Hi, I hope someone can point me in the right direction here, my manual for my thonycroft T20 says not to use any other oil apart from CD spec, I belive this has been superceded by CH-4 spec oil, the engines been sitting for over a year now (brand new) and I would like to change the oil before attempting to start it up, I have searched the forum for an answer, couldn't find anything difinitive for thornycroft, so mabey something like 10w-40 semi synthetic? I think the manual(which I don't have on me) said 5w-40, but that's just the temp range I think, any advice welcome
Regards
Pete
