It does change. It has to do with evaporative emissions, you have less evaporation in the fall and winter when it is cold. But in colder climates IE Montana, you need something that will burn quicker more like in summertime, so it has more aerosal characteristics but is more potent. If that makes sense. While summer they switch to a less evaporative fuel that takes more to burn, which the extra heat of summer will take care of.

I removed the headers and use stock manifold gaskets. To my amazment the headers were white, Clean from running premium fuel.
That means that all the fuel was being burnt giving more bang for your buck if you will.
The suit from the manifolds was a sign of unburnt fuel in the exhaust.
If you have a 20 gallon tank and premium is .20 more than regular it will cost only $4 more per fill up. (if empty)
In my ranger i get 300 a tank on 87. When I run 93 I get 350. At 15 miles a gal on 87 I would have to buy another 3.4 gal. to get the same miles.
If gas is $3/gal, then to get the same miles it would cost an extra $10.
Had I bought the 93 I would have only spent an extra $4 at the fill up. Saving you $6 each fill up. If you fill up once a week you will have saved $312 a year. And your truck will be running better/cleaner.
Also, around here we have good gas (shell,BP,Marathon) and cheap gas (wesco,Speedway,wal-mart) and that makes a HUGE difference.
I had ran the wesco gas and was getting 250 miles a tank, switch to shell and got 350. And that is NO BS.

Um, it doesn't matter what you run for fuel, you will get soot, every exhaust gets soot, that is part of the emissions, and crap the government is trying to reduce. Running headers will change the way an engine runs and pushes exhaust gases out. You also didn't run your headers as long as the stock manifolds and exhaust manifolds are not as smooth as headers, so they will collect more crap. But truth be told, yes you apparently saw a difference. I can't explain that, but from everything I have researched and experienced myself, you in no way need to buy premium. Maybe I'll try this myself and see what it results in. But I find it a little hard to believe this. Also by switching to higher octane fuel at the same time as you switched the headers really didn't give you the chance to experience regular fuel mpg on that set up. Which will scew your results.
