Fuel Grades, Bang For Your Buck

I was at my local gas station the other day filling up my 2000 3.8L Mustang, i was wondering the effects on upgrading the fuel going into your Mustang so i decided to research. I found that the higher number fuel grade you go the more octane the gas contains. More octane means hotter cleaner fuel consumption. Most production cars take regular 87 grade fuel, but some higher end cars run much cleaner on higher grade fuel.

So i switched my car to mid-grade 89 fuel. So far the effects are small but effective. My Mustang idles smoother, i have better throttle reaction, and my MPG has gone up 1 to 2 miles. Upgrading your fuel is like giving your Mustang its daily vitamins. I don't mind spending an extra 20 cents per gallon on fuel in order to sustain the performance on my Mustang and extend its life. I love the performance advantage i get from the upgrade also.
