Has anyone used Fuel On before? It is an additive (not cheap per bottle) that you add to your gas. It helps increase MPG! I used it in an old Taurus I used to have and it worked there so I tried it for the RX and what do you know---it's working.

So far so good. Just an ounce or two is required per tank full.

I know everyone is hesitant on using additives. I just figured I'd let you know in case you are at your wits end with bad fuel economy. I could only find it at Parts Plus Auto Part Stores.

How much of a differance in mpg?

 

About 3 MPG right now but I'm awaiting my M flash this Wednesday (Mazda keeps pushing my appt. up).

After the M flash helps stabilize the gas mileage, I will recalculate the MPG then try again. I'll let you know if it goes any higher then 3MPG

 

3 mpg more than what? What did you start with as an average?

 

14 MPG before M flash, 17MPG before M Flash with Fuel On.

Same Highway route each morning. Yes, I meant highway.

14 mpg highway?! Man, that is horrible. I get about 14 mpg but it is all stop and go city driving. Highway I jump to about 19 mpg. I would think there may be something more serious wrong with your car. I would bring it to Mazda and explain to them your situation.

If you get 14 mpg highway, what do you get in city driving?
