    You don't measure mpg in reference to "how many miles to a full tank". When you fill up divide the number of miles you put on by the # of gallons.

    Its like 250ish to 275ish miles per tank. I think its a 16 gallon gas tank but I've only ever put like 12.5 gallons in at around 1/8 tank.

    My ws6 gets 19 in mixed driving. I'm about 50/50 for hiway and city. Out hiways are usually stop and go or speed up and slow down. I'm on the hiway but that isn't really hiway driving.

    Under the same conditions, my DD, a 98 sentra, gets 40 mpg.

    2001 WS6 M6 (stock)

    HIghway I get around 400 miles to the tank, by that I mean before I fill up. Which is about 26.5 gal on avg. (I had my cat replaced lately, maybe it will go up?)

    Around the city I get 260 miles or so before I need to fill up.

    Below is the actual data from mine. This is my 3rd one and I didn't see much difference. This is a mix of highway and city, the best I've ever gotten on an all highway tank of gas was 27.8, with my current car. I've never seen the highway mileage some are getting on any of mine. I also haven't seen any drop with any of the minor mods I've made.


    Date Gallons Price Total Cost Miles Mileage
    2004 622.45 $2.043 $1,271.46 13252 21.290
    2005 834.51 $2.528 $2,109.51 18155 21.755
    2006 707.71 $2.668 $1,888.01 15407 21.770
    2007 220.39 $2.903 $639.84 4791 21.739

    My bone stock 02 WS6/M6 got 28.5 driving out of the Ohio Valley (Dayton) to Bardstown, Ky (just south of Louisville) yesterday. That was w/ mid-grade and running 80 w/ the cruise set. I get about 17.5 mpg running around town in Dayton.

    2001 Firehawk


    My 2001 Formula Firehawk has performance mods that help gas mileage, K&N filter, SLP air lid, smooth bellows, high capacity radiator, and cooling fan control switch. Adding better air flow to mix with the gas and also keeping the motor cool makes for better performance. I calculated 32 miles per gallon from Ft Worth to OK City, uphill and against the wind. And then I got 34 MPG from OK city back to Ft Worth, down hill with the wind. It is cheaper than driving my 88 K-5 Blazer or my 98 Suburban.

    40mph in 6th gear gotta be a bogged down 800rpm. I bearly feel comfortable using 6th gear below 60mph. And honestly 36mpg, come on?!
