Not that my truck is much faster with the higher octane. It runs smoother and it doesn't sound like it's going to explode as much at high rpm's. It's quiter and smoother.
Check this out...

Use 89, sometimes throw 93 in. Use only Sunoco, Amoco, or HESS.

I just read my manual and it says to put 87. I have been putting 93 since I got it. I though it would be better for it. The manual says that if you put a high octane the engine would feel underpowered.

Fine I guess but it seems to be a little sluggish. I'm going to try SeaFoam. I'm putting it through the Vacuum Line and gas tank. And before my next oil change I will put it in the engine and the put fresh Royal Purple in it!

6.1L Hemi

93 Octane

BP only as certain other brands (like Shell) make it have a very strong odor from the exhaust under heavy throttle.
