#6. *Trying something new here. I am calculating the cost of the electricity and the gallons of gasoline separately, adding the two then dividing gallonse into it to get the amortized cost of energy per gallon . It looks like this.*
524.5 miles on 6.049 gallons ($12.88) = 86. 7 mpg.
319 EV miles on (69.3 kWhrs x 1.23) = 85.239 kWh x $.08 = $6.82 + $12.88 = $19.70
6.049 gallons + (85,239/32.777) = 2.509 gallons e
2.509 gal e + 6.049 gals = 8.559 gals e.
This increases my apparent cost, but it takes into account the cost of electricity, and thus it is a more accurate accounting for that reason.
319 miles/2.509 = 127 mpg e figured separately.

#5. 9.178 gallons plus 83.5 kWh's/32.77 = 11.7255 gallons e. We had a check engine light so I cleaned the automatic fuel cap and pumping fresh gasoline in the car got the car to reevaluate the vapor recovery system integrity and the light went away.

#4. Local driving, trying to do more EV miles. When we get our 240 volt charger we can do more. We used 58.6 kWh which equals 1.787 gallons plus the 6.285 gallons we pumped = 8.072 gallons.

#2. Gasoline pumped 6.038 gallons costing $12.98. Electricity used 64.4 kWh/32.777 = 1.964 gallonse at $2.62.2 a gallons = $5.15 plus $12.98 = $18.13/8.002 = $2.26 a gallon average. However electricity used to charge the car was 99.16 kWh x $0.08 = $7.93 + $ 12.98 = $20.91/8.002 = $2.613 in this instance. Note:A new low voltage battery was installed on January 6th, 2017 as the OEM battery was defective.

#1. Trip One Read Out. 434.4 miles, 67.2 mpg, 241 EV miles, 52.4 kWH's. 434.4/6.223 = 69.8 MPG. Factoring in electricity 52.4/32.777 = 1.5986 gallons. 6.223 gals + 1.5986 gals = 7.821 gallons. Hence 434.4/7.821 gals = 69.8 MPGe. Electrical cost 52.4 KWH x $0.08 = $16.48. Works out to 3.8 cents per mile with an averaged electrical consumption of 217 watt hours per mile. Note what electric drive in entry #2 does to fuel economy over entry #1. Says it all. Note 52.7 KWH/32.777 = 1.607 gallons e. 6.223 g + 1.607 gals e = 7.83 gallons. 434.4 m/7.83 gals = 55.47 MPGe
