Since i had the sei, i always had the theory that fiats liked running on shell petrol better than anything else, and that of all the petrol stations ive visited, it was always tesco petrol that was useless. so being an anorak, i thought id do a little experiment..
when i had the cinq, it always ran slightly sweeter on shell 95 than anything else, but no difference in mpg between fuels. then i had the focus. That didnt really seem to bother what it was running on, but seemed to get fractionaly better mpg from shell, but the sei was where i really noticed the biggest difference. on tesco fuel, the car felt sluggish and i was struggling to break 30mpg by my calculations, where as after a tank of shell, the car felt much more livley and i was getting about an extra 40-60 miles a tank!, makes you wonder how poor quality tesco fuel is :thumb_down:
anyway with the thirstier punto hgt , sat nav its trip computer and an empty private road, i thought i'd test my theory properly over 2 full tanks of tesco fuel and 2 full tanks of shell fuel at as near the same average speed as possible, the results were incredible! :smart:
Over 2 tanks of tesco's 95 ron
Cost, 83.9 ppl
Average speed, 21.6 mph
Average mpg, 24.5 mpg
0-60 time recorded, 8.6 seconds according to sat nav
and for shell
Cost, 82.9ppl
Average speed, 21.9mph
Average mpg, 27.1 mpg
0-60 time recorded, 7.9 seconds according to sat nav
the conclusion..... tesco's petrol is **** poor.... i wonder who supplies it to them......
has anyone else noticed such a difference between fuels?
