Fuel costs and mpg
Discussion
335i - £60 gets me 350-375 miles. So about 31mpg. This is pretty much what the trip reports back too.
Can't complain as that is loads better than my old tfsi leon and that had 1 litre, 2 cylinders, 1 turbo and a good amount of weight less than the BMW! Same driving style and journey types too.

I don't understand why you'd try to track economy with things like "Oh, it costs about £40 to fill and I get 360 miles"... That's so inaccurate it could be 20% out either way!
Run it to as empty as you can, fill it up and keep the receipt, check how many miles since you last filled up and then you have your answer.
FWIW I'm averaging 36mpg in my Clio at the moment, which is +2mpg on the combined figure. Pretty good considering it gets a good workout for half my usual journey.

I find that our diesels are more consistent with MPG, they get almost the same MPG no matter how you drive them while our petrol MPG figures are all over the place depending who is driving, when , what the weather is , even down to what is playing on the radio.
Somewhat odd list of cars because I look after (and usually fuel most of the family cars)
Ford Ranger doublecab pickup holds 60 litres of diesel. Mileage varies a bit as it's a workhorse, 32-34mpg empty, 30-32 loaded, 26-28 pulling a heavy trailer
MX5 (MK1 1.8) Holds 45 litres petrol. Have managed 40mpg when trying hard to get home an a near empty tank more like about 32 on average and 22-24 when playing.
Original mini clubman 1100cc with huge SU carb. Has twin tanks so holds about 70litres. MPG varies hugely, have managed 68mpg but have also managed 17mpg.
Golf GTTDI. Holds 60 litres Diesel. Never goes below 50mpg no matter what, can get 56-58 if you're careful.
Passat TDI 1.9 Holds 60 litres diesel. Was hugely underpowered and got 42 mpg under load and 52mpg if taking it easy. Got it chipped and now it vairies between 52 and 56 mpg.
Golf 1.6FSI Holds 60 litres petrol. Varies between 28MPG with my son driving and 42 with my wife.
Fiesta 1.25, Holds 42 Litres petrol. Varies between 35 MPG and 45 MPG depending whether my daughter is going to work or coming home.
Fiesta 1.4 TDCI, Holds 42 litres diesel. Runabout, used by everyone , seems to get 64-64 MPG no matter what.
Type 2 VW camper, holds 60 litres petrol. Varies between 20 and 32 MPG dependant of whether in snail mode or not.

Auris Hybrid (estate).
Cost to fill, max £45 although I very rarely run it this low. Range per tank, could probably get 500 miles if I'm brave enough, but the fuel warning light comes on with about 5 litres left.
Overall real (calculated) average over 40,000 miles is 52 mpg, or about 5-6 mpg below the estimate on the car's display.
Over 20 years or so of logging my fuel use in various cars, I've come to the conclusion that the trip computer in cars is inaccurate, ranging from optimistic to 'what is it smoking!'. Best was a Polo at about 2 mpg over, worst a Volvo at about 14 mpg over.
That being said, even doing a single tank fill to check isn't particularly accurate, it's far better to do it over say 10 tanks and work out the overall average.

My e60 535d with swirl flaps and DPF removed and chipped takes £80.00 to brim and does 28mpg consistantly pump to pump. The OBC however says that it's doing 24.7mpg so that's slightly off.
Not set to US gallons is it?rainmakerraw said:
I've generally found if you take the three NEDC figures (urban, extra-urban, combined) and then lose the extra-urban figure, you can make use of them. As a general rule, the urban figure will be what you average over a tank and the combined figure will be what you can hit 'on a run'. It's only a guideline but it's better than the so-called combined figure for real world usage.
I figure on about 85% of "Extra Urban" is realistic for "on a run" and 85% of avg for normal use with 85% of "urban" for heavy town use. All cars will vary however depending on how much the manufacturer has gamed the tests...For example mine claimed is:
Urban mpg 20.8 mpg
Extra Urban mpg 41.5 mpg
Average mpg 30.4 mpg
I get 34-36mpg on a run and 24-26mpg day to day dropping to 16-18mpg in stop/start heavy traffic. That's driving normally though, I can better them but it's hard work and means accelerating like a granny.
To answer the original question, about £65 to fill and that'll get me between 350 to 550 miles depending on if motorway runs or normal.
