OIL VISCOSITY QUESTION.

[Frank.B]

My local Triumph dealer no longer stocks Mobil 1. Instead he has on offer Shell advance 10w40 fully synthetic oil at £36.00 for 4ltrs, which he assures me is perfick' for the 955i tigger.



However I have been offered some Shell Helix Ultra 0w40 fully synthetic oil at a very reasonable price. It is avery high spec oil developed for F1 racing cars i'm told, But do any of you know if  this 0w40 viscosity would be ok to use in the Tigger?...

I'd stick to the 10w40 Shell fully synthetic.

There's obviously a reason why 0w40 is used in a F1 Racing car and I'm sure the techies will tell you why, but the Tiger is a bike. It needs the right oil.

All I'll say is :- apparently you have to be careful with oil specs because of the wet clutch on most bikes. What you should get is "JASO MA" in the specs which says it is OK with wet clutches. Otherwise I see no reason why 0W-40 wouldn't be OK.

I think that it states in the service manual about not using oils with a viscosity below 10.

Ahhhhhhh, another oil question. . .  OIL IS CHEAP!  Use what's called for. There's a world of difference between F1 racing engines (ultra close tollerances, fuel used, etc, etc) and mass produced auto and/or motorcycle engines.  Apples and oranges kind of thing.  Don't risk it just to save a few quid. . .  again, OIL IS CHEAP!

Its also to due with operating temperture of the oil.  F1 cars engines operated at a much higher temp and I bet they spin a lot faster than a tiger.
