bumpstop325 0 Report post Posted September 13, 2009 At my work they are changing there aircraft fleet to a multi grade oil. So i was able to get my hands on some unused left over AD100 SAE50 oil. Before I do my next car oil change, I was thinking of running some AD100 in my M30 for about 1000kms (my trip up to tga and back this weekend) then changing it over to some fresh ELF15w40. The reason for using it is to clean out the oil channels etc.. cause it has cleaning additives in it. Im just worried about the possibility of the oil eating at the seals. Its a straight 50 weight, so the engine will need a warm up before any use. Castrol AD100 extra info anybody think this is a bad idea? Quote Share this post Link to post Share on other sites
