Re: Which oil should I use?

Older engines with low specific output do not need zinc in the motor oil.



Some engines built in the mid to late 1950s can benefit from it, and high output engines of the 1960s and early 1970s need it, if they are run hard.

Gnerally speaking, fuel additives are not needed when using today's pump gasoline. It's already loaded with additives. Just make sure it's fresh and of good quality. Most all flathead engines will run fine on 87 octane fuel, or lower.
