You use the phrases 'regular petrol' and 'gas consumption' in the same sentence and yet you are neither in Europe nor the United States.
Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome, some useful advice about posting to the forum and convince me your aren't a spammer.

Ummmm, no.
.
I've been using E10 for over 20 days without a single issue. In that time, I've accumulated sufficient data that proves the real-world loss of mileage is ~3% which matches the calculated loss quite accurately.
This is slightly more credible than mowing the lawn once.

Let's see some of that credible data, Black and white or whatever crayon color you used to document with...I bet it is on only one vehicle type and not a real broad spectrum compiling...
3%??, come on, what bodily orifice did you pull that number out of?..Do you even have 100% gas to buy so you can do a real world comparison test?
i.e.,..My Landrover went from 17 MPG on E10 to 19 MPG average on 100%...My H3 Hummer went from 15 MPG on E10 to 17.5 MPG on 100%...you can do the math, right?
I guess I have to be literal for you people

Obviously your mother didn't.

I assume you really do believe what you report. So, I guess you are one of those guys who does not believe in science and engineering principles. You run an experiment, you find your facts and that is it.
Sorry, but some of the rest of us with education have just been brainwashed to believe that 500 years of scientific method and the understanding of basic thermodynamic formulas predict results. You probably wont be able to convince us that we have been hoodwinked. I assume it is all a big conspiracy by the government and big oil.

I had some experience of running the XJR on various fuels in the UK, Continental Europe and Australia.
97 & 99 RON in the UK
100 RON in Germany & Switzerland
98 RON in Australia
Same car, different fuels, very different highway economy.
I got the best highway economy on the 100 RON, even though it was with higher speeds on the open road.

From 8L/100km to 12L/100km depending on... circumstances.

Just a reminder- Ethanol added to gasoline raises the octane rating. So, this discussion proves nothing without control of lots of variables!

The debate (or 'outburst' as we saw above) over energy content of ethanol is a different parameter entirely. Pure ethanol contains 70% of the energy of pure gasoline. If blended 9 parts gasoline and 1 part ethanol the resulting product has 97% of the energy of pure gasoline.
To argue that engines operated on E10 increase their consumption by 15-20% (or 50% as we saw above) demonstrates a lack of common sense. Even if ethanol had zero energy content, E10 fuel still contains 90% gasoline, so the consumption cannot increase by more than 10%.
I suppose now someone will concoct a theory that ethanol somehow conspires to stop the gasoline from burning properly and that's why it truly is Satan.
Where's Doug by the way- he usually likes to jump in on these amusing discussions.

I also sub majored in petroleum, as this is what brought me to Oklahoma...I am not going to waste any more of my time with you or any other google driver...Think what you want, but FACTS are: Ethanal (corn whiskey) has fewer BTU's of combustible energy/unit than pure hydrocarbon based gasoline..
The facts of science speak for themselves, they don't need hillbillies from the deep south trying to explain them.
