Mobil 1 and your bike

[Lou Girardin]

I've used Mobil Racing 4T in our cars (with Mobils blessing) and bikes for years now without problems, but wouldn't use the car oil in a bike.

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.

Funnily enough my bucket did have electric start which was excellent for the Le Mans starts, in the last couple of years I been using different oil and strangely enough I've had a shitload of problems (although I don't think it's related)

Main problem with the Commodores was a decrease in ring tension, although it made the local Automotive engineers a lot richer

Yes,driven by compulsory economy targets in the US,manufacturers have been using all sorts of tricks to lower fuel economy,one is to lower piston ring tension,which is why the Yanks use such incredibly thin oils - 5/30,5/20,0/20.Put a thicker oil like 15/40 into these motors and they burn oil,the oil film overpowers the rings.That's why most friction modified oils are made for the US market,and they are usualy below 10/30.

I've only really used Mobil 1 in my cars and are yet to change the oil in my Bike. 500Km's and is due to be done next Friday.

I used to use an Oil in my efi Rotary 13bt that was Valvoline 20w / 60. I'm yet to see or hear of anyone ever using that oil? I would have thought that would make for a thick yet high temp oil?

.......thick yet high temp oil?

I use 20W/60 in the Alfatoy. Alfa recommend 5W/60 , but thats in cold Europe, and hard to get here.

A flush with some old oil from mella yella and a fresh drop or two of elf oil and its right as rain.

I think the use of elf oil is an abomination.
What about the poor elves' families?
What's next baby oil?

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 totally agree about ATF. I used it in the gearbox of every 2 stroke bike I have owned since 1970. Great clutch feel and nice smooth shifts with no slip.
