I would think you should be fine on Mobil 1 5w-30 or 10w-30.

ok for me what is a good regular oil to run in it then? i like castrol. what you think?

Mr. Luos · 02-21-2006, 07:30 PM

Castrol is good.

I use the red lable german Castrol 0w30 synthetic
Check it out at www.bobistheoilguy.com
Plenty of testing - they even have their oil analyzed for wear metals
check Patman's posts.
I been using it for over a year - no problems.

Also great oil if you can find it.
Full synthetic though 97cavalier.

I normally use Mobil 1 but I have used syntec in the past as well. I have a Corvette LT1 though and those got Mobil 1 from the factory and thats all that was recommended.

I have to agree with synthetics. If you have a car with low miles, ok run it if you want. But in the higher mileage engines, it might just be a waste. Personally I have a 350 in my car with high miles. Well 83,000 on a 78 is good but still high. I run 10-40 natural in the summer and 10-30 in the winter, I live in the cold climate so I do lower the viscosity for the winter to help in the cold start oil flow. It's a common practice here to use lower vis in the winter and higher vis in the summer. You also might want to run a natural oil with a synthetic additive to help in lubrication. I've used Lucas before with good results.
I have only used synthetics in one car. I used the castrol syntec in one of my "old" new cars with decent results. From what i hear now, royal purple is the front runner in synthetics, and amsoil is also a good alternative.

Mr.luos, did you say run synthetic?

Formyla · 02-24-2006, 05:15 PM

I have 59000 miles on the Bird. Been using synthetic after I broke it in. Started with Mobil one then went to Amsoil - about 9000 miles ago I went to GC 0w30.

Any synthetic is better than dino oil.

Nothing but Mobil 1 5w-30.

Started the Grand Am on it at 32,000 miles.
Trans Am has been getting it since 10,000 miles. Right now I am running cheap conventional oil for break-in, but I will switch back over to Mobil 1 in about 3,000 miles.

Use 5w-30w AmsOil.. You can't go wrong.. A little expensive but lasts for 25K miles without changing, all you have to do between that 25K is change the oil filter 2 or 3 times, depending on how you beat on it...

I would NEVER let ANY oil go past 5,000 miles. Even if it is proven to last that long.

Although I do agree....Amsoil is good stuff.
