MPG Indicator

Sure....

An inexpensive calculator.

My 2006 Solara has one. It does a few things. 1. AVG MPG 2. Actual MPG(While driving you get a real time reading of how many gallons per mile you're consuming. Don't know how accurate it is 3. AVG MPH. 4. Driving Range(Miles left before you run out of gas). 5. ETZ - haven't looked at that one yet.. :) . So I fugure you should be able to get one.- Good luck

I've seen aftermarket trip computers that have instantaneous and average MPG readouts but they are not easy to install for someone without pretty thorough knowledge of automotive systems. You have to install a magnet and reluctor on the driveshaft, calibrate distance for driveshaft revolutions, install fuel flow sensors in the fuel line, and then wire everything up.

The best way to calculate MPG is to record distance traveled between fillups and use a calculator.

Theoretically, this could be very accurate. All it requires is a simple fuel flow rate vs. ground speed calculation.

If Toyota chose to make it accurate may be up for discussion.

Or the back of an envelope or shopping list. simple divide the mileage driven by the number of gallons on your fillup.

200 miles divided by 10 gallons means you've gotten 20 miles per gallon. But you knew that.

They have one at thinkgeek.com that plugs into the OBD-II computer connection, sticks on the dash, and gives you instantaneous and average MPG, as well as a lot of arcana like temperature and pressure sensor readings from around the car. Isn't cheap, somewhere around $150.

Of course, if you're asking about a 1980 vehicle that isn't even EFI (let alone OBD-II compliant) you're out of luck with that one...

But that's not Kewl! I use the 'computers' in my Chryslers all the time to 'modify' my driving.

I was doing 55 in a 40 one time on a back road and saw the blues. The cop asked if I knew how fast I was going. Um, I have an idea. He asked me if I was being a wise guy. I said, no, pointed to the readout and said, at this time of the day, on a clear road, THAT'S the meter I go by. I was getting

45 MPG with my LHS!!! He let me go, with the words...Look at the OTHER meter more often!

It gives you tarot cards?

Temperature and pressure can be very meaningful for a serious MPG examination.

Not that I know of.

You can easily do the math though.

1 Start a log book 2 Fill the tank, write the mileage or reset the Trip Meter 3 Drain the tank. 4 Fill the tank, write the mileage or note the Trip Meter and the amount of gas it takes to fill the tank. 5 Divide the miles (subtract the first log entry from the second) by the number of gallons (You can ease this process by utelizing the Trip Meter) 6 Reset the Trip Meter and repeat from 3

Over time, you will be able to see that your car delivers consistant feul economy for the consistant driving that you do. If your mileage goes in the dumper, then you have to decide if you did more stop-n-go driving that tank of gas, or if your mileage increases then you have to recall if you took a long trip on the freeway.
