i've always been into valvoline, but i got crap from a friend for it. what brands are you guys into.

from what i have heard penzzoil and quaker state are the same and they both suck? is this true?

so anyone know the facts on all this. i'm building a new engine and need to figure out what i'm gonna stick with.

 

Mobil 1 5w 30

 

Well... There's almost as many good oils as there are users, so be prepared for some varying answers.

So... My choice of oil is fully synthetic Mobil 1 10W30. I know it is not everybody's choice, but I've used it in all my F-bodies since 1999 and never had one single problem supposedly caused by oil.

I'd say as long as you use synthetic oil, you'll do just fine.

 

I use Valvoline in my Grand Prix and don't have any issues with it. In the Camaro, I am using 5W-30 Mobil 1 synthetic.

 

I'm useing Mobil 1 0W-40. I like it better that what i was useing (Mobil 1 5w-30).
Seems smoother and quieter.

As long as the oil meets the correct American Petroleum Institute (API) Service Category and has both the API Service Category and the ILSAC specifications criteria with the "Starburst" symbol on the bottle, I am good to go regardless of brand name.

 

I use Wolf's Head oil. It really slowed down the "smoking when you start it" problem in my 90 RS. When I had Valvoline in there, it was quite a bit worse. As far as Pennzoil/Quaker State/Wolf's Head oil being crap, I totally disagree. I know several people that have used these brands and never had any problems, even with high miles. Like the above post, people make it a much bigger deal than it really is. As long as it meets the latest API specs (SL or SM), you can bet it will be just fine with proper changes. Just my opinion.

 

I agree completely, and would add that the owner's manual be strictly observed.

 

Mobil 1 5W-30 for me

 

I've been using Mobil 10w-30. I think it's a bit thicker then 5w-30 but it really isn't cold over here so it should be fine. The reason why I went with 10w-30 is Costco only had that .

 

10W30 is fine in warm climates.

 

so all you guys are into the synthetic??? er... that stuff gets costly

 

You can get a 5 quart jug of Mobil 1 full synthetic at wal-mart for ~$20. That's just like getting one quart for free from auto zone or advanced. I'd say that's not too far off from dino oil either, and well worth it.
