I love to find out things about motor oil and found this Web site! Synlube advertises that it`s oil is not fot RX`s but there is sure a lot of stuff on this site that is super interesting. Sure changed the way that I look at "dirt" in motor oil!! www.synlube.com

We all know that we cvhange oil, not because of dirt, but because of fuel delution problems with rotories. Sence the majior thing the oil does in our engines {other than lubricate the apex seals} is lubricate the crankshaft, no real dirt gets into these engines! That`s why the oil is still almost clean when we drain it!!!
Check this out!!!
