so no matter what your "designed" to run on. Dumping a litte super in it once in awhile will do ya some good. But you really don't need to run it all the time.
Sir, I honestly hope you don't believe what you just wrote, and I also hope that someone didn't just read that who doesn't know any better and believes it.

Why debate who is right or wrong? If you are curious just try a fill-up with 89 and see for yourself. I'm not even convinced that all 87 rated fuels are equal. Maybe some gas stations aren't really at 87 and some are over it. I have heard slight spark knock from some places and not others.

It has nothing to do with who is right or wrong, it has to do with what is right. If you want to throw your money away with higher octane gas because it makes you feel better go for it. Whatever gives you a warm fuzzy feeling go for it.

Bottom line is that lower octane gas is easier to ignite. In an engine with lower compression (like a Wrangler) it does no good to run higher octane gas. It gets tiring watching the dumb masses getting a cold air intake, throttle body spacer, k&n filter and running 93 octane who swear they feel a difference with their butt dyno.

Higher octane will lead to deposits on the valves as well. This is a lower compression, low tech engine. There is definitely no need for premium. Just run a little Seafoam through every now and then if it makes you feel better. Maybe clean your throttle body too. It needs it.

I'm a deer hunter. Every year $BAZILLIONS are spent in cover scents, and buck lures. Hunters sware by them. Most turn out to be nothing. You hunt the winds and where the bucks are. The smelly stuff doesn't mean a hoot to the deer.

I view the after-market additives the same way. I've never used them and had zero issues. Clean oil, new filter every time, change the fuel filter every so often and good fuel.

In my new '11 I'm burning Shell 87. In my Volvo 89 Shell. In my Supercharged Frontier 92 Shell. None either had or have fuel issues.

Its MHO......just saying a lot of money is spent by a lot of folks for stuff that makes them "feel like they have an edge". If it floats your boat buy it.

It amazes me how folks have science put right in front of them and refuse to believe it because they "just know" that their experience is different.
