2012 mazda 3 skyactiv - 1000 kms per tank of gas TRUE or FALSE ?

hi there every one,

this is my first post - I am thinking about buying the 2012 mazda 3 skyactiv, I live in Vancouver BC, my work is a hour highway drive away -some of the mazda dealers claim the car gets 1000 km per tank of gas - on my current car chevy optra (same size engine 2.0) I was filling up every 4th day & getting about 480 km per tank - can anyone explain these figures, how many kms are you getting ? , is buying the skyactiv even worth the money here the difference is about $4000 before taxes & fees - nothing definate found on internet yet only you tube, thankyou everyone for time.

I think that 1,000km (about 625mi) is highly dubious. The tank on my hatchback is 14.5 gallons. Nobody is going to let the thing run down to empty. I have been averaging combined fuel economy of 33mpg (53kpg). The sedan is supposed to get 40mpg on the highway and the hatchback 39. If your drive were 100% highway you might get a maximum of just over 900km if you ran the thing down to fumes. With that said, the fuel economy is comparable to many other compact cars on the market, though, the 3 is a bit more fun to drive.

I have an iTouring Skyactiv with a manual transmission and a little over 3K miles. Most of the miles are on highways, but I am a driving enthusiast and tend to hustle the car, heel-toeing and the like, on fun roads.

At any rate, according to the in car computer, I've averaged 35.9 MPG so far. The range for a tank is typically estimated at around 500 miles (805 KM), but it would be pretty close to empty if I tried going that far. I typically fill the car after around 435 miles/700km.

I drive a 2012 Mazda3 iTouring Skyactiv 4-door, manual transmission.

My effective range is just over 500 miles per tank, in real-world driving.

If you got more than ~850km per tank without really cautious driving, I'd be surprised.

It's believable that a Skyactiv Mazda3 could travel 1000km on a tank. If you top the tank completely (and perhaps use higher octane gasoline), and then pull directly from the filling station onto the Interstate, and travel those 1000km on level terrain with the cruise at 100kph, without slowing, accelerating, or turning sharply. And drive until the tank is dead empty.

I would believe that, under ideal conditions, the car can go that far on one full tank of gas. However, none of us drive regularly under ideal conditions. And hopefully none of us are driving until the tank is completely empty.

Is there some specific reason you're concerned about crossing the 1000km/tank barrier? 16 to 17 km/liter seems quite good, particularly from a car that can do a quarter mile in sixteen seconds, 0-60mph in under 8 seconds. For a 155hp engine, the fuel economy is astonishingly high. Would a 10L larger fuel tank make a difference to you?

This entire thread is making me wish the Carter administration had succeeded in getting us firmly on the road to using the metric system in the U.S.

I just got my 3S and filled it up for the first time, 558 miles with almost a gallon left. This is with many stop and go trips, so it could be possible to hit 625 miles per tank. Here is my first fill up details: http://www.fuelly.com/driver/vfrjim/3

I have hit 38.x mpg several times in my 2.3L 5MT, "old" Mazda3. In both of those instances, that was ~550 miles (just under 900km's) with obviously a touch of fuel left over, by careful driving. My car was rated by the EPA at 22/28 mpg. These new models should easily by able to do 1,000kms on a single tank assuming their fuel tank is the same as my first gen car (14.5gal) and that they are efficient as they claim to be.

My experience has proven 1,000km on a tank is possible with a Mazda 3.

I have surpassed that mark twice with my 3i w/o running out of gas.

1,000km = 621.4 miles.
621.4 miles/14 gallons would require averaging 44.39 mpg

Note: The fuel tank in the 2nd-generation Mazda 3 Skyactive 2.0 L is rated to hold 14.5 gal.

On one tank with my 3i I managed to drive 626.0 miles on 13.4 gallons (46.7 mpg), and for another tank I managed 624.2 miles on 13.86 gallons (45.0 mpg)

I've also calculated a partial tank average of 56.1 mpg, based on 204.5 miles driven on 3.644 gallons during a relaxed trip driven in mild temperatures along mostly flat coastal roads with very little wind while limiting my maximum cruising speeds to ~55 mph.

Note that these results were with a 2005 3i 2.0L engine which lacks VVT (variable valve timing) & "Skyactive Technology".

That said, I doubt if many Skyactive owners would be be willing to drive conservatively enough to manage 1,000km on one tank.

But I'm confident that doing so IS possible!

I believe the rumors that it is bad for the car to run it low on fuel as the fuel may cool the fuel pump and the fuel pump may draw any contaminants through that are in the tank. Either or both of those may be false but it doesn't hurt anything to stop to buy gasoline so I fill up somewhere in the 1/3-1/4 of a tank remaining range.

My 3i is only 3 days old with about 70 miles out of the full tank. I have no definitive mileage calculation yet. I got the car hoping to average at least 30mpg overall so that would be 300 miles or so between fills.

Hahaha. I also read that some college engineering students got over 1000 km/tank on some (one person) vehicle they designed. Yes you can get 1000km per tankful. The catch is you gotta drive about 25 mph average. So, I am skeptical of the claim.
