99,990 mpg....
catgut Sat Jan 22, 2011 3:23 am
I read this thread on 3gwrx.com http://www.3gwrx.com/forum/index.php/topic,11032.0.html
Quite funny how people interpret MPG. Don't forget people, instantaneous MPG is not indicative of MPG per tank
I've run the whole gamut of MPG in my cars. I've achieved as high as 62 MPG (tank avg) in my wife's Prius and 31.8 in my '08 WRX on a Stage-2 tune here on our stop & go, rain at will, and at the mercy of "bad-driver-island".
Now I'm achieving about 24~26 MPG with 'normal' spirited driving (stop light pulls, 2nd gear kills
, etc.) but in the end as someone in the thread summed it up, if I wanted to get good fuel economy then I shouldn't have purchased a WRX. Drive the car for what it is and enjoy your Subi

62mpg on the Prius..whats the fuel capacity for the tank on the Prius?? Our Civic hybrid is tops 10gallon tank capacity @ 43mpg..just wondering??

sinR,
Sounds similar. If you didn't know the Prius fuel tank capacity is variable
It's a bladder that expands or contracts based upon ambient temperature to help control vapor emissions further (less air above the fuel = less fuel vapor). If temp is above roughly 70F then it's capacity is at max (11.9 gal) so we get the full benefit being on Guam
Colder states/areas will only get about 9 gal or so, roughly speaking.
We can never bring this tank to below 2-bars so when we refuel we're only putting in approximately 5.5~6 gal and spending about $20 to 'fill up' the tank.
I have to comment though. I stated 62-MPG as my 'highest' achieved but that was with A/C 'on', OEM wheels/tires, and new. We put on the Scion tC wheels about a month later and dropped the fuel economy down to 57-MPG...the effects of heavy wheels make a difference
All in all without trying we are now averaging 43~47 MPG driving 'normally' and still out accelerate most cars from a dig. people still don't get it when I pull on them until 50 MPH and they wonder what the hell is under the hood
YES, Prius is slow (it's not a high speed king by any means) BUT, for those of you who know anything about electricity; electric motors produce their maximum torque at roughly 1 RPM. Nothing but brushless permanent magnet high-tech motors and a 270-VDC NiMH battery pulling this little 47 MPG baby from a dig and torque is abundant. Beware
don't get caught in a stop light battle with a Prius with your friends watching

Note: when i say 10gal, its normally how much we put in inorder to calculate mpg.sinR wrote:62mpg on the Prius..whats the fuel capacity for the tank on the Prius?? Our Civic hybrid is tops 10gallon tank capacity @ 43mpg..just wondering??

Makes sense since Honda's site shows the 2011 Civic Hybrid having a tank capacity of 12.3 gal; 10 gal nice round number to calculate mpg. Regardless of what you aim to put into your tank you can still divide the quantity input but the distance-to-empty traveled and over time it will reflect your tank mpg. What does your in-car mpg display read?
Ours is spot-on and we double check it against our fill-ups since I've kept a log of all service/refuels since purchased.

We always zero it out..but would get 420-440(average 430). I dont want to change out the rims cause then it would drop drastically into the high 30 mpg. I think the Prius is built better economically. And yes your right bout the take off with the battery assist its feels like a 10% subaru launch...i think 10% is too generous maybe 5% subaru lauch feel when you blast it on the green at the streetlight LOL

note:420-440 is the digital odometer reading i would just divide by 10 gal which gives miles per gallonsinR wrote:We always zero it out..but would get 420-440(average 430).

I get about 13mpg in the sti and about 19 in the mustang with just normal driving. But with the sti on the highway with the cruise set around 75-80 it gets about 24mpg

Yup, decent numbers considering Guam
We're achieving about 280 miles per tank, just remember that we're only consuming about 6 gal from full to empty so that works out to 46 mpg. I'm so used to gauging a tank of fuel to equal about 400~500 miles and was alarmed with 280 until I recalled that I only put 6 gals
Stop and Go traffic is usually a good situation for a series/parallel hybrid (Prius) and it definitely shows. I'm no hyper-miler but I do appreciate a good reliable car that doesn't run me into the ground with fuel and maintenance costs. And it's nicely equipped. I'm sure the Honda is similar just not a series/parallel type. To each his own poison.
I'm a car guy so brand loyalty doesn't really exist in my mind. I definitely cross the party lines when it comes to vehicles

Lol, this will be my Subi mpg will be in a couple years when warranty expires
You're fortunate to buy fuel on base at the very least.The way I see it it's all about averages....
Prius = 46 mpg
Subi = 31.8 mpg
Total household average = 38.9 mpg
Not to shabby for Guam I guess
