I am just running in my new Mazda CX-30. It’s a 186 horsepower petrol engine. 2 litre AWD automatic. I am shocked at how much fuel it consumes. Over the first 400 kms it’s drinking 10 litre/100 kms in town - short trips. That’s only 23 mpg. Mazda advertising this spec vehicle at 5.8 litre/100 kms. That’s 40.5 mpg. Am I doing something wrong? I’m driving it very gently - no fast acceleration etc…?

don't be overly concerned about your fuel economy till you get a few thousand km on it. You are getting use to a new vehicle and it also starts learning how you drive.
Any advertised fuel specs are for comparing against any other similar vehicle as they are all tested under the same conditions therefore "Your fuel economy will vary". Not sure what your 5.8 figures is, is that city, highway, combined?

In town driving and short trips (stop and go, etc) are what consumes the most amount of fuel. Try it on a more long distance trip outside the city and see what sort of figures you come up with.

I have the 2.5L 186hp engine and get 26-27mpg with 95% short (less than 5 miles) trips. When you drive some distance it goes up significantly. I don't think you can really consider it much until you get over 1000 miles on the car.

Hi, actually i would agree with the other comments about not to worry to much for few KMs. Although our car specifications are very different than in the USA or Europe, im on 4775km now and yes it consumes like crazy. We dont have turbo but we have sport mode. it really makes the car more fast and... aggressive. even not using it it still consumes so much fuel. Well, here we have 2 different opinions.. some says its normal for few first KMs but i say it still drinks fuel for me. im using 95 btw (can use E85, E20, 95)

AWD 2.5 Skyactive G without Cylinder Deactivation. Mixed driving and have averaged 31MPG over 33,000 miles.
I drive about 60/40 city/hwy and for an avg am getting 27 as epa says. I have gotten anywhere from 32 to 36 strictly hwy(mountainous terrain) and as low as 23 city only with lots of stops and short trips.

Mine is the UK 2.0 petrol Skyactive X 180 and I have done 413 miles on a full tank with 60 miles to go. The trip is showing just under 50mpg.

Mine is pretty much the same. I am getting just under 500 miles on a tank predominantly driving in the city and with iSTOP switched off. My car is eSKYACTIV MHEV 186 PS, FWD Manual box.

I do a mix of city and highway driving. Been averaging 7.9L per 100k.

The spec for my Skyactive-G 2.5 litre 186 hp is 9.9 litres/100km in the city, and that is spot on.
On the highway, the transmission really helps this car. I get much better than the advertised 7.9 litres/100km.
But again, mine is the Skyactive-G... not the Skyactive-X.

Have 2021 Slect 2.5 L engine, AWD, have put 6000 miles since September 2020 and overall average is about 28.5 MPG (US Gallon) with a range of 25.9-29.5, mostly 'suburban' driving with a mix of urban and highway driving.

My CX-30 2.5L AWD has 1500km on it now and driving the same route and same sedate style I did with the 110 TSI VW Tiguan I had before, the CX-30 is using 7.8 l/100km compared to 6.3l/100km for the Tiguan. However the Tiguan did use 95RON fuel whereas I'm using 91RON in the Mazda. At 100km/hr and above the gap narrows.

It's at low speed, low throttle operation where the downsized turbo engines used by VW really start saving fuel.

2021 Skyactiv-G 2.0 AT fuel consumption: 6.7 l/100 km. Summer/ winter 50/50. Measuring distance 5000 km. Fuel 98 octane, 5% ethanol
Have you noticed any difference between 95 and 98? The dealer said there wouldn't be anything noticeable. I used 98 on my previous car because the manual recommended to do so, but I have no idea if it made any difference.

I have the Skyactiv-X AWD AT but I'm still at something like 150km and 80% left of my first full tank, so don't know any real stats yet, but the values it has been displaying have been slightly worrying, I think I'm above 10l/100km for now, but that's almost exclusively city driving and some "let's see how fast it accelerates" type of fooling around.

Finnish tech magazine Tekniikan Maailma has compared 98E (5% ethanol) and 95E fuels (10% ethanol) related to fuel economy.


The result was that fuel consumption increases 3 % when using 95E instead of 98E.
