    Salut Erwin! Ce sont des resultats pour des tanks complets? Conditions meteorologiques identiques?

    Well if you want to burn non-ethanol fuel and get around 10% better fuel economy, then run 91 octane. That is what I do on all my gasoline powered vehicles, motorcycles and lawn equipment.
    Ethanol is hard on all of it. IMO and my mechanics. My mechanic builds hot rod, race engines, etc, etc.

    ... the engine runs fine on 87, I found if you put straight premium in it the fuel economy actually suffers a little... the engine from the factory is tuned to run on regular, and that's what it likes. I tried a mixture about 50/50 and the economy improved somewhat.. seemingly to normal... but I would never use premium on a regular basis.. no need

    All vehicles that are gas will run any grade. They just retard the timing. Its no big deal. Now the EPA admitted that ethanol ruins emissions equipment. Old news: https://www.asphaltandrubber.com/new...engine-damage/

    If the car isn't tuned... Regular is the one to pump!

    .... it's my understanding that only a few stations sell gas that does not have ethanol, which I do believe degrades performance a bit. Shell 'V Power, 91 octane.. the $$ premium stuff supposedly has no ethanol.

    I live near Manzanillo and I understand Pemex does not pollute the gas they sell here with ethanol, Mexicans like to eat the corn they grow... usually in the form of tortillas. Their regular gas known as magna verde works just fine in my new 2021 Micra automatic, only US $12,000 and badged as a Nissan 'March Sense" here.. standards are far more common here, and about US $1000 cheaper.
