- 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
