Which one?
Hi. I have a '76 Honda CB400F.
The one oil you should avoid is regular car oil because it contains "friction modifiers" that increase gas mileage (Noticed by the "Starburst" symbol on the bottle I believe). In a motorcycle though, you can't use these oils because of slippage of the clutch with the unit construction (Motor and clutch are lubed by same oil.)
There are several motorcyle oils out there, but personally, I run Chevron Delo 400 15w-40.
Before, I ran Valvoline motorcycle 10w-40. Did fine, but I'd like something a little better...
Once again, in my opinon, definitely do not go with a straight weight, and go with a 15w-40 "fleet" oil.
