Today I had an appointment about 100km today, and it was only last night that I realised that I didn’t have enough bio-ethanol in the tank for the return journey.

For the first time, I had to make a detour to fill up with bio-ethanol, meaning that I had to leave earlier to allow enough time to drive to Bad Homburg before I hit the motorway.

Of course, I could have driving down the road to the nearest petrol station and filled up with normal 95-octane fuel, but with that sort of fuel costing around 50% more than bio-ethanol, I felt it was worth making the detour.

But the whole situation did make me conscious of the restrictions of the bio-ethanol fuel.  After all, I don’t get as many kilometres out of a tank as I used to with normal petrol.  I quick check of the list of petrol stations that stock E85 also showed me that there was nothing suitable in the area that I was travelling to.  Well, at least not without going out of my way and looking for it.

So in the end I took the quickest option and visited my usual petrol station, and wished it hadn’t been necessary.  Will the main petrol stations, especially those on motorway service stations, ever start stocking bio-ethanol?

I’m sure that many readers will remember the days when petrol stations had attendants that put the petrol into the tank for you - before the days when “self service” became the modern way of filling up.

Well, perhaps we are going to return to that kind of service. I’ve been fascinated today by a video of a petrol station in the Netherlands, that uses a robot arm to fill up the cars.

The robot knows from the type of car how to open the petrol cap, and presumably whether or not to put diesel in. I wonder how it copes with bio-ethanol?

It looked rather slow at the moment, so I guess the queues at the petrol station near here would just get longer. I also didn’t see anywhere to pay for the petrol - does the robot arm swipe your credit card as well?

As fascinating as it is, I’m still not too sure what to make of it all. It may be nice not to have to get out of your car, but it doesn’t help the unemployment figures!

Today I filled up with bio-ethanol for the first time. Germany’s first bio-ethanol petrol station is located in Bad Homburg and to operate the pump I have a coded key, which allows me to go there at any time of the day, regardless of the opening hours.

For my first visit, however, I decided to go there whilst it was open, just to make sure that there were no problems.

Actually there was a problem - a car had parked on the space in front of the bio-ethanol pump, and I had to wait about 15 minutes until it was moved.

After that I parked there myself, turned the key and filled up the car. As simple as that! Now I have a full tank and can work out for myself how much the car is using. The on-board computer says that I used 13.3litres/100km since I started driving the car, but I don’t know how many litres were in the tank when I got it so I can’t check that figure.
