OK I was just wondering if there is any products that are out there that flush you engine free of build upright before a oil change. My father said awhile back about use transmission fluid. I went into my local auto zone to ask if they had a idea of a specific product . One person told me that the trans fluid will not work but Dot 3 brake fluid will work while his co worker told me to use bleach.... Ok im not a idiot i know that bleach will be bad for your engine and i dont know what the brake fluid will do. So does anyone have any good products to try.

The people at that Auto Zone don't know what they're talking about. The best way to flush an engine's oiling system is with very frequent oil changes. I did this a long time ago on a 1965 Cutlass that hadn't had oil changes in several years, and by changing the oil weekly for about 6 weeks, I got all the sludge out, and there was a lot. |

I have heard transmission fluid will do it will help flush the engine and there are specialized products that might do a better job. Your mileage will vary on these products.
Bleach is the worse idea I have ever heard. Bleach is an oxidizer. It will corrode everything.
I don't know about brake fluid. It will absorb water but I don't know what other effects it will have.

Trans fluid will do the job cheaply and efficiently, but if you do decide to do it, only run a little at a time. An example would be to put in 2 quarts (addition to the oil that you already have and that's dirty) and drive 100 miles before an oil change, or change your oil with something like 10w40 and replace 3 of the normal 7.5 with trans fluid. You would only want to drive a max of 1000 miles or so when doing this and then go back to regular 10w30 or whatever you run.
If you have an oil burner the best thing i've found aside from tearing down your engine and cleaning your rings is to use GM top engine cleaner poured into the cylinders via the spark plug holes and allowing it to soak overnight.

But word of warning! Don't get your engine "flushed" at automotive centers or shops. If you a shop offers this service, do not continue your patronage there, as they are un-honest. An engine flush is quite worthless (keep in mind, flush is different from clean). Engine flushing could actually damage your engine, as it would actually trap gunk up at the rollers and stuff (whatever they are called). Your oil takes care of that for you and that is the reason to change it often.
Running a liquid through your engine in conjunction with the oil is fine, it cleans some parts of the engine. Like adding fuel additive to clean your injectors or fuel system (which I recommend everyone does at every oil change). But actually using pressurized fluid or air or whatever there might be will just be damaging and not really do much in the ways of "flushing your engine"
Just a word of warning...

Does the gunk motor flush really work? Im wanting to try it on a 95 with 130k miles. What about this restore stuff that I've heard about?

My mechanic has a Snap-On machine that flushes engines and cleans them out. It uses a chemical that was discovered in WWII being used on submarines for cleaning. I can't remember the whole story behind the product. But I bet that would be the best solution besides 10 oil changes, and probably cheaper!

tranny fluid is the fix. but like the brain said on the n* only use a little at a time. they already suffer from oiling problems as is.
but in the neon and fiero i drain the oil and run straight tranny fluid. i let them idle for about 30 minutes than drain and fill with oil. keeps my engines and turbo (neon) spotless internally

The tranny fluid was pretty black afterwards. (I suppose 20 years and 220,000 miles will do that.) |

I believe there's a higher level of detergents in transmission fluid than motor oil. That's why transmission fluid seems to work so well.

I didn't think to mention Auto-Rx, a product many of us (myself included) have used in the past. It's a long-term style engine cleaner, but still is advertised to remove sludge and build-up. The 7-page (and almost 4-year-old) discussion on Auto-Rx is located here. |
