    Best Oil For High BHP Z20LEH

    What oil is good for a high bhp LEH engine?

    I don't want to run GM oil as I want the best really to make sure the engines getting looked after.

    I was thinking about mobil 1 but unsure of what grade to run.

    I'm running a garret so I doubt i will have to worry about the oil getting past the seals.

    Fully synthetic need only apply

    Thanks
    Lee

    Well vauxhall use 10/40 semi and 5/30 fully synth so i would say you could use the 5/30 aswell.
