Hi everyone,

I'm a french guy living in the mountains of Switzerland.

After having had cheap vehicles (Peugeot 306 HDi mainly) as a student, I have enjoyed myself with a series of "sporty vehicles" including a Citroen Xsara VTS 167, a Mazda RX-8 PZ and a Renault Megane 3 RS.

I have always driven my vehicles with fuel economy in mind, discovering even pulse and glide practise with my RS (allowing some tanks to average 6.5l/100km 39mpg us which is nice I think for a 265bhp vehicle).

But shortly I have seen on Youtube conferences of JM Jancovici, a french engineer specialised and global warming and energy supply questions, which made me feel like I was wasting valuable fuel away.

So I have sold the Megane and just bought a '15 Skoda Octavia 3 Greenline Combi which is I think quite a nice fuel optimised car thanks to aerodynamics tweaks, reasonably sized tyres, a small engine coupled with a very long 6speed gearbox.

So I'm not gonna do huge modifications like some of you, but I hope to discover ways to optimise my driving further, and marginally improve the vehicle without changing too much of it.

As a land surveyor, I will try to share my science of measurements in order to quantify my fuel economy improvements.

Happy to share with you, so far I am on the first tank of diesel and my odb tells me it averages 4.3l/100km (58 mpg us) which is not bad for 0°C, winter tyres, lots of 120km/h or mountain driving.

On the long run, I'd be happy if I could go in average under 4l/100km, without driving too slowly.
