I found the same issue. The only Castrol oil I can find in stores has an API rating of SL or SM. Not the recommended SH? Usually an oil question will be ignored or cause a million different opinions. Did you try doing a search?

Cycle Gear carries the recommended Castrol oil, though that may not help you in Canada. Too bad you can't get it at Tim Hortons, they seem to be everywhere up there.

The brand isn't critical. In fact, BMW now uses Spectro oils in the same weight and class ratings.

What is important is the specification. Whatever brand you get, make sure it's 10w-40 API SG, JASO MA (the last bit means no friction modifiers, which is important for a wet clutch).

Folks around here either go with one of the above, or Amsoil, or Mobil 1 4T, or pretty much anything that meets the above specs.

Oh, and the trick to searching for oil threads is to search for the term "JASO".

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

I believe the SL and SM ratings are higher than the SH rated oils... I would think you'd be better off with the SL or SM.

That Castrol is a European type of oil not availabe herel, I am using Amsoil in mine. I was told by my Service advisor not to use Synth oil until after 6000 mile mark per BMW recomendation. I was told that Spectro brand oil is the company that packages BMW bike oil.

The S# ratings are backwards compatible, meaning a "higher" rating will work in place of a "lower" one. But it's the JASO MA rating that's critical. That's what you need for motors that share oil between the motor, transmission, and clutch.

You might find it cheaper.

Also, don't forget to change your final drive oil too!

Agreed, but I wasn't sure if the higher ratings then came with friction modifiers. Thanks for the clarification.

You will not find the JASO MA spec in automotive synthetics. It will be in a motorcycle specific oil. BTW, the AMSOIL website has an excellent white paper on their M/C oil page that is well worth reading.
