Has anyone dynoed with both to see if one is any better than the other? Also say you use 5 gal 110 and 5 gal of 93 is the octane you have about 101.5??
I know it is less expensive to go the xylene route
When you use Xylene you also have to use some mystery oil or something because Xylene will eat away your fuel lines. I have used Xylene ONCE in my car and pretty much decided it SUCKED and will NEVER make that mistake again.
Xylene doesn't necessarily eat away at your fuel lines but it does remove some the piston lubrication. So it would be best to add synthetic 2-cycle oil like pwpanas suggested.
The mix is usually 70% gas - 30%Xylene
For every gallon of Xylene use 5oz. of oil.
