Are all HM oils syn blend?
Are there any HM oils that's easily found which are NOT a syn blend? As in conventional.
I am not 100% sure but is Pennzoil a "conventional" HM oil?
EDIT: NOPE. Looks like it's also a syn blend !!! So are there NO conventional HM oils at all?
Valvoline ML, Castrol GTX, Mobil 1 HM, QS HM ... they all seem to be syn blend.
I am specifically interested in the 5/20 and 5/30 varieties.
