RXP Generation II
One product you can get in one of several thousand autozone stores around the country if you're in the states is: RXP Gas Kicker. It comes in a little red or yellow bottle...2 oz each. Maybe about $6/bottle or something. It was always the #1 off the shelf product that actually gave significant gas mileage gains but was marketed for emissions.
That is the original RXP formula and has been sold in stores nationally for many years. People who couldn't pass emissions would just put that little bottle in with a tank of gas, drive around for a bit, then pass emissions with flying colors...guaranteed too.
For best results, you wan to go through at least 2-3 full tanks of gas with the additive and during this time...the first tank and a half, the emissions will gradually increase since it goes through a "decarbonization" period.
% Carbon
Monoxide Complete de-carbonization of the engine takes time. Each engine could respond differently. Allow enough time for RxP to do its job.

Within First Few Minutes
After Initial De-Carbonization
Then the emission start going down. If you pull your plugs out before and after, you'll be shocked at how clean the plugs are!!
It is just slightly different than RXP Generation II. Gas Kicker is better at dropping emissions and Generation II is a bit better for higher mileage. I think the main difference is that Generation II has x ppm of biodiesel in it. I can't recall off hand.
Anyway, I've seen the 5 gas analyzer tests up close with this product over and over and it works every time...on gas, diesel, kerosine, etc... I add the Generation II to my oil furnace tank. My friend actually developed the first protocols ever that will allow the Chicago Climate Exchange to track trucking companies for emission reduction and allow them to get carbon credits. With the 5 gas analyzer tests, it can show if a trucking company is in compliance and can prove if they are actually using the product if they agreed to use it as their means to reduce emissions. By the way, carbon credits is only one emission credit is given for and this is the one people are learning about...there are credits for all the other emissions like carbon monoxide credits, nox credits, etc...
On untuned high emission diesel rigs, adding the RXP Generation II alone dropped the exhaust temp up to
100 degrees! It didn't give the HP increase like the Firestorm plug claims but when you see temp drops like that...an overheating diesel, you know it is dropping nox through the floor.
That product started as FlameX in the welding industry MANY YEARS AGO and isn't just some newly developed product to capitalize on the rising gas prices. When added to the fuel mix has it mixed in, the flame almost resembles an implosion with very little wasted radiant heat burning outwards so the flame is extremely concentrated to a fine point. Its very interesting!
I don't have experience with welding but the famous example is:
"Welding technician performing a backwash "gouge" cut using FXD."
By controlling the radiance of the flame the metal is left cold enough for the technician to immediately place his hand over the gouged area. This demonstrates the unique burning characteristics of FXD.
The hand can be placed on the metal by it immediately because all the heat was concentrated where you wanted it instead of much being wasted radiating out heating up everything else.
Same effect in engine...the fuel mixture contains more of the heat so less is radiated out to the metal...I know it sounds weird, but that is what actually happens and the engine temperature drops while giving more power.
The formula isn't 100% identical to FlameX..it is tweaked a bit specific for engines.
In a 1996 Saturn sedan 5 speed, on a trip to Seattle a couple years ago...when adding 1/2 oz of RXP Generation II per 10 gallons of gas, I got 43mpg on the highway...(without an efie) and no other modifications on the car except some magnets on the fuel line.
Last June, I drove a 1995 Nissan Altima 5 speed to Vegas and back (from Eastern Washington) and using the same amount (1/2 ounce per 10 gallons), I also got 43mpg average on several tanks. The other tanks were averaging 38-39mpg.
