When I checked the compression on my TD vanagon all four were within 5 psi of
each other. 3 were 400 and the fourth was 395. I was a little concerned,
but the engine ran fantastic, so I've continued to drive it. My friend's
quantum checked out at 380 on all four. I recently got thinking about the fact that
I live at about 7,000 ft. When the altitude compensation is factored in to
my friend's engine his compression at sea level is 460 psi. My TD vanagon
engine would read 475-480 psi! Nothing wrong with that!
I was also thinking about the recent discussion of Passats running on low,
mid or high grade fuel. Someone mentioned that some people saw no performance
decrease or mileage decrease with the lower grades, others saw significant
difference. I got thinking that probably the cars seeing no change were primarily
at high altitudes. I'd love to have that member of the group post that idea
to the passat group. It makes me think that I've been wasteing my money
putting high test in my ABA work van.
