<VV> AR 15 Motor Oil

[Joel McGregor]

I would challenge someone to have their used oil checked.  I would bet that
any conventional oil is pretty well shot by the 3000 mile mark.  An air
cooled engine is obviously harder on it's oil than water pumpers are and a
turbo even more so.  I change my Mobil1 at around 3000 miles but I don't
worry too much if I go over.  It is nice and black by then and much thinner
than when fresh.  I change my transmission oil at the same time - manual and
automatic.  My Corvair boxes shift noticeably better when I change the lube.
That tells me that they need it.
