2009 Mazda 6 GT: Can do easy

I want an easy 350 miles before I fill up, knowing I have a couple gallons left. My G35 averages 21 mpg.

Average 550 in my 2006 Jetta TDI. Won't impress the chicks with the horsepower though.

I'm terribly annoyed by anything less than 700km (around 430 miles) or expected range, but that's just me used to euro diesels.

My wife's 2009 Accord will blow past 400 miles with mixed use - I think we hit over 500 on one tank (all highway) on our trip from Dallas to Phoenix. My 2009 Civic Si requires more regular fillups as it gets to about 330 miles before the light comes on with 80% highway/20% city driving. While I wish it had slightly better range, it isn't that bad to me.

500 from my Prius
250 from my Tribeca

400 from my Mazda3.
400 from my Yukon around town, easily 500 on a highway trip. Would love to try for 600, theoretically quite possible with a 31 gallon tank. But the wife gets antsy, and I usually decide to look for a good price and stop anyway when I get down to a quarter tank. My all-time high was about 550 miles. The light had been on for 50 miles, so even I got a little anxious and caved in. Durn thing only needed 28 gallons.

Nice course, so many trees for the desert... there's an environmentalist's dilemma... appreciate the trees, or get angry about how much water they need?

400....or so is fine....the 250 referenced above is way out of line for a vehicle of that type, IYAM.

I think this depends on how/where you drive. If I have a week where I am driving only in rush-hour on San Jose's congested roads sometimes I can't even get 300 miles out of my 24 gal tank. On long highway drives I have gone 600 miles before needing to fill-up and I usually average between 350-450 miles. If you live in a big metropolis your idea of fuel range is going to be vastly different than those who live in small cities.

400+ on the highway on my Mazda3 2.3L if the a/c is off and I go easy on the speeding.

220 in my Miata. I'm glad I take mass transit to work.

16.9 gallon tank and gas mileage of 14MPG or less and that's optimistic, but pure highway driving yields up to 415 miles.

'04 Mazda6i, 390-400 in winter (New England), prob 410 in summer, mixed driving. When the light comes on, I consistently have 3 gallons left; that means about 80 miles of gentle driving left, more than enough distance to find a cheap gas station. I used to drive between memphis and st. louis a lot, which is just about 300 miles, so for many years i was fine with 300+ range with a couple of gallons remaining. now i expect 400 minimum (the G37x does that in mixed driving; the '04 Forrester barely gets 270, which annoys me very much).

when people say "quarter tank," do they usually mean "total tank volume divided by 4, regardless of what that stupid needle reads," or is it "when the notoriously inaccurate needle hits a certain mark that is about 3/4 way down?"

My SRT8 Jeep gets about 230 in the city and just breaks 300 on the highway with about a 20 gal tank. I recently bought an FJ Cruiser and the tank is tiny and with the 3 inch lift and 33" tires only about 210 city, not sure on hwy as I have not taken it anywhere yet. My wife gets 330 miles pretty much all the time in the city in her '01 BMW 330Ci.

Some of you forgot to mention the size of your fuel tank. e.g. it would be easy to "blow by" 400 miles if your fuel tank was 20 gallons and you averaged 20mpg.

2009 FX35 AWD

The best I have done is 550 miles all highway before filling up. I just set the adaptive cruise at 70 and let it go. That trip I averaged 25 MPG and could have gone another 50 miles.

I average 21 mpg on my 40 mile daily commute which is about 33 highway miles. I fill up at 420 miles and usually have over 4 gallons left in the tank. Its pretty easy to hit 500 miles without filling.

MDX '07 I got close to 450 miles (well it has a big tank). 400 miles range is not that uncommon especially if tank is little bit larger.

about 420 on the highway with a 14.5 gal tank in my GTI... perfectly acceptable to me.
closer to 320 in city/fun driving.

I'm very happy if I get 400 miles highway out of our 02 Tahoe (24 or 26 gallon tank, not sure as it didn't come with a owner's manual). We average about 19 mpg at 75 mph so that leaves us a small reserve. Around town, 275 is a great result.

My S2000 used to return 300+ mile tanks on long highway trips, but was lucky to break 220 miles in town (12 gallon fillups on a sub 13.2 gallon tank). Now that I run it on ethanol I'm estatic to get 160-170 miles to a fillup in mixed driving. I think I could break 200 miles highway only, but what's the point since ethanol is hard to find on the west coast.

My EvoX is capable of hitting 325+ miles highway (13+ gallon fillup), but around town 200-225 is more like it.

When it comes to range they all make me miss my departed G35 Coupe. LA to Phoenix (400+ miles) was a cakewalk and left me plenty of gas (nearly a 1/4 tank) to toodle around town with for a couple of days. My best tank ever was on the way from LA to Bonneville. Despite the climb in elevation, I was still able to go nearly 450 miles before the fuel light came on (over 27 mpg). Definite 500+ range in that car if you keep the speed down.

If my Outback goes 300 miles on a tank, it's because it ran out of gas at 270 miles and I pushed it for another 30.

91 GMC Sierra 1500 4.3 L V6, 5 speed, 3.08 gears, 34 gallons, 24 MPG, 800 miles - I should never have sold it.
96 GMC Sierra 1500 5.0L V8, 5-speed, 3.42 gears, 34 gallons, 21 MPG, 700 miles...but it sure goes up hills and into the wind better.
89 Volvo 240 DL, 2.3L, 5-speed, 16 gallons, 30 MPG, 400 miles (450 would be possible except is has the world's scariest gas guage - points below empty with 4 gallons left).
93 Buick LeSabre, 3.8L 4-speed auto, 18 gallons, 29 MPG, 500 miles
04 Suburban 2WD, 5.3L Flex-Fuel, 31 gallons, 19 MPG on gas, 550 miles on gas. 14 MPG on E85, 400 miles on E85.

I usually fill up with about an 1/8th of a tank left...that usually means somewhere in the 10 to 11 gallon range for my 14.7 gallon tank in my GTI...at 27 to 30 MPG typical, that means I expect at least something in the high 200s from my car and usually end up with somewhere in the neighborhood of 300 to 340.

Used to have a 95 Accord. 2900 lb car, skinny tires, gutless little 4 cylinder, 17 gallon tank. Could break 300 city, 450 highway with a couple gallons to spare.

Around that time uncle had a 95 Camry. 3000 lb car, also a gutless 4 cylinder, 18.5 gallon tank, 500 miles highway no problem.

Don't understand why 15 years and 500 lbs later the gas tanks have barely budged such that 400 miles without getting down to fumes is now an achievement.

Nissan got it right with 20 gallons in the Altima but they're about the only one.

I like colorado kid's format so I will "borrow" it.

99 Ford F150 5.4L V8 3.55 gears 30 gallons 15 MPG with mods 550-600 on all highway 250-300 in city. Its not a hybrid that's for sure.

550ish in my Mini Cooper if I spend at least half of the miles on the highway.

Somehow, i've never gotten over 300 in a tank for my 06 g35x. I never do much highway driving but also never have had to put in more that 15 gallons. Usually average around 18 in mostly city and suburban driving, which i think is pretty good for a high strung engine like the vq35

My 8 year old bmw 330ci can get 35 mpg, and it has now near 250hp. So, that mazda does not get a very impressive mpg for a 2.5l 170hp

The family 2001 Volvo S80 T6 (twin-turbo) 2.8L has seen over 550 miles on mostly-highway stretches. Fun and peppy car to drive, not to mention comfortable to cruise in. And pretty good for a 21-gallon tank (80 liters). Averages about 20 mpg in mixed driving.

The family 2004 Toyota Sienna could do better...3.3L V-6, 20-gal tank, about 17.2 mpg overall, according to the trip computer. Annual trips to Florida usually see 24 mpg on average, so over the 400-mile mark there. Wish it had a larger tank for more cruising between fill-ups.

My 1987 325iC has been averaging 23.7 mpg in mixed "spirited" driving. As in I'm a leadfoot. Gotta love that inline six. But I'm pretty conscious about shifting, and the 14.5-gallon tank can take me a smidge over 300 miles before I fill up (I usually let it run into the red).

I usually get 350 or so out of my HHR SS in mixed driving, can top 400 on all highway. With a 16.2 gallon tank this puts me at an average of about 24-25 mpg mixed, topping out at 27 or so hwy. Probably could get better but I do have a bit of a lead foot.

Just got back to OC from southern Utah. 510 miles, filled up when we left. Got home and the range computer in our VW CC 2.0T said we still had 80 miles left until empty. 18 gal. tank running at 80-85 mph average. Computer said 32 mpg for the trip.

300 miles per tank is my minimum. Anything less is not acceptable. More than 400 miles per tank is good but not absolutely necessary. 400 miles is 5+ hours of highway driving; by then I'm ready for a break anyway.
