Whats Your Average MPG?

Whats Your Average MPG?
So I am from the UK and I get my petrol for £1.30/litre. I purchase £20 worth of petrol that gives me 15.3 litres.. I manage to cover 51 miles for that.. Average of 15mpg.
This car is Killing me when I have a friend with a Renault Megane F1 300bhp getting around 25/30mpg?
What's your MPG?

In the UK do they disclose mpg values for cars? Or do you just buy a car and take your chances?
What other comparisons between you and your friend are making life miserable?

OP,
Your comparisons, calculations, and units of measure are all over the place, and your sampling range is very limited. If your pumps are in litres, then calculate and compare in those units. And to calculate, FILL the tank, drive until you need to fill it again, reFILL the tank, and use THAT volume of fuel over the distance driven to calculate your consumption rates and comparisons. Sampling your fuel consumption over the course of only 50 miles is not enough for a valid assessment, and calculating fuel consumption based on the fuel gauge or other approximations can be very inaccurate.
I only compare my fuel consumption to what is normal and healthy for the RX-8, as an assessment of its normal running quality and condition. For instance, 16-23 mpg could be considered a normal range of consumption for the RX-8, depending on driving conditions and habits. If you notice the consumption falling lower than your normal range, it could be indicative of an issue that needs attention. It is pointless to compare the fuel consumption of a Wankel rotary-engined car to conventional piston-engined cars, as the designs and dynamics are quite different. Surely, you were informed about this before you decided to buy one, correct?

Yeah, his methodology maybe isn't the very best... But the results certainly aren't atypical. I get 16/22 mpg (city/hwy).
Besides, your friend's Renault Megane F1 is still an ugly Renault. If you must compare your car to his, to base your happiness with your vehicle, at least do a total comparison.
This is a phenomenal point.

OP, You'll probably find more numbers by search the site for this. It's been discussed many times before. I've lost count of how many threads there are on the subject.
FWIW, i don't check mine. I don't even count how many days between fill ups, or how much money i spend when i do fill up.

The Michigan "WANKEL"
The average MPG for my 2009 RX-8 since the day I bought it on March 18, 2009 is 19.1 mpg. I drive it to work 85 miles away fairly often in summer, though, so that bumps up my average. When I'm just having fun I tend to get between 12 and 16 mpg.

The cost difference between my 8's mileage and my wife's car's mileage means that I get about 121 miles of fun for the same cost as my wife going to a movie (without going to concessions).
Or about 857 miles for about the same cost as a new pair of her shoes.
I think I'm getting a better bargain.

That is how I am thinking about it as well. It's entertaining and one of my hobbies just like my motorcycle and my bicycles...hobbies cost money. I am new to this car but in the weeks I have had it I seem to be averaging about 15 litres per 100 km.

Mileage
I drive 80 miles to work and back 5 days a week. I have a lead foot and go 80 to 90 if traffic permits. I also get in a lot of traffic jams on the way. My son complains that I am "always accelerating".
I get a very consistent 19.5 MPG.

MPG is irrelevant (the way I drive my 8 is 18+ MPG during warmup, 12-15 MPG after) if MPG is important you bought the wrong car. I measure my cars/bikes in SMP (smiles per mile)

Comparing MPG from UK to USA is not relative because the gallons are different sizes not sure the exact size but a UK gallon is just under 5 litres and a USA gallon is about 3.8.
Therefore 25 MPG in the UK is the same as 19 MPG in the UK.
Then the fuel is better Octane rate in the UK at 95 - 100 whereas the USA is 87 - 93.
The same car will get much better MPG in the UK than the USA because of better fuel and bigger gallons.

Mpg
Gas mileage isn't irrelevant if you drive 100 miles / day unless you are a kid that only has a car as an expense. I suggest if you only get 16 mpg something is wrong with either your car or your head.
I am really surprised how quick people on here are to slam others. This place must be populated by children.
