OK, I've asked this DOZENS of times before and CAN'T seem to get a clear answer, I use:
4 GALLONS 100 Unleaded (Sunoco)
1 Gallon of Zylene
That "Should" equal ~104-105 Octane???
I need to keep Unleaded for now (3" High flow Cat) and would like to know if the same percentages apply with Zylene mixing with 100 or 105 Unleaded????
