Diesels 2WD

Diesel Syncros

SyncroAnd101: Expedition Camper (Syncros) over approx. 5,000 miles from GBto Southern Morocco and back, off-road, sand, snow, rocky roads part way, part high altitide (Atlas Mountains)

1.9 mTdi, off-road tyres, high-top, fully loaded, roof rack etc. + 2 people == 30.93 mpg.


Peasant: 1.6TD Average of 8.5l/100 km on short-ish country road runs (33mpg) Around 8 l/100km on longer runs (35 mpg)


SyncroG: 1.9TD Down to around 30mpg nailing it up and down the hills here, on a motorway run it's better, sometimes high 30's. Gets a lot more wind and engine noise once you go over 55 so I'd imagine it'll drink badly soon after 60mph.


Slobbo:

With odo readings adjusted +10% for larger wheels and tyres MPG DieselTdi Slobbo 02.jpg


HarryMann: 1.9TD Syncro Doka 15" Machos (knobbly mud tyres); overfuelled a bit and boosting to about 14 psi - Accurate speedo, odo error about -2%..

Lots of off-road, also lots of problems, manifolds coming loose, blocked filter changed at 2650 miles, turbo probs etc., some towing towards 5,000 mile mark.. also, most long-dist cruising usually nearer 70 than 60, sometimes 75. Have towed heavy trailers, have carried 3,000 lbs + in back, crawled for miles through lanes as well as sat on French motorways in high heat.


NB. Actual points plotted are where a full fill back to brimming is made, intermediate fills included in next brim, so no guesswork really, other than exact brim-point slight variance, which soon becomes insignificant after a few thousand miles. Note that the curve to use to judge mpg 'trends' is a rolling mean of last 3 or 4 fill-to-fill figures (yellow curve). Pink is actual MPG to date, so right hand end of line is what it's done since recordings started. Blue is brim-to brim, so gives you a good idea how misleading even a whole tank brim-to-brim can be.

So I have driven about 6,000 miles since starting this record and she has done EXACTLY 22.98 (uncorrected) and 23.44 mpg (corrected by 2%) Good or bad, there is no argument using this method. She can do 27 and also worse than 20 when going is tough, loaded or needs an airfilter change. I can also see clearly the results of tuning, adjustments, improvements and heavy footed driving! I should also know quickly when she is not running right. Also if someone is siphoning my fuel :)

Petrol 2WD

Petrol Syncro

Mudlark: 2.1 Autosleeper down to Corsica and back, 2+ 2 on board plys kit.

trip in 2003 without prop trip in 2004 with new VC and prop

Both similar trips over similar routes brimmed to brimmed and recorded fill by fill producing:

2003: 2990 Miles 144.51 gallons £500.83 20.69mpg

2004: 2744 Miles 131.7 gallons £460.10 20.83mpg


Syncrosimon:2.1 16" Camper to Corsica and back, 2+2 and loads of kit.

trip in 2008 with de-coupler and new VW DJ engine running 3/4 on 98 octane 1/4 95.

4102km, used 484 litres of un-leaded. To my calculation that is 24mpg.

This was mainly flat out or near flat out running at 120kmh then on the peages.


akira28: 2.1 DJ Syncro

19 town & country roads 22 on the motorway normally around a steady 60MPH.

Average over the last 7 years is 20.38mpg


Toomanytoys: 1.9 DG Syncro, 20 ish local stuff.. 24 on a run at 60-70

..lee... My 2.1 does max 23mpg motorway @ 70 ish. empty.

Fully loaded me, mandy, 2 kids and the dog got 19mpg over i think about 700 miles.

MPG Spreadsheet (Download)

XL2003 MPG Spreadsheet

In Firefox please choose Save As and save to your local disk (e.g. C:\Temp) before using

In Internet Explorer, if the spreadsheet just opens, then use the worskbook File.. Save As menu item.

e.g. Don't use the spreadsheet on-line

First select the cells with dummy data, then Clear Contents, ready for your first row (initial brim) which of course won't produce any figures until your next fillup. If you don't brim, just add that figure(litres) to the next time when you do brim

NB. Don't forget to hit the File... Save button everytime you enter a new row of fuelling data

The spreadhseet contains a data sheet and a chart. The datasheet is protected (no password) to prevent inadvertant entry of data into formula cells. Yellow cells are for data entry, one row at a time.

A mileometer factor can be entered into the datasheet to adjust for tyres (no cheating! :)

The chart should be left alone unless you are XL power/developer user level, though the title can be changed There is a Macro in Tools... Macros for saving the chart as .jpg image to C:\temp (will overwrite any existing so rename if reqd. immediately). Altenrnately you can double-click the chart to save it as a jpeg image to your c:\temp directory

PM HarryMann for more detailed instructions (I will write a usage/FAQ page and include it in the workbook, some time soon)
