Mazda5 real-world Mileage numbers

Have been looking at getting a 5 for the wife and love all these numbers.....except the gas prices for all the U.S. posters. Converting our litres to U.S. gallons and the fact that the $ is at almost par, I'm paying the equivalent of $3.80/gal and i know it's higher in other parts of Canada.
 
checked more carefully this afternoon. 3500rpm @ 75mph. about 3750rpm @ 80mph. 5th gear of course.


Made 2 trips recently. Confirmed the above. Basically, 5 mph = 2500 rpms, roughly; 5 speed manual. So now I have a reason to not exceed 80 mph. (angel)
 
Went through my first tank on my newly purchased '06 autotragic this weekend. Most of it was highway with a maybe 10% bumper to bumper and city driving. Averaged 28mpg.

Hi Marvin,

First thing I must say is that I found out (you probably already knew this) that the MPG here in Canada is like the one found in the UK, not in the USA. Let me compare something with you... 2 vehicles - different categories - different engines - different size.

I used to own a Hyundai Accent 2007 stick shift - basic model - no options.
Now I own a Mazda5 2009 stick shift - basic model - no options.

I live in Montreal - 75% of my driving is in town, 25% highway (105Km/h).


Let's talk gas numbers :

I drive about 18 000 Km per year.

- Winter average with the Hyundai : 9.5L/100Km (24.7 US Mpg - 29.6 UK Mpg)
- Winter average with the Mazda : 10.0L/100Km (23.8 US Mpg - 28.6 UK Mpg)

Best tank (3 years of ownership) in the Hyundai : 8.5L/100Km (27.6 US Mpg - 33.1 UK Mpg)
Best tank (so far) in the Mazda : 7.9L/100Km (29.7 US Mpg - 35.7 UK Mpg)

At the end of the month with gas prices in Montreal (average of 1.11$/L), so far it costs me about 10 bucks more per month than with the Accent.

As for bang for the buck - what a world of difference for 10 buck a month !!


How much does gas go for in your area?
 
First whole tank on my normal driving, which is about 80% interstate @ 75mph and 20% city driving. I got 26.1mpg out of that tank. '07 with 80k+ on the clock. I'm estatic coming from a Tahoe getting 15.5mpg (headbang)
 
Each time I try to determine mileage with this car I become less confident in the numbers. This thing either doesn't fill all the way up or comes spewing out all over the side of the car. It's never the same thing twice. I'm convinced a scan gauge is the only way to even approximate usage accurately. People say that get good numbers by looking at gallons added versus mileage. I don't believe it. I've been doing this for too long and gotten way too whacky of numbers from this car to believe experiment-based numbers any more. It really drives me nuts. I have to say though, I hate having to go wash my car because the gas tank is poorly designed more than I hate not being able to determine the gas mileage. The worst is when my fiancee drives around for days before telling me that it poured out all over the side of the car. And of course she's too lazy to just clean it herself.

Go ahead and fill up your tank today till the nozzle shuts off, then add a little more if you want. Write down your mileage and date on a piece of paper, keep that in your glovebox.

Everytime you add gas for the next few months write down the number of gallons including the numbers past the decimal point, the car's mileage, and the date. You'll have accurate numbers. The amount of gas that spills over the side or "could be added" is minimal when you are talking about many tankfuls.

By the way, I went through a tankful last weekend, mostly interstate at 70mph to 75mph - only got between 25 and 26 mpg. Not bad, but not good. 5-speed manual. For comparison, in my '99 Honda Accord I get 28 to 29 mpg regularly in mixed city/highway driving (also a 5-speed manual).
 
my wife doesn't always reset the odo when she fills up, but when I'm doing it, we are always around 25mpg. that's mixed, hwy and local. it's our only car, I'm hwy carpooling 2 or 3 days/wk.

No, I won't have accurate numbers. I know how to check MPG (using the odometer) and have a degree in math and in engineering. I check the mileage on every vehicle I own and have for over 20 years now. This car is different than all others.

I checked the mileage for the first 15,000 miles and never got a reasonable response. I'd get 32 in the city and 22 on the highway. It has to do with the shape of the tank and the neck. The slightest angle change causes the messed up neck shape to not fill the tank completely. Also, I'm not saying that the spilling affects the numbers. I'm saying the spilling is proof that the neck/tank design is crap, confirmed by all of the gas cap, tank, and neck replacements on these cars. "Real world" numbers on these cars are bogus numbers. I'm not the only person who feels that way because every owner i've ever talked to in person confirmed the same. I just say it gets about 25 MPG and call it done now.

huh. haven't had an issue yet. we almost always go to the same station, never had a spill, and always takes the amount I expect it to. I just know that if I'm between 275-300 miles, it's going to take around 12 gallons, every time.
we did a big road trip soon after we got it, however, and there was one fillup where it didn't take as much, and when I did the math, it showed 19mpg, on a trip that had a best of 29, and all others were in the mid to high 20's.
 
'09 sport manual

Mine's an '09 too. Oh well, I quit trying to explain what is wrong with this car a long time ago. As I was saying, these cars have bigger issues than gas tanks that spew gas all over the side of the car, which is kinda sad really.
 
First tank through the brand new 2010 Sport 5sp came out to be 22.898mpg. A little less than I was hoping for but not bad when I wasnt used to the clutch and now Im realizing this gearbox is geared pretty low through all the gears meaning I was shifting way later than I should have been and running the RPMs too high for a best mileage situation. I calmed down the RPMs for the second tank and am hoping to see more like 28mpg...

You're not going to see 28 unless you're out on the highway the whole time, or if you're hypermiling, which is extremely boring.

Saving money isnt boring... I dont need to be ripping through every turn or be trying to beat every person next to me at a red light. I bought a micro-van. If I didnt care about mileage and saving money and flatout performance mattered to me I would've bought a Speed3 for a few more dollars...
 
Just got back from first test of hwy mpg going from the greater St Louis area to Santa Claus, IN (Holiday World ROCKS!) and back. the car was loaded with my wife and I and our two daughters, the back was full enough to make the back window unusable, A/C on auto, cruise set between 70 and 75, the car got 29.4mpg. This was on a green engine (turned 1000 miles on the way home). I'm very pleased.

Hypermiling the 5 is very laborious because of the fact that the engine works so hard at lower speeds to get the speed up that you are not actually saving gas, but wasting it. I've tried it and I only got in everyone's way.

I baby our 5 big time and don't believe that going slower will do anything other than hurt mileage because the little 4 banger is in a lower gear. If you flip it over to the fake manual shift you can make it go into higher gears, but in my opinion it is a waste of time and energy because it saves a negligible amount of gas, if any (which I doubt). I do not, by the way, ever rip through turns or try to beat anyone to a redlight. I'm am usually the slowest of all of the cars around me. I do however try to get the car in a higher gear so that inertia assists the engine.

My opinion is that driving slow in lower gears hurts the gas mileage, especially in the 5 due to engine size and weight.

2006 4-speed automatic, purchased Dec 06 in California (and remember we have tougher emission standards here).

Exactly 3-1/2 years later my totals are:

17833 miles (yup, only that many; I try not to use much gasoline....)
682.119 gals
= 26.14 mpg

I always fill the tank till the nozzle shuts off, and I don't "top off."
 
Just rented a 5 for 3 days.

2009 Sport Auto+fake shift with 33K.

Drove it kind of hard in a mix of suburban roads and highway.
Total 55.3 miles and filled up was 3.32 gallons = 16.6 MPG!! (nailbyt)
