If you mix low octane gas (say, 87) with higher octane (say, 91 or 93), do you get the average, or something else ?
I ask because I can get 87 through my employer, but my car doesn't run well on it under load. If I mix it with 91 or better at personal expense there is a definite improvement.
I have heard that gas stations only really have Regular and Super in their storage tanks, and they are mixed at the pump for the Mid-Grades. I don't know if that's true, but if it is I'd like to know how to optimize it.
