You guys think you're taking it up the a$$??
I run C16 in the Benz boat. I am on VP's lowest price level. I have been paying $10.78 per gallon for the last 18 months. The price has not gone up with the price of regular fuel. I was actually able to start justifying the price of $10.78 since others are paying $5.00 at the dock for 93. I was informed this week C16 is finally going up. It is going to end up around $14.70 per gallon!!!! The boat is set up with a dual mode ecu. I can run the boat at 1200 HP using 93 octane or at 1550 with C16. We did some calculations. At cruise speed with the ECU set at 1550 it burns 2 1/2 Gallons per mile. That is not 2 1/2 miles per gallon either!!!!
