I went and picked up some octane booster/fuel cleaner kit. I ran it w/ regular gas I noticed a slight difference in performance, it didn't hesitate throughout the gears, and got up to 60 slightly a bit quicker.

But my question is could this be harmful to my engine If I kept using it? my engine has 96,000 miles on it, and was only going to plan to use after every oil change.

So should I continue to use it or not?

I'm glad a few people understand how octane really affects an engine. For everyone else here is a little info. I used to think that the higher the octane the better. Then I did some research. On a normally aspirated engine higher octane fuel can actually hinder the engines performance. Octane is a measure of how fast the fuel will combust. 87 octane fuel will combust faster than 92 octane fuel. Fuel companies put additives in there fuel to help keep engines clean. The more additives in the fuel, the higher the ocatane and the slower it will combust. So in a normally aspirated engine, using higher octane fuel is not only limiting your performance but also dinging you in the pocket a little.

The only time higher octane fuel is better is if you are running a turbo and your timing on your engine has been retarded. When these conditions are present, the higher octane (which burns slower) allows more air to enter the cylinders before combustion occurs.

I hope this helps a little bit. I am sure a lot of you are surprised to hear this, but do some research and you will see that I am right.
