E10 - Toyota compatibility

[FROSTYBALLS]

If your Toyota has a petrol engine or hybrid powertrain and was officially produced for European markets since January 1998, it will be compatible with E10 petrol.

The only exceptions to this rule are the following vehicles:

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

• Toyota Avensis with 2.4-litre 2AZ-FSE engine made between June 2003 and October 2008.

If your vehicle was produced before January 1998, it cannot use E10 fuel.

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. Having received queries from owners regarding specific imported models, we are investigating this further.

Since changing from diesel to petrol hybrid I have noticed that at all the stations I have used, the E5 and E10 symbol has been displayed on the same pump.

Are you looking at the pump body or the pump nozzle. The nozzles should all be labelled individually.

[Haliotis]

The pump(s) I mainly use (Tesco) have only two pump nozzles - one for petrol and one for diesel,  For my car, the handbook says both E5 and E10 are compatible.

[Strangely Brown]

Perhaps I have missed something. If you use a pump with only two nozzles, and one of them is diesel, then the handles are probably labelled E10 and B5 respectively. E5 at Tesco is Momentum and it sounds like your station does not have it.

[Cyker]

Quite often, the E5 is only on certain pumps, not all of them.

It is possible that I was looking at the pump body - will take special notice next time I visit. Have to admit, it wouldn’t make much sense for the nozzle to show two different grades.🧠

My Corolla was manufactured in the autumn of 1998, this new model came out in September of that year.  The front exhaust fitted at the factory has been modified and presumably was actually made for the earlier model, so the same could apply to other components, consequently I only use E5 petrol, better safe than sorry!

[Haliotis]

Last time I visited Tesco, one pump was covered up with a “Not in use” notice on it, although at that time I had not realised it was a third pump.

Filled up again at Tesco yesterday, and this time noticed the pumps were labelled Diesel / E10 Unleaded Regular 95octane / E5 Unleaded Premium 98octane.  My C-HR handbook shows both E5 and E10 to be compatible, so I chose E5.

According to technical information, E10 can be more corrosive - something to do with the ethanol 10% blend, compared with 5% ethanol for the E5.

[Cyker]

There shouldn't be anything in a reasonably modern car that has a problem with ethanol; The 2 main detrimental effects ethanol has is it attacks natural rubber, and draws water out of the air into the fuel.

The first thing would cause seals and rubber pipes to become brittle and crack, but most cars now use synthetic rubbers for such things which is much more resistant to that,

The 2nd thing is a big danger to cars which aren't driven often and have metal fuel tanks or carburettors - The water slowly accumulates over time and falls to the bottom, where it can slowly rust out the bottom of the tank or float bowl. Most modern cars use injectors and have plastic tanks so, again, less of a problem with them.

 

On a slight tangent, I put some Texaco Super E5 in today (~440 miles, ~26L filled! 80.7mpg indicated, ~77mpg calculated!) as part of my continuing tests, so it'll be interested to see if it makes the engine less obnoxiously diesel-like when stationary!

(Not sure if there's enough to make a noticeable difference as there should be still about 10L of normal supermarket E10 in there with it...!)

Some of our local garages do not sell E5 at all but you can go to Sainsbury's who sell both.

[jthspace]

I personally prefer Esso. Check their website for full details but at the moment they put less than or no ethanol in their E5 in many parts of the country. 
My Eunos (1993) can only take E5 but my MX5 ND can take either.  
 

On a recent run around Norfolk in the ND I got average of 49 mpg including fast run on the A14/A11. If I put E10 in, then it will be hard pressed to get much over 43 mpg for a similar run. 

I put E5 in the Yaris at last fill but I’ve not done enough miles to see what the effect is. Going on a mid week break next week around Suffolk and Norfolk so will put a decent few miles on so we’ll see what it reports. 

[Cyker]

Yeah the Esso super E5 is currently in the lead in my quietest engine competition  

[Big_D]

I sued Shell E10 when I filled up last. My GR Sport does not like this at all. Neither did my previous C-HR. I normally use Esso, and can really feel the difference.

[Mushu84]

In my area I have Jet, Sainsbury, ESSO and Bp, always used Jet petrol, the premium one in the MK4 and Mk2 Yaris that we have, I've tried Shell and to be honest did not feel anything for the higher price asked 

I still did not try ESSO but this coming days I will

The fuels have to meet a DIN rating - doesn’t this mean a uniformity that includes performance. (Mpg)?  I would have thought that this limits the fuel companies to the use of additives, with “claimed” features that do not affect mpg.

Many years ago, for a time I filled up with Clevecol, which had alcohol as an additive.  The claim was that it had a cooling effect, and compared the experience to that of how quieter the engine was on a cool evening.  I don’t think it is coincidence that all the claims by fuel companies died out with the advent of tighter advertising laws.

Yep, no longer allowed to “ Put a Tiger in your tank” ( for those of us old enough to remember the ad ! ) 😀

I must be showing my age, but I remember the ad !!
