Mystik 15w50 JT-8 in Sportster

[ppd1107]

I have a couple of gallons of this oil for my Jeep. Would it be a good choice for my 2005 XL 1200 C? The manual calls for either 20w50 or 15w40 both CJ-4 rated. The Mystik is CJ-4 rated but not exactly the called for viscosity.

Well Harley calls for 20/50 for most temps,and 10/40 wt under 40f, so use what fits.,,

I did a VOA a couple of years ago on Mystic 15w50 as a possible motorcycle oil. The results were very plain jane..nothing special. I passed. It would be OK for a Jeep, not on a machine you really like.
