continued using pulse and glide method of driving. Cutting the engine on steep hills did save a bit more fuel, but discontinued using that particular method because 1) lots of hassle for the savings 2) safety reasons 3) bump starting the car could lead to exhaust CAT issues"

2016-03-08 287.1 6.56 $0.8 43.77 "about 16 trips of 17 miles too and from work. as we have had some very cold mornings, I as expecting to see a worse mpg return. the odo is 3% optimistic, which I never correct for."

most journeys where 17 miles."
2016-03-30 384 8.87 $0.8 43.29 "stuck in traffic for an hour- reduced my MPG.
new LPG tank fitted, so the next fill will be more accurate as the tank would be 100% purged of air"
2016-04-15 464 11.04 $0.8 42.03 "Mileage mostly made up out of 17-mile work commute trips. For a week there was an additional fuel cost due to a road-works detour.

2016-04-26 899.8 20.63 $0.8 43.62 "Was hoping for a better fuel return as 600 miles was motorway driving. Going to replace the front tyres as one of them is unbalanced (possibly a pothole), this may have reduced the MPG slightly? Trying to drive at engine load of 32-36%, 54MPH and usually behind a truck on the motorway, which at times was giving me up to 67MPG"
2016-05-11 466.8 11 $0.8 42.44 "Mileage mostly made up out of 17-mile work commute trips. Being a dual fuel, car done 1380 miles with 5l of petrol (this being part of the dual fuel system). Also being dual fuel, I cant incorporate this additional fuel in the above data- hence me now writing up this additional info as and when I top up with petrol."

Per 1000 miles travelled breaks down to 26 miles of petrol on engine start-ups (@27MPG). This equates to approx. 0.45 miles of engine running on petrol before switching over to LPG. The remaining 974 miles on LPG equals a true 48.5 MPG, adjusting for odometer inaccuracies. units for UK."
2016-06-26 351.9 8.09 $0.8 43.5 "mixed motorway and 17m commute trips. car left standing so was occasionally taken out for short runs to keep the battery topped up.
a new garage was used for fuel top-up, so it was nice to see the same MPG fuel result"

2016-10-02 458.8 10.92 $0.8 42.01 "I had some A:B:A fuel log testing going on in this tank of fuel. drove more harsh, plus took known road trips which were less economical for the car.
Conclusion: being an extreme ecomodder does save fuel, savings between 1 to 7% cost"
2016-11-21 520 12.68 $0.8 41.01 "Unfortunately, car has been running poorly so been using more petrol and less LPG- this will obscure the final MPG results. I am hoping AFTER my next tank fill these problems would have been sorted out (remap of LPG ECU, spark plugs, filters ect)."
2017-02-09 170.2 3.58 47.54 "petrol top-up (not LPG). Had problems with the CAT and coil pack, been resolved now. Hoping for best ever fuel economy from hereon in."
