474km

My on-board computer has finally calculated that I can drive 474km on a full tank of bio-ethanol. This is only 77% of the distance, that I used to manage of a full tank of petrol.

I knew in advance that this was going to be the case, but now I have figures to back it up.

In other words, I need 30% more litres of bio-ethanol than petrol to travel the same distance.

Since bio-ethanol costs 0.899EUR per litre, a 30% increase means an effective price of 1.16EUR per litre, which compared to around 1.42EUR for super (95 octane) at the moment, is still a good bargain.

It’s just a shame, that I have to fill up so often!

A longer motorway trip

Yesterday I had to go to Mainz so I was able to see how the bio-ethanol car performed long-distance on the motorway – to be precise along the A66, which has speed limits on most of it of 120 or 100 km/h.

Anyway, there’s nothing much to report about the car’s performance, except the fuel consumption which, according to the on-board computer, hovered between 8 an 9 litres per 100km.

At the moment I am waiting to see how far I get on one tank of bio-ethanol.  Taking the km driven so far and adding on the expected km that the computer says I have remaining, it’s going to be about 500km in total, which is certainly less than I managed in a similar car using normal petrol.  I’ll know more in a few days…
