Serious problem with E10 petrol!

[paul9]

If you have one of the Halfords stores near you, they also sell E10 conditioners. Don't know if they are any good, though. Local autoparts stores and Eurocarparts also sell the stuff.

Seems the front-man/owner of Honest John left several years ago. It's gone down-hill since.

The price difference between E5 and E10 isn't worth considering. On a full tank it makes maybe 5 GBP difference (30 L). Given it burns the E10 fuel quicker, it's a total con! The lost MPG vs. the price differential about breaks-even.

Given E10 is a threat to component longevity vs. E5 (even if they claim E10 is "safe"), it's a no-brainer. E5 all the way!

TBH it depends on the car; Older cars will run less well on E10 but the newer ones the difference seems far less pronounced. I literally can't tell the difference between Shell V-Power and Sainsburys E10 in mine!!

That's interesting, I hadn't considered the different mpg, I hadn't even noticed the choice of fuel, not being a frequent visitor to the pumps.

Never used E10 whilst we had the 2 Toyota hybrids. Now, with 2 Skoda petrol cars, I only used E10 once, and that was when I picked it up from the seller and needed some juice to get the 80 mile journey done. Then I went back to E5. For the mileage we now do the extra cost of E5 is insignificant.

As regular long distance driver I always notice a difference between fuels on each fill up. Sometimes there is a small variation in performance even if the same fuel from the same garage and pump been used. E5 though always been the better one and the engine always run better. Touching the wood I haven’t done any work yet on the fuel system, no fuel filter replacement, no injectors issue, nothing. 12.5 years and 238k miles.

Tony, as far as you know do all Esso petrol stations do the E5 99 Momentum grade????

[Phil T]

It's not available at my local, but I'm told they will have the Cooking Oil on tap soon Supreme 25% Renewable Diesel, made from used cooking oil. That's instead of hydrotreated vegetable oil. It will be like the old days, the smell of fried chips wafting down the road, one of your five a day.

Most garages has E5 99, including esso. I do prefer Tesco as the price of e5 it’s similar to e10 from bp or Shell, and it seems the fuel is good , the car likes it. 👍

I think in south of England esso has no ethanol at all , was in a car magazine where I read about it

There is a guy from uk on YouTube he compares petrols from different garages e5 vs e10 and every time he bring a new example the ethanol content varies in both e5 and e10.
Sometimes it’s just 2.5% sometimes 7.5% particularly he used Tesco fuel in one of his comparisons. I am ok with it. Esso indeed says that in e5 they use no ethanol but it’s too expensive, 15-20p  a litre for me it’s too much, i use around 100 litres a week, that would cost me almost a grand a year more. During the petrol crisis I used some esso e5 97 and the car was ok but not anything better than Tesco 99 e5, for a lot less. Cleaning additives I don’t mind as I use from time to time wynns and they work well. 👍

From the horse's mouth:

https://www.esso.co.uk/en-gb/fuels

"Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is ethanol-free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland)"

If you do very low mileage, this is the stuff to use, as it won't separate over time like E5 and E10!

 

[TonyHSD]

What would happen if you leave e10 fuel in the tank for 6 months? 
The water will separate and remain at the bottom, the fuel pump will suck that first but because it’s a fuel air mixture it won’t hydro lock the engine and tiny droplets mist like spray of water with some little bit of fuel will get into the combustion chambers and clean all the carbon build up, similar to what folks from USA we’re doing with sea foam sprayed through the air intake. 😂 What do you think? 

[Cyker]

Hypothetically? If the tank was a modern sealed tank and it was brimmed initially, the water forming might not be too bad, but I'm not sure if the fuel itself would have started to go off anyway by then - I've read that the blended fuels have a shorter 'shelf-life' the more E there is but not sure how true this is of the fuel actually going off or just water settling out and causing problems.

Partial tank fill or old unsealed/vented tank, likely more moisture would be in the tank, condensing on the walls over time and accelerating the fuel degradation as it dripped into the tank and bound to the ethanol and sank to the bottom of the tank.

The Esso E5-but-really-E0 would avoid all these problems (Apart from the going off after 6 months issue anyway!  )

My dads car is seating without any use for 5 months now and it has e10 half tank . He only start it once a month and let the engine idle for 20-30min.
He says that the car starts first time and it’s running fine the only thing he mentioned is that he will need a new Battery as his one is dead, but it was dead before that as it was swapped with older weaker one in the garage where the car had some work done previously, again horrible service experiences. I might buy some fuel additives or ask him to buy and pour into the tank.

Why not take it for a good run, Tyres and cats don't like sitting around besides the engine gearbox etc.

Dad can’t drive for some time due to a medical problems and I am only 1700 miles away. Otherwise I will enjoy having some fun in his old motor 👌

Will not touch E10 as long as there is E5 available even if it costs me more. 

Do you remember the 'fuel shortage' back in September/October 2021? Funny enough that is when the government rolled out the E10. 

[TonyHSD]

Here found an interesting video about synthetic fuels, made in England and better than ethanol. Safe for all cars.

Hi,

I'm based in Ireland and drive a 1998 Avensis 1.8 automatic. In April, the government is replacing all petrol with E10....it seems they are not phasing out E5 but instead getting rid of it overnight!

I understand from my research using the VIN number etc that my car was first registered at the beginning of January 1998, but manufactured in December 1997.   It says on the UK gov website:

 "E10 petrol is cleared for use in all Toyota European petrol models made from January 1998"

I have a horrible feeling my car cant take E10. 

Would love to get your advise, have you had a similar experience?

To be honest, I love my car......with a full service history, no rust underneath and only 140 thousand genuine miles on the clock...I cant even contemplate the idea of scrapping it!

Cleared for nearly all 1998 plus models, unfortunately I am in the very few Toyota engines that need E5 🙈🤣

“Toyota Avensis with 2.0-litre 1AZ-FSE engine made between July 2000 and October 2008”

[TonyHSD]

I have a relative that drives the same car on e10 since 2018 and he had no problems so far. I am not saying that it’s ok to do so, just sharing a story. And here is another one interesting about petrol
