Actually I'm using my Micra Equation for Chinese Takeaway delivery, as this little Micra is used quite vigrously so I keep calculating the fuel economy of it to monitor my income.
For most of the time I use Shell (coz is more convenient for me) but I found that the fuel economy of the car keep dropping using Shell in this few weeks, dropping from 39mpg to 34mpg, which means I need to pay roughly extra 2p for each mile I traveled, even worse than my 1.6 Tigra...
The micra is just full serviced for less than a month with every filter and spark plug (NGK) changed,
and once I switched to ASDA the fuel economy rise back to more acceptable 38mpg.
So I just guess, the fuel economy drops maybe related to the quality of the fuel, my coleague who drives an EK claimed that he is suffering the same problem...
But yesterday I tried to put some Redex mixing with Shell and it seems OK... but the calculation result cannot be figure out before the next full tank of fuel...
Did anybody in here having the same trouble recently?
Also, which brand of fuel you guys think is the best suit for Micra (Y)?
My average currently (City, extreme use):
Tesco: 42mpg (but the petrol station is quite far away from my home so I seldom use it)
Sainsbury: 36mpg
Texaco: 38mpg (and it's expensive)
Regent: 37mpg
ASDA: 38mpg
Shell: 42.5(Motorway) 39mpg drops to 34mpg
Suprisingly Tesco should be the best currently... Any tots?
