Title: Which oil
Post by: oldtuggie on May 04, 2020, 04:04:47 PM: Hi
CB 550 four just finishing a full engine rebuild, which oil should I use.
Mineral , semi synthetic or fully synthetic.
I have read that fully synthetic damages the clutch ?

After. The most you need is semi synthetic

Just checked 15w40 is cheaper

Post by: Bryanj on May 04, 2020, 10:17:07 PM: That says running in oil so dont know if i would trust it full time but just putting 10w40 mineral engine oil into google brings up loads, do read specs as some synthetics sneak in!

Post by: Bryanj on May 05, 2020, 09:12:34 PM: All motorfactors SHOULD stock mineral oil, just dont tell them its for a motorcycle as a lot get twitchy about selling the wrong thing and getting sued.

Not talking halfrauds here but proper motor factors
