I recently bought a Tiger 2003. In my BMW K1 I always used 10W-50 full synthetic oil. The Triumph service manual says: "Do not use 10W rated oils with a hot viscosity rating greater than 40. For example, DO NOT use an oil 10W-50"
Any idea?
It's got something to do with the friction modifiers in the oil.
10W-50 means it has the viscosity of a 10W when cold and of a 50W when hot...
So, it's probably due to seals, clutch materials, and engine configuration as a whole that the 50W will not allow proper heat distribution within the engine.
My manual says run Mobile 1 4T Motorcycle Full Synthetic 10W-40.
In a pinch, I did run Suzuki 4T Synthetic 10W-40... but that was only because it was all they had.
My handbook says "use 10w/40 or 15w/50 semi or fully synthetic motorcycle engine oil which meets specification API SH (or higher) AND JASO MA" Thats all.
Why not just use what Triumph recommend?
Another oil thread. Do I dare????
What the heck.
In conventional oils, the situation is like this, lets use 10w/40 for an example. It is a 10w oil, that has viscosity improvers added to the mix that allows it to perform as a 40w oil would at the hot temp (forget what the actual temp is, but near 200 degrees I think). So, in a nut shell, conventional multi grade oils are the lighter weight listed, 10w in my example, with VI stabilizers added to the mix so it only thins as much as a 40w oil would when hot.
Now, synthetics are the reverse, without anything added. The same 10w/40 oil would actually be a 40w oil that flows as well as a conventional 10w oil at a really cold temp (whatever the test point is). But here is the catch. The synthetics need no added chemicals to do this, they do it naturally.

Why use something just because Mobil pay Triumph to say use it, its no better than other similar oils on the market.
You asked about viscosity not make. Any 10W/40 synthetic (or part-synthetic) would do.

about sums it up ..oil is oil , the only difference being the additive package that the different manufacturers add to it ...........some use more paraffin , or less , some get more ash , etc. etc
what it boils down to is if you have the right amount of oil you are good to go .
and the difference between regular dino oil and synthetic is : synthetic gets refined more so that all the molecules are guaranteed the same size !
it all comes out of the same hole in the ground :shock:
I think it's almost time to lump all of the oil threads together in 1 spot :roll:

As it happens, Its Castrol now, theyve switched allegiance :lol:

You'd be able to see it from space!
just goes to show what a load of bungcam it is.

Then that'll be the end of the interent cos it'll be full up :XXcomputer
As Arnie says "Oil be back", sorry thats poor :oops:

when I use 10W-40 semi synthetic in my bmw K1, I have a considerable consumption. When I switched to 10w-50 full synth. there is no consumption at all ! So I was verry pleased whith that choice.
That's why.

you found the answer to your own question if you look at the quote above :roll:
owned it a year, done a couple oil changes, always use rotellaT, no probs, and it comes in big ole containers for the trucker types
