Boosted S550 oil?

[NightRide]

Have a roush supercharger setup on mine but no mention of changing oil weights. What are you guys using on boosted setups, still 5w20?

M1 5w30. Not a fan of factory thin oil recommendations for fuel economy on heavily modded cars.

I used 10w30 amsoil in the shelby with good results. Recommended was 5w50 just seems weird ford would use 5w20 in a boosted coyote. They either want the thinest oil or the thickest. 5w30 would make things easy since that's what my superduty takes.

I prefer a good 40w oil in an application that it likely to see a lot of bearing load.
