The link below provides a good overview of all of the factors affecting fuel economy and the importance of each factor. While it is specifically discusses large trucks (semis), it is valid for passenger cars.

In addition, if your vehicle is older, you may want to check the link below to the EPA's website where you can put in your "older" car and see what the estimate is using the current estimating method. I had an older car that went from 37 city/46 highway to 32 city/42 highway.

Looks like Nissan USA is under a huge lawsuit from me. After a few drives, and the previous fill-up was a nightmare for me.

Here is what I found out so far:

Driving 60MPH gives me around 520 miles range on a 14.5 gal tank, and an MPG in the high 30s to low 40s. When I drive 70 MPH (most FL highway speed limits) I get around 28 MPG and a gas range in the mid to high 300s. However, if I do a constant 60 MPH, instead of paying $60 per week (2x to the gas station), I only have to pay $30 to $40 one time using an near empty gas tank.

Now, Nissan has been trying to convince me to do the induction service, and we all know where that is going, which is it will never happen when I drive.

Next is, driving 55 MPH and see how many MPGs I get, without pissing off any truckers.

Also, anyone that knows a good attorney that handles lawsuits with auto manufacturers?

And good luck on that!

Gov-mint is shut down now, so Congress ain't functionin'. Oh, I see. Nothun's changed.
