Octane??

I thought the owners manual said 91

I say's on the tunnel sticker 91 min. So I run that or higher to save a couple of bucks might avoid problems later.

thats 91 RON which is our 87AKI (in north america) rated fuel, aka regular.

I'd bet a lot of you guys who are buying premium are actually getting regular or 89 at best. Seen a lot of 2 smokes go down around here because of watered down gas, happens a lot more than you think, and is one of the main reasons I don't have boost yet...

Most newer station pumps have a single hose for 3 grades of fuel. Imagine your only buying 5gal and the guy before you used regular, how much volume is there in the hose??? Just saying...

I notice I get better mileage running super.

Thats because it doesn't contain ethanol. No other reason. Ethonol only has about 67% of the BTU energy as gasoline.

What is the opinion of using a treatment for the ethanol, I think it is the blue stuff?
