Stp Pro Series Intake Valve Cleaner works!

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.

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.

[@RipPhillips]

@@jeremyr7147 just curious if you've serviced 2.0 T VW engined for valves mainly with this?

[@jeremyr7147]

@@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.

[@RipPhillips]

@@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.

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

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.

Is this compatible with a older truck 1990 Ford 150 4.9 litter

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.

Impressive results. Try their new ceramic oil additives, they have 2 different ones
