i hate full services places. I had some retard accidentally filling 2 litres of regular 87.

 

Also make sure to always fill up the same way. Meaning stopping right after the pump shuts off automatically and not topping off at all. I think it helps with the accuracy. I still can't believe my 10 year old gti has a mpg meter and the s2k doesn't.

 

I fill it all the way up and by the time I look back at the meter its already empty =(

 

[QUOTE=boofer,Nov 7 2007, 12:43 PM] you realize you could just divide the number of miles into the number of gallons of gasoline that you put into the car, right?

 

ok, well you guys have fun with your fuzzy math. it's not like driving 3/4 of a tank and refilling is going to get you more accurate numbers than driving 7/8 of a tank and refilling. i honestly wouldn't care unless i dropped under 20mpg. otherwise, there's usually a reason why i average 22mpg vs. 28 (driving style)....

 

My gas light shows more often than not. I typically put only 10 dollars in at a time (2.5 gallons or so with 15mpg).

 

I figure if I add only 5 gallons I can save about 56 lbs.

1 gallon of water equals 8.33 lbs.
1 gallon of gasoline equals 5.8 to 6.5 lbs.
1 gallon of ethanol equals 6.59 lbs.

I run it until the last bar is gone then add exactly 5 gallons, not paying any attention to price. I usually go 115-130 miles before I repeat. My car seems to get better then advertised milage and that is with 85% city driving and a number of trips to VTEC. I was surprised so I did a few back to back full-fill-ups at the same station on the same pump for calculation. Same result, I get about 25MPG.

I usually fill up and calculate milage on road trips though. My last road trip to Dallas I got 28MPG and that was highway doing 80MPH with AC on in the middle of August. I have seen some posts of people complaining about milage but no complaints here. I average better then the sticker said I would and I drive heavy footed, that makes me happy.

Maybe it's the CAI and TP, both mods save a little weight... I remove the spare tire when in the city but leave the tools. The aluminum lugs probably don't save much weight but they look cool... Could be in good tune (20k).

 

I fill up 60 miles after the gas light turns on. The light flips on when i have 3 gallons left, so i figure if i estimate 20mpg from that point, I should be safe...i usually actually underestimate it and can get more than 60 miles past empty =)

I average 310 miles per tank

 

There's no way on earth I can get over 210 miles per tank.

 

Do you have a special light or something? I thought there was only 2 gallons left when the light came on
