Purestock engine oil weights?

What weights of oil is everybody running in their purestockers? I run 10w30 Brad Penn in my 360 Duster and wondered if that is the norm.

Valvolinel 20W50 VR1 in the big blocks.

I use Valvoline VR1 10W-30

 

Re: Purestock egine oil weights?

Castrol 10w-30 with ZDP Plus.

I went from 15-50 Mobil 1 (back before the extended preformance) to 10w-30 and picked up almost a tenth.

10W-30 VR-1 also. Available at my local parts store.

 

I use whatever is on sale at the gas station.o No:

 

Wesson :laugh:

 

Joe Gibbs 10W30 .

 

The way Tim Clary hot laps the Cutlass, I am sure he runs this:

 

Blue car gets Brad Penn with sausage and eggs in it, just incase it gets hungry!!!o No:

No kidden on rhondas, we pulled over 500 slips out of the box!!!!! was just getting broke in! hahaha

 

You forgot about the paint strainer part.
That got the big chunks of egg and bacon out.

I've been using Royal Purple 10W-30.

 

Actually, that was a coffee filter:Smarty:

 

I used 15-40 in the new engine for the new 68 1/2 Mustang coupe breaking it in on the dyno.I wonder if I could pick up a little HP switching to something different now.

 

Brad Penn
Straight 30 for break in
Blue car 20w 50
Green 10w 40

 

Along these lines of oil.

My neighbor just lost a cam lobe on his low mileage 79 z28. Is it possible to loose cam lobes even well after break in? Is the only insurance brad penn and zddp?

 

^ What he said. I have a case of Brad Penn break in oil, figured I will run it for initial break in. Dump it after cam break in is done, then refill with Brad Penn for the first 800-ish miles. After that... not sure what to use.

 

Happened to my 340 three years after the rebuild. Removing zinc wreaked havoc with flat tappet engines.

 

I just found a Brad Prenn distributor close to me so I'm going to bring a few cases of 10w30 with me to Stanton if anybody is interested in getting some.
