What engine oil to put in my SBF

Engine oil is always a hot button topic. Lot's of myths, lots of experiance, and very little science. So, here's my opinion.

I use a pure synthetic. Not so much for the longevity, because I change it 2-3 times a year. But because of it's high heat capacity. A true synthetic can easily handle 240* without break down. I like that. Some days on the track that oil gets pretty hot, despite the cooler.

A true synthetic starts with a PAO base stock, no dino oil. Mobile 1 is NOT a true synthetic. it's not a bad oil, but not a synthetic.

If it were my engine, this is what I'd use: http://www.summitracing.com/parts/RPO-01250/
