get around 650 - 680 miles on a tank, get over 50 mpg on the motorway
i get around 47 to 52 with Tesco diesel. From this week im going to try shell after readig a couple of other threads.
If you havent already sign up for www.petrolprices.com to check out the variance in fuel prices in your area. You can have them email you every day with the best prices too.
well my last tank of £60 of fuel at 115.9 gave me 420 miles, and that was with over half of it tickled on the motorway. i work that out to be aprox 10 gallons thus 42mpg, which is lower than what i expect it to do. My DIS readings (what people here say are higher than actual calculations) are still low, i struggle to get it at 50mpg, i really have to coast down every hill etc.
also my car is completely standard, normal wheels no extra weight etc.
Clough, i see what your trying to say and if it was a rough calculation then i appologise. It does annoy me when people quote their figures with no basis as it confuses people. DIS is often wrong as you say. Whats more frustrating is when people start with the "i get 300 miles from �30" - brilliant do you, thats no use to man nor beast!!!
That idea works in petrol engines but not diesel ones. If you disconnect the MAF, the car will run in limp mode with no power at all, behaves like a non turbo diesel.
