If there is ever a last word on anything on this list, I figure it
would be gasoline. It sure isn't oil or tires!

So is there a consensus on the correct octane rating for the vanagon?
Specifically a 2.1.

I have always run high-test in it because when a car is doing well you
hate to change. And years ago I was driving to texas in a 69 aircooled
in really hot weather, and burned a piston running low-test, so I've
just been spooked ever since.

What should I really be running, though?

Thanks,

Jim
