1963 Superhawk Oil Weight

[Car Show Team]

Hi everyone, you guys have been extremely helpful and I appreciate it. I'm finally getting the Hawk back together. I'm wondering what recommendations anyone has as to what oil to run in it. Brand and weight. Any proven success stories? It's got about 4k on the speedo. Thank you very much, dave

I wrote this a couple years ago and will gladly share it again:
The last time some one asked this it ended up in a 50 some page train wreck of a thread.
Look at the casing near the engine number and you will see that the manufacture calls for 30W non detergent oil.
You can also use a blended more modern oil formulated for the wet clutch with good success.
Some here would argue that the detergents of modern oils "MAY" suspend the particles not allowing the oil spinner to work properly. To offset that concern; why not change oil more frequently?
IMHO, either oil will work well as they are designed to do. The bottom line is that you get to decide for yourself which is best for you. Rusty

Thanks much Rusty, I went with a straight 30 and so far so good. Thanks for the advice, I appreciate it.

Please remember that the notation "energy conserving" describes oil that must not be used in motorcycles with wet clutches, because such oil contains additives that make our clutches slip.

Thank you all again...

REMEMBER that stamp on the case was from year 1958.. or earlier.. back from the Benly days. Owner manuals say different.
