Crate 5.4 2 valve installed- what oil should I run?
I ran Mobil I 5-30 high mileage on my old engine. Should I now switch to 5-20 or keep using 5-30 (just not high mileage formula)?

Thanks for any oil advice.

I would use the factory recommended Motorcraft 5w20 synthetic blend and a Motorcraft filter. First change at 2k, then every 5k.
