Higher MPG with Premium gas?

The difference is in the knock resistance of the fuel. Higher octane will allow the computer to run optimum timing before it starts to knock.

 

Well, it's a fluke. Whatever feeding the information to the gauge was way off.

I finally I drove it bone dry today. 355 miles on this tank, filled it up with 19.6gal. It came out just a hair over 18mpg.

 

Nothing but Shell 93 since day one!

 

Chevron 93 since day 1 and this is what I got yesterday around town and my Tacoma runs like a thunder chicken.

 

I love listening to people trying to self justify wasting their money. All these doomsday predictions of destroying the engine from within by using 87 Octane gasoline is laughable.

 

Same here with the exception of running 87 enough to notice a difference after the switch. Every vehicle is different.

 

Definitely not possible for an entire tank.

 

Averages 22 to 26 mpg.
