Mobil 1 and your bike

[FROSTY:Me]

Just a word of warning to anyone that thinks oil is oil is oil.
The bike I've "borrowed" had a recent oil change. I went to start it cold the other morning and the starter clutch wouldn't engage.
Turns out the silly bugger had changed the oil and put mobil 1 car oil in it
A flush with some old oil from mella yella and a fresh drop or two of elf oil and its right as rain.
So when changing your oil --make sure the stuff ya put in is motorcycle rated definitely not friction modified

[White trash]

Bear in mind though, that there is Mobil 1 bike oil. In fact, it's all the Triumph factory will let you use in their bikes if you want a warranty.

Are you blaming Mobil 1? You're right that oils do have different additive packages. Normal car Mobil 1 should NOT be used for bikes with wet clutches because of the friction modifiers increasing the risk of clutch slippage. You can get Mobil 1 motorcycle oils specifically without certain parts of the additive package. I've run my bikes and cars on Mobil 1 for years but when I bought the Blackbird, I discontinued using Mobil 4T Racing (bike specific) because Honda recommend using semi-synthetic. I now use Motul 5100. Mobil 1 will stay the oil of choice in our cars.

I don't think M1 is friction modified,kinda pointless.There are motorcycle and diesel Mobil 1 versions - the difference is less viscosity improvers,higher flash point,more antiwear additives(zinc,moly) and is more polar,whatever that means.Friction modified oils are for the US market,normaly 10/30 and thinner and all to do with passing economy tests.Mobil 1 from Repco and the like is usualy 5/50,for a bike you want 15/50 or 10/40.

Mobil 4T race in my GSXR1100 caused good clutch launches but hard to select neutral (clutch didn't seem to properly engage) & Silkolene in the Hayabusa finds neutral OK but the clutch grabs on partial release on launch.

Modified my origonal post--Im talking car oil not bike specific oil.
As I understand it mobil 1 CAR oil is a synthetic oil with some friction modification.
Holden were having a shit load of trouble with rings not bedding in in their V8's -the Mobile one wouldn't let em bed in

Are you blaming Mobil 1?

Yep I sure am--Take it out put normal oil in park the bike 24 hours --it starts right as rain. -

There was more to the problems with the Holdens than the type of oil that was being used in the motor

I used Mobil 1 car oil in my bucket for two years with no problems at all,although normally I would always use a motorcyclce oil, errrrrr except for the XJ which I just use whatever's lying around as it goes through a bit

I dont doubt it mrate--but it was definitely a contributing factor.
I'd guess your bucket soesn't have a lekkie start ol son --it was the starter clutch that diddn't work. Seemed like a case of the oil was too good.

Motorcycle oils have more moly than car oils,you'd that would make clutches slip more.I reckon the 5/50 would be too thin at low temps.Funny stuff oil in bikes - I ran Silkoline Pro 4 10/40 in my XLV750 because 10/40 was the recommended oil,so ran that in the XT and TLR200.The TLR has always been hard to find neutral,but then when I sold the XLV used the off road 15/50 Pro 4....now the TLR is easy to find neutral,specialy when cold - you'd think the thicker oil would make it harder to find neutral.

What would be the best oil to reduce clutch slippage?

[Motu]

What would be the best oil to reduce clutch slippage?

ATF,it's made for multiplate clutch packs - but not very good for your engine - wet sump bikes are such a compromise,the Poms had it right...seperate oils for engine,gearbox and clutch.Of course the correct answer is your clutch shouldn't slip - so something is wrong with it,or you have increased the power of the engine and now the clutch is too weak.

I STAND BY MOBIL 1 FOR BIKES , I BELIEVE IT REPRESENTS BEST VALUE FOR MONEY , ITS CHEAPER THAN SOME OTHER BRANDS SEMIS

[Sensei]

Ran Spectra Gold in my GSXR1100 for 6 years . Dragged it the whole time excellent no clutch slipping Etc . Use Spectra Semi 10/40 in the K3 Mint
