Engine oil

[SeattleRod]

Has anybody used this oil?
If not, what do you recommend?

I used to run a special "oil for wet clutch" in my dirt bikes but, I rode dirt bikes a hell of a lot harder then I do street bikes and obviously, I rode them in the dirt, not on the relatively clean street. Never tried that brand though and don't remember what I did use.

I run the same Valvoline 10w-40 in my CB750 that I use in my car and truck. It costs less and you can get it almost anywhere.

My clutch has been on it's last mm since I got this bike several years go and it is still hanging on, given that I only ride it a few hundred miles a year these days but it has done duty as my daily driver more then once. If I try to drop it, it will slip, but if I wait until it's fully engaged, I can twist on the throttle as fast as I want.

The most important thing in any internal combustion engine is keeping the oil clean and bikes need it changed more often then cars as your clutch and transmission are using the same oil as the crankcase. (At least in bikes this forum is focused on)

It's m/c specific oil and likely has zinc in it by the JASO spec there. Car oils no longer have zinc and the friction modifiers they replaced it with can actually be TOO slick to make the starter clutches sometimes slip. The zinc stuff won't have that issue. The zinc is why the cost may be high, motorcycles got by the EPA no zinc spec due to fewer numbers on the road but you pay an emission penalty for it.

I would say it should work great.

Been running valvoline motorcycle oil in my street cb750 motor, found that Amsoil caused the starter clutch to slip. I run Amsoil in everything else, dirt bikes, cbr's, my drag race cb750 motors that I dont have to rely on the starter clutch. Like said the lucas more then likely wont affect the clutch but more then likely will affect the starter clutch if it is close to not working. Could try it and if problems arise switch back to a mineral based motorcycle oil.

Thank you fellas for your replies. The first 500 miles after the rebuilt I used Valvoline max life but I wanted to try a motorcycle specific oil this time.
The Lucas oil is definitely more expensive than generic oil and I’m planning on changing the oil every 1000 miles, it if it’s good for engine and the clutch, I think it’ll be worthwhile.

Thanks again for your input.
