Diesel & Oil

[tresl]

I have had some people tell me that they will add 1/2 Qt to a Qt of motor oil to there diesel every 4th time they fill up. They do this because they feel it will help keep the engine better lubricated. Has any else heard of such?

Yes I have heard of people doing that and I have done it to old trucks back in the 80's and it didn't hurt them. I wouldn't want to do it to one of the new PowerStrokes.

I remember reading something about actually having too much lubricity in your diesel fuel regarding the psd's. Can't remember where I read it at though Something about possibly gumming up the injectors and/or the filters

not to mention that the injectors, o rings, and such are not designed to run with motor oil or atf. you will take out rubber parts with all the detergents in the oils, and not to mention they might not be compatable with the oil itself.......Marc
