Hi, finally have a question search didn't fully answer.
Recent oil analysis (22ppm potassium at 46k on oil) indicates a possible small intrusion of coolant into my engine oil. From a few posts here and elsewhere, it was suggested that EG damaged bearings at less than .4% by volume, but PG did not at up to 8%. I can find no substantiated proof of this. Besides searching, I have talked with Blackstone, Fleetguard, and Fleetguards oil analysis tech. None of them had any info that one was less damaging than the other.
If I were sure, then I would switch to PG as a precaution, but hate to waste good coolant if no advantage. Anyone have any input on this? Preferably with some studies or sources I could refer to.
Thanks
Don
