ethanol in gas bad for our cars?

4 oz for every 10 gallons fuel. It's less pricey if you buy the gallon jug. It's like giving Goldie a treat, he seems to like it and I figure it can't hurt.

Try running a tank without it. Get it fully warmed up on a hot afternoon with the ambient temp 90 or better, and see what it does.

Just a little experiment.
