Filled up with E10 bog standard unleaded (no EcoMax added) from Shell, after getting a whopping 416 miles out of a tank of Super Unleaded with EcoMax in.

 

Had 30 miles range when I refuelled and got this on the range display! 

 

(And yes the 🤬 oil sensor is kaput again hence the yellow oil can.)

That is because it has just based the quantity of fuel you have added and your previous driving characteristics and estimated 420 miles.

 

Once the E10 goes through, things may well change, as it adjusts the timing etc or whatever it deems necessary to cope with the fuel it is getting…. IMO.

 

Someone more knowledgeable may give a better answer.

 

 

@TheWanderer I pretty much agree with @Defenderben with the note that the fuel level may not have sorted itself out right until you leave the car overnight.

It was still showing 420 miles this afternoon after standing overnight. Weird! 

Until you start driving again the system has nothing to calculate the estimated range against apart from the data stored from your previous tankful.

Well it's taken 10 miles off now, but that's not entirely surprising as I drove 9.

What difference were you expecting after filling with E10?

 

Depending who you believe, it may drop your MPG by 1-3%, that's between 4 and 12 miles a tank less. Having some fun on a nice day will probably make more impact to the range

  Seriously, I'd expect an effect from a chemical change in the fuel like this to take more like half a tankful to show up.

OK. Mr K.

 

I'll let you know how far I get with it.

You will get less MPG from E10. It's not as energy dense as E5, so more fuel will be used for the same power. Can't remember the figures of the top of my head, E10 is about 7.5% less energy rich than E5.

 

All the more reason to fill up with V Power

It gives an estimated range based on current fuel level and recent average MPG.

 

From the manual: Range - drive distance in km which can be covered with the existing tank capacity and with the same driving style. If you drive more efficiently this value can increase.

 

"With the same driving style" is the key phrase - I seem to recall reading somewhere it uses a 'rolling' last 50 mile average MPG or something like that (and I don't believe this can be reset, it's a 'hidden' figure, unlike the three averages you can display).

 

So if you do a super eco 50 mile run, downhill at 56mph with a tailwind and then brim it, it'll give you a fantastic figure. If you rag the absolute balls off it for 50 miles and then brim it, it'll give you a very pessimistic range.

I don't think it's anywhere near 7.5% in terms of energy.

 

E5 is typically 31.5 mj/litre, E10 is 30.9 mj/litre.

 

Frankly, without specifically measuring for it, I doubt most people would have noticed a change in fuel economy if the swap to E10 hadn't been publicised.

Yeah apologies, getting my values mixed up.

 

But as you say, the average motorist won't notice. The petrol companies have only told people to cover themselves for when someone fills up their old 2 stroke bike or old car and it causes fuel system trouble

Not at £1.51 per litre.

Yeah, it's expensive.

 

I'm on a bit of a road trip next week and as i don't normally do a lot of miles during the week, i thought I'll treat the motor with some Shell unleaded - wrong - no normal unleaded at any of my local Shell stations. so, V-Power it is then. The bonus is that V-Power is still E5.

 

The wife has a 1.2 TSi Polo, that would usually get 60-65mpg on her commute, it is now mid-high 50's.
The last E5 tank returned 460miles, the last E10 tank returned 430miles so around a 7% decrease; it is too hard to attribute how much of that is down to the fuel alone.

 

If my math's is right, E10 probably works out to around £4 per tank 'more expensive', premium unleaded is around £8 more expensive per tank. 

 

 

 

 

So a price hike on the sly.

How much!!!! God, I know things are a bit more expensive down Saff, but I filled up with V Power diesel last week and it was only £1.48. That's always a few pence dearer than the equivalent petrol V Power.

 

This is a bit of a toss up of things now. Do people wish to pay for the 'standard' e10 fuel, get slightly less power and slightly less MPG. Or, pay for the 'Ultra' E5 and get better power and more MPG, plus with the added benefits of snake oil has to offer.

 

We would struggle to do it in real world conditions, but I'd be interested to see what the mileage from a tank was and the performance on a dyno if we compared E5 95 RON vs E10 95 RON and E5 98 RON. 

@tunedude

Your idea of a few pence is different from mine.  

 

Others Super Unleaded might be a few pence more expensive than their Unleaded, like 5 or 6 pence a litre, so £2.25-£2.50 a tank more.

15 pence a litre more is certainly not a small amount.

 

*No retailers have sold 98 Ron in the UK for years since Shell went from V-Power to V-Power Nitro+ and BP & Gulf went to 97 ron instead of 98.*

 

 

................@TheWander

Once you know how the E10 fairs and if any difference which really their should not be no mater all the 'myths' on less energy from the 95 octane fuel with up to 10% ethanol.

Cars love Ethanol as long as not standing long times, or with crappy rubber components.

 

If you do want E5 then Tesco Momentum 99, (99 ron min),  Sainsbury 97 Super Unleaded (97 ron min) is perfect, 

no point giving Royal Dutch Shell more profits buying their V-Power Nitro + (99 Ron Min) that comes in as the Same base fuel as Greenery import with them for the 

Tesco Momentum, or ESSO Synergy Super Unleaded (99 ron Minimum)

I try to use JS SUL (97) with a 50ml shot of EcoMax which if correct makes it 99 octane.

 

Might try adding EcoMax to E10 and see what range I get on the VC.

I was meaning in the price per litre, not price per tank

15 pence is not a 'Few'  in my world. 

45 x 15= £6.75 a tank extra.   More than the price of buying a gallon / 4.546 litres of go go juice at the pump many use.. 

 

 So i would want 35 miles a tank extra from V-Power Diesel, or much better performance if driven hard, or smoother driving.

 

As it is the Shell standard DERV

or 95 ron Saver Unleaded is overpriced before you get to adding more spending on their Premium Diesel or Super Unleaded petrol.

🥱 yeah alright. You've not understood what I was saying. But we'll leave it there eh?

do you really notice the different with standard fuel when you add things like EcoMax? I assume it's a bit more of an improvement than adding something like Redex power booster.

@tunedude

Lets ignore the Few then.

 

So do you think there is a benefit to you running a TDI on Premium Diesel over standard Shell Diesel or any others including supermarket, and do you pay for your own fuel?

Is it better performance and fuel efficiency you get with the Premium Diesel which has no higher a Cetane? 

I've tried using bog standard 95 and get about 320 miles, add EcoMax to 95 and range goes up to 335-340.

 

A standard 97 will give me about 360 add EcoMax and it goes upto 370-380.

 

So imagine my surprise when putting E10 in I saw 420! 🤔
