I know there have been several fuel economy threads before, but most of the dicussion in the past has been about average MPG. We all probably have a fair idea of what our average MPG is, but from time to time we might get one exceptional tank which gives us more miles than we have ever experienced before.

I had my best ever tank last week, with 385 miles from the time when the tank was completely full to almost being completely empty. I hit the low-fuel warning around 365/370 and kept on going to 385 before I finally filled up the tank again. Based on what some people have said about the so-called "reserve tank", I speculate that I could have even reached 400 if I had been really brave. But I don't have the ***** to try, so I settled for 385 miles as my best single tank ever.

Not sure if this is a nice record or not, but it was pretty amazing to me. I usually get 340 to 360 on a tank. My 385 was achieved using Shell gas with an Injen intake and almost entirely freeway driving at a consistently high speed (no traffic).

 

thats pretty good. i average around 335 or so but my best was almost 390

 

Nice. Any idea what contributed to your 390-mile tank? Was it all freeway driving?

 

i managed 400 miles outta a tank during my road trip to IN. all highway, cruising at 70 mph, replaced the filter with a K&N drop in and removed the snorkel.

 

Very nice. Did you really push it to the absolute limit, or did you have some miles to spare? I feel like I could have pushed it to 400. I just don't want to be the idiot left pushing his car on the emergency shoulder to get to the nearest gas station.

 

i think when i filled up it took like 12.XX gallons, the empty light came on probly 370 miles, so i might have gotten another 20-30 miles till dead empty.

 

wtf, my best was 275

 

I've hit close to 415 once I think - almost all freeway. More typically, I get around 330 to 360 or so before filling. These days I usually do half freeway half city and get away with aout 26 mpg. I also tend to drive for another 20 or so miles after the light comes on, so that might have something to do with it. I've noticed that when I fill it right when the light comes on, it's only about 13 gallons, so there should be another 1.5 gallons to go right? and conservatively, at 20 MPG, that would get you another 30 miles...

 

 

I don't know exactly, but thats about what i get too lol

 

Thought it might be pertinent to add that I'm automatic (I've seen it stated in a lot of advertising and catalog materials and reviews that the tC is slightly more fuel efficient than the manual).

As for driving habits, in city driving I'm pretty mild. Sometimes I'll quickly accelerate to 45 but most of the time I'm careful and slow (attribute that to "new car syndrome" and generally trying to keep other people away from me lol).

On the highway, I like to average about 85 mph but I have found that I get the most efficiency right around 75. I drive about 400 miles round trip on the freeway each weekend, so I like to gun it to about 95-100 to keep things interesting and keep me from falling asleep.

What gas do you guys like to use? I've used Mobil, Citgo (or whatever it is now), and Chevron. Primarily I use Chevron... but I haven't had the car long enough to really have a good enough dataset to compare whether or not one gas is better than another in this aspect...

 

I got to 340 and figured I better stop and get gas as I was in the mountains and about 340 miles from home and only a mile from the station..........but I think I could of gone more..........It was from Tacoma Wa. to Medford Oregon........but the last 35 miles is nothing but mountains up and down..........

 

out of 8 tanks of gas i bought since i have purchased my car the best was 330 miles... but do take into consideration i bought the car in October so ive only had it while its been really cold out..right now ive been averaging 24-25mpg which isnt to bad. im positive ill beat the 330miles this summer no problems

 

i ran my car to 381 the other day going to two gas stations which had no gas (working on pumps) and i was in the last black line on the gas gauge... almost ____ myself lol... and with the true spirit of the tc i didnt even take it easy while looking for another gas station LMAO!

But thats my best one day im going to use a whole tank no hot roding just cruising at the speed limit every time... see what happens

 

I think 345, because I was at pre-pay gas station and I put $37.00 when I should of only put in $35.00.

Here's my typical mileages on each line.

Quarter of full tank- 110-85 (mainly get those when using remote starter & long idling.)

Half tank- 210-215

Quarter tank- 310-320

Never been crazy to pass the "R" line been close due to no money to refill and it was payday. I think that was 375-380 range.

Average, is 310-320 @ quarter of a tank; depending on how much more highway than city. Including heavy footing.

 

Ive only ever gotten 320. Now Turbo I avg 300 a tank.

 

Maybe 300ish... Have only filled up twice now. 85-90% city driving so that eats up a lot. I think it will probably improve as time passes.

 

X2 i dont even drive it hard.

 

City driving I get like 225 miles I gas up at the 1/4 mark.

Freeway get like 270 at the 1/4 mark.

 

My best trip almost hit 425 miles. I average around 350 miles per fill up.
