MPG how do you work it against fuel

[CHIMV8]

Been asked to try a product that will help fuel economy and engine efficiency.

Need to workout current mpg before fitting the product,can you explain the best way to do this please.

fill you car up do 100 miles fill it up again see how many litre you used and there are 4.54 litre to a gallon divide how many litres by 4.54 then you`ll cry how bad it is i guess a 4litre would be about 25 to 28 ish

Too late, if it is the same one it did work and has already been tested:

TVR 14CUX fuel restrictor

Do they make a version for after market ecu's?

Simple:

1) Fill the car, brimming the tank

2) Zero you trip meter before you leave the petrol station

3) Do at least 150 miles of mixed driving

4) Return to the petrol station & brim the tank again

5) Note the quantity of fuel needed to brim the tank recorded on the fuel pump

6) Note the miles recorded on your trip meter

You can then simply calculate the miles per litre.

Or to get the MPG:

1) Divide the litres figure by 4.54609188 to get the imperial gallon figure

2) Take the miles on your tip meter & divide by your imperial gallon figure to get the MPG

Example:

1) Miles on trip meter shows 156 miles

2) Fuel pump shows 28.84 litres delivered to brim the tank

3) 28.84 litres divided by 4.54609188 = 6.3439106 imperial gallons

4) 156 miles divided by 6.3439106 imperial gallons = 24.59 MPG

You don`t have to be like that ! where have you been? not seen you at the meets...Those badges have fell off only joking ..but seriously since the new Gen111 injectors and re map from dexterjio gained me 8mpg..Combination of the correct fueling and these new injectors.. we all know they guzzle in traffic and a heavy right foot..!


327miles 50litres = 29.73mpg

And you are quite sure its still making the same power?????
A well known mapper hints that the bosch injectors can lose some top end power......


And why keep on about 340bhp and 30mpg, when you get 30 mpg , you are probably only using 75bhp of it !!!

Time to get a Prius Daz.....

will let u know once tried

I once measred MPG on a motorway journey up to my inlwas in Leeds at 24MPG, which I thought was pretty good (I do have a heavy right foot), and I also measured the MPG during a track day, which was, assuming accuracy on the filling, 9.6 MPG, now I really can't see the value of measuring, it does what it does, and I love driving it. What would I do with the information, sell it? that's never going to happen, cry? I have to many other things to cry about. Why bother, it's a gas guzzler, face it.
