I am not sure who made the reccommend to zero mpg and start again, who ever it was thank you.
My average was 32.4, today I zero and on a 50 mile round trip today my average is 36.5.
Now my problem, is this reliable and why should it make this difference when starting from zero?
If it is correct I am over the moon  David

I feel the only way to ascertain accurate fuel consumption is brim to brim. ( although the computer in the vehicle is fairly accurate.)

we just back from hols in France, and solo MPG over 1372 miles was 41.1 , and towing a 1800 kg single axle caravan over 2028 miles gave an average of 26.8. All fuel purchased was from supermarkets

Vehicle is FL 2 HSE diesel manual which has run perfectly without problem since we bought it in April this year, with 9500 miles on the clock now.

Would I have another ? Without doubt !

Would I go back to D3 with fuel prices going through the roof ? No chance !
