For grins I put about 2 gallons of 110 Avgas in with about 15 gallons of 92,
(that's as good as it gets here) and besides having it smell better it did add
a bit of power. Didn't expect much, but it was only $4.50, 92 is $3.00, so
for $3 more it was cheaper than trying the "octane boosters". I don't do it
all the time because the type of driving here doesn't justify it, but every
once in a while, why not!
Nothing like a little bump for fun.
