    What's the most fuel you have put into your ZHP?

    Out of curiosity, what is the most gallons of fuel you have put into your ZHP at one time when refueling? I know the user manual says the gas tank holds 16.6gal with 2.1gal of reserve.

    I have never managed to get anything near that even when I have been driving with "---" on the computer.

    Just last month I thought I was going to run out of gas and when I filled up at Costco it was still only 16.18 gallons. And this was driving around for probably 10 miles with "---" on the trip computer.

    What is the most you recall pumping into your car? Has anyone actually filled up with 16.6 gallons?

    Also is the 2.1gal reserve, is this in addition to the 16.6 gallons? or just how much is left in the tank when the "low fuel" light comes on? My guess is it is the latter as I can't believe you could put 18.7 gal into the car (but I would be happy to be corrected).

    I average 23 mpg with my ZHP (city/hwy combined) so if there is really was around 1/2 gal left when I am sweating bullets, that is still ANOTHER 10 miles I could go before actually running out.

    Just curious how far others have pushed it.

    Was about to post literally the same thing lol. The little gas station I normally hit in North Texas had closed and I didn't know. It was a looooot of hypermiling to get to Amarillo, lol.

    So far sounds like 16.6 gal is the full size of the tank since the most anyone has put in is 16.5 gal.

    That means the 2.1 gal "reserve" is probably when the light goes on. Otherwise, SOMEONE would have remembered if they put in 17+ gal.

    What's the most fuel you have put into your ZHP?

    I just checked 400 tanks and found one at 17,789 and one at 18,145 gallons. The Excel sheet seamed off and when I checked the hard copy it was the same.

    Iíve been pretty anal about this log and it accuracy but, with 400 tanks there could be mistakes.

    I think I recall putting in 17.1 but I need to verify before staking that claim.
