Oil Reccommendation
 

I'm sure this is probably a common question but here it goes.

I'm about to do my first oil change since I bought the car. Who ever had the car first wrote down when they did the first three oil changes but then got lazy. The first two are castrol synthetic and the third one is mobil 1. I'm pretty sure when I bought the car the guy had said he was using mobil 1 synthetic.

I was looking to use mobil 1 synthetic now when I do my first oil change, it should be ok right?

I'm just thinking worst case scenario they started with synthetic and got lazy and stopped (which I doubt) would it be bad to go back to synthetic?

Oh and I geuss I should use 5w-30 right?

Oh and I geuss it takes about 5 quarts?

And what brand oil filter should I use?

Mobil 1 5-30 will be fine.

There are lots of opinions on oil & filters. Most end up pointing to Wix, Napa (made by wix) and the K&N filters, at least for gen 1 SBC. But I never had an issue with a Delco/GM or a Fram.

Mobil 1 FTW. Buy it at Walmart - it's half the cost of buying it at a Mobil/Lukoil station....

I use Mobil 1, too, w/ K&N oil filters. I get the M1 at Costco.

Yeah, it is like $23 a case of 6 qts at Sams Club. I wish they'd carry the heavier stuff too.

Wish I read this before I gave autozone my money lol.

I ended up just doing Mobil 1 synthetic 5W-30 with an STP Filter

Thanks for the input though, next time I'll be at Wal-Mart

the ls1s seem to like the german weight of mobil 1 (0w40). i dont know how different lt1s are though

i just did an oil change today...5 quarts of mobil 1 5w30 and a delco filter...have never used anything else since i got the car...

10w30 here...

I put M1 15w-50 in the beater.....

- Justin

eltea's get great results with this too, i use it when i can find it with a k&n 3002 filter...go

I bounce from Mobil 1 5w30, German Castrol 0w30 and right now I'm running Amsoil European 5w30

I use Royal Purple XPR 5W30

I run M1 10w-30 in my Jeep 8)

You'll be fine running 5w-30 in your car nick.
