Thanks Paul, appreciated
So I'm back from a trip to the mountains of Vermont. There was alot of hills and long climbing slopes for miles. I remember once I was climbing for maybe 4 miles at almost 3000 rpms at 65mph. I watched the DTE drop 20 miles as the engine MPG number (RAFE) was dropping fast. When I got home tonight I found out that the number has dropped from 56.9 to 44.5 now. If I fill the tank I should see 623 mile range, still above Ford EPA estimated for this car and after a 500+ mile trip on the highway to Vermont and back. See pictures below.
You can also see I used up just about ALL the gas in this car. Having a HVB really helps to calm the gas range anxiety, if you're running low on gas at least you have the battery to get you home. Made it with 7 miles range of gas left, and 2 miles of HVB. When I checked the ET screen, it showed about 12 to 13 on the fuel gage, which, when full is 1004 if I recall correctly. So if my math is correct, 12.5/1004 x 14 gallons = 0.174 gallons of gas remaining or 22.3 oz. Not sure if its real or not, but that's what the car's computer thinks.
My buddy Larry who was following me up to Vermont and back in his Ford Lightening truck filled up in Derry, NH. Went to Troy, VT and back down to Millis, MA before getting gas. To fill up his truck it cost $75 as he's got a 25 gallon tank, put in 23.25 gallons of super. I went up with almost 3/4 tank of fuel, drive over 510 miles on that including 15.3kwh of battery or close to 3 full charges. I didn't get any gas at that station tonight, it was more expensive than normal, and I figured I had enough battery to make it home.
MPG for the trip at 55.7, pretty decent considering all the mountain climbing.
I left the car unplugged to cool the battery down tonight, and didn't burn the entire battery many times on this trip as I didn't want to climb mountains with it, even though I knew I was going to be able to recharge at my next stop, I just used more gas and less battery as the battery is more important than the gas. Sacrifice a few miles per gallon performance but worth it to protect the battery.
