Even if you are driving down hill most of the way still will never get 12 MPG. Most people do not know the correct way to calculate this.
It is very simple make sure you START with FULL a tank of fuel.
Record your STARTING MILES and keep all fuel tickets for your trip.
At the end of your trip just before you park it FILL it up again.
As you started your trip with a FULL TANK so you need to park it FULL.
Record your FINISH MILES and add up all of the GALLONS purchased.
Do not forget the gallons for your last fill up just before you park it.
TOTAL MILES divided by TOTAL GALLONS purchased = MPG
Now I take it to the next level just because that is what I do.
My reports for each trip also include:
1. Location of each fill up Date and Time.
2. Distance traveled between stops.
3. Number of hours the generator is used START to FINISH.
I then calculate the hours used @ 1/2 gallon per hour. I will then deduct the number of gallons the generator used to give me a better indication of the MPG for the MH.
Thanks, I was wondering how many gallons per hour to allow for the diesel gen set. Last trip was a bit of a freak thing and I didn't use gen set at all and got 11.1 with toad, but again that is at 50 mph 1450 rpm's. I wish I could judge when the tank is full, it keeps spilling out when it gets full. I try to listen for the change in pitch when it gets near full but it is hard to hear with all the outside noise.
