Hello list members, Been a while since I've been on the list! Good to be back! Here's the deal. I recently got my '66 Split on the road, with a New (not rebuilt) enine, new transaxle, new brakes, etc., etc., etc. I just had my Dual Weber ICT's rejetted to fit my engine specs. I had Jeff (local vw mechanic guru) rejet the carbs, and diagnose what he thought was causing the bus to run hot. Right now I am running straight 40 weight oil, and my bus is still running hot around town (Gene Berg Dipstick). Are my fellow Texas bus friends running multigrade oil? Are you all running multi grade synthetic oil? Do new engines run hotter until they're broken in? (only about 450 miles on this one) I really don't want to get into a crazy heated debate about oil, a la type2.com list, but I am just curious. I kind of need to sort this out before going on the long treck up to northwestern Arkansas at the end of the month.
