What fuel octane is required?
The use of 91 octane fuel is generally required for use with all modern supercharger systems, regardless of brand. However, the fact that ProCharger Marine systems produce the coolest air temperatures means that some ProCharger applications will be safe with 89 octane fuel. In particular, an M-3 or M-3SC ProCharger with an AW-504 intercooler is a great combination for customers who do not have access to 91 octane fuel and will be running low boost levels.
