Interesting comments on MPG (or l/km) – it’s one of the parameters I monitor and plot total average MPG – I find a plot of MPG on each fill goes up and down depending upon how/where you have driven during that fill. This did help me identify a problem occurring on a petrol Audi I had – the gradual decrease in average MPG at around point 100 can be seen. Solved the issue (slightly leaking injector seal from memory) and average MPG crept back up and stayed pretty level until sold (at 150,758 miles). You can also see the increase in MPG as the engine loosened up running in – with stability reached after about 25,000 miles.
Doing the same for the Morgan +4 (but only have data for first 1593 miles – average now 38.6 MPG but, as engine loosens up can see average MPG increasing from an initial 34.5 MPG. Reckon it will level out at over 40.
So while I agree driving the Morgan is more entertaining!
- I find average MPG a useful parameter to help spot things happening.
