E10 Fuel

[Arman]

Hi,

Can we put E10 fuel in 2007 prius?

[FROSTYBALLS]

Yes.

See information from Toyota GB:

"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."

My 2020 model shows a sticker in the fuelling port E5 & E10 - is that a recent addin of information?

You can but the car will like E5 99 more and will also be more efficient.

Hi, we have been on this discussion many times and I have my thoughts well explained, here

 and some other posts you may find my experience shared. Best to try E5 99 and see if you can notice any difference yourself, then you can make a judgment rather to keep using E5 or E10., for me is E5 99 since September. 
Regards 👍

I haven't noticed any difference since using E10, fuel economy seems to be the same as far as I can tell.

The only oddity I had was after filling up for the first time, the engine was running more than usual and did not shut off as expected.  This seemed to go away after having been driven for a few miles.  Not sure if that was the computers making adjustments/measurements for the new fuel, but it has been fine ever since.
