240 General: fuel consumption

[25 240]

I have a 1988 40 GL manual and £20 would get me 140 miles if I drove very steady (always keeping revs low) . . . . not the cheapest I've owned but for the size of the car and engine, it's acceptable IMO

anyone know the capacity of the fuel tank? I've got a 1985 dl.

Changing the gearing has no effect on the speedometer or mileometer, unless you have an earlier car with a mechanical speedo connection to the gearbox.

The electronic sensor picks up crown wheel rotation, which is the same as axle.

60l.

I've done 380 (genuine*) miles on a tank

* Trip counter said 402 miles

I'm finding that new Shell Fuelsave petrol has upped my mpg to 36-38 on long motorway runs on my 240GL. Also from recent MOT's on my 1988 240 and 1996 Jag XJ6 emissions have been noticeably reduced on the previous years tests. I had been running on Vpower since it came in but the lower octane fuelsave if anything runs better.

Roughly 1.4 metric tonnes / 1400kg / 3000lbs depending on spec and saloon/estate. Not as heavy as you'd think, especially compared to modern cars (although they were definitely a heavyweight at the time).

Bear in mind, axeman, you may well have one of the few vehicles ever made that's LESS aerodynamic than a volvo estate!

oh well what can i say? mine weighs in at around 1800kg, but i can still hope. things will have to be better than the urban 18mpg and 22mpg on a run, (2.1 vw flat 4. 95bhp engine)

240 GLT 2.3 Manual, just completed 2 runs this week on Shell Vpower.

243 miles 2 up plus 3 Greyhounds (about 100 kilos) plus suitcase satnav speed med to high 70's got 29.20 mpg.

255 miles 2 up higher speed low 80's got 28.56 mpg.

I have run other cars on ordinary and then Vpower and reckon I get a smoother run and a bit better economy to offset the higher price.

Interestingly my guage reads 3 quarters full when actually full and when halfway through the red zone I estimate 4 gallons left. Still getting used to it.

Wonder what mpg I would get on LPG?

LPG gives the equivalent of 38mpg from 27mpg petrol on a B200E 245
Dutch Groot system converted 10 years ago. Starts and runs on gas.
