Have to agree with Bitsa on that one, they were designed to use mineral oil, so don't waste money on synthetic, there is no real advantage to it, but it has been known to cause clutch slip and clutch drag. Bryan J will be able to tell you the exact grade to get from Tesco, believe it or not, it's a diesel oil!
Tesco 10w/40 mineral oil. I think it is at £16 for 4ltr. A bit over priced for me.
