[TR] Fuel

[Geo Hahn]

I find I can use regular in my TR4 if it is Shell or Chevron - but gas
from the cheap places (like Costco) has to be the premium selection or I
get pinging.

I never had a no-lead issue until I did a steady 80 mph drive from CA to AZ
- I think that was what pushed it over the edge as upon getting home I was
unable to adjust one of the exhaust valves, just too much recession.

After that I got hardened seats installed.  But, IMO, no harm in waiting
until the problem arises before taking that step (unless you have the head
off for other reasons).
