I have a 24 valve cummins and have added a PTFE resin base additive to it, with no problems. PTFE was originaly developed by NASA to use in the space program.
It has been in the diesel engine I have now since the first oil change. It presently has 64,000 +.
I will add it again the next oil change too,with no worrys about doing it again. Actually some of the proudcers of PTFE oil additives make one for large diesel engines. I put 1.5 quarts to a cummins inline 6 in a pick-up due to the amount of oil they take over a gasoline engine.
Also I have run it in gas engines with no problems either.
