The ams oil also does not need changing for up to 25K miles and not that goes the same for the oil filters. Seems the oil gives extreme protection against friction and therefore does not need to filter particles if there aren't any. I'm going to use the 15-40 100% synthetic in my Roadster srt when she is broken in at around 5K miles.
vege oil heh? sounds like its nothing more than Castor oil.
