You should not need 91 unless you have a "hot" setup with a programmer or a Super Charger. </div></BLOCKQUOTE>Ken, I have a question about this actually. What is programmer doing to get more power? I'm guessing it advances the timing and changes the air/fuel ratio, but not really sure.

I've used mine on 91 Octane Performance running 87 gas and didn't have pre-ignition even under hard acceleration. I still run the 87 Octane Performance program though as it does the job just fine for me. </div></BLOCKQUOTE>Timing, air/fuel and shift points are the main ones. Sometimes people won't get pre-ignition until the upper RPM range of each gear. Or a pinging at the shift. It sounds as if most programmers just give you choices. When I say "hot setup" I mean actually going into the programming and tweaking each point individually. I don't know if you can do that with "everyday" programmers. I think this is what Taz is looking into with the Nelson.

Thank you all for your wisdom. I haven't been having any problems relating to this, but rather, had been told that doing this is good preventative maintainance. I will check with Mike Sabaresse when I get my next service. I'll share his opinion with you then. Again, thanks! You guys are the best.

Gary, do we have any dates for Moab and the EC/WC-FO?

just speaking from experience. I've had to have the injectors replaced in my 4-runner as a direct result of using a fuel injector cleaner purchased from a national chain.

The engine has recently been rebuilt along with the injectors being replaced by someone I trust. The truck was running perfectly. I went on a cross country trip and got a couple tanks of what I will call bad gas. The trucks performance suffered instantly after each fill-up and specifically after the last fill up in po-dunk no-where . Being 3000+ miles from home I went to an auto parts store purchased several bottles of fuel injector cleaner and with each proceeding fill up of 20+ gallons I would dump a bottle in as per the instructions on the back of the bottle. When I got back home and took the truck back to "a mechanic" I trust I was informed that the injectors needed to be replaced.

I do agree with you that mechanics by there very nature are in business and that business is to make money. This particular mechanic who is a family friend has gone out of his way to point me away from useless repairs or repairs he felt were un-necessary. I usually get a couple of opinions when I experience trouble and my friends is usually the last one I seek and more times than not I find that I have been lied to by other mechanics just looking to make a quick buck.

Sound advice is a matter of perception. I am merely relaying a past experience I experienced choose to ignore it if you like. Perhaps you have had a positive experience with fuel injector cleaners and the product works for you. I couldn't be happier for you.
