New engines naturally run hot until everything breaks in. Do not run a 
synthetic oil until after you 2nd or 3rd oil change. If you do, the rings will 
never seat properly. I forget what size engine you are running. With the miles 
you have on it now, I would add maybe a half of quart of Royal Purple Oil mixed 
in with my regular oil change. I did this to one of my engines that I built and 
it dropped my engine temp by 15 degrees. ---mark

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.
