propane/diesel, or both? Is this something People are doing

Are you talking about
compression? Like I've heard of 10:1 - but you're
saying that propane =
has
really high octane.... Is this always the case with
propane??? And =
since it
has high octane, then if propane can be found
everywhere (like even =
in
Mexico), then couldn't you more readily use an
engine (other than the =
WBX)
that demands high octane (like some of the five
cylinders do) if it =
were
converted to propane???
>>> Yes, I'm talking about =
compression
ratio. Propane in North America is high octane. I guess you could =
use any
gasoline engine, not only high compression. On other conversions =
I've
done, 10:1 jetta gli for example, you can advance the
timing several degrees. Propane also works good with
turbocharging, because of the octane.

But if petrol goes through the roof, then propane

use them
on gas engines...

Propane will

(and elsewhere) you can/could buy a VW golf with factory propane, but I =

What

No

You're first choice would be a diesel TDI.... so I guess that means =
you
can't combine petrol and propane in a duel fuel setup...

Or are you just trying to save fuel costs on both ends of the
