ok after trying to check my mpg i came up with 25..... this just totaly doesnt seem right!
ok i filled up (full tank) my od read 216176. I hit the 3/4 tank mark and it read 216276 so if a 1/4 tank is 4 gallons. i went 100 miles on 1/4 tank so that makes me getting 25 right????

^thats kinda confusing lol

you cannot base it on your gas gauge. The only way to check real world gas mpgs is to: 1. fill your tank up. 2. drive around, til its low. 3. Fillit back up. 4. Divide the miles by the gallons of gas you put in.

Remember the gas gauge does not account for the extra 1-2 gallons at the top of the tank and filler neck.

i see so i should go fill it back up and than what its kinda complicated to me lol

yes fill it up to the "gills" then drive till the gas light comes on your empty... then take how much fuel was in the tank by how many miles your went... write your odo meter at the gas station

Nono, take how much fuel you put into the tank until the pump handle pops off, THEN divide the miles you traveled by the gallons you put into the tank.

That will get your MILES traveled per GALLON of gas used

i have an interesting (newbie) question...is there ANY way i can calculate my mileage without the odometer....because...mine doesnt work...and hasnt worked for what seems to be about since...1983...cuz it only says 43,699....so...is there any way i can calculate my mileage or not...sorry for the thread hijack

only if you know how far you went, say from town a to town b.

Example:

fill up gas tank. Odometer reads 114,969
drive till your tanks low. Odometer reads 115,204 when you fill up.

By that math, you went 235 on that tank or until you filled up. you put in 13.2 gallons. Divide 235 by 13.2 which gives you 17.8 mpg.

Now if you have larger tires and your odometer is off, you need to calculate your differance.



Ken, on yours, do you have a trip odometer? If not, I wonder if theres a GPS system that moniters distance traveled you could purchase.

I think I missed something here



figuring out your fuel mileage,,,,,,,

That's like .......... math........

Like wow man

notanymore

you could get one of those gps things that tracks how far you have traveled and go by that.

Yep, and I always fill up at the exact same pump too, in case one place has a slant at the pump or something you get the same same two times in a row.

Haha made me laugh. Thought the same thing. I teach math--goes to show you need it outside the classroom.

HA! i never thought about that...i have a GPS that does that..thanks guys...lol...i feel like such a damn blonde right now.........o well..now onto to buying batteries for my GPS to get my mileage!!!!

Ken,
