just today i filled up with low fuel light on. oh yeah, i had only gone 199.9 miles. that is a whopping 13 mpg. i cant seem to figure out why i am running so rich that i am literally wasting that much gas
Per tank is not a good comparison. We all fill up at different times. When I'm used to a car and my driving is consistant I can get very close to empty. This will change that number. Greenbird included his fill after the mileage per and that's really the only way to compare.
Since it's mileage per tank the thread asks for I was usually cracking 500kms (300miles) and did a 600 (360) after a straight highway run.
I get 280 almost every tank to the light coming on, and filling with 15 gallons. More specifically around 18 mpg in 100% city driving, in the 97 with a tune from Lonnie burning 91, 3.27 gears.
I get 290 miles in the 89 Cougar, but I usually put in 17 gallons at that point (different amount left when it wants me to get gas, and larger gas tank) so around 17 mpg.
I got 28 mpg on the one trip it has been on (a TCCoA meet in Phoenix) in the 97, same trip the 89 got 23 mpg (yes I took both cars to the meet since I was the only one with Cougars I wanted them represented, if not well, then by sheer numbers) , I have a 2000 Grand Marquis for anything that involves driving longer than 20 miles (but for no other reason than it hold my family of 4 better and I want it to get all the high accumulated miles).
My wife gets 350 miles to the light in my 2000 Grand Marquis (with 2.73 gears), and that is around 19 mpg, strictly city miles too. It is in dire need of some 3.27s, like my 97 is in need of some 3.73s.
Miles to the tank is not a good gauge, you need to try to figure it out mpg which even with variances with how full you actually get it, is more precise and meaningful unless you try to go a mile further than you can on a tank.
