Regular gas vs. Ethanol-free gas

Post by JonCleveland » Thu Aug 25, 2016 9:43 pm

Has anyone started using ethanol-free gas in the car? Does it work better than 10% ethanol or is it just all hype?

Ethanol-free gas should give you a tiny bit better MPG.
2000 Ford Taurus SEL (excellent car, sold to a friend)
1992 Mercury Sable GS (good car except for the tranny, sold)

About three months ago, we switched from brand-name 93 octane to 87 octane octane ethanol free in all of our vehicles that are specified by the manufacturer to use 87 octane gasoline. The gas mileage is very slightly better (1 mpg?) but the main advantage is the engines seem to be smoother at idle and the throttle bodies are not requiring cleaning as often to remove the "gum". Possibly a side benefit will be the reduced deterioration in the lines / components that ethanol erodes. Hop this helps.
