Just wondering what type of oil you guys would recommend using with a 135K 96' motor, stock bottom end, LT4 kit, intake, tunned..

 

Mobil 1.

 

10w30.. or what ??? btw im located on the georgia coast.. winter feels like summer and summer feels like hell..

 

SYTHETIC Mobil 1, 10w-30 "extended performance"
every 2500 miles for me.

 

Damn, you know that stuff can go 15,000 miles before an oil change right. I would never go 15,000 but even 6,000 would save you about $50 every oil change.

I use Mobil 1 0w-40 right now, but would like to switch to German Castrol 0w-30 if I can find someone who carries it. I hear the German Castrol is the best for LT1's. The oil I'm using now is probably the second best oil next to the GC.

 

The GERMAN Castrol only comes in 0w-30

 

Yeah, thats what i meant.

 

Hotlanta - Mobil 1/10w30....

 

Amsoil 0w30, the best there is.

 

I was going to put in Valvoline Max Life (or whatever it is) 20W50

Aren't you supposed to put in a heavier weight in higher mileage engines to prevent leaks from synthetics and the lower weight oils

At least thats what the autozone guy told me

 

I like to dump the Mobil 1 synthetic in mine as well. Its not cheap, but still cheaper then 5 quarts of Royal Purple.

 

Autozone is the only place I know of that has the German Castrol.

 

Might I suggest you edit the question to ask "and why" because you are getting info not backed up by fact. I am not saying they are not posting the facts I am saying with certainty that several of these guys have ZERO data on which to backup their choices validity.
From what I am reading LT1 Power, porksoda and moparman have done some research, the others seem to be more likely relying on marketing.

 

I run Red Line 10w30 in Winter and 20w50 in summer.
Typically I change it at 10 to 12,000 miles.
I change the filter every 5 to 6000 miles, but 90% of my 120mile round trip to work each day is freeway at steady speed.
Not cheap at $8/qt., but I see it as cheap engine insurance.

 

Go read on this forums there:

For a lt1 the 3 best choice base on oil analysis are:

-Castrol German synthec 0w30
-Amsoil European synthec 5w40
-Mobil 1 synthec 0w40

Since in Canada im unable to find some castrol, i use the amsoil one.
