I was told by my turbo guy to run either VR1 oil or Joe Gibbs. I am thinking about trying out the Joe Gibbs LS30. My machinist recommends the Joe Gibbs stuff. You just don't hear a lot about it.

I used to think the same way, this will make you think otherwise.

For those of you running 20/50, what are your rod and main clearances at and what is your oil pressure at start up idle and at hot idle? Hot WOT?

I've used Brad Penn 10w-30 with good results, but maybe 20-50 would offer some better oil pressure during hot idle and WOT? I know my Napa has the 10-30 and 20-50 for the same price.

im not turbo, but still boosted. VR1- 20/50 synthetic. You can catch it on sale for 4.99 some days. Get the case. Change it every 500 miles.
