
Thanks for doing this for us! Great results!
Impressive results on the STP treatment! I would probably say the best results so far!
Scotty Kilmer recommends ATS fuel cleaner. 🤷♂️🤷♂️
It’s really expensive it’s $40 a can.
@@adanlopez1011 it is!!
@@Unplugged704 Scotty kilmer is a walking heart attack
Xylene is good stuff. Also, PEA or polyetheramine is one of the ingredient to look for. It breaks carbon down by dissolving instead of breaking off larger pieces. Larger pieces would be destroyed in combustion and sent out the exhaust valve. The most common issue I’ve seen in the field is melted cats or contaminated upstream oxygen sensor.
- MAKE SURE THE ENGINE IS AT OPERATING TEMP BEFORE USE. Also not recommended on vehicles with worn spark plugs (over 80-100k mi) - Can cause pre-ignition and/or detonation.
- For non-GDI engines, in preparation for intake cleaner, run a bottle of STP ULTRA 5-in-1 (25-50% PEA) or Redline Si-1 (28-34%) in fuel tank (Follow instructions on bottle!)
- Fill fuel tank and perform induction cleaning
- change oil
Colin...What source did you see the STP = 25-50% PEA? and Redline 28-34% ?
Care to share the brand you’ve seen that’s got a good amount of PEA?
I was just thinking to myself a few days ago, "It's been awhile since I've seen Nate stick his hands where they're not supposed to be while warning us not to stick our hands there." 😄
I love it great way to show dangers that I don't recommend.
Okay I'm confused. How did you scope those intake valves? Were you able to get the scope in the side of the intake all the way down those 12-in intake runners into the head?
😂😂😂
how are u getting into the valves to take photos? did u remove the manifold?
This video has peaked some interest . I'm glad I have my catch can too brother
It works, as demonstrated, the part that STP doesn’t tell you is that ‘chunks’ will break up and get into your combustion chamber and some will lodge between the Piston rings and cause ‘Oil burn’ issues. Also, change the Oil a day later and you will see a lot of broken off carbon bits in the bottom of your Oil Pan! So yes, it works but…
So changing the oil will resolve this issue? I’m thinking about doing the this intake cleaner
@@Cummata it will remove the chunks but in my case pieces were/are wedged between the piston rings and cylinder walls and it’s been consuming oil ever since… 7 Oil changes later🤦♀️
@@user-kb8gh5jv9t so basically it’s not worth it to do the cleaning?
@@Cummata I think its high risk due to the potential of Oil burn issues. I personally will do the Walnut shelling next time…
@@user-kb8gh5jv9t how many miles was on the card when you did the service?
I currently have about 105k so I know there’s a bunch of build up which may cause a problem when it starts chunking off 🤔
Keep up the goodwork Nate
Really nice. Would like to see liqui moly pro line throttle body cleaner as they say it's cleaning the valves as well.
subscribed! I like the results and will try this beforeCRC
Definitely giving this a try on my honda Gdi engine. Truly appreciate your videos thank you.
Might clog your cat
@@davidvickers8425 what cat😶
@@2isjesus957 catalytic converter, anything else would be animal cruelty.
Do you think this would work if the intake manifold is off where the valves are visible where I could just spray it on the valves? Id really like something that foams up that I can spray in the intake runners.
Holy crap that really cleaned those valves !
Fantastic video. I'm planning on buying new car with 2.7 turbo with DFI and want to have a preventative treatment plan and this looks fantastic... Probably do it every 10 to 15k miles.
This stuff is fantastic for the 2.3 l EcoBoost mustang!! Highly recommended if your car is over 50,000 miles! I used to have misfires every couple of weeks. But when I added this engine cleaner into the mix all those misfires disappear and the car's engine is much more responsive! Again, highly recommended
im having this exact issue with mine
@@Savageslash1234 Make sure your spark plugs are gapped correctly as well.
After the treatment should you change your oil 🛢?
Now how does this compare to CRC or berryman 2611 and do you recommend you change your oil after this treatment?
Love these videos man, keep making videos I got all the hope for you man. Great content
Nice video Nate !
Gonna give it a try thanks!
Everyone with an EGR valve should do this
Just block the EGR, problem solved...
This is amazing! My girlfriend's GTI is in need of a walnut treatment - this might just save us from having to take the whole car apart!
What he isn't telling you is all that carbon that he's cleaning goes into your exhaust, through your turbo and could plug your cat if you have enough carbon.
@@RepairGeek it could also score the cylinders if the carbon is hard enough. I wouldn't do this with any engine that has alusil cylinder sleeves.
I just sold my GTi after having it few years. Carbon buildup on these engines is ridiculous. Do yourself a favour mate and fit a catch can.
No way. Nate, is it really that good cleaning valves? That looks a lot better than anything else you tried.
It helps that I clean them periodically not to allow it to much time to be baked on. Otherwise it may take me more than 1 treatment. Thanks again for your time.
A subscriber told me it was the best in a comment so I told him let give it a try.
Great video and good information I have the same GDI Kia engine as in the video just can't tell if it's an Optima forte or another Kia i have a 2013 kia optima and I've been using STP fuel treatment in my gas tank... i may try the intake treatment as well
Good show Nate!!!
GM I need my morning car info expert , Nate have a great day
I already did this treatment to my car before seeing this video. And YES it made a very noticeable difference on my GDI Turbo engine with only 10k on odometer. So easy just follow the instructions correctly. Hard to screw process up.
I'd be careful on turbocharged cars.
@@Too-Gq-For-You Yes considering what goes into the cyl and doesnt get burnt goes back out the exhaust and then drives the turbo it would be risky.
Is it a good idea to use STP fuel injector and carb treatment on 1972 volkswagen super beetle? I just want to make sure that the fuel lines are fully clean before my dad and I start doing maintenance on it.
How do you aim the tube at the throttle plate. when you stick it in between the boot and the throttle body it's going to be facing the opposite way. you have to bend it 180°
What scope is that you used to see down by the intake valves?
Out of all the valve cleaning products that you’ve tested what would be the number 1 product that you would recommend to all your viewers? For the best results.
Wow.. unexpected results!!
Good results... keep on top 🌹
Where do you place the STP nozzle when you have a turbo charged direct fuel injected car? I've got a MK7 VW Golf R and carbon build up sux.
Good show Nate.
Nate thanks u save US alot money and time, can do it by my self
Save yourself even more money by not even bothering to clean your valves just rev it a bit harder more often.
Should I do this after my turbo on a 2019 volkswagen golf alltrack? Theres a MAP sensor after the throttle body which is on the front of the intake manifold. Could I remove that sensor and inject this stuff there?
Wonder if you ran it back to back like instead of one can do one can drive it n then repeat it a few times like two or 3 cans ...wonder if it would get em even more clean???
These products must do something, otherwise some car companies wouldn't use them like Subaru (Upper Engine Cleaner). Better results than I would expect. Impressive!
Also while doing this on a car that has a inverted manifold like this one you want to every now and then race the engine as to make sure the cleaner isnt puddling in the manifold.
Great video!! Ill try this while im at 20 thousand miles before they get too gunked up for some preventative maintence ! :) thanks man!!
I don't have a GDI engine, but I run a bottle of GUMOUT for GDI engines in the fuel tank after ever oil change. I may put an oil catch can on the engine anyway just to reduce the oil vapors going into the intake manifold. I had a carburetor on a generator get jammed up from the vapors routed into the air intake from the crank case, so I re router the vent through the front of the air cleaner so it passes through the pleated air filter, solved that issue.
Would this be safe to run thru a supercharged engine like a gm lt4? Afraid of the chemicals stripping off the Teflon coating on the supercharger rotors.
Does this process affect your MAP sensor down steam of the throttle body
How is it that those liquid doesn't accumulate inside & flooding the intake runners before it reach those valve higher up there? Could end up hydrolock the poston...
Hmm having seen a lot of these cleaning videos, I find it hard to believe it did such a thorough job cleaning the valves.
It's literally 8, 10mm bolts to remove the whole intake plenum, Kia's are great to work on and there's no way he snaked that endoscope through the intake manifold, he took it off. You would spend more time trying to to get it to bend in the impossible angle you need versus the 3 minutes it would take to take off the manifold
It's got to be true I seen it on the internet
I agree. It's very difficult for me to believe that a single application of this stuff cleaned the intake valves/ports so well. I just don't believe it.
looks good Nate. wondering how often we need to do this? I'm thinking every oil change interval or at 20k 25k or 50k intervals?
Typically every 10 k add some sort of additive. Be it intake valve cleaner or Throttle body/carb cleaner. Or whatnot. Don't use seafoam ever on a engine you plan to keep
@@josequilez5449 hey I got a bottle of berryman carb/intake cleaner. On the back it states that I can spray it into the throttle body while car is running, could I trust that it would be safe for the engine and Cat? Thank you.
Would love to see a future video on a how to video putting in a scope camera in the engine to check the valves 👍
Great video check out past video, however this depends on your vehicle. I can't observe all of the valves.
@@NATESINTERACTIVEAUTO at 1:16 you show pictures of all valves. Is that not your car?
Do I need to change the oil after I use intake valve cleaner just wondering pls thank you
Wow! May have to give this a try on my 2003 Ford Taurus with almost 300k miles. Great video Nate 👍
Hey there thank you for your time it doesn't go unnoticed.
@Zach Elder your Taurus is not DI. So it is not necessary for you to go this route. Perhaps using a quality injector cleaner added to your fuel tank would be a good idea.
Damn good video 👍 I just bought a new truck maybe I should use ever other oil change as a maintenance item
Apologies I forgot to show the drive at highway speeds for 10-15 minutes
it's cool Nate. Thanks.
A great video 😁😁, 👍 good job.
Were did you buy this as it's not available in Vancouver canada
What about the catalyst converter all the carbon go inside & plug into
1 where does it all goes? Into cats?
2 valves are steel I got it, but how about valve seats, intake and exhaust ports(aluminum ones) and moreover gaskets?
3 how this is better than kerosene and transmission oil?
Tell me how you see the valve with your camera where you introduced the camera to see i have the same car
This seems to have a good effect
I've been using the CRC Intake & Turbo cleaner, but my local auto parts store is out. I'm buying this tomorrow.
Hi ., did the stp work ?
@@Voltrondefenderoftheuniverse I think it did, but I suspect my car might be better off with a professional cleaning with the walnut shells. I changed jobs and only drive around town now, rarely going above 45mph so it seems to clog up quickly. 90% of my driving is to the grocery store (1/2 mile) or to work (2.5 miles), so the car doesn't even warm up most of the time.
The instructions say to insert the tube into the hose for the intake manifold at the butterfly valve and reconnect the hose, but my hose end has a metal insert and crushed the end of the tube. Traded it in for a second bottle and left the hose off slightly and it worked. I think I'm going to do this again this weekend, but this time insert the tube just before the turbo incase that's the cause of my hesitation.
@@jeffrielley920 ➡️ thank you for the reply 👍🏻
Need to know where to connect it on a 2017 VW Jets 1.4 to avoid any unintentional harm?
I was looking for a good product and that is extremely impressive. Sub'd.
Interesting video.
Would you be better off using an oil separater before getting too many miles on car?
Where is this product available? I can't find it anywhere.
1.4tsi cant wait to try it on
And any result ?
It would have been interesting seeing how you entered the camera through the intake manifolds.
I agree. Very curious how he gets in there
He removed the spark plugs and snaked the bore scope into the cylinder that way.
I am wondering the same thing because I watched another video that showed the same exact images.
@@reruddock
Unless you’re a magician, this is almost impossible!
Images are from the back of the valves and not from combustion chambers.
Probably just pulled off the manifold...
Will this work with turbo cars? Like a 2019 Chevy Malibu LT 1.5l T
Is that applicable for exhaust valves?
I wonder if this would also help with stuck oil rings on pistons? We have a 2006 scion tc that burns oil due to my 10k mile oil changes I would love to fix.
Dont trust this guy the photos he uses are the same ones on stp's site.
Its been proven also that this stuff has caused engines that dont burn oil to burn oil even after 7 oil changes later.
There is an awesome project with- DIY Dave- on youtube where he has spent over a year testing different products where he really does improve oil burning from a quart/litre ever 300 miles to 1000 miles. Berrymans is the one that works.
Watch and enjoy
Is it safe to use on VW GTI 2006 FSI turbo engine ?
Would this product work on an SFI (sequential injection) engine? What are your thoughts, would it make any difference or damage any internals?
It wouldn't do anything that the fuel isn't already doing. In a SFI engine the fuel cleans the valves so there is no need. This type of cleaning is really only needed in GDI engines.
Hello dear can you please test BG products specially 44k and EPR thank you
Will this affect that catalytic?
I've been very underwhelmed with the performance of valve cleaners I've seen, until this one. It appears to do what it says. I have a Kia 3.3L GDI with 85K miles, and have been looking for a way to do a decarboning treatment that works without tearing down the engine and media blasting or scraping. This looks like the answer. Thank you. I just ordered a can of it along with some other things for a routine service.
There’s gonna be a ton of carbon buildup on those valves. With that much mileage it’s gonna smoke pretty badly. But should run significantly smoother . I would suggest doing that right before your next oil change. And also do an engine flush too just to ensure it removes any carbon pieces that may have gone into crankcase.
How did it work??
How was your experience with STP valve cleaner ? Did it work?
@@AZRockRunner Best one I've found. I have a 2015 Kia Sorento with the GDI 3.3L V6, and use the STP product to clean the injectors/valves since GDI engines tend to build up carbon. Doing great at 100K miles.
@@GlassWolfLHno issues so far? Burning oil?
Is that make sense with mpi engine?
Would this work on a 2.0L NA jetta
How often do you so this Nate? How long in between treatments?? Your valves get really dirty. I see you have a catch can, why do your valves still get very dirty???
Used the Pro Stp intake valve cleaner on my gdi engine yesterday. Feels like I added 10 horsepower!
Jel' to zbilja funkcionira?
@@markosedlarik9553
Da
How many miles/km did you have when you cleaned it? What car/engine?
What car was it on ?
How would you compare this to seafoam?
Can this be used on traditional engines where the gas is sprayed in from behind the valve?
You should just go with a fuel system cleaner. This is meant specifically for GDI where the fuel isn't sprayed directly onto the valves but directly into the combustion chamber. Regular motors spray onto the valves thus cleaning while providing fuel.
What happens with all dirty on the valve, were is going?
Man's really had to give us a warning about not putting our hand near moving parts or hot parts like we are brainless. I swear in a previous video with seafoam you did the straw got caught on one of the pulley wheels for the accessorie belt and you just went right on trying to grab it 😂😂
does this also works with diesel engine + DPF ?
Any side effects (negative) after using, such as it hurting catalytic converter, O2 sensors or EGR valves?
Exactly what I thought. Too much Too fast can be a problem downstream. Be careful of sensors in the intake. I'm going to try using 1/2 the can on my Buick 3.6 and then very slowly. I'm mostly worried about the exhaust Valve getting stuff hung up Under the seat which will cause it to Burn.
Wonderful
I have been using STP products long before injection or GDI and all ways had good results. But keep testing. What about a presoak like over night or 24 hrs
Can you do this on a Audi Q5 too❓ or only domestic cars❓🤔
Is this ok to use with turbo engines?
At least you don't don't constantly press a spray button. And the ones in the container weren't even running in the engine and cold. 👍
I've used Seafoam and CRC as well.
Will this help clean piston tops too?
Great video. I have a 2018 Honda Civic that’s direct injection with turbo do you think this product will work for it?
It will work, the throttle body is tighter to get too though I am a tech at Honda and will say it’ll be way better to access one of the vacuum hoses on the intake manifold. Also because the throttle body’s on Honda’s don’t tend to Gum up all that bad.
@@GreyMK7Jet Thanks Have they got the oil dilution problem solved on the engines yet.
Honestly not a 100% fix but I highly recommend to not follow the minder percentage. It will sometimes carry past 5k miles between oil changes. If your running full synthetic oil cap at 5k miles and change oil anything between 4-5k it ideal I also have friends running 5W-30 synthetic and that’s shown to be most effective.
@@GreyMK7Jet Ok thanks again for the advice. I love the car but I want to last. I also have a 2012 civic ex it’s been awsome it got 20000 miles on it now still running strong.
Is it good in a old indirect injection diesel truck ?
Can you do this on a 2015 wrx safely?
You gotta love egr
