2014 Toyota Highlander: Can It Run on Ethanol?
May 1, 2014
Remember Ethanol? It was the hot alternative fuel there for a while not too long ago. GM even put yellow gas caps on all E85 capable vehicles to encourage people to uh..."go yellow."
Those drums aren't beating very hard anymore for various reasons, but there are still plenty of stations that serve up gasoline mixed with varying levels of ethanol. And there are still plenty of vehicles that are certified to burn both, but our Highlander isn't one of them.
As you can see, Toyota only recommends gas mixed with up to 15% Ethanol. It'll probably run on higher dosages, but doing so will likely void the warranty. Probably not worth whatever minor price difference there might be between ethanol blends and pure gas.
