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..
