From September, filling stations will switch to E10 petrol and only super unleaded petrol (E5) will be available.
E10 has the potential to corrode brass, copper, lead, zinc, rubber, plastic and fibreglass, all of which are commonly found in older vehicles.
Studies show that even vehicles built in the early 2000s may be negatively affected by E10. These drivers have been warned against using E10 to fill up their vehicles until it has been confirmed that it is safe to do so.
Will the MR2 be compatible with E10?
After checking the link below, it seems as if the MR2 will be OK to use E10
https://check-vehicle-compatibility-e10-petrol.service.gov.uk/manufacturer/Toyota
Maybe a good idea to look out for any other info regarding any possible issues ...
This is not good news at all, for all the reasons in the clean fuel thread.
I will wager now. People will see a decrease in mpg. They (you) will be back at the pump another 5% earlier than you would have been.
I have to run on super anyway so no difference there. Though I expect the price to be massaged.
I wonder if the e10 will be 5% cheaper as in contains 5% less fuel.
Raised eyebrow emoji.
MR2 will be fine. People run it on E85 elsewhere.
Luckily for us.
Not fine for our final power output and efficiency.
Maybe with e10 is might be better to run 2zz injectors...

MAF mod revival ;-)
E10 has been the standard in the US for a long time with no issues, even in older cars. As for fuel mileage, ethanol free fuels are available (for a premium cost and very hard to find) but other than a few anecdotal reports, most people have reported no significant difference in fuel mileage. We tried a couple tanks of ethanol free, and saw no difference at all in mileage or performance. We did see a reduction in the wallet as it cost more.
E15 is fairly common in many areas and is approved for cars built after 2001, but we have never tried it.
If you want to learn about a fuel additive that did cause problems, look up MTBE. It was fairly common in the US starting in the late 1970's and required a lot of fuel system changes. If a car could handle MTBE, ethanol blends were no problem at all.
It again is all about the use, how you drive, how sensitive the driver is.
I définitely notice the difference between E5 and E-free.
Have méasured a definite difference in mileage.
The difference with E10 will be twice that that because it is simple the difference in caloric energy/ kg.
Whether one thinks it worth the extra money and/or hassle is a personal choice. The difference however is real. Simple chemistry. No way around that. The rest is denial and/or choice.

Haha I like that; "denial or choice".

@Ardent has done us the favour of "proving" that it indeed results in lower fuel economy. But that makes sense. As you say, simple chemistry.
I fill up on a pizza a lot quicker than the same amount of "weight watchers" food.
It is what it is. The world we live in
Our cars like most modern era cars were designed with ethanol blends in mind but much older cars were not.
Having said that ethanol blended fuels has ruined the fuel lines of my older small lawn equipment but not the newer ones that was purchased because they build them for the kind of issues encountered with ethanol.
The damaging effects of ethanol is still there with phase separation and all kinds of other things if you keep you car long enough so I now add a ethanol treatment with every fill up and before my car goes into storage.
I use something like this.

First things first.
I freely admit I talk from a point of belief, than actual indepth knowledge
But as a starting point.
How much of an issue is it, that, as I believe you have a few different grades of fuel.
We have 95 RON (lowest) and 97 and above.
I understand some of yours are lower than 95. 87?
Our cars (european) spec require 95 or above.
So not sure how well they can be directly compared to U.S.? US? spec.
Could well all be in the ecu.
I do know. My 2 is much happier on 0% ethanol.

The US uses a totally different rating their 87 is roughly our 95 I believe.
Their gallon is different to our gallon as well as I believe, hence they get less mpg.

Correct but the difference is not thát large, more like 90/91 to our 95 and the root cause is a different manner of testing.
There is MON and RON in most parts of the world whereas USA and Canada use AKI.

I see quite a bit of chat around E85 just now, UK based enthusiasts trying to make it more freely available over here. Some big power gains available if the car can be mapped to it. Not for the casual daily driver, to be fair.
All the tests I see relating to E10 are focused on efficiency, with varying results. But if you tune the engine to make the most of the extra oxygen content, there should be some performance benefit.

I posted a link to that some time ago in the search for more power by any means not subject to homologation.
Changing the mapping is a bit of an issue with the Toyota ECU.
E85 is like oxiginated RON 103 so yes, the engine can also cope with a lot higher c.r. too apart from having more oxigen in the fuel directly.
Thanks for reminding me about 103 octane; kéép forgetting to drop by the local ´airport´. Not for the MR but for the classics as alternative additive.
More E10 talk, less sniping please.
Let's keep it clean. Above the belt. No blows to back of head.
This was going to be a lengthy post, but decided to simplify my questions.
Apart from mpg and performance, are there any real known damaging effects for our '2s (or any cars), or is this all conjecture? If the governments information suggests that most makes/models are cleared for using E10, then we shouldn't worry, right?
According to that government link, my Hyundai Coupe is cleared for use, but the owners club has just informed the members to NOT use E10 under any circumstances in any of the models.
Might be too early to know for sure.
Being able to run on it, is one thing, complete with lower mpg and performance.
Good for the system as a whole, is another.
Most concerns, seem to revolve around seals etc in the fuel system.
Lots of stuff out there, that gives cause for concern. Only time will tell.
Covered a lot in the bike world, fuel tanks deforming, garden equipment all sorts of places.
If stored over winter, best to drain or at least put some proper fuel in.
Ethanol evaporates leaving a crystalline residue.
Check youtube
Building Spanish galleons increased global temperature as they cut down thousands of mature trees.
Never mind September, it has started already. Just been to juice up Alexa and there it was. (sains)
Maybe we could start some sort of our own table. To compare E5 mpg with E10. 2s and/or dailys doesn't matter really, going to get stuffed either way, just interesting to know by how much.
Some may know, I keep an mpg log of any car, not just the 2.
The 2 will only be ran on Super anyway, (because it has to) for the daily, Lexus CT200h
The last fill up was 20.12 litres and covered 240 miles, before the refuel light came on.
(using 1gal = 4.54L) MPG 54.16.
Have just put in 20.14L of E10.
As the old TV show BANZI! used to say. Place your bets now.

1-2% up from E5.
Ah well, only 1-2%.
On top of the 1-2% of E5.
Oh and it´s that much down on power as well; so a handful of horses gone awol on the 1ZZ. Like it had the stable overpopulated...
Putting the two together:
Because the ethanol makes for less horses, the ones left need to work harder for the same performance. To do that they need to be fed more. Simples.
@PetrusYou can tell a 1-2% drop in power? That equates to approx 3hp. I wouldn't have thought that would be noticeable.

A passenger or full tank vs 1/2 tank vs empty is noticeable.
I'm sure people will notice a trip to the pumps 1-2% sooner.
@Petrus works on a diff set of scales to me.
I view this way. What was actual fuel, now isn't, another 5% less than what was already 5% less than optimum. Hence E10. 10% of what you put in the tank is not proper fuel. I view it as a bulking agent. It may well burn, but it just ain't the same.
As I have said many times, when putting it in, that is one thing. Move down the other end of the of equation where it comes out again. The injector.
100% fuel vs now 90%. That is going to be noticeable.

Remember; it is times 2 as Jason explains.
So say 5 - 6 hp.
And yes you will notice that. Well, I do.
A different comparison as Jason makes is weight. We have say 130 hp/1000 kg. That is 1,3 hp per 10 kg. and do not tell me you do not notice 40 - 50 more or less.
Wikipedia: Ethanol fuel (https://en.wikipedia.org/wiki/Ethanol_fuel#:~:text=Ethanol%20contains%20approx.%2034%25%20less,compared%20to%20burning%20pure%20gasoline.)
QuoteEthanol contains approx. 34% less energy per unit volume than gasoline, and therefore in theory, burning pure ethanol in a vehicle reduces range per unit measure by 34%, given the same fuel economy, compared to burning pure gasoline.
So, comparing E10 to regular (read 100% and NOT E5) fuel, taking into account that ethanol is 66% as combustible as regular fuel is:
90% fuel + 10% ethanol -> 90% + 6.6% = 96.6%
So, you are only going to lose 3.4% overall. Or 1.7% compared to E5. And these numbers can be used to refer to MPG or HP, that is, either 3.4% less economy or 3.4% less hp.
These numbers are smaller than the ones that have been suggested. And all tests should use the same scenario, for example, no passengers, a full tank of petrol with no mixing of fuels and a consistent driving manner.
Ive not seen any E10 marked pumps yet all still E5 on them from what ive used, but i have noticed in the past few weeks petrol is smelling different? so wonder if the E10 is already being put in the tanks, most noticeable on my motorbike but have noticed it when fueling the MR2 as well.

The only thing I can think of is, given the ethanol is added at the fuel depot, it's been delivered by accident. I've worked in petrol stations in the past and that does happen. Unfortunately, you don't find out until customers complain their cars are running badly.
If the price is the same as E5 and you're happy to have E10 in your car or bike, I wouldn't worry.
To further my last comment about wrong fuel deliveries, another thing that happens at stations sometimes is they may not have enough space in a tank for the delivery they requested. Orders placed by stations is based on predicting sales which doesn't always quite work out. So a particular grade of fuel will be split across 2 or more tanks so the delivery driver can go back to the depot empty. This can mean that a higher grade of fuel is put into a lower grade tank, so you (as the customer) are always purchasing a minimum grade of fuel but never lower.
Whether or not a station will take a grade of fuel that it doesn't advertise for sale and mix it with a lower grade, I do not know. But I doubt it.

It does smell differently. Same when lead alternatives were added.
As was observed, the ethanol contents is on the most volatile side of the mix and it changes ´fragrancy´ accordingly again.
@fawtytoo 3,5 - 4% less weight or more power or more fuel economy is more than most marketeers get to haloo about for a new model launch, so the loss of such is no mean thing is it?!

Hmmmm. Not sure I follow all of that logic. They never have a surplus of the lowest grade? Or do I read something wrong?

Whichever way we choose to present the numbers. The end result is the same.
Less mpg. Less power.
Anything Less than optimal is not good. We are now further away from optimal than we were.
On the smell front. Did not notice when putting. But have noticed a diff smell when following others.

It's not meant to be logical. It's predicted, and as such, the station will avoid ordering too much of the lower grades (across a period of time, e.g. weekly) in case it won't fit.
My local Sainsburys has E10 on all of the Unleaded pumps but confirmed its still E5 until September. I filled up on Tuesday.

Yes noticed that as well following people, main place i notice the smell now is opening garage and i keep checking for fuel leaks on the bike but there isnt any!, yet inside my garage smells very fuelly and sweeter smell which im sure is more ethanol content but its a guess without testing it.
Also i drive past a BP garage everyday going to work and never used to really smell the fuel but now i do, something is going on im sure.
For those worried about lack of power/economy etc just put the "good stuff" in, as in Super unleaded as apparently all 97+ octane SUL fuel will remain E5, that said i doubt anyone will notice the slight difference in E10 day to day in an MR2.

I'm more concerned with the price. If E10 is cheaper to produce, then that saving should be passed on to the consumer.
For those that it's already available to, is it much more expensive?
We have been using 10% ethanol for many years without any issue in modern fuel injected cars. The problem occurs with cars, motorcycles and older lawn equipment that uses a carburetor.
You should not notice anything dramatic except for a decrease in efficiency but if you store your car seasonally I would recommend using a fuel stabilizer. There is also phase separation issues where the alcohol will attract water and I have heard that it can be highly corrosive to your gas tank. There have been a few owners that bought questionable used examples of our cars and had to have the tank replaced. This concerns me so I use a ethanol additive with every fill up.
I hate the stuff as it made an older motorcycle gum up the jets when it sat in storage and was a pain to clean out. It has also ruined the fuel lines in my lawn equipment where it became brittle and cracked. The new lines that I replaced them with is made of a different material that resists this issue and most modern equipment takes this into consideration and no longer have these issue but it is too early to tell.
I think the idea of adding ethanol to fuel is asinine as its mostly political just like energy efficient appliances that has endless service issues.
This year I plan to find an ethanol free pump before the season ends because I am terrified of the prospect of having to replace the tank.

Slightly, well quite a lot of the main topic, but right on the smell part. When exhaust Catalysers first became a thing on cars, apart from some catching the grass alight, there was a smell of bad eggs when following a new car.
Not noticed that for a long time now, so what happened with that?
Sulphur smells like bad eggs. Petrol has reduced sulphur these days.
Mini update.
Went back to the fuel station to enquire if E5 or E10.
As luck would have it.
They were taking a delivery. Had a quick chat with the tanker driver. Currently def E5.
He confirmed change over September.
Sulphur in the old days would have likely been of a mercaptan type compound they stink to hell and are used as the stench in natural gas. Rotten eggs smell is almost likely to be H2S Hydrogen Sulphide caused by a type of rotting organic material - sewers etc unlikely to come from fuel. A common cause of H2S was burying plaster products in municipal tips with household rubbish.

Was a bit tongue in cheek tbh.
The VERY loose logic being that the 2zz injectors flow more fuel per pulse. So it would compensate for the lack of "combustability" e10 brings compared to no ethanol.
