Hi Gentlemen, Recently purchase can of GM Top Cleaner 10-3015 32 OZ can. Read good bit of posts of various forums that this stuff is the ultimate cleaner. Read a few different ways on how to use it. Placing 2Oz in spark plug holes. Going throught pcv tube and letting it soak overnight. Any tips from on how to use it or how much to use Thanks.

 

I use a fuel induction drip applicator with a valve to control to a slow drip. DIY, Start up and use any object for a pedal depressor between the seat and accelerator pedal to maintain 1000rpm over idle. Then walk away and check back in a half hour or so. When empty, shut engine off, disconnect and let hot soak 10 minutes, then drive it like you stole it.

 

Thx 4 follow up. Going to run it through this weekend. Ill let you know how it comes out.

 

Whats the max onces you have ever run into the throttle body?

 

Update, First treatment I out 8 ounces into the drip can. Went for a drive after 50 minutes like I stole it haha, The acceleration was smoother and the engine much quieter at low rpm and even at 75 mph. Its designed for motorxycles but works perfectly in the evap valve above the trottle body. I did a second treatment of 12 onces. Letting it sit overnight. Will give you update 2mrw. Here is the drip I used on amazon.
