Correct. You don't get any better mileage when you use a higher octane fuel than the truck requires.
And, it take more refining to make a higher octane fuel, and that means it requires more oil to make a gallon of higher octane fuel than a lower octane fuel. So you are wasting oil if you are using a higher than need octane fuel.

This is correct but incorrect. Additives can put in gasoline to increase octane ratings. Some work better then others and some are actually more harmful to the engine or environment. Some have been banned by the federal government. Lead was a perfect example of a additive that worked good but was bad for the environment.
To answer Frank's question: Started with low octane regular, if your engine knocks go to the next grade. Try different brand gasolines. Some vehicles seemed to run better with different chemical additives to help your engine run cleaner and more efficient.
