    "best"...that's opening up a can of worms

    But I like and use Valvoline VR1 Racing Synthetic in a 20/50
    Or, Brad Penn Grade-1 Racing Oil (dino)

    Now which weight depends on bearing clearances but a 20/50 should serve you well...just remember > ALWAYS bring oil TEMPS up before stomping the pedal

    Like Hammer said , a lot depends on a lot, we run 20/50 in most of what we build , we use Torco, Lucas and Valvoline , no much of anything thats readily available from an autoparts store excepting the Valvoline Tom

    this subject has been covered many, many times on here...do a search & see members opinions/choices ...i believe most use 10w/40 or 20w/50 of the brand they like best...i personally use Penn Grade 1 50w...just my .02 cents

    I'm more concerned about the weight. A buddy picked up a boat with a freshly built motor. Everything on the top end looks new. I don't know what the clearances are so thats why I'm asking.

    If the engine is flat tappet you must really pay attention to what additives are included.

    I've been running Joe Gibbs 15w-50 in my cars for a while with no issues. If you're running a flat tappet cam, you want lots of zinc in whatever you use.

    Check this out. This came from Performance Jet. I too am running a mild built 468, it sure got my attention....

    Engine oil alert 2010
    There is something going on in the automotive oil industry today that will effect all hot rodders , hot boaters and high performance engine enthusiasts. Performance Jet would like to bring this issue to your attention in the hope that you can avoid the costs of pre mature cam shaft failure on your jet boat engine.
    With today's engine oils we are seeing the reduction or complete elimination of Extreme Pressure oil additive packages (EP). This EP package is known as ZDDP or zinc dialkylidthiophospate. Basically this is a mix of Zinc and Phosphate. ZDDP has been an important additive to engine oils for over 70 years. It has an excellent track record at protecting the sliding metal to metal cam interface on your high performance engine.
    Why is this EP package being removed from engine oils? As part of an effort to reduce vehicle emissions the U.S. EPA offers vehicle manufacturers "credits " for early implementation , as well as penalties for violations of emission standards.
    By this year the EPA has called for the life of catalytic converters to reach 150,000 miles. The rub here is that the EP package of ZDDP is poison for catalytic converters so the manufacturers have pushed for the elimination of Zinc and Phosphorus from all motor oils. In the last ten years all motors are built with roller tappet cam shafts so this change does not effect the new generation of engine owners. Unfortunately, the folks with high performance flat tappet cam engines are left out in the cold. Without the EP package you run the risk of premature cam and lifter failure at break in or on normal high performance use.
    In the past, ZDDP has been added to oils in amounts resulting in approximately 0.15% Phosphorus and 0.18% Zinc. The film of the Zinc and Phosphorus compounds provides a sacrificial wear surface protecting the base metal of the cam and lifter from wear. According to the S.A.E. tech bulletin #770087, operation of a flat tappet engine without adequate EP additives quickly leads to lifter foot scuffing and cam lobe wear.

    So, Is there and oil that has the zinc/phosphate additives that will work in the marine world?

    I am curious as to this as well. I currently run Castrol GTX 10W/40 and add a ZINC supplement made by RISLONE. Looks like I may need to step up to 20W/50.
