Re: October MPG Averages

Surely Someone bought gas this month!!

Here's a fillup after half expressway/half street driving:

Tank Miles: 344.9
Total Miles: 1132
Tank MPG: 44.6
Avg Temp: 70s
Price of Tank: $15
Price per Gal: $1.93

I will post two more tanks separately.

 

Re: October MPG Averages

This tank was all interstate from Chicago to St. Louis, cruise around 72 mph. Tires all 35 psi

Tank Miles: 314.4
Total Miles: 1446
Tank MPG: 42.1
Avg Temp: 70s
Price of Tank: $15
Price per Gal: $1.97 (a bit lower in MO than IL)

At this point I changed the tire pressure to John-like levels and things improved.

 

Re: October MPG Averages

This was also all interstate from St. Louis to Chicago. Two things were different from the previous tank:

Tailwind instead of headwind :wink:
Tire pressure finally increased to 42 front, 40 rear as discussed elsewhere

Tank Miles: 353.8
Total Miles: 1800
Tank MPG: 49.6 (much improved!)
Lifetime MPG: 46.97
Avg Temp: 60s
Price of Tank: $15
Price per Gal: $2.02

I don't think I'll get to fill it again this month.

I did, Nov. 2 with little or no November driving.
Tire pressure decreased to 40 front, 38 rear. Half highway and half residential area.
Tank Miles: 419.6
Total Miles: 2220
Tank MPG: 46.0
Lifetime MPG: 46.80
Avg Temp: 60s

 

1 block flashing at 831kms.
Filled up today.
Tank kms ........ 857
Overall kms.....6200
Rate .............$1.045 / Litre
Cost .............$48-53
Litres ............ 46.54 ****
Calculated L/100 = 5.4
Displayed L/100 = 5.0

**** Impossible!!!
Suspect gas pump, Prius tank is 45 Litres capacity (no bladder) and I would have still had 1 to 2 litres left, so it should only have taken about 44 litres max.!
When it hit 45 I expected to get drenched with overflow, thinking that the cutout wasn't working.
Will stay away from that place in future.

Batavier, that first tank looks somewhat suspect: $43/$3.41 = 12.6 gallons! Perhaps you filled a 4 liter container for emergency purposes at the same time?

 

Re: October MPG Averages

Low mileage month for the Prius thanks in part to a leave of absence from work. Only one tank of gas purchased in October.

Tank Miles: 568.4

Avg Tank Mileage: 51.7 calculated, 53.7 via computer.
Avg Overall Mileage: 47.7

Re: October MPG Averages

FIRST TANK! Got my car last Tuesday!

Tank Miles: 402
Overall Miles: 402
Avg Tank Mileage: 46.5
Avg Overall Mileage: 46.5
Avg Temperature: 75
Price per Tank: ????
Avg Price per Gallon: 1.82

 

last tank average mpg 47.. this tank.. 51.. i was speeding on the last tank hehe

miles on last tank 427. This tank 100 miles so far.

 

LOL, indeed. Lemme check my spreadsheet... Perhaps I need to put non-metric values in it as well. I think my calculations were off...

EDIT: Nope, I don't think that's it. What is shown there as average price is the average lifetime price, not the price for that tank. I've changed it a bit, I hope I converted all figures correctly now. :?

 

Re: October MPG Averages

UK models don't have the infernal bladder in the tank, hence the extra capacity?

 

Re: October MPG Averages

Tank Miles: 1150 for the month
Overall Miles: 8613
Avg Tank Mileage: 54.4
Avg Overall Mileage: 52.6
Avg Temperature: 70's
Price per Tank: $17.50
Avg Price per Gallon: $2.28

 

Indeed, European models don't have the bladder, but I 'm not sure if there's more capacity: 45 litre (11.89 US gallon). I managed to get a tad over 46 litre in once, but it was filled to the rim, so there probably were one or two litres in the filling pipe.

I'm not getting better than 38 mpg (U.S.) . Isn't it supposed to be better?

 

Re: October MPG Averages

I just bought an '05 Prius. I get only 38 mpg, What's happening?
