What oil is in your sump?

[sparkplug]

Currently I have Mobil 1 0w30 and a AC Delco PF52 filter.

[robertisaar]

Meijer conventional 5W-30 with a quart of Pennzoil 10W-30 mixed in.

Purolator PL24011 (or whatever the number is for the PF52 sized Pure1).

mobil 1 15w50 in the GP, and some shell 5w30 in the wagon. I am liking the thick oil for the 3.4 DOHC so far but I can't really get on it because the alt is crapping out fast. PF52 all around for my 60V6s.

Would you recommend a 40 weight in a LA1 in the summer? I have a 5 gallon pail of Delo 15w40 for the lawn mowers that isn't getting used too quick.

Redline 5W30 in all my vehicles with 12,000 kilometer oil changes. The Toyata uses the stock filter but in Delco brand and my trucks use a PF2C Delco on Canton remote filter systems.

Mystic semi-synthetic 5w-40 with remote filter.

i got 4 cases of royal purple for free back when royal purple had that drive thing for you to show your car off in. didn't even know i won the contest (which was for $500 worth of royal purple stuff).

the GA get's the 5w30 royal purple and the subaru get's castrol 5w30... pf52 on the GA and stock size for the subaru.

I always use Valvoline. Most of my vehicles get straight 30 weight but my Celebrity VR is going to get 40 weight of some kind due to high mileage & a flickering oil light @ hot idle.
