Guys, I received some interesting info yesterday from a customer of mine who works at a refinery in the UK.
This is about unleaded fuel. From the beginning of December, European legislation has changed to say that all unleaded fuel must have 5% Ethenol mixed in. I have read about this ages ago. However, this is causing issues.
Sainsbury are already using this and the filters in the storage systems are blocking at an alarming rate.
If I have got this right, Ethenol is in effect plant based there is alot of water content in the make up of the fuel. The problem that has been occuring is that when mixed, it can absorb the moisture in the air of the tank and after a period of time the fuel starts to separate in the fuel tanks on the forecourts. This of course is not good if pumped into your petrol tank.
It is expected that this will cause running issues of petrol cars and irratic running and a little loss of power is expected. From what I was told, it could take until next spring to sort the problem out. The Americans had this issue but have got past it.
So be very careful. There is one solution though, apparently you can't mix super unleaded with ethanol as the octane rating it effected. So to get by until it's all sorted his advice is to run on super.
Morrisons - Avoid Morrisons diesel, they are still buying summer diesel instead of winter diesel now. Summer is cheaper to buy whole sale but as it does not have the ingredient to stop waxing in winter months. Their fuel is the lowest grade of diesel you are allowed to use in the UK, it conforms to BS but right at the bottom end.
Hope this helps
