What oil do you use

just wanting to know whats the most used oils in the XJ's ive been using valvaline motorcycle oil for 2 years 10w-40 and now im having starter clutch problems when its cold (first start of the day) the starter clutch doent seem to act up as much but when its hot it acts up alot just wanted to know if you guys think a heavier oil would help ?

 

I have used that oil. I also use Castrol motorcycle oil 10-40W. Autozone puts it on sale for $2.99 from time to time.

I doubt the oil had anything to do with the starter clutch going bad. I'm new to XJ's but I already have learned that some models seem to be susceptible to starter clutch problems. If I'm wrong about this, someone will correct me. Just the sense I got. But I still would think the oil would not be a factor.

 

I just got the oil changed on the 750:

You should be using 20W40 or 20W50 if the outside temps aren't below 40 degrees.

10W basis oil is for cold weather. As in, doesn't get above 60.

Remember, a starter that isn't spinning vigorously enough will also appear to be a starter clutch problem.

 

I was using 20w50 Mobil1, until I found a local source of 20w-40. West Marine sells it under its own brand, for outboard motors.

 

Brand doesn't matter as much as viscosity and rating. 20W-50, 20W-40, (or even 15W-40) for summer/ with a JASO rating/ certification of MA.

 

K-moe,
+1 on Rotella T diesel oil, $13.00/gal at Wally World.

All the rage at the GS resources forum.

 

Starter is moving pretty good but anyways I'm going to dump the 15w-40 out and grab some good 20w50 I've notice when it gets really hot outside the bike shifts harder then when cold wonder if the oil is thinned out to much ?

 

I've switched to a 20W50 mineral oil this weekend. There's certainly a noticable difference. Starts pretty much the same, but it somehow sounds better and seems to ride better, shifting is very smooth as well now.
