What's the longest range you have driven on a tankful?

It's funny that I was nicknamed Captain Slow at the Road Atlanta racetrack before Top Gear TV even existed.

My DB7 i6 returns between 300 & 325 miles on a tankful, so between 23 - 26mpg

I only drive it on long runs really which helps

My V8 has a 25 UK gallon tank and often achieves 350+ miles on a tank at 15-17 MPG average. That's Calais to Le Mans with some to spare. Track days is more like 8 mpg.

Umm, the V8v has a 78 liter fuel tank (useable, max capacity is 80 liter). That translates to ~17 Imperial gallons or 20.6 US gallons. Do you have a different tank in your car?

The most I have been able to put into the tank at the pump is 16.6 gallons and the trip computer was stating there were 30 miles left to an empty tank. I don't know where the remaining 4 gallons go, unless it is estimating that I will get 7.5 mpg for the remaining fuel. I think most trip computers "lie" in order to give you a cushion of a couple of gallons worth of cruising range beyond the reported "empty tank".

My V8 was made in 1977

301 miles using 51 litres = 26.6mpg is the highest I've got. Leeds to Silverstone and back so all motorway miles and heavy traffic so just steady driving all the way.

Can't be bothered to work out how many miles to an empty tank for the above 51 litres.

Wow, that must be getting on for £150 to fill your tank. Thats really getting noticeable

V8V on French Autoroute I was averaging 25MPG and overall for my European trip 22.5MPG. I travelled 350miles between stops, but was getting very nervous......

V8V on track taking people on rides 120miles from full to empty (i.e --- showing on miles to empty)

V12V I try very hard not to look, I just know that £50 only takes me around 100miles

Those clever folk who plug a diagnostic reader device into the car's comms port and have variables bluetooth'd to handheld device could try looking at 'VCAN_FUELLEVELPUMP'. This output is usable fuel in litres pump side.

I can vouch it is reliable down to zero - on many occasions......

This takes away the variability of range calculated on dasboard display which depends on prior average fuel consumption.

Welsh hooning with Yeti saw a personal best of 11.6mpg

Run upto Jockland was 25mpg

Average about 18mpg

I think of it in Smiles per Gallon, that way I got lots
