Oil recommendation 1977 cb550F2?

(1/3) > >>

JustcallmeMrT:
Hoping to give it its first kickover this weekend, read a lot of debate over mineral vs semi synthetic vs full synthetic, detergents added, no detergents, different viscosities... everybody and their dog seems to have different experiences.  Since I have no idea what the PO was using, anyone care to make a recommendation?

Bitsa (Ralph Wright - RIP):
Mr T
My view is these were designed for the oil at the time which is not synthetic.I use mineral and have no problems at all no clutch drag etc and the oil pressure on the gauge I have is well OK for me.
Cheers
Bitsa
PS Did use synthetic on a CB400/4 and the clutch dragged like a git when hot

hairygit:
Have to agree with Bitsa on that one, they were designed to use mineral oil, so don't waste money on synthetic, there is no real advantage to it, but it has been known to cause clutch slip and clutch drag. Bryan J will be able to tell you the exact grade to get from Tesco, believe it or not, it's a diesel oil! ???

Tesco, now that's unexpected!

Tesco 10w/40 mineral oil. I think it is at £16 for 4ltr. A bit over priced for me.
