Appreciate the info, I've been running Castrol Power 1 fully synthetic all season with no issues but have not pulled engine apart to see how she looks although if I did, as I don't know what she looked like before I couldn't say conclusively whether or not it was due to oil.

I have always run my track bikes on Castrol fully synthetic because synthetic base stocks cope with higher temps better than mineral base stocks which you will find in semi synthetics. Never had any issues clutch slip, wear or anything else so was interested in the original comment of don't use fully synthetic.

I use the stuff I found in my mates garage, light brown gooey stuff with the picture of bees on the front. My filter is dead clean an the exhaust fumes smell lovely.

Neither of them for me Steve
If I have to buy my oil I use Silkolene 15W50 in my Ducatis
Used Silkolene Pro 4 in my CBR600 and CBR900 race bikes then switched to comp 4 for the TL and 916 in Sound of Thunder, never had a probelm with any of the engines

When Shell Sponsored us with oil I used their 10W40 fully synth, which was fine in the 583 but when I used it in the 620 I found it made the clutch slip, so I ended up beefing up the clutch and switching to Silkolene Semi Synth.

As for Rock Oil 10 years ago I was advised not to use it in my Ducati engines, so I haven't

After my Donny blow up I've switched to Motul300v 15/50, its fkin expensive but it coats and clings really well. No clutch slip whatsoever either.

Lovely Stuff, but as you say a bit pricey

Cos it's made from rocks.

Frack me. Is it really?

Nothing wrong with Roc oil in a Ducati! Ran it in my DD bikes for 5yrs & still run it in my super twin.
