Oh yeah, it would really suck to go in for some sort of engine warranty repair and hear them say, you've been using 87 instead of 89, your warranty is void, have a nive day.

With that said I run 89 in the Hemi

RE: Which octane?
I use 91 or 93 with the Superchips, do you think that willcause any problems, using the higher then recommended octane? I don't think that it will since you are using a better quality fuel but I would like to hear some input... that and using the 87 with the superchips economy setting.

RE: Which octane?
Using the higher octane is fine(91+), just not worth it if you are running stock. If you have a tuner, great, but you won't harm the engine by running higher octane even without it. Higher octane means nothing more then the gasolines ability to compress before it ignites on it's own. That's why our manual states use 87, then if your eng knocks, up it to 89. The higher the octane the the more it can be compressed. It has no other properties. It exists for high-compression ratio cars light sports cars, modded hemis, etc. It contains nothing else that will do any good for your car like detergents or additives. As a matter of fact, it may be better to buy a "quality" 87 gas, then a "budget" 91 gas because of the quality of the gas. About 15 years ago in Cali it was proven that am/pm gas had more "crap" in it then any other brand, but that was why it was cheaper. Who knows now-a-days?
