4.0 gas mileage went way up!
i put a full can of seafoam in the tank with 87 octane. and usually it burns a quarter tank for every 50-55 miles or even less with how crapy gas has been lately. well right now im at right over 80 miles on the tank and it just got to 3/4. weird thing is i didnt see anything on the can that said it would increase the mileage. i have done this one time before and got the same results. it did NOT do as good with 93 the one time i tried it though.

I wouldn't get too excited about it yet. My gas gauge changed on me about a year ago, and a quarter of a tank was no longer the same quarter of a tank that it used to be. It was like it got hung up at a quarter of a tank. Still got the same gas mileage on the entire tank though. I wouldn't think too much about it until you run the whole tank and calculate the actual gas mileage.
I hope it went up though.

Mine averages 17 mpg with mixed driving, 19ish Highway. Just converted that from metric. Did not know what it was in mpg just how many km's i got out of a 55L fill up!! Seems average from this. That is with iridium plugs, exhaust and programmed with a performance setting, but I also have a heavy foot.. I should see what i can get out of the fuel economy tune

i do have larger that stock tires so what do i need to multiply the odometer by to know how many miles i have actually gone?

I can't wait to do this to mine. I did it last august, put it through the vac line and the gas tank it did wonders for my mileage. Just got to make sure you replace the spark plugs when you seafoam it through the Vac Line. Right now I'm getting 12 miles to the gallon, really bad I know.
