2015 Mazda 6, Skyactiv 2.5, 6 Speed Auto. 306,000KM. Tuned on 91 Octane.
The best fuel economy I have ever seen was about 4.4L/100km (53mpg) during steady state cruising at around 60km/h.
When driving in warmer weather on summer blend fuel, I will easily average 5L/100km during steady state cruising at 80km/h or less.
Driving style: Mostly one or two lane highways, little stopping, mostly conservative throttle inputs:
Summer avg. : 5-6L/100KM (47-39mpg)
Winter avg. : 6-7L/100km (39-33mpg)
Stop and go driving: 6.5-7.2L/100km (36-32mpg)
This is all with ethanol-free 91 octane.
The use of ethanol-blended 87 octane in the past reduced these figures by an avg. of 10%.
