Therefore, while their V Twin and MTX 10W40 might lubricate the transmission properly, I am not sure whether or not they would affect the stator problem any differently than their 75W90 gear oil. WTF? I can run mobil 1 V twin 20w50 in my tranny?Īs much as I respect Mobil Oils, I would be rather surprised if they were aware of the problem of premature failure of the stator insulation: it is just beginning to be widely recognized on this highly specialized board. I run the V-Twin in my 2000 S3's engine but have never tried the MTX 10W-40 in the transmission. Locally (SC), most Autozone stores carry both of them. Both are fully synthetic and cost about the same thing (~$8/quart). The V-Twin 20W-50 is intended for HD & Buell engines and the MTX 10W-40 is intended for most Japanese bikes. Yea, AFAIK Mobil introduced both oils at the same time. I didnt know it was available until the other day Kewl thanks.was the mobile 1 v twin out at the time. I saw it posted here maybe a year or so ago, so I e-mailed Mobil 1 for myself and asked "What lubricant do you recommend for the tranmission/primary for Buell motorcycles?" They responded and said use MTX 10W-40. I have not heard of this and have been running HD synth 3 in mine but i am tired of giving my money to HD Whodom where did you get that information on the MTX 10w40? Not questioning just like to have fact or a reference for the next time I change my oil and some of the Bad webbers here. I thought that it seemed a little quieter but not sure.maybe just my imagination I just know that it has been running great. I just switched to Mobile 1 v-twin 20w50 this week.not sure if there is a difference in feel or not. If this PLACEBO stuff you speak of can make it faster too, I'll buy all you got! I'm pretty sure my bike gets faster when I wash it, and I know it got faster after I got Erik to sign it. "However never underestimate the POWER of PLACEBO!" I don't see how we can go wrong with this stuff. I'd be willing to bet you're all correct and 95 to 100% of the improvement was due to the shifter shaft replacement and adjustment, not the oil change.Īt any rate, the Formula+ shifts at least as well as the Mobil, costs about the same, doesn't smell nearly as noxious, is available at virtually all HD dealers, and, as far as we know, hasn't eaten a stator yet. Replacing the shifter shaft required the internal linkage to be adjusted.Īfter the oil change and the shaft replacement/adjustment, my shifting is noticeably smoother and neutral is easier to find. I switched from Mobil 1 75W-90 to Formula+ when I replaced my stator a few weeks ago BUT I also replaced my shifter shaft (the end of which was slightly tweaked from a drop before I owned the bike). I did not notice any difference in shifting.
Mobil 1 gear oil in harley transmission plus#
I also switched frome M1 syn 75-90 to HD Formula plus just yesterday based on what people said on this board about stator problems. Mobil recommends the use of Mobil 1 MTX 10W-40, not the V-twin 20W-50 in Buell primaries and transmissions. I purchased the M1 75/90 for my primary and because of too many conflicting comments about the M1 75/90 I decided better safe than sorry and put in Formula+. Mobil 1 V-Twin 20w50 is now approved for use in Primary+Trans.
However never underestimate the POWER of PLACEBO!Ĭant go wrong with factory stuff but I run Amsoil. I think you nailed it And why take a chance?ĭjkaplan Posted on Thursday, September 14, 2006 "I suspect that properly adjusting the level of the transmission fluid, and the primary chain, (two subjects well covered on this board), are more important than the choice of lubricant.
I might follow you in the change, the next time I change I think its going to be amsoil for me. The people that can feel a difference must have calibrated asses. I suspect that properly adjusting the level of the transmission fluid, and the primary chain, (two subjects well covered on this board), are more important than the choice of lubricant.Įxcept for the way synthetic smells when it burns, I've never noticed or felt any kind of difference in any kind of oil I've run in my primary/trans or engine. None the less, I thought I would switch on a "better safe than sorry" basis, and report my findings.įrankly, I could not convince myself that I noticed any difference at all in the way the bike shifts or runs. In addition, I did not feel that the case for damage to the stator had been statistically proved. I hesitated to do this for several reasons, not the least of which was sloth. SWITCHED PRIMARY OIL FROM MOBIL 1 TO HARLEY FORMULA +īased entirely on anecdotal evidence on this board, I decided to replace the Mobil One 75W90 gear oil in my primary with Harley Formula + primary transmission oil, to prevent premature failure of the stator.
