rotell t 5-40 ?
 

after searching. it seems to be the prefered oil, any comments or other suggestion? I am currently using amsoil 10- 40 and at $50 a gallon it doesn't seem worth it to me.

Mobil 1 15-40 full syn, $26 a gallon at Wally World

+1. mobil 1 synth ftw.

Do these bikes use brass synchros in the gearbox?

Rotella and Mobil 1 Racing T4 are great motocycle oil because of the higher level of phosphorus/zinc in them.... Stay away from any oil that states energy conserving due to the wet clutch.

I used to use used Chinese cooking oil, but had to stop cuz my neighbors dogs would follow me to work:)

Now I use M1 15w50
RC

peanut oil ;)

you'd think they would run like hell in the other direction. I'm sure more than one dog has gotten up close and personal with chinese cooking oil.

Perhaps you mean their T15-40? (not trying to be picky about spelling, just being sure about actual product you're talking about)

Anyway, I recently did an oil change to this stuff and I find the bike shifts smoother than before. Some find the same, some do not. I don't know what oil was being used before, but i'll stick with this stuff until I have reason not do. It meets the standards at less cost, so i'm happy.

preeeeeeeeetty sure that their isn't any synchros in a sequential transmission (dog box). Stop me if I am wrong.... not expecting a stop.

Slim, Rotella T doesn't meet the standard, you won't find any approval for motorcycle use on the bottle. I'm not saying that means its junk... But I can't help but feel people will use the cheapest stuff they can find as long as it doesn't have any noticeable downsides.

LOL... Thats funny!!
+2 on 15/40 Mobil1. Use it in all my bikes...

I've been using Rotella T 15-40 for years now. I remember reading an article about oils, and it was actually recommended over many others.

The current "CJ" formulations for Rotella 15w40 mineral and Rotella 5w40 synthetic both meet JASO "MA" standards for motorcycle use.

What I can find is... According to Shell, the Rotella T CJ-4 (diesel) meets the frictional standards of JASO MA, and many other parts of it.

It's not JASO MA certified though.

I already use it in my cars, so I may as well give it a shot in the bike too.

Yeah. Some MC oils have the JASO MA certification label. Others, like the bottle of Castrol 4T I'm looking at right now has a picture of a motorcycle on it, says "meets JASO MA" on the back, but doesn't have the certification label 'cause they don't want to pay to use it.

Still others like Rotella meet the standard but don't have a picture of an MC or JASO claim 'cause they don't want to confuse the 98% of guys who buy it for diesel engines.

You can't go "wrong" buying motorcycle oil, but on the cheap end you can get an oil inferior to the 15w40 stuff, and on the high end you might be paying an extra 6 or 8 bucks a quart for the motorcycle logo on the bottle.

Thank you for keeping an open mind. :) Good luck with it and be sure to pay attention and report back as to any noticeable differences in shift quality of any kind. That stuff just intrigues the heck outta me. :D

I was looking at the Zinc and Phosphorus in the Kendall GT-1 in 20W50 and it looks good for summer use.......

and is only $2.99 a quart at Autozone

Otherwise I can get Honda GN4 10W40for $3.45 a quart at the dealer.

I switched to Mobil from Chevron DELO 15w40, and the bike ran fine with that (diesel engine oil). I figured even though it's twice the price and then some, it's better for the bike and worth the extra $ per year.

The Kendall 20w50 looks strong. Nothing wrong with the Honda GN4 10w40 except that it doesn't look any stouter than the "made for cars" Chevron Supreme, Havoline etc. you can buy on sale for a lot less money.

When I was a kid, Kendall GT was green. If it was still green, I'd buy some just for the hell of it.

The new Kendall is not green as we remember....but a amber color.
A company here in PA makes the grenn stuff now that the Kendall name was sold to conocophillips.

Brad Penn oil uses 100% pure Pennsylvania oil, said to be the purest.. and is refined at the very refinery that the old GT-1 used to be. So basically the Brad Penn oil is the old Kendall GT-1, under a different name.

Crisco's the shit. Cold starts are a bitch but once warmed up (doesn't take too long with all the extra friction) she runs great! I usually top off with used bacon grease because it's good for the top end.

Crisco's for sissies. Fluffo is the way to go.
