Anybody using Full Synthetic Oil..

[Slyder]

I once used Amsoil. The bottle itself said for motorcycles. Yea, my clutch was slipping in no time.

As Mark and others say.......bike specific oils exist for a reason. A $212 clutch replacement was an expensive way to learn that one...needless to say, I now have no trouble dropping $16 / litre for Motul 300v.

I've always found this issue puzzling. I started using synthetic car oils in my GSXR at the 30,000 mile mark{just under 90,000 now}, and I've never had a slipping issue. The same with my 93 GSX1100G, that I bought at 15,000+ miles and now has 55,000+ miles, with the original clutch. On the GSXR I use oem plates with Barnett springs. Maybe that accounts for the GSXR, but the "G" is bone stock. Even then, if the clutch starts to slip, that would be a sign of better lubricity. Just go to better clutch springs and enjoy a little less wear and maybe a little extra HP{possibly on both}. Over the years, I've seen an assortment of oil tests that didn't decisively prove that m/c specific oils were better in a m/c motor/gearbox. As stated in my earlier post, M1 15W-50 in both the GSXR and the G. I have to wonder in a very skeptical sense, if some OEM clutches are a bit underdesigned, to be that fussy with oil. Even with my GSXR putting out about 40+ more hp at the rear wheel than stock, it doesn't have a slip issue. It has to be a real issue, as it never seems to go away.

You're kidding right? At the shop I used to work at we used Amsoil synthetic exclusively in pretty much every bike and never had a customer with a single complaint. I have also used it in all of my bikes and never had a problem...

....55,000 miles on the original clutch...I find that hard to believe.How is it that you consider the clutch slipping to be o.k.?

Nope...not kidding. It was regular Amsoil, not a bike specific one. It wasn't meant for wet clutches, though it did say "for motorcycles" and a list of others, cars trucks etc. After that incident I used Amsoil that was meant for motorcycles with wet clutches and had no problems. After I got the 1000 and broke it in for a few thousand miles on dino oil I switched to Motul. And, no problems.

The weird thing is I don't even think we used the bike specific oil.

No BS. No slippage. OEM original clutch at 55,000+ miles. I can't change the springs either, as it has a diaphram type spring. I've even gone to the drags with it twice {11.8 @ 112mph} still no slippage. The worst thing it does, is an occasional chatter if I'm sloppy on take off. No in gear slippage under heavy loading. Maybe some of you young fellows need some lessons on how to use a clutch. To be fair, I have toasted clutches on my GSXR, and I mean toasted. 20,000 on the first OEM. Almost 30,000 on my first full Barnett clutch {plates and springs}. About 30,000 on my second Barnett plate set, and I'm on another set of OEMs but with the Barnett springs. The first three clutches saw lots of NED grudge nights. This OEM has seen one grudge night and a bunch of trackdays. Still, after all this babbling, no synthetic oil related slippage. I have no need to BS anybody, but because of my experiences, I still am puzzled when I hear of this kind of slippage.

M1 15W-50

Does it say "energy conserving" on the bottle?
The M1 15/50 used to be (and may still be) the one car viscosity they made that DIDN'T have friction modifiers... that's what would cause clutch slippage.
If so, using the M1 without those modifiers isn't in the least bit conclusive.

You are correct. It doesn't have the friction modifiers. I have also read that Mobil says the 15w-50 is the only "auto" oil they recommend for use in a bike.
The "diesel" oils, I believe, also do not have the friction modifiers. Maybe the discussion should focus on "friction modified" oils instead of just synthetics.
Going in that direction, since the friction modifiers are put in there to make the EPA happy, is there anybody out there who has had this problem with a "FM'd" dino auto oil?

You should get a few guys and lift it up.

Oh man....I thought this officially died too.

I use car oil in the TL (no trouble) & used car oil in every bike before that.. No such thing as full Synthetic. Fully Synthetic yes, all Synthetic oils have dino oil in the MSDS...
