My current oil fill with out any oil additives is Quaker State Defy 10-w30.
for my next oil run with the moly ep, i have available on the shelf: a jug of valvoline maxlife high mileage synthetic blend in 5w-30 and also a jug of valvoline full synthetic high mileage in 10w-30.
I don't have any lc-20 which if i recall from an old thread is mr mola's recommendation to run with the moly ep, so questions:
which oil to use of the two above that will play well with the moly ep? and
how much moly ep only 4oz, 8 oz or the whole pint bottle?
thanks
I'd probably add a half bottle to the Maxlife HM 5W30. It will thicken the oil up a bit. A whole bottle during the winter, I wouldn't be comfortable doing that. OTOH 4 ounces probably won't do anything at all.
