I'm bit of YouTube mechanic came across a Scotty Gilmore video on YouTube yesterday of adding a gallon of lacquer thinners too half a tank of fuel and driving highway speeds for like 100kms to clean out cats might try that ..I got a scan tool I should check if I can get diagnostics for cats but I doubt a 2002 that advance

 

I really have my doubts that will work. If you look at the composition of petrol they use Toluene (thinners) to raise the Octane. I add 2L to 18L of 98 to raise the Octane level but it does burn dirty. You really need to do some testing to see where the problem lies.

 

I have personally talked to him in person …. DONT run lacquer thinner with hopes of cleaning your CAT. I know the YouTube among most of his. He’s an interesting guy.
He’s like the towns doctor … once they get there MD credentials many never go back to school to learn the updated info.

From 1995 to present vehicle use OBDII or CANbus that means you scan tool should work on your Mazda

 

Yeah tried the scanner on it no diagnostics for cat temps only 02 sensors not a bad scan tool aot won't do such an early model so I figure the car just doesn't do temps for cats IL have to get one of those digital thermo things Cheers for advice

 

Australia didn't go OBD2 till 2006 but that Mazda is full on OBD2. The thing with thinners yes it's a great solvent as a liquid but probably after it's burnt would be useless as a solvent. Good old Scotty. I think he's given up the Utube clips and enjoying retirement. .

 

I use Xylene for decades even 100% and it burns clean. If it were not so expensive I would run it all the time instead of gas.
It will not clean a CAT , it does raise the EGTs slightly. It does not support the formation of carbon deposits in fact it will help remove high carbon deposits.
If you Calibrator your ECU it will support higher power levels . If you use it 50/50along with LPG to a gas engine it will support the total engine power output if ECU calibrated for that combo. Especially on a Supercharged engine .

 

I'll dispute that one.

What happens when toluene is burned?
The decomposition of o-QM to benzene + CO reveals a potentially important new pathway for the conversion of toluene to benzene during combustion. A number of the important products of toluene combustion proposed in this study are known to be precursors of polyaromatic hydrocarbons that are involved in soot formation.

 

You can dispute it all you want I have posted information on using it I buy it buy Xylene the case and have used it since the 1980's. I have also created Files to upload in about a dozen ECU that my customers use in various countries to use toluene instead of the bottle octane booster . And the use of it has been written up in so many Hot Rod and Muscle car magazines for likely the same time period as I have been using it.
And had you actual experience regarding emission testing a vehcle you would realize that for some cars that are on the edge of passing or did not pass by slightly going over the emission standards a qt or 2 of toluene and 20 minute drive at about 50 mph can pass them will withing the emission range and it completely legal in all 50 states where a emission test is required.

So [please use experienced information and not the chemical reaction breakdown which does not account for the actual emission measurements HC and CO at the tail pipe nor did you post anything regarding the higher DYNO tested results when using even small amounts of it. Oh and lastly try doing a power and pull spark plug reading and post what you found.

Just one tail pipe information reading using an EGA ( Exhaust Gas Analyzer) or an emission test you had to perform or stand by and assisted in to support your research please. I am not even asking for documentation sir!

I have noticed a pattern with your responses if you have not done a service or experienced something auto related yourself you often post information based on what you find. What kind of an auto mechanic or auto tech were you exactly? And it is also funny that you stated yourself a suggestion to use Toluene?? hmmm??

 

My comments come from many years of experience and knowledge. Yours? Thats another story.

 

Burns clean?
