Branded v Supermarket fuel

Supermarket fuel is E10 (even their premium stuff). I have to get shell v-power to have a lower E content. (V-power is E5 IIRC).

I don't think i've ever found an E10 pump in my travels. It's printed on the pump and i'm pretty sure E10 hasn't actually been introduced in the UK yet - last I saw was it was expected to arrive some time in 2021?

Edit - https://knowyourfuel.campaign.gov.uk/

"E10 petrol is not yet available in the UK. It’s widely available across Europe, the USA, Australia and many other parts of the world. Most vehicles produced since 2000 have been approved to run on E10 petrol as well as E5 petrol."

Unless your location is out of date and you're no longer in the UK, i'd say your experience of finding that all supermarket fuel is E10 probably isn't accurate :p

Correct. All UK fuel now has E5 or B7, you will have seen that many pump nozzles now have the bio content on the handle since legislation at end of 2019.

Pumps near me say E10 at supermarkets. Definitely at Tesco.
 
Shove off and find something better to do during this lockdown than being a condescending smartass all the time.

What credible reason is there to support your claim that your car only runs properly on Shell 95? It's the sort of baseless claims that circulate the internet and convince people of things like Supermarket fuel being sub standard.

How much ethanol is in Tesco petrol?

Under UK legislation, large fuel producers have a mandatory obligation to use a certain percentage of fuel from renewable sources. The renewable fuel used in petrol is ethanol, typically produced from sugar or starch crops such as sugar cane and maize. Dependent on location and supplier, UK petrol contains between 0 and 5 percent ethanol (produced in compliance to BS EN 288:2012).
 
My old BMW gets grouchy on supermarket petrol. Something that has been repeated most times I put supermarket fuel in it. So I fill it up with Shell 95 most of the time. No idea why that would be, and I'm more than open to the idea that it's just a coincidence, but I'm talking 4 or 5 times, each time after putting cheap fuel in because I have no other option at the time.

At the risk of starting a war, I don't think this is entirely inconceivable. I was told that any Bosch ECU (and I don't know what BMW uses, but VAG generally uses Bosch) would take about 500 miles of driving to adapt from one fuel to another. So if you consistently put one type of fuel in a car then randomly put different fuel in the car, it might not be just quite the same. And if you very quickly revert back to the old fuel, the car would be 'normal' again. On the other hand, if you refuelled 2 or 3 times with the 'new' fuel the car would adapt and become 'normal' again. I believe this is why they reset the ECU's on cars they use in fuel economy trials when testing different fuels.

So may be possible that someone could feel their car was a bit 'grouchy' on fuel from a different source.

That said, I think all fuel is basically the same and I use whatever correct spec fuel is cheapest in the area when I need to fill up.
 
Why does it say E10 on the guns at Tesco Holmbush petrol station then? Have they just put the new stickers on ahead of time?

And I put Shell/BP/Esso/etc in it, when I use Tesco petrol it is slow to fire off and sometimes gets a case of the kangaroos before its warmed up.

Maybe it is a coincidence, but its happened only when I've put cheap petrol in! I'm just sharing my experiences.

It does have a fairly basic Bosch Motronic 1.3 fuel injection system being an old car so maybe it has something to do with what WJA96 is saying above?

The previous owner always ran it on supermarket fuel and didn't have issues as far as he said.

I put a few tanks of VPower through it when I first got it and then went to branded 95.
 
The other consideration is ethanol content too. Supermarket fuels (in my experience) have a higher ethanol content. For those of us with older cars (my Westfield engine is from 1974!), ethanol = bad. Supermarket fuel is E10 (even their premium stuff). I have to get shell v-power to have a lower E content. (V-power is E5 IIRC).

Ah very interesting to know - being a youngster I’d never considered it :-)

Thanks for the info! :cool:

They've either put inaccurate labels on their pumps denoting that they're supplying a fuel grade that they're actually not, they've introduced E10 while the government is still running consultation on how best to implement E10, or the labels say E5 and people are remembering incorrectly because the E5 labels only appeared toward the end of 2019 in the first place on a lot of pumps.

Here is my post on it, and still people don't seem convinced. I tried to be vague but I actually work for BP at our technology centre that develops fuel and engine oils. I'm tired of trying to hide it :)

I was the technical expert on the Geneva stand below.

Thanks for this - very interesting

Just want to understand fully

The photo with the brown/orange engine is using premium, and the silver engine using supermarket?

Based on your photos, which is the better one? And what is the cause of it?
 
I switched from Shell V Power to Tesco Momentum 99 some months ago, and although I don't know the exact difference in additives between the two, the only difference I've noticed whatsoever is that it's lighter on my wallet.

I'd be happy for someone like @Simon to tell me whether V Power is actually worth the extra though :)

This is my experience, couldn't tell the difference between either diesel or petrol in my cars.

Hi,

They aren't great photos sorry, but very powerful in real. The brown is the half of the engine that ran basic EN228 specification fuel, Silver is using the Branded fuel with much more additives than the EN228 specification require. The benefit of the cleaner engine is that the intake valves and intake system is much cleaner, and keeping the engine running properly. Engines may get dirty but the average drive wont notice the degradation in performance. Also the emissions are much worse when the engine is running less efficient. This is wy people use the famoud line that they don't notice, no one is good enough to notice these changes but they do exist. Things like high pressure pump failures can be reduced with better fuels.

Onto diesel now, one of the big failure modes is injectors, this is caused by deposits inside the injecter and fuel has a huge impact here. its never mentioned though as Doris 'cant feel any difference' with the cheaper fuels using minimal additive treat rates.

injector foulind also cause issues with increase emissions. its why DPF loading can be higher on vehicles using cheaper fuel. First thing people will do is complain about the car and its DPF blocking, and at the same time they mention they notice no difference in how their engine runs.

Often the better fuels with more additives do impact your car and engine, but don't be so naïve to think that if you don't notice anything then it cant be doing something. Direct injection gasoline is a good example, in markets like China with there fuel. The difference between fuels can result in 40x more PM2.5 emissions, the drive wont notice the difference because they aren't sensitive enough to the small changes in the engine, but the atmosphere certainly will. If this car has a GPF fitted too then the GPF is going to fill up much sooner.
 
Apologies in advance if this happens to be an old and worn out topic of conversation, I don't come into Motors a lot.

I mentioned in another thread that I was advised not to use supermarket petrol on my Auris because it can mess things up like electronics, plus...branded fuel can give more MPG. I got this response.

What Auris is it?

if its a hybrid it wont make any difference as it uses a atkinson cycle engine rather than otto
