Mazda fuel Consumption Database

It's just an Excel file since I compute for my FC manually [emoji4]

I agree with Mr. J. Your FC is better than mine if we're talking about an average speed of 11 km/h [emoji106]

But that also makes me wonder what your odometer was when you got your unit; and if you reset everything on your multi-info display at the time your unit was turned over to you.

Mine has already ran 26 km when I got in my M3. I reset all the stats on the multi-info display, including the average speed. If I'm not mistaken it was at 9 km/h. The fuel gauge? The last bar was blinking already!

When I got it the odometer already had 7km on it. It was already blinking too. =)

Last trip registered 11.2 km/L.
Mazda2 2018
900km+ on odometer
Makati to Dasma route.

Question: will my fuel mileage still improve? (a few more thousand km?) or it is already at its peak now considering im almost 1000km

It will largely depend on your driving style and traffic conditions. My M3's FC remained consistent between 7-8 km/Li. It's been driven for 3 months with 3000+ km odometer reading.

From 10km/l to 12.5km/l just by changing to a longer but faster route (70km to 80km round trip). Saves me about 0.6 liter per day and 30min travel time


Also just noticed, if i let go of the throttle, the instantaneous km/l skyrockets to 50-60km/l. So minimal fuel is used with no foot on throttle? I guess if I press hard initially and coast I can save more

When coasting long enough, a car will go into DFCO (deceleration fuel cut off), wherein it uses zero fuel and the car is kept running by the momentum generated from the kinetic energy of the turning wheels.

That's why most hypermilers use the pulse and glide technique, where they will accelerate for a certain length of time, and then coast for an equivalent length of time. During the coasting bit, the car uses zero fuel and thus when averaged out, it comes out more efficient than having your foot on the throttle consistently. However, as a caveat, you can only execute pulse and glide with light and predictable traffic as you have to have lots of room to accelerate and coast repeatedly.

This answers my question that I couldn't ask! I've been wondering why the needle will point out to the highest level whenever I let go of the pedal. I might try this pulse and glide thing and see how it works.

at what speed does this occur? rpm needle? tachometer?

Does the VCM happ n at th same time too while the car is into DFCO?

I’ve been trying to do this technique for quite a while too... but somehow I can’t take my foot on the pedal completely. I will just lighten my foot to somehow keep feeding gas to the engine but minimally so as to keep the speed and in effect lesser pulses. Don’t know if I’m doing it right though.

It's the virtual needle for km/L fuel consumption reading.

downhill and no throttle, most new cars will max or nearly max out..

My 2017 M3's recent FC from my northern trip to Baguio.

NLEX/SCTEX/TPLEX 14 km/Li with cruise control set at 100kmh

Uphill battle with trucks along Marcos Highway all the way to Baguio 12 km/Li. The 2.0Li M3 was very easy to drive with just automatic transmission mode when tackling the steep tight curves of Marcos Highway and overtaking the trucks and underpowered sedans. The M3 is smart enough to keep the right high rev (3000-4000rpm) when going uphill. The only time I would use the manual transmission mode was when using engine braking when going downhill.

Body roll was really minimal, quite impressive. Kids enjoyed the ride feel from the centrifugal force whenever I would speed up on an uphill tight corner.

Hmm... 7 km on yours vs. 26 km on mine.

Oh well... we didn't bother asking the sales manager when we got our M3...

This is also what I do, been my practice since my years with my then Altis [emoji4]

With my Altis, the instantaneous fuel consumption goes nuts (99 km/l). With my M3 now, it goes 0 L / 100 km.

There's one thing I've started observing... the "behavior" of the average fuel consumption and of the average speed.

I think I'm arriving at the conclusion that those 2 show varying figures when you reset them after refueling and before starting the engine vs. after refueling and after starting the engine.

The former shows faster km/h, but higher fuel consumption.

The latter shows slower km/h, but lower fuel consumption.

I'm still not sure which of the two methods(?) is correct: resetting after refueling and before starting the engine or resetting after refueling and after starting the engine.

[Altuy]

To illustrate my post above...

The two yellow-highlighted figures are the instances when I reset my average speed and average FC meters after re-fueling and before starting the engine.



Compared to my historical data, the two figures are showing a faster speed, but higher fuel consumption.

I thought something went wrong with my gauges/meters after I brought my M3 to casa for its 6th month-PMS. I even thought the faster speed/higher FC is because they rotated the tires (with just less than 4,000 km worth of wear on them).

I guess I'll have to stick to my "usual" method of resetting my gauges/meters after starting the engine for consistency's sake...

Crazy fuel consumption! At 64.9 km/L, I know this isn't true. This short stretch is mostly downhill.

Hi sir good day, ask ko lang po. ok pa po ba bumili ng Mazda 3 2009 or 2006 tribute at this year 2018.
plan ko kc pag uwi ko dream ko kc magkaron ng sasakyan salamat po
