So by using that same logic would you see a 27% drop between running E5 and E85?
To run E85 you generally need to retune your car so it is hard to do like for like. People generally tune for power instead of economy. But yeh, 30% is about right.

The same, I drive with my MPG monitor always active and I always watch what I'm doing to avoid waste.
I have autism, and I'm weird with numbers.. I can literally see the difference in the MPG monitor running E10.
All urban, on both occasions, my car is only used to commute to work and back so my mileage each week remains the same. As I drive watching the MPG monitor and being very careful with my right foot. I know that a difference in driving style is not a possible reason for the difference I am seeing.
I did top up last night with £10 of E10 to an empty tank and noticed lower MPG this morning.. I know there's still some other fuel in the system but the majority is now E10.
When I said 'topped up with E10' what I should have said was car was ran till empty and I put a full tank of E10, as that's what happened with both of the FULL tanks I put in.
I'm working this out on the obvious differences I can see from the trip computer when either fuel is put in. On every tank I reset all trip computers IE average speed MPG and monitor what I achieve for the following month. This is how I know my differences are not due to driving style as that doesn't change.
I said it was an anecdotal experience and should be taken as such, that said, I have a predisposition to believe real world experience over lab results, given my complete understanding of how corrupt both humans and our energy industry is!
Well.. I don't really want to go into it too much, its all very personal you see! I'll just say I've had a much harder life than practically anyone I know, I've spent more Christmas' and Birthday's alone than anyone should, I have no reason to pick myself up each day but I do, and not only that, but in spite of everything and everyone I lost, I achieved my childhood dream of becoming a K1 world champion.
When I say you'd respect me, you would, because my presence would intimidate you as it does all others. (even fighters and sparring partners)
We aren't all built the same!
Have a great weekend <3
EDIT. For what it’s worth.
Both tanks of E10 got me 210 miles. Before the switch I was getting 280 miles per tank.
But sure, despite my experience with cars and driving, it’s probably just the weather!
I almost always use Momentum 99 in my car, but Tesco didn't have any (on two separate days I visited) so I put in £20 of E10 last week, from empty.
Totally unscientific, but fuel economy appears to be a bit worse, performance and "smoothness" is worse and acceleration is quite sluggish and not far off how the car felt when I had issues with the turbo. This is in a 2014 Seat Leon FR 1.4 TSI so it's a modern enough engine.
3.6 mile portion?
You see there are loads of things that could severely affect such short journeys. How cold is the air temp? Cooler air temps are actually good for the car once warmed up. Even slight differences in traffic. Is your alternator working a bit harder from one run versus the other to top up the battery? How does your car react to 99 ron fuel?
My mpg doesn't stay the same from one 500 mile section to the next and can deviate by up to 10% even for the journeys made up of the same commute every day. I use odometer and fuel filled as the proper measure as the car computer is terrible at estimating mpg.
What people aren't doing are properly controlled large sample tests and that is why nothing I've seen is convincing.

Worth noting that while Super is marked as E5 on the pump it's only an "up to", a number of brands (I.E ESSO) have Ethanol free Super so the MPG advantage over E10 will be even more pronounced.I only use E5. Probably won’t be long until they dilute that even more.
