0W-40 oil

[welshie]

I have bought oil today ready to do an oil change, and had a good deal on "Mobil 1 new life 0W-40" fully synthetic oil.
Now I am home I am wondering if this oil will be too thin. Will it cause any harm to the engine?
I would appriciate your thoughts on this.
Cheers Graham

Yes you are spot on, I had a real stupid moment there, I never even thought about having to get motorcycle specific oil, doh.
I will take it back and change it today.
The reduced price shoved all the common sense out of my head.
Thanks for that guys.

..whatever ya use, make sure it doesn't say 'energy conserving' on the little round label on the back of the bottle or jug..or your clutch will slip..

Carpenter uses Joe Gibbs oil. Does anyone know if it meets the wet clutch specs. described?
Is this the Gibbs he uses?

Carpenter also uses heavier clutch springs so you can get away with friction modifiers. So while were on the subject . I was talking to Lake Speed Jr. of Joe Gibbs drive oil company and what most peopel do not know is there are some friction modifiers out there that do not hurt wet clutches. Of course you have to buy the right oil. Most car oils have the fricton modifiers that are not men for wet clutchs but using heavier clutch springs like Bob Carpenter uses negates that problem. Myself I use Joe Gibbs Driven oils mostly because they are heavy in wear inhibitors. This time I am trying another brand og Joe gibbs oil that has some friction modifier added with the anti wear inhibitors these friction modifiers that they are using are ment for wet clutch motorcycles. Another thing to pay attention to when buying Joe Gibbs oil is are you buying a non detergent oil or a detergent oil. Non detergent oils do not last as long but then they are usually used on a race track where your changing oils often. If you running 5000 miles or so then I would use a detergent oil. Oils that are made for race tracks and turbo diesels have more goodies in them that the EPA does not like which means they are good its just the EPA does not control oils on tracks they worry about whats being used on the highways. I must ask though what made you decide to buy a 0W40 weight?

Now about the 0w40 wieght oil Sounds like its a turbo diesel oil and it surely wil be thin during the winter months which is what the OW is for otherwise the 40 weight will probably be ok if your not in a real hot area. What really matters is what the bearing clearances are set at looser clearances thicker oils tighter then thinner Oils.

Please go get some some 10-50 or some 15-50 like Triumph says.

What made me buy 0W40 oil really was the good price they were offering it at. It was a Castrol oil which I have always trusted, and the blurb on the can made it out to be really good.
I just never thought about the clutch issue. I will not use it in the bike now, I have bought Castrol Power1 4T 10-30 oil instead, which I have used before as recommended by a Triuimph dealer.
