Anyone have opinions on oil brands for these motors for best lifter longevity. I have heard Delo heavy duty or Rottella. Need answers before dyno tomorrow. Havn't filled the pans yet.

The newest thing I been hearing is the rotella no longer has the plus 2% zddp in it either,sounds like a pia but the joe gibbs racing oil is supposed to have it BUT typically racing oil isn't formulated to run for 25 or 50 hours. GM E.O.S is still a sure thing though if you want to add some to a high quality off the shelf oil,Smitty

Heard allot of guys using the diesel oil because it still has suffer in them , something like that?

I have always just use straight 30 weight for breakin. I looked at my ecm after dynoing .all day making pulls was only 14 minutes of run time total.

Thanks guys. That is what I was hearing also. Just wanted to make sure I wasn't the only on hearing it.

Hoping to have good luck with these tomorrow.

thats what I was thinking of , Zinc

Rottella I think has it

I believe the Valvoline "Off Road" Racing oil has it too.

Is there a diff between the say 40wt raceing oil and the offroad racing oil????

make sure you video and post the results of the Dyno

Not sure....

My guess would be the amounts of Zinc because the VR1 is approved for the road and the Off Road doesn't need to meet the emissions standards.

I think the off road also has less detergents.
