There's a choice of two at the pumps these days, E5 or E10 based on the percentage of ethanol. I only use E5 in the Jeep and the pump price was £1.62 per litre. I also add a drop of lead substitute and if I've had to use E10 a drop of ethanol protector additive too. I also filled a Jerry can of E10 for the mowers and other tools, price of that was £1.50 per litre.
My truck is diesel and last fill up a few days ago it was £1.59 per litre. Those prices can be beaten locally but that place is closer and always has E5.
