Cool. I used to use a google docs spreadsheet to track mpg, but this gives me easier graphs, lets me update by phone, etc. I also like the community aspect -- having more Clubmans in the database adds value. Alhough I feel bad for dragging the average down!
rasputinj and I are please with our mileage thus far. Have driven an entire week ( ~ 6 days) so far on a tank of gas and haven't hit the 'red' empty tank yet...and we drive a lot!
Not necessarily so, but enough concern that I'd try to eliminate it. To me, it signifies inefficient combustion, and it's accumulation in downstream components (Cat, specifically) that can render early failure. I have not seen any soot accumulation so far, but only have used 4 tanks of gas, 2 at Chevron, 2 at Costco, all premium.
You bought fuel at Costco. Does anyone else use Costco premium in a car OTHER than a MINI? I was told by my MA to beware of gas stations that sell "fake" premium. They just take something and add a cheapo octane booster and sell it as premium. He said to go to the website toptiergas.com and try out the brands they recommended. BTW, what brand of fuel is put in the car when it leaves Cowley? BP, Total or Shell? My car is still on whatever the MINI factory put in it and I've got quite a bit of soot showing on my tailpipe too.
