Re: Mobil 1 oil
 

I just removed a customers engine 350 SBc 255hp from the dyno. We broke it in on Joe Gibbs BR oil. After 10 pulls (he had a few problems especially with the Quadrajet) he changed the oil to Schaeffer oil(rep lives near here) and we saw a couple problems with aeration. Customers engine so I did not get to play. He was a little upset but dont know what he will do, but he picked engine up this morning. Just another input

Re: Mobil 1 oil
 

It appears that the “Mobil 1” part of the discussion in this thread (its veered off course a few times) has been centered around Mobil 1 “Street” oil. Does anyone have any experience with Mobil 1’s “Racing” oil?

I currently use Mobil 1 Extended Performance 10W-30, in a sbf. Apart to freshen a few times, but I keep throwin’ the bearings back in it. Like out of the box, not a mark on ‘em – 275 passes.

Go back in this tread and find the link to the Mobil One site and you see the mix o their oils the race blends have what you need.
