what oil ?

1999 600 monster, book tells me just the grade, the shop says use semi symthetic, is this correct.

thanks for anticipated help

Semi will be fine for you're 600, I've always used Rock Oil if you want a brand recommendation

wet clutch model? if so semisynth my 750 is wet clutch and i really b****ed it up using full synth oil - it makes the clutch slip and it has taken about 4 - 5 oil changes using semi to stop it. - and i think i may still have to change the clutch plates.

Havoline 10/40 £13 from a Morrisons garage _ thats for 5 litres

Don't Ducati recommend Shell Advance Ultra fully synthetic - or is that just for the later bikes?

I use it in my 695 and it is good stuff - bear in mind that air cooled engines run pretty hot and will trash a lot of oils fairly quickly. I seem to remember using the Shell Advance in my old M600 also and that was fine too.

This is true (although cynically I think that is just a brand tie-in) - certainly I (and others) have had similar wet-clutch slip problems to snakey in the past - whether that was due to the oil or a bad production batch of clutch plates we may never know, but one suggestion is to use a semi-synthetic, and perhaps just change it more often?

I've been using Synthetic SAE 5W/40 (from halfords) in my M600 2001. No clutch or other problems.

Yup me too - but that was on a 1995 M600. Drained off Shell Advance & put semi synthetic (rock oil) back in. Wasted £40 on oil but at least clutch went back to normal ... ho hum

thanks all, it looks like semi syn

You may well have a point about the brand tie-ins. I used the Ducati recommended Shell chain lube and it was absolutely cr*p! Took about two cans of chain cleaner just to get rid of it too.......
