Mine hasn't been doing too great on E10... or E5. I suspect there's a further problem or it's just the cold weather wreaking havoc. I did a test where I compared MPG figures from me plodding about when I went on a run with it on Thursday, covering around 320 miles of mixed driving. It's not really scientific, as I don't own the lab coat.

 

Average on E5 'Super' from Morrisons: 42.5MPG (02/12/2021)

Average on E10 '95 RON' from a garage in New Cumnock: 42.3MPG (02/12/2021)

 

My source is the car's built-in computer, so I cannot vouch for the accuracy of that one, but I don't think it's far off based on my approximations of range based on refuelling and trip computers.

In the UK the petrol is 'Unleaded' (95 ron min) which is now E10

or 'Super-Unleaded' 97 or 99 ron minimum. The term Premium is usually a Diesel / Derv term.

 

Using Premium or Supreme as in a reference to Petrol as in this video is just a confusion.

Bp 97 ron ,but the vrs seems to like the e10 ,or at least mine does .

Odd as they referred to Premium as 95 Ron in the past and not the Super.    BP and Royal Dutch Shell certainly know how to add premium to the cost of super unleaded over unleaded in comparison to what Tesco, Sainsbury take over the price of 95 unleaded to get 99 or 97 Ron.

Actually ime wrong come to think of it ,its actually labled ultimate unleaded,more marketing bs .

There is no BS with Octane.  The BS is extra detergents.  As to ethanol I have had cars that just love the stuff.     If the car or anyone's pocket does not benefit from using super unleaded then no need to use it.  Some might be fine buying E5 at Super Market filling stations that costs no more than E10 at a BP, Shell, Gulf, Texaco etc.  Plenty have no choice and need to just buy fuel.       Whatcar / Autocar, Autoexpress have had long enough now to do 2021 testing.   The tester of choice the UK Government use is part owned by Autocar / What car,s owners anyway. 

 

It would be a service to the UK's population to give the actual figures on emissions reduction if there is any with E10 over E5, 

and also to let the public in if it does mean more fuel used so more Road Tanker and Shipping Tanker trips moving & delivering more road fuels.

Or is it going to ultimately put older cars off the road or just doing less miles.

 

Testing like this that Teco PLC had done.
