Which oil seems to stand out?

[FISH 99 WS6]

Getting my car out of storage soon. There are some new synthetics out now and I was just wondering which is the oil of choice. I use Mobil 1 5w20 or 30, can't even remember, and just curious if there's something better now. Only put about 2k miles/yr if that matters.

Check out the "Oil??????????" thread under the Firebird/WS6 tab.

I've mentioned this a few times but check with "Sarge" his thread "oil junkie" is full of data to read about oils. He has actual test data on various types. He's got like 25 years in studying oils and testing. In my oppy he's the best there is on hard data.

Lots of oils out there better than Mobil 1. German Castrol, Castrol "new edge", Penzoil Platinum. These are just the off the shelf ones...

Penzoil Platinum was the one that I was curious about. Thanks for all the advice. Got some research to do.

Pennzoil Platinum is better than Mobile 1? whoa where have I been....last I heard(havent really done much research on oil in months) pennzoil was akin to quaker state which oxidized easier and broke down faster. interesting

Yes it is.

[ls1fan74]

i always thought pennzoil wasnt that good of a brand up until reading the oil junkie forum. Now that is what ive been using is pennzoil platinum.

The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engine oil’s ability to resist heat and oxygen breakdown when contaminated with oxidized/nitrated fuel, water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine.

AMSOIL 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum protection and oil changes are reduced, saving time and money.

Mobil 1 has reportedly failed the ASTM Test Sequence IVA, which is part of the API-ILSAC testing protocol. Until Mobil 1 addressed this claim, I’d be a little hesitant of putting it in my car.

So if I go with Amsoil or whatever, should I stick with the 5w20 or go to 10w30?

[INMY01TA]

why are you using a 20 weight to begin with?

[FISH 99 WS6]

Guessed wrong. Went out and checked, 5w30.

This is what my information shows for your car:

1999 PONTIAC FIREBIRD 5.7L 8-cyl Engine Code [G]

SAE 5W-30 is preferred.

All Temps......5W-30

Amsoil 0-30 is going in my Trans Am next change.


Daily driver (2001 Grand Am GT with 100K miles) gets 10w-30 Pennzoil Platinum.
