Wow!  I could never drive my old air-cooled 81 like that!  I had oil
temps at 220-260, until I installed an aux oil cooler (no fan), then
it stayed closer to 220 at max. (oil temp, not head temp).  I also
had to keep speeds down to keep the temp down and never got more than
16 mpg!  Congrats- you have a nice air-cooled Vanagon!  Enjoy the
ride - I am sure you did.
