Hi Robert,
  I have a new to me 1990 Vanagon GL with 2.1L motor with newly  rebuilt
heads.  I have no idea on the actually mileage of the motor but I  believe it
is high.  I was and still am getting between 19 and 21 MPG  before and after
rebuilt heads.  It depends on highway or around town  driving for me.

Regards,
David

So I  just got done with my 1st 1,000 miles on my 2.1L auto  1988
Wolfsburg.

Before the rebuild I would be average on a full tank  down to nothing
200 miles per tank, note that this with with poor  compression on 2
heads.

With the rebuild now I am seeing 320 miles!  I just filled the tank
with 14 gallons of gas which means I am getting  close to 22.8MPG.
Which seems amazing.

Can anyone tell me if this is  normal or above  average?
