3800 Using GM Top Cleaner

[J.E.T.]

I've read the directions on usage on ClubGP. What I dont understand is why an oil change is required ? Its not like the stuff touches - reaches the oil pan ?

And what affects will will have on the catalytic converter? With all that grime coming out, wont it clog up the pores in the cat? I'll be using the stuff before my new cat gets put on. Just wondering if anyone has ever pondered these thoughts.

Can you elaborate a little more on "GM TOP CLEANER". I may be having a brain fart but what is it?

I have done this to my car and not sure what you are talking about.

This stuff is the real thing for cleaning out your injectors....not the crap you pour in you tank. It is delivered via the frt fuel rail with the gas pump fuse taken out. Mix it about 75 percent gas, 25 top end cleaner in a contiainer designed to do this injector cleaning service. This container is hooked up to an air compressor also. Most shops charge around 80-1225 dollars for the procedure

The bottle will be gone in about 4 minutes. Run the car via the throttle body cable through all the RPM ranges too.

All the Instructors at Morraine Valley Community College use it/ teach it. Even the one head guy their who is ASE cartified Master Mechanic and writes responses to auto questions for the southtown.....I forgot his name....sorry...


How much grime do you think will come out? I dont think it is that much. A lot of peoplel in my class used this stuff on thier injectors and were amazed at the results........but, most of these people really dont maintain their cars that well, so it had more of an impact on them then my car.

Hmmm, we might be taking about different cleaners? The Top Engine Clean GM part # is 1050002. It comes in both spray can and bottle form. Most people just take the bottle and suck it down through a vacuum line while keeping the engine running. Afterwards, let the engine sit for a few minutes and restart. (Cliff Note directions)

All of the people that have used the Top Engine Cleaner are amazed at all the smoke it produces during the process.

My question is - why is an oil change needed afterwards? The stuff must get in the oil somehow? Not important I guess... Just do it!

It's a detergent. It cleans carbon, therefore it breaks down petroleum. The oil film that normally protects your cylinder walls will break up during cleaning and allow contanimants to leak past the rings. After any "good" top end cleaner (even fuel additives) it's good practice to change the oil. After cleaning, your oil will smell like gasoiline. Gas in your oil will also lower it's viscosity.

I hear ya. I use that stuff every once in a while at my (VW) store. I love how the smoke belches out like a bitch. Have you ever tried it in a shot glass with a beer chaser? Good stuff!

Is the beer and chaser for the car or...

I used the stuff a few nights back. It's perfect to perform this at night and when its cold. When you drive out with all the smoke behind you, your car blends right in traffic because all the other cars have smoking tail pipes! Heheheh.

How exactly are you doing this?

WE did it in the shop. No need to drive it around.

We feed the cleaner through the frt fuel rain nipple with the gas pump fuse pulled.

ran it through the rpms....4 minutes...done.
