I just ordered Amsoil Series 2000 SAE 20W-50 Synthetic Racing Oil. They say that you can extend 3x manufacturer's recommended intervals, although right now I'd never do that, no technical reason just uncomfortable. I talked to their technical dept, told them it was for a 930, mentioned the air/oil cooled engine and turbo as opposed to water cooled, and it did not seem to matter. I'd really like to know how they base their intervals...I'll get it analyzed after 3k and possibly go 5k.

1986 930
Gone:71,2,4 914's, 70T, 71T(RS),77S
