I use NAPA semi-synthetic which is what Steve recommended and I've just stuck with it. It handles the occasional extreme high-temp condition better than regular oil. Swivel feet are definitely the ticket.
On this subject, my engine had the rather flimsy rocker shaft spacers (standard VW) and discovered there is a sturdier solution - the solid spacers with shims. If that improvement hasn't been done yet this is a good one. ************************************ Craig . . . if Rotec has improvements over Ellison I'm very very curious just what they might be? EFS=2's can be found, with some luck. The Rotec is a hugely overpriced copy. When I looked into them some years back out of curiosity, I saw nothing that was an improvement . . . but I've never seen one up close so please note the improvements you've mentioned. And Jeff, my EMPI's have held up well (no cracks) but in following Mark's adventures with Jim Faughn's plane it's clear Revmaster is the place to go. I'm glad to see Joe Horvath is still around. Every time I turn around it seems like someone else has left us. Mike StirewaltKSEE
