My friend has a 8.1 V8. What oil has showed the best results for the 8.1?

It does burn a little, Which I think is normal?
 
I would think that 0w30 would be a little thin...but your the oilgeek! haha!

Dont really have a recommendation, but my uncle used to run Mobil1 10w30 in his.

That is a common misconception, the 0w-30 is not really much different than the 5w-30 at operating temperature. The whole idea of multi grade oils is that is performs across a broad spectrum of conditions, the real difference is on cold starts, and when you are comparing 5w and 0w we're talking COLD.
 
I've run 10w-30 Valvoline, 10w-30 castrol, 15w-40 rotella... all good at 80K

The 8.1 is famous for oil consumption, most of it oil vapors because of the heat, full synthetic helps ,along with a 180* thermostat.
I'm installing a 160 thermo along with EFI Live.... Let's see what the BB can do
 
I always ran 10W30 Valvoline in mine but it used about 1qt per 1500 miles from new.
