| Just add petrol and diesel MPG figures here please, LPG figures go in the LPG section.
| | We have a 1.9DG Viking camper 1986 with 40,000 miles on the clock which on a long motorway run during summer has been known to return 29MPG...........If used daily during the urban cycle you can expect anything from 18-22 MPG. |

| '''Clive's Debunking of accurate MPG figures''' | | Having the vehicle loaded doesn't appear to make any difference with these fuel figures.........\ |
| None of the figures are correct for your mpg, because the amount of fuel used over such a short distance cannot be measured accurately, whatever anyone tells you - honest!.
| |
| Plus there will inaccuracies in the true mileage recorded, and whilst some of these may cancel out, equally they may not, and add exagerrating any errors.

| 162 miles/ 4.033 galls = 40.165 mpg

| 4.033 galls = 32.264 pints

| If you did this by 'brimming it' (at the same garage parked at the same pump, at the same temperature) you could easily be a pint out, probably more. That's 3% for starters, so anywhere from 38.9 to 41.4 mpg - if you tried very hard to fill exactly to the same point. So even with such a small error as a pint, one will be saying - my car does 40 mpg, and it'll be lucky to do 39, another saying 38 when it could be doing 40 or more. In practice errors are ''larger'' than this.
| | 88 1.9dg Reimo hi-top westy gassed w/stock tire. 17-19mpg on 2 mile urban commute, 22.1-24.8mpg @ 40-55mph on holiday on holiday in France, 19-22mpg @ 55-65mph. Petrol and gas mileages are too close to same to tell without doing some real testing. Gas fills will vary up to 8 ltr from 55 to 66 liter when completely empty due to station pressure and temperature, so mpg will vary dramatically. One half tank fill was 13.8mpg while another was 26.7mpg. |

| So if you didn't try hard to re-brim exactly as before nor (at the same garage parked at the same pump, at the same temperature), then we're really pissing in the wind (Smilie)
| | Weight doesn't seem to matter on highway miles, but does dramatically affect short runs. |

| Brim it accurately, and finally at the same pump after a dozen runs like that, logging all the fuel in between, and that would be a good all-round figure - for that journey (and only that journey, with that driver, at that time, and that season) - Winter mpg can be 5-10% less good than summer.
| | Using half throttle or less and NEVER full throttle makes a huge difference! One fast start up to 30mph will knock 2mpg off of a 100 mile run of 22mpg. Same for stepping down on it and passing or climbing hills. Have had 3 vehicles with onboard computers to test it on. |

| Sorry, rant over, just seen it all and heard it all. The best and incontrovertible way is to log all the fuel you ever fill up with in an Excel spreadsheet and plot the running-mean mpg's - very useful for spotting when the engine's going off, tyre pressures are low, or your boots are full of lead Wink - but only anoraks or obsessives do that (which is how I know you didn't really mean - exactly )

| '''Fuel Guage''' dont get caught out, the gauge is non linear, usually. Full to half is more like 3 quarters of a tank half to empty drops like a stone. this may be due to older wiring tank senders etc, but I have noticed a few people mention it.

| Post your figures here:
| |
| | |
| Bob - 1.9 petrol hightop camper = 20-23MPG
| |
| | |
| Matt - 1.9 petrol poptop, fully loaded, and I mean fully, inc bike rack and 5 passengers, 14 day road trip = 18 to 20 mpg on LPG
| |
| | |
| Harry - Diesel 1.9TD (AAZ) Syncro Doka (wiv 15" wheels, knobbly tyres, and running 12 psi boost) = circa 23 mpg
| |
| | |
| CJ (quote) - If anyone says they're getting more than 20mpg from a 2.1 WBX, be very circumspect about their measurememts or calculations
| |
| | |
| kevtherev - 18-25......depends how heavy your foot is, reserve ....i.e on red is...2 gallons
