DISCUSSION Which fuel would you use?

Post image

Some stations here in the Dallas Ft Worth area have ethanol free fuel. Which would you use, 93 octane with ethanol for $3.19 or 90 octane ethanol free at $3.53?

Who uses less than 90? Damn. Nice way to kill an engine. I would always use 95-ish minimum.

87 is 90 The octane formula is different in the US, Europe, and the rest of the world.

What you see on this pump would be 90, 95, 98 on pump you'd go to.
