They are really good,

near 100 ps less than the sporty fast models and yet get you about in the UK just as quickly and at less money spent on fuel.

 

It's quick enough for me to be honest, especially if I put it in sport mode. Our other car is a JCW Mini so I just drive that if I fancy having some fun 😀

Just got 320 miles out the tank, still showing 125 available (really?) when I arrived back from Warwickshire yesterday, however with the current situation with fuel I didn't know where or when fuel would be available locally, so topped it up at 115 miles available by the time I got to JS in Godalming. 

 

So still really none the wiser about E10 or the cars computer accuracy. 

If you are adding octane boosters then knowing about E10 is not straightforward. 

Why is it that you do not use super unleaded so E5 99 ron from Esso or Tesco rather than Shell V-Power Nitro + ?

 

?

What is JS SUL (97) ,     

  Is that Sainsbury's Super Unleaded which is a minimum 97 ron,

but can at times exceed 97 ron?

I don't use Shell V-Power Super Unleaded because of the extortionate price. At £1.51 per litre that's not in my price range.

 

That's why yesterday I declined to use Oxford M40 services like the sheep and took a chance on getting home on what I had and did with arrogant ease, mind you that was bog standard unleaded at that price! 😲

 

I don't have a Tesco with a petrol station attached to it. The nearest being Aldershot or Broadbridge Heath, so unless there's one on my route it doesn't come into consideration. 

 

I filled up with JS Super Unleaded today at £1.41 per litre today. Hopefully that should last me at least 10-12 days so the panic will have subsided. 

Out of interest, just because I've googled Ecomax and wasn't really sure which one it was, how much is said product and what's the quantity needed for a tank?

EcoMax Petrol varies from month to month, about £14‐15. One shot is 50ml per full tank, so a bottle is 10 tanks.

I'm very near to you so the same petrol station comments apply. I usually use BP or JS 97. Sometimes Shell 99 but not at these prices.  I may try the Ecomax additive if it really works with 50ml... edit. Last fill the wife put in 95 as that was all that was available......

It adds about 20-30 miles (according to the computer) range with super unleaded. So from 410 to 430 miles range.

 

I'm also running around in Eco mode to try and extend the range even more. 

"According to the computer"?

 

Surely you mean the odometer, that is to say that you have driven 20-30 miles further on a tankfull?

 

The predicted range on the dash display will not change whatever fuel you have just filled up with, the vehicle does not know what fuel the tank contains, you could fill with tap water and it would show the same range as had you filled with diesel or petrol.

The whole conversation could soon be moot given we’re only 10p a litre away from the OP being priced off the road. Probably a couple of months 🤷🏻‍♂️

Ha ha.  Me too though!!!. Lots of inflationary impacts starting to creep in. Not just fuel.

True as far as it goes. However the predicted range mode varies with driving style and terrain as well as fuel tank contents. I have driven 26.5 miles (source Bing) and my available range has risen by 20 miles at trip end (source Skoda). The terrain was the variable.

On more than one occasion with my previous RS4 after filling up I could drive for up to 100 miles and see the predicted range be greater than when I started - how come?

 

Because the previous few days had been rush hour stop-start traffic on the M27 commute to & from work so the predicted range was based on a fuel consumption of around 15mpg, but I was actually driving at a steady speed on dual carriageway and motorway with a fuel consumption of around 25mpg.

 

The predicted range assumes the driving conditions will be the same after filling up as they were before filling up, when this assumption isn't true then the predicted range is meaningless.

I don't know about that. It does most certainly know the difference between bog standard unleaded and super unleaded (Tesco 99 / JS 97) as the range is different between them when I fill up.

Lets be quite clear before I bang my head against the wall, are you speaking of the range showing on the dash display after filling up or the miles you had achieved on the previous tank of fuel?

 

If the former tell us by what means you believe that it can possibly know?

He whispers, tenderly, into the fuel neck which one is being used just prior to filling up. 

And "I promise that I will pull out in time"

@TheWandererYou have had nothing but trouble with your car have you not, it could not actually be running right finally could it?

 

Have you happened to increase your tyre pressures recently?   

 It is ideal weather for getting good fuel economy, not too hot, not too cold, just right mummy bear.

 

Maybe just right conditions for less fuel wasted by the GPF.

Engine internals clean enough to eat your dinner off.

 

If they try try and try again they must eventually get things fixed and the vehicle running as meant to.

Reading this and seeing those figures reminds me of why I do not miss my old petrol performance cars. Seeing 15mpg again on my dashboard would give me nightmares. I now prefer to see 50+ happy in the knowledge I am not wasting my money on fuel like I used to. My old MK1 Focus RS was very thirsty and only got 230 miles to a tank if I was lucky. Meant I was putting in £45 (back then Shell Optimax was just hitting 99p a litre in 2003) every 4 days as work was 50 miles round trip.  Now in comparison I pay about £60 to fill the tank from empty but can easily get 500+ miles to a tank.

There is not a choice of holes to my knowledge

Some are not aware of the little button you push and that allows you to get more in.

 

Some even push it by error when inserting the nozzle and that has more filled up than they expect. 

 

 

(be aware of Venting and the risks.)

Edited 29 September, 20214 yr by e-Roottoot

I am unaware and not much the wiser from the fuzzy photo, I will be able to work it out though at the next refuel, what do you push it with, the nozzle?

A finger or thumb is usual.    

You might slide it along where a car has one in error with the nozzle and end up venting a petrol car, then thinking how did i get so much fuel in.

It does seem to be running correctly, albeit with a water pump open circuit fault. Whatever that is!
