E10 fuel from September 2021

[Bryn]

I contacted Toyota as I've a 2.4 Alphard coming soon manufactured  2011. I also asked about fuel suitability for 3.0 and 3,5 engines .The official Toyota response is as follows... 

'I understand you have a Japanese imported Toyota Alphard and would like to know if it will be compatible with E10 fuel. Toyota's official advice on Japanese imported vehicles is the following:

If your car is an imported model that was not officially sold in European markets, we recommend staying on E5 by using super unleaded, which has a higher octane rating.

This information can be found using the following Toyota FAQ webpage:

https://mag.toyota.co.uk/e10-petrol-what-is-it-and-can-i-use-it/

We would suggest keeping an eye on the webpage for further updates and use E5 fuel in the super unleaded grade for your Toyota, which is available at petrol stations.

Thank you for sharing this information, we’re picking our Alphard up in a few weeks, can’t wait to get on our travels!   Been reading quite a few comments on E10 & as per the advice from Toyota we will use E5 and carry an E10 additive in case of emergency!!

I’m purchasing a 2008 Alphard being imported from Japan. Does anyone know if the vehicle is compatible with E10 fuel? 

Have just recently purchased a Alphard 2003. We were told NOT to use E10, preferably E5 is the best choice

[Rojie]

There is loads of info on E10 on this forum.

 

Like the rest of us, you get to read it and make your choice.

 

The safe bet is E5.

Hi not going to promote the company I work for but I work for a local well known motor factor's who specialises in Japanese imports we sell lots of parts for the elgrands and alphards one of our main customers in Southampton a regular known garage tells us he is getting a few alphards coming in now with problems due to fuel issues he tells us ecu light coming on he tells us it's because the ecu is programmed to recognise hi octane fuel he says e10 fuel no good .

[Rojie]

I don't disagree that E5 is the preferred fuel. Nor do I disagree with Picasso.

 

However, what is interesting is that Cuttothechase (on youtube) has put up a video which purports to show the ECU adjusting the engine settings when fed E5 / E10 fuels.

I can find no reason to question his findings !

If I understand his findings correctly, he finds the ECU adjusts to the fuel the engine is fed. (He does not, as I remember, speculate on long term effects of either fuel).

 

What is of most interest to me, in the above case that Picasso cites, is what is the corrective action that the vehicles need.

(Hopefully, not the O2 sensors).

 

if you wish for further reading,, I have already provided two American studies on the use of Ethanol fuels. Should you be interested please search my profile.

They may, or may not, help you consider the risk of using higher Ethanol fuels.

According to the Toyota Alphard Handbook that came with my 3.0 V6, Super Unleaded is the recommended fuel.

Hi Gag,

 

Yes. this discussion is about which unleaded to use.

There are two. E5 which is the old Super Unleaded.

It's expensive, but should be risk free.

 

The other is E10, a new fuel introduced in September 2021.

There is a large difference of opinion on whether this fuel is harmful to engines and or engine accessories in the longer term.

I use E10. my 3L is still doing 30mpg on long runs, running smooth, engine oil looks ok, and premium e5 appears to be in v short supply locally with many garages out of stock and most of the supermarkets don’t stock it at all.

[Gordio21]

HI Wjvh I'm also on e10 and it seems ok on my 3L can't do mpg because I'm still nearly full. I only do one mile and it switches to LPG. I'm getting around 420k to a tank @ 77.9 per ltr. Let you know petrol miles when I fill up again. Good luck. Gordio

If you are running on gas most of the time it should not make any difference. Should it ?

 

It might.

 

I have read that E5 (many of which have no ethanol at all) is less likely to separate in your fuel tank if not used for long periods.

If water (moisture in E10) does separate out, it can cause issues.

Wish I could remember what issues, and where I read it !

Cheers Rojie I'll Look into it I know I had 1/2 a tank of e5 and topped up e10 so I'm 50/50 at the moment. So after reading your tweet I've decided when I reach 3/4. I'll top up with e5 which we still have in my area. Thanks for the heads up mate take care. Gordi.👍👍

@Gordio21 420 miles or km per tank?

I usually get 600km per tank = 373 miles. Looks like current tank is gonna give me 700km = 435 miles. (No canoe on roof!)

 

my old motorbike runs fine on e10 but it can sit for weeks without being used and e10 fuel goes off much quicker than e5. And with 10% alcohol in it the e10 draws more moisture out of the air into the fuel, this then condenses in the fuel and sinks to the bottom of the tank where it can cause rust and other problems. So if fuel is going to sit around for a while go premium! I try to put e5 in my old bike if I can find it.
E5 is up to 5% alcohol, often it is zero alcohol. Whereas e10 is definitely 10% alcohol.

[Gordio21]

Wjvh. Are you talking lpg  or petrol my lpg is only 420 km per tank so if your getting 600 I'm what size tank have you got.

[wjvh]

@Gordio21 my figures are petrol, I haven’t converted to LPG ….yet.

standard tank which is 60 litres I think.

 

65 litres, I just googled it, sounds about right. I usually fill when empty so about 60 litres each time (13.2 Uk gallons) from Which I get 600km, maybe a bit more (about 372 miles), so that’s about 28mpg. Getting more now the roof bars and canoe aren’t on.

[Gordio21]

Yes I thought you must be talking petrol. I haven't yet checked that. My lpg tank is 97 ltrs but get a warning bell at 80 and that's when I top up so I assume if the other 17 were used probably get around 500. Take care Gordi👍👍

[OldWellhouse]

For the miles I'll be doing I'm gonna try and only use the premium. An app that shows fuel stations that still have it would be helpful but it seems to produce results on a google search.

We’re in the same position, it’s very concerning that the Alphard is not E10 compatible.  I’ve been reading up on this, E5 is ok to use but it will only be available for 5 years… then the Gov will decide if it remains on the forecourts!! 

Yeah e10 no good for alphard import I use the super unleaded e5 expensive but runs like a dream and quite good around town too mpg
