Engine cleaning method...
Haven't seen this mentioned on this site;
Anyone ever hear of draining a quart of oil out of your engine, then replacing with a quart of ATF, running 500 miles or so, then changing oil? It is said that the Awesome cleansing properties of ATF are great for cleaning out an engine. I know a BMW mech. That swears by this. Comments...

No, this has been disproven time and time again. It doesn't do anything.

It will clean the engine because ATF generally has higher detergents than motor oil IIRC. But I would not do it. It might damage the engine.
The better question is what end are you trying to achieve? What's wrong with your car? |

Use only Synthetic motor oil in your engine. Anything apart from that will either do nothing or shorten the life on the engine

Ya that sounds like it's got bad news written all over it. There is a reason why we have different oils for engines and tranny's.

It was mentioned as a preventative measure for cleaning carbon deposits etc... Like a sea foam type of thing. Just thought I'd blow it by the group here as I've never seen it discussed.
