Tried searching the above but can't seem to find anything. What's our Copen's minimum octane level? And what type of engine oil and auto transmission fluid to use? For engine oil I'm using 5w-40, not sure whether it is suitable or not. Appreciate help. Thanks Regards, Jake. S
Hi, The owners manual states unleaded fuel Octane 90 or higher and 5w-30 engine oil. Can't help on auto transmission as mine is manual. Martin
