Hi i agree synthetic oil does not do the clutch any good but i disagree with gaskets and oil seals how can synthetic oil affect oil seals and gaskets i have 13 bikes of all makes 10 of them 60s and 70s inc my sandcast im in the motor trade so i have 10/30 semi synthetic car oil in 45gallon drums ive used it in all my old bikes for the last 20 years and im not a polisher i use all my bikes all year round no problems with seals or gaskets leaking the only problem i had a few years ago was clutch slip on my cbx 1000 but i am shure it was just old age i replaced it and carried on using same oil no more problems lets face it we are dealing with very old tech on our bikes (sandcasts) u could run them on chip fat and they would be ok most owners of sandcasts never ride them anyway so it definitely wont matter what oil they use

Regards
