A peek at the MSDS shows: Acetone, Isopropanol, Xylene and Petroleum distillates. In other words, simply a run-of-the-mill "fuel system cleaner." It doesn't even contain the active ingredient PEA that gives products like Techron, GM top fuel system cleaner, Redline SI-1, BG44K and Gummout All In One with Regane their cleaning properties.
It certainly implies that it "cleans out" cat converters, and that cat converters can get plugged by carbon. This is completely false, and there is NO product that can "clean out" a bad cat converter. They cannot possibly get plugged by carbon as they are designed to operate at a very high temperature precisely so they can burn off deposits.
The other issue I have with this product besides the lack of PEA (which is virtually the only ingredient that actually does cleaning of fuel systems) is their test reports. They include some of the actual receipts with the test results, showing the CO CO2 and HC levels. There are a lot of those printed slips that show the RPMs too. You will notice that the RPMs read 0. This means they are reading the emissions with the engine off. Of course the readings will drop; the engine is OFF!!!!
I am not saying they are faking their tests but this company seems to specialize in misleading advertising (implying one can "clean out" a cat converter) and internet forum marketing.
There are other products of this ilk that will very temporarily clean deposits off sensors and combustion chamber deposits. Nothing can clean a cat converter but one can sometimes temporarily clean enough deposits upstream that they may pass emissions.
The problem with this is two-fold. One, it is only a temporary fix and if people drive for a week with a flashing CEL and never read their manual, they will toast their cat and no snake oil is going to help them.
The second problem I have with this is the attitude about only needing to pass emission tests for one day and not caring about poisoning our children the next day.
When it comes to oil products and gas additives, I immediately turn to - Bob is the Oil Guy
as the only forum I trust on those things.
If I needed a product to pass emissions, I would first change the oil, top up all fluids and run on the highway for a bit to get the cat to burn off deposits. Then I would use CRC Guaranteed to Pass because it does contain a certain amount of PEA.
