Shell in my area has up to 10% Ethanol no matter if it's 87,89 or 93 octane as does EVERY chain gas station here. Only Ethanol Free within about 50 miles from me are a couple of independent stations.

But I agree, I normally see 2-3 mpg better with either Ethanol free gas or E10 gas that I've treated with StarTron or a similar Ethanol stabilizer.

You gotta read the pump to know for sure...

 

Shell gas does contain ethanol..And thats a fact!!!!!

 

Well a fact is a fact as long as you have your facts straight

Shell V-Power premium gasoline in Canada does not contain ethanol.

 

And if you race you have a custom tune which eliminates the need for the power wire.

 

All franchised fuel stations will have ethanol. It is government mandated. Only private owned fuel stationsccan obtain and sell non blended fuel. Even then, it is good to buy or make your own ethanol test kit.

Power wires are great little devices. Fuel mileage will vary because there are SO many things that can contribute.

 

I meant all Shell gas in the United States..I should have said that.I didnt expect Canada to be brought up.And I said that because of the government regs.Now that Ive made that clear its still s fact
