Hi everyone,

Is there any danger in using 1-2 quarts of diesel to flush the engine at my next scheduled oil change?

The diesel is purchased from a petrol station, and then poured into the crankcase. The engine is then run at idle for about 20 minutes.

I've done this before on an E30's engine. The engine ran better but then after doing this twice I began to notice white smoke coming out of the tailpipe. Now, it was a really old engine so it could be normal wear and tear but i don't know if the diesel flush procedure listed above contributed to this.

I understand that this can also be done with kerosene instead of diesel.

Anybody done this before? Please advise thanks !
