What Brand Oil's Are You Using
 

Im curious im running mobil 1 5w30 syn, mobil 1 syn atf, and mobil 1 syn 75w90. Im thinking of switching over to royal purple in everything. Just curious what brands and weight oils your running. Thanks

bolt on car-111k miles
Mobil 1 0W40, cheapest tranny fluid available, whatever came in the rearend from the factory.
50+ psi oil pressure @ 2400 rpm highway cruising speed but not too high on cold start

mobil 1 0W40...383 stroker

Amsoil 5w40 in the engine, Torco ATF in the transmission, and currently Mobil 1 in the rear. My new Strange 12-bolt will have Torco RGO when it gets installed.

royal purple oils here.

Amsoil all around.

I think im gonna switch to royal purple in everything this winter. 0w40 just sounds scary but ive heard only good about it. Anyone had any problems wiht any oil brands?

Meent how are the torco oils?

German Castrol 0W-30, best oil analysis I have gotten is from this oil.

castrol syntec 5w-40 for the engine and castrol atf dex 3 for the tranny!!

castrol syntec 10w30, but next time royal purple.

Amsoil Here

Engine: Royal Purple 5w30 (before Mobil 1)
Tranny: Royal Purple Synchromax 10W
Rear End: Redline Heavy ShockProof Gear Oil 75W90

castrol syntec 10w30

royal purple 10w 30-engine. rp--?(forget exact weight/name) in the rear, and got rp syncromesh waiting to go in the t56 next time i have the shifter out. couldnt be happier with the switch from previous m1.

A secret and magical blend of herbs and spices! (imported from Germany by Castrol.)

haha, ditto on that...I guess... :)

Oh...and in the T56 I run Valvoline Dexron III/Mercon dino and in the rear 85/140 RP w/the GM addative too (I have a Torsen, so it wont "slip too much" or anything)

Engine: M1 0W40
Trans: Valvoline DexIII (dino)
Rear: GM/Goodwrench 80W90 (dino) + GM additive

No complaints with any, no plans to try anything different.

Valvoline everywhere.
Syntech in the motor of coarse :)

Castrol 0w 30 in the engine and castrol for all other fluids except dexcool in the cooling system.
