Gas mileage gone bad.

[tonycarreon]

the gauge is not a reliable means of knowing your consumption...



i did not get 400 miles from a tank of gas on this trip.

what i have learned from my gauge:
- needle hits 3/4 tank after about 50 miles.
- needle hits 2/4 ( ) tank after about 200 miles.
- needle hits 1/4 tank after about 260 miles.
- gas warning light comes on around 310 miles.

Tony, congrats on your 1,000th post!

Yesterday, as I hit 200 miles on the current tank, my van's fuel gauge was reading just over 3/4 tank. By that estimate, I should be getting over 800 miles per 20 tallon tank. Roughly, 40 MPG. However, grossly inaccurate. Sure enough, after just over 500 miles, I was empty. Came out to about 26 MPG, which is normal.

Here are my gas mileage results for my 2.7L. Very interesting difference between city and highway and type of driving.

90% city driving, 10% highway. Daily to/from work. Spirited driving. Shift at 3000-4000. Sometimes at 5000rpm when accelerating quicker. Stuck in traffic half the time. A/C On most of the time. 20 lbs of tools in the trunk.

1/4 tank = 49 miles
1/2 tank = 122 miles
3/4 tank = 190 miles
7/8 tank(Gas Light) = 222 miles

90% highway, 10% city. I took a 3 hour trip to visit gf when testing this.
Mostly between 3000-3300 rpm, 5th gear. 30 miles cruise control @3100rpm. A/C On. 50 lbs of luggage in trunk. Average outside temperature of 98F.

1/4 tank = 103 miles
1/2 tank = 220 miles

Refilled gas tank when I reached half tank/220 miles. According to the gas gauge and the pump, the first half of the tank is exactly 9 gallons of gas.

On the way back from my 3 hour trip.
Driving faster mostly between 3200-4100 rpm, 5th gear. Never used cruise control. A/C On. 60 lbs of luggage in trunk. Average outside temperature of 94F.

1/4 tank = 120 miles
1/2 tank = 222 miles
