I second Tom's suggestion for ATF. I've used it for 30 years. ATF is
basically high (VERY high) detergent 10wt oil with special additives for use
in transmissions. The additives have no effect when used in SU's. However I
would not mix type F with Mercon. They are not compatible. I really don't
know what effect (if any) it would have but I don't intend to find out. I've
always used type F for no particular reason than it is what I started using
originally. Mercon will do just as well. I have heard a number of
discussions about which oil to use but for street use it really doesn't
matter. I've tried everything from 5wt to 30wt and it didn't matter. I would
not suggest heavy oil in cold weather. Even 20wt gets a bit sluggish in the
cold. ATF has never given me a problem even in sub-zero temperatures plus it
is readily available.
The purpose of the oil is to keep the pistons from opening to quickly upon
acceleration and leaning out the mixture. Different springs will have a big
impact on their operation. The oil is only use to dampen them slightly.

Hi Everybody,
Forgive the novice but I really don't know.
1) I read on one of the SU carb web sights that the recommended oil for the
SU
oil damper is 20 weight. I went to the Auto Store no 20 Weight. Where do
you
get this oil is it called something different?
2) I will be getting body work and a paint job done early next year. The
guy
doing it said I could save some hours by taking the outer trim work off
myself
instead of him doing it a $50.00 an hour. How does the hood scoop chrome
piece come off?
3) Any hints or suggestions that might help as I take of the chrome would
also be appreciated.
