Average Miles Per Gallon
Did a test for a few days this past week. I filled up the car till the pump stopped. I then drove 307 miles (3 days to work and back home), and filled up again.
Dashboard said 18.4 Average MPG.
307 miles / 16.676 gallons of gas = 18.409 MPG :yesnod:

Re: Average Miles Per Gallon (ZBRA)
Yeah that is actually pretty poor milage right there. I normally average about 22-23 on that particular stretch of highway because you area constantly going up and down hills. When I went to bowling green I averaged 27.5mpg. I'm trying to find out why it is down about 4-5 right now. Other people in the immediate area have reported the same thing, so it is sort of odd.

Re: Average Miles Per Gallon (scorp508)
I am doing about the same thing here. I quit resetting my MPG monitor and for the past 3 weeks I have been averaging 22.3 mpg but alot of this is city driving. If I am driving Highway only I have been averaging 30.7 on roads that have 55 mph limits(which i drive 60-63) and 27.5 on 70 mph limits (which I drive 75-78). :yesnod: Scorp how much stop and go traffic are you in with that average you stated?

Re: Average Miles Per Gallon (CowboyNVette)
I usually get about 15 in the city, but then again this time a year I always start the car for about 10 minutes before I head out.....that really kills my average!

From my house to the highway is 2.5 miles, and 2 stops (3 if the one light is red). Of course I'm on the gas hard from the 2nd/3rd stop as the car is warmed up by then.
I take two highways, so there are a couple more off/on ramps. After that is a 3.5 mile drive to work that has 3 stoplights that I normally hit all red in the morning with some stop & go.
I drive between 75-80mph which shows 22-24mpg on the instant gauge, but the hills kill some of that. That speed used to be 24-26.
Fastguy was told that the additives added in our gas during winter could be the cause. He is also down about 4mpg from his normal average. We have no clue how true this is.

Re: Average Miles Per Gallon (vader86)
Finally some realistic #'s... I was wondering.... on 200 mile + trips my '88 is 23-25 hwy (@ 75-80 MPH) and 20-21 overall... I remember reading guys saying 30 hwy (I wondered if they drove 55)

I get only 10 mpg. But I think it has something to do with cracking her open every time I see a nice straight away! :blueangel:

Re: Average Miles Per Gallon (eamador11)
Ive had the same question. Ive always averaged 21- 23 highway/ street-- more highway. Latley it dropped to 18.x and so I replaced the O2 sensor. Its up to 20.4 but almost pure highway-- shouldnt it be higher? :confused:

Re: Average Miles Per Gallon (Jsailor24)
Almost all of the major brand gas dealers change the additives to match the season. That may have an effect on the mileage.
Off-brand stations buy gas from the majors but it's "out of season" stuff and part of the reason it's cheaper.
At least that's the way it was back when I was a station manager.
For the three seasons where I drive the car a lot I average 20 - 21 around town and 28-29 on the road.

Re: Average Miles Per Gallon (scorp508)
When I take an occasional highway trip to Orlando, I average about 29-31 MPG at a steady 70-80 MPH. When it's over, the average mileage readout says about 24-27 MPG.
Around town, it usually says between 14-17 MPG.

Re: Average Miles Per Gallon (BBA)
Around 27 mpg on trips no A/C
Around 24 mpg in town no A/C
I only drive mine maybe on Friday to work and maybe take a ride on Sundays.

Re: Average Miles Per Gallon (scorp508)
My readout usually says around 20.5. When I checked wuth actual milage divided by gallons, it's the same. Remarkable, I think. The O2 sensor will lower milage. There seems to be quite a spread in milage on this thread :boxing
