I’ve been searching on the site about oil recommendations for my 68 VW Karmann Ghia. I’ve had it about a year and it’s just been sitting but it’s time to spin it around. It’s air cooled of course and I know SAE30 was what they recommended when it was new, but today’s oils different/better or in some cases worse I guess for the flat tappets. I’ve read a lot on here about zinc content so my question is would Rotella T6 be a good way to go or is there something you guys would recommend? Oil is cheap, engines are expensive so the cost of synthetic oil vs conventional isn’t a concern to me. I just want good protection for it. Also what about gear oil for the transaxle? What would be good there too?
