Default New Z Owner: Gasoline/Fuel Question

Anyone have any insight as to which type of fuel is best for a Z (Exxon, Shell, etc...)? Obviously we all use 93 octane fuel, but is it bad or harmful to use 93 octane fuel that contains 10% ethanol?

Thanks in advance

Chris

I'm a big fan of Shell gasoline. I have had great results using them, I finally found a place that sold 100% gasoline, no ethanol and got 2mpg better! Performance wise I could not tell any difference. Have yet to find a Shell station that sells no ethanol.

It doesn't matter. Gas is gas. On the east coast, it all comes out of the same pipeline and each company adds their own detergents...

I use Canadian Tire 91 octane gas & get Canadian Tire Money! 7.5¢/litre!

"Gasoline Additives
During the refining stage, Canadian Tire Petroleum product is refined to comply with all government regulations. The additive package in our product is a multifunctional gasoline additive. The package is called Tolad T 3306. The features of this additive are:

Cleans fouled port injectors
Maintains carburetor and fuel injector cleanliness
Corrosion inhibitor in gasoline containing oxygenates
Provides corrosion protection in aqueous layers formed below gasoline

The benefits of the package are that it “provides detergency to keep fuel metering systems clean resulting in improved performance and fuel economy,” and that it “inhibits corrosion, thereby reducing contamination and filter plugging caused by corrosion products.”

Additional cleaning additives can be purchased from your Canadian Tire Petroleum gas bar or store and can be directly added to your gas tank.
The specification of our fuel is automatically changed depending on the time of year. There is not a single day during the year when the switchover takes place. There is a phase-in process from winter spec to summer spec and visa versa, which takes place over a period of several weeks to several months. The specification relates to the cloud point, the pour point, the volatility and the viscosity of the gasoline that is changed."
