I just had to contribute...

Back when I was a "kid", my old man used to flush his engine with Diesel probably every 25,000 miles. He was an aircraft mechanic, so I guess he new a few things. It cost a bit in oil, but he swore by it, and the 1972 Dodge Dart (225 slant 6) that he bought new & was his pride & joy went almost 300,000 miles on an untouched engine.

He would drain the oil, replace with diesel, start the engine & run for maybe 15 seconds, then let it sit for a while, drain the diesel, put oil in, let engine run for a while, change out the oil & move on.

I always thought it was strange, but he said that diesel actually has reasonable lubricating qualities at low temperature & no load.

Honest, this really happened, I remember standing in the garage watching him run his pride & joy with diesel as a lubricant just waiting for the engine to seize. I was into repairing lawn mower engines at that phase in my life (ah, good old briggs & stratton motors :-) ) and knew all about pistons, cylinders, crank shafts, connecting rods, valves, etc.

I personally run an engine on diesel, but what's to stop a good old "flush" with diesel?? Any mechanics have a comment on this QUESTIONABLE technique??

Cheers, Steve Williams
