Hi Guys
sure this has been covered a few times before but.......
What oil do you use? Not so much the make but what viscosity? Tell you why I ask:

I was at one of our local race meetings and a some guy who claimed to be a "Ducati Mechanic" asked what oil i was using - told him Castrol R4 Superbike 5W-40. Big fowns and shakes of the head "not right you should use at least 20W-60" Really? He then went on further to say it will cause most problems with the operation of the clutch..................that's when i stopped listening.

I have been using this oil for over a year now and have done 7 race meetings and it been all good. Is 5w-40 too thin for our motors?

I don't think I'd use 5w-40

I`m running 20W-50 as recommended in the user manual. (Used Castol mineral in the past now AGIP synthetic)

Unless you have an engine conversion the next time you see this guy you tell him you have a dry clutch. ;)

G - hence why i stopped listening to the guy...........
I had to show him the holes in my clutch cover to prove it's a dry clutch!!!


Higgy why 0W and why not specifically 5W? Just means at winter tempertures 0 is slighty thinner than 5. I was more concerned about the 40 but having done a fair bit of research now a 10W40 semi or fully synthetic is recommneded by most for our engine.

0w is completely different than 5w

0w dies not change viscosity regardless of temp

I've run 20/50 mineral in all my bikes ( except the bevel and that could change soon as well) and have never had a problem.I'll be putting the same in the Sport when it's time.

Bevel: HD50 Oil
907 w ST3 engine: 10W50

The lower number can roughly be seen as the value for the viscosity when cold-starting the engine.
The higher number shows abstract the temperature where the critical viscosity is reached.
My Bevel is nearly never "cold started" so it gets the HD50...
