I recently read a looooong thread (posted at ClassicalPontiac.com) about DynoTab, a product in pill form that you drop in your gas tank for increased compression, higher octane, and elimintated engine ping. Sounds kinda like any "octane booster" product, which we all know are useless for the most part. But this stuff is actually supposed to work:

Has any heard of (or used) this product, with any mentionable results? I would be very interested in try it in my '69 Executive, and maybe even the Aurora!

I dont know, seems a little fishy. I know there is gas additive out there that can easily raise your octane level to over 100, but it costs money, and could be dangerous. Sort of like a race prep mix.

Yeah that is Toulene, or Xylene... lots of guys at ClassicalPontiac.com have made their own mixtures, since our classics were built for 100 octane gas back in the 60'*. It is generally successful, but is potentially hazardous, messy, and overall a PITA.

I wouldnt want to put anything in my gas tank that wasnt in liquid form.
I'm skeptical about it. Modern engines have all sorts of sensors to make sure that gas is being burned off therefore making this pill obsolete.
I couldnt find what exactly the pill is made of. :?

I don't think that much of the additive would even make it to the motor....Something tells me the fuel filter will catch most of it...and I highly doubt that it'll do anything to the fuel.
