I have been mobil 1 for awhile now, and my quad has been smoking ever since. But not immediatly after i change the oil. I had my head reseated, and valve seals replaced. The rings are staggered correctly, and are in perfect position, with a proper break in.

The problem is i am buring oil. And i figured out that the mobil is breaking down too fast. Will a synthetic blend cause this? should i go back to honda non synthetic? if not what other sythetic/non synthetic oils could i try that WILL NOT HARM THE CLUTCH. last think i want to do is have to replace a slipping clutch. I am inexperienced in oils and their capabilities. Can someone plz inform me on some oils that i could use.

 

Looks like your oil is too liquid (get a higher viscosity grade)...or you're putting too much of it...or your piston is almost dead...or...It never happened to me, so I can't really be ure of any..but these things up here should give you a direction.

 

Try using castrol gtx 10-40 works great
never had a problem with it or in any
of the number of bikes I've had

 

Your best bet is to get the recommendation right from your engine builder or parts supplier. Other than that, I would recommend one of the four stroke engine oils made specifically for motorcycle engines with a wet clutch. A good parts counterperson can make a recommendation to you. Good luck.

 

ok i found out a few things.

Fact - Mobil one tri-synthetic 15W 50 will not harm the clutch/ whatever, and works extremely well lubricating the engine parts. it also lats alot longer than regular non-synthetic oils.

Opinion of most users, and more - Mobi 1 15 50, tri - synthetic is the best oil you can put in your quad for 4 bucks a quart. there are a few more , 8 bucks a quart, i forget the names but they cannot be found in a convient location. (wal-mart, advance auto) they must be ordered.


the reason i was buring oil was because i was running very rich, causing the oil coating ont he cylinderwall to be burned, since i have rejetted it hasn't been smoking.

This also seems logical due to it only smoked at high rpm's.


thanks for the help
