OIL for my XJ1100J

[jokertat2ink]

:Which one would be good for it as I have tried 10w40 full synth and I now have to replace head cover gasket and also the cam chain has sprung a leak. why me. When it is good some say it is to loud my reply. TO LOUD TO BAD. I have now purchased Mobil 1 4T 15w50 at great cost but it is for my Trike and any amount for my engine.

Oil is a personal preference and everyone has their personal favorites. By the manual 20/50 without friction modifiers is what you should use. Synthetic is slipperyer (is that even a word) and can seep out of small holes easier than conventional oil, synthetic also often causes clutch slip on old friction discs.

Try a few oils, find one YOU like and stick with it.

Thanks For The Advice

I guess that I should use the oil that was around when our Machines were in the Showroom and not the new fangle dangle crap. CHEERS N BEERS. JOCK:

i heard u can run diesel oil in this bikes.....

[mfarrington]

diesel 15w40 . . . .

I'm not a mech, but I change my oil every 3K, my filter every 6K, use Rotella 15W40 diesel, and she is smooth as a babies' arse. Most times I shift up without clutch, and she gears real quiet . . .

Get on the throttle and listen to the engine rev as the clutch is slipping. BTDT.

any oils labled energy conserving... (usually on the back of the container)..you do NOT want...They contain Moly which makes the clutch slip...friction modifiers...
Synthetic or Dino is your choice...

Where in hell did you hear that one? I wouldnt run anything on some hearsay...My advice to the OP is to stay with whats been proven and has been used in the bike. If its syntheic or dino stick with it OFC if the wrong oil was used you wouldnt want to continue with that...drain and possibly flush the engine out and refill with the correct stuff

I believe this is base on the fact that many diesel oils are not energy conserving and are in the right range as far as viscosity for our bikes. The wrong thing to think however, which you have stated is to take it as a blanket statement as some diesel oils are energy conserving. I tend to stick with MC specific stuff, primarily because my understanding from my reading is that they use different elastomers (sp) for viscosity stability that stand up to gear shearing a little better than non MC oils. Of course, the key word here is "a little better" cause they still break down a lot faster than in an engine without a gearbox using the same oil.

The point is (which you made as well), use the oil most closely matching the grade and viscosity recommended by Yamaha, although exceeding the grade is fine, and even good an many cases as long as you stay away from energy conserving. An advantage of MC specific oils is they tend to stay away from anything that will adversely affect the wet clutch, and if you stay with the stuff you can get at auto parts stores, you can stay somewhat close to auto oil prices rather than the stupid prices MC shops want for their oil.

Oil and my XJ1100 Maxim

I have got my hands on some Liqui Molly 15w50 sae SJ I am going to give it a try as I have been told sj is good for gear and clutch so I will get the 10w40 synth out and go with a new filter and fill up and I will keep yous informed on what happens. Cheers n Beers Joker.

+1 on the Castrol 4T. It's what I've been running in mine for the last year and a half, and the engine has both sounded better, had NO clutch slip, and the oil comes out nice and black at oil change (a sign that the oil is picking up and taking with it the nasty dirty stuff) (ok, so it's just a nice dark brown). No clattering, no stuff in the filter (before I installed the SOFA that is) and nothing to speak of on the drain plug. Still feels (yes, I'm old school taught by old school mechanics, taught to feel the oil when draining it out) nice and slick and such with no strange smells to the oil at 3k miles which is my oil change interval. Very little oil use in my case, I understand Greg's uses some, but he pushes his a good bit harder than I push mine. I might get an oil analysis done someday, but with the fairing I hear every little noise from the engine, including the oil burbling down the cam chain tunnel back to the bottom of the engine, so I go by the fact that in 20k miles, the engine noises haven't change measurably. I pay attention to both volume an timber of the engine sounds, as any change in those would point to some having gone wrong.
