When bio-ethanol gets cold
With the temperature dipping to -2°C this week, I had an unexpected chance to find out how bio-ethanol reacts to the colder weather.
This is not as cold is it can get in winter here – I’ve experienced -18°C before now! But with the cold wind blowing it certainly felt different to the temperatures that we had been having the previous week.
When bio-ethanol gets cold it apparently gets sluggish. This is why there is a socket on the front of the car, so that I can attach it to the mains and warm the tank up slightly before driving off. Well, that’s the theory at least. As I don’t have an electrical socket anywhere near where I had parked the car, that wasn’t really a solution.
The alternative is to put some normal petrol into the tank during the winter. Again, the drop in temperature came so unexpected, that I hadn’t done this and had only E85 in the tank.
So I drove off anyway – and I can’t say that I noticed any difference. Perhaps the cold temperature hadn’t affected the bio-ethanol as much as I had expected? Perhaps it just wasn’t cold enough yet!
I shall be keeping a watchful eye on the thermometer and may well start mixing in some normal fuel next month.
