Whats the difference between 91 red and 91 green at the gas station ?

i've been putting 91 red into my toyota since new but have noticed 91 green which is nearly 5 baht cheaper !

Will it run in my car and if so would it need setting up by toyota to run on it ?

thanks

91 Red is standard 91 benzene.

91 Green is E10 or locally called Gasohol91. 90% benzene blended with 10% ethanol

Depends on the model of your car. Almost all new models will run on Gas 91. Many older cars will have problems with Gas 91.

***Check with your manufacturer if you are not sure***

You'll get about 3% lower fuel economy on the green gasohol 91.

There hasn't been an engine built in the last 20 years that won't easily accept the 10% ethanol blend. If you have a really old Toyota, then maybe you could have an issue. But even then I wouldn't worry as the few parts which might give your engine a problem are cheap compared to the money you'll save in fuel.

There is no reason to use the red 91 octane fuel unless you like throwing money away.
