(Table explanation)

Table Explanation

The data table shows all tabulated values with many extra data columns.

The columns are:
Date
- the date of this fill of diesel
Miles
- the odometer total mileage reading
Litres
- the diesel pump reading of litres put into the tank
£
- the cost, usually in Pounds Sterling
Rsv at
- total miles when first noticed (negative: miles since reserve noted)
Comment
- anything that may be informative
MPL
- calculated miles per litre for this fill
MPG
- calculated miles per (UK) gallon for this fill (4.54609188 litres i a gallon)
OMpg
- the average miles per gallon since new
ΔMls
("delta miles")
- miles since the previous fill
Roll 3
- the average MPG for the last three fills
RsvRng
- the calculated miles until reserve indication expected
Rng
- the calculated range for the whole tank of fuel
M/D
- average miles per day since the previous fill (or fills if more than onefill in one day)
AvM/D
- average miles per day since new
rsv err%
- difference between actual reserve and calculated reserve
Geom av
- pseudo-geometric average MPG, calculated as 0.25 of the latest mpg plus 0.75 of the previous value.
Ds/fill
- number of days since the previous fill
Total days
- total number of days since new
GeoMpD
- geometric average miles per day (calculated as for geometric average MPG
Miles/Year
- average miles per year since new
M to rsv
- calculated miles left until reserve should be indicated
p/mile
- calculated cost per mile
