Regular. Premium offers absolutely no advantages amd may, in fact, be detrimental.

try to find one without ethanol if you can, it hurts mpg

I use only E10. I'd rather use a renewable fuel as much as I can. I think using carbon which has been captured from the atmosphere means I am contributing slightly less carbon to the environment. I think this is more important than the number on my display.
I haven't noticed an increase in fuel consumption on E10, maybe if I switch to standard petrol I might.

E10 is 3c per litre cheaper than straight petrol which is due to lower duty on it.

I always use E10 - because I support renewable fuels - and I still get 55 MPG in my Prius. If that's a sacrifice, I'll take it.

regular. E10 if I head down to the States.

why does E10 lower the MPG?

Regular. 87 octane. I think, but I'm not sure, that it's always E10. I think E10 may be the only kind of regular I can get around here (NY)?

Ethanol has a lower energy density than petrol
Energy density of Ethanol = 24 MJ/litre
Energy density of petrol = 34.6MJ/litre
Energy density of E10 = 28.06MJ/litre
From http://en.wikipedia.org/wiki/Energy_density
I have my doubts about these figures as they indicate ethanol has negative energy when added to petrol??

This may be more acurate

Ethanol = 84,600BTU/Gallon
Petrol = 125,000BTU/Gallon
E10 = 120,900BTU/Gallon
Less than 4% less energy in E10 than in petrol
From http://en.wikipedia.org/wiki/Gasoline

The cheapest 87 octane I can find- 64K miles and runs perfect w/o any troubles.
