mixing 89 with 87.... any advantage?
So anyways, last week, i ran out of gas, and was down to like 2 packs. so i figured id better hit the rez, but i didnt have enuff gas to get there..so, on the way out (i realised this) i stopped at a gas station, that had no 87. they missed their shipment or something... so i put like 5 gallons of 89 in.
so i get out to the rez and put 12 gallons of 87 in.. now im no rocket scientist, but the butt dyno says the truck has slightly more get up and go power when the ac is on.... and it also appear im getting slightly better mileage (my needle aint moving as fast)
am i just going crazy or what?

This is assuming the tank had the correct octane in it.
My good bud used to deliver gas to stations with an 18 wheeler. He tells how station owners would say top the high test off with the reg or you don't get a check so.... Sure it's wrong but they would have to get caught.
Just like additives are added when they fill the 18 wheeler. Many small stations don't have the additives put so they can make a couple more pennies a gallon or at least be competitive prices with the corp. stations.
I remember when I pumped gas up the road years ago. We were $1.26 a gallon. The wholesaler was charging my boss $1.09 a gallon wholesale. The wholesaler was selling at retail from his station at 97 cents. Sure you could start crap about it but your delivers would show up on Sunday night when all the beach traffic was gone.
It's called the "real" world not a "reality show".

Unless you truck was designed to run on higher octane, you'll get no advantage. If you want to run a high octane, you have to advance timing. Yes, 93 octane packs more of a punch, but it is harder to combust, thus the reason for advancing the timing.
Victory is right about the quality of gas from "ma' & pop" gas stations, only refill if your in the middle of nowhere and running low. Not only is the quality of the fuel itself significantly less, but the storage tanks/filtering systems aren't the best.

Higher octane is a waste in a stock non tuned Ranger and actually can damage you emissions equipment as well as you giving more of your money to the "greedy oil companies" you complain about from time to time.
Its pretty easy to google and find out why, but here is the first site that came up on my google search.

^ It was a decent read, but this passage you need to read.
"WHAT IF I PREFER TO USE GASOLINE WITH HIGHER OCTANE RATINGS?
You can, but there are no real benefits, other than the gasoline manufacturers making more money off of you. When you use a fuel with a higher octane rating than your vehicle requires, you can send this unburned fuel into the emissions system. It can also collect in the catalytic converter. When you over stress any system, it can malfunction or not do what it was designed to do properly. In the early 90's, an early warning symptom was a rotten egg smell from the tailpipe. Easy fix, go back to using regular 87 octane gasoline. The rude odor usually disappears after several tanks of gasoline."
