my FR is 11000 miles old and has suddenly developed more power and better mpg
Im not an economy freak and even tho its remapped, I always got 38-39 mpg on an average over a few tanks. It has been running on local supermarket diesel but always with Millers additive.
Now, after switching to standard BP/Shell fuel (not the 'ultimate' or 'v-power') it seems much sharper and faster thru the gears. Also average mpg has gone to 42-43 over the last 500 miles. I also stopped tanking up, now I just stick in £20 a time which logically enough means Im no longer carrying the weight of an extra passenger.
Just wondered if anyone else has found this difference with city diesel vs 'proper' stuff?
Am I just being sad, and maybe the car has just loosened up after putting some miles on
Perhaps its just the cold weather making it burn better????????
