"Plus, a car's engine may be more forgiving."
A modern car's computer should be able to adjust the fuel injection to handle a wide range of fuel qualities.
I had a sedan and accidentally put "premium" fuel in it instead of the 87. The computer recognized the difference and the check engine light came on, but the car ran fine. At the next fill I put 87 in and the light turned off. I wasn't expecting an "upgraded" gas to do that, but the owners manual did stipulate to only use 87.
"How much fuel you added and how much was already it the tank are the probable reasons it worked."
It was about 50/50. Granted, I have an E85 so the car is engineered to use crap fuel by design.
I wouldn't put old gas in my 95 Dakota. Because I drive it so seldom the gas ages in the tank on it's own. I use ethanol free and PRI-G just to be safe.
