I'm not an engineer either, but I might become one if I'm not careful!

Way back in high school mechanics, we had a short lecture on gasoline &
the stuff they put in it.
Any car is less likely to know at high altitudes once it's been there for
a while. High-altitude gas is different than sea-level gas (I think!!);
similarly, cold-weather gas is different than summer gas.
So if you fill your tank in colorado, then drive to the coast, your car
may not run so well when it gets there. Ditto for the reverse.
This is just a theory based on somewhat hazy memories of high school.
