Lots of people have been running lots of old cars, trucks, tractors,
snowmobiles, and other contributors to your cylinder index on unleaded
gas for a long time now. The general consensus is that unless you
really abuse the engine there is generally not a problem.
That being said, if the engine is set up to burn high octane premium,
you probably still should burn high octane premium.
One other thing. Lots of gas now has oxygenating compounds in it
to reduce emissions. These could be alcohols or other chemicals.
Some of these are not too friendly to old rubber or plastic fuel
system components. Some can also be a problem for metal parts like
gas tanks and lines, accelerating corrosion if they sit there for
a long time. The fuel has to be kept fresh or stabilized.
Some states like Minnesota allow some gas dealers to sell non oxygenated
premium for old cars and other old engines. If you can get this,
use it.
