Lacquer Thinner in Fuel

Hey there, just wondering if any of you have heard of Lacquer thinner in your fuel to clean the catalytic converter. I saw it on Youtube so it must be valid .

My Limp mode went on and I thought it was a clogged cat. I reset it by taking the battery off, which set off an old alarm that I had to remove (another thread).

Anyway, is running good now so cat must be good? I suspect it was a loose OIL cap, almost ready to fall out.

But, he has 220k miles, 2005, so I figured it would help.
Thoughts?

 

NO on adding that stuff to your gas.

 

Loose oil cap wouldn't cause limp mode that I know of. I would be leery of adding the lacquer thinner to my fuel, but there are numerous references to it being effective. There are also numerous off the shelf chemicals designed for this. What codes were being thrown when the truck went into limp mode? Those codes will point you towards the right solutions. The SAIS is the most common reason discussed on here.

 

I've heard of using kerosene in engine oil to reduce varnish, but never seen legit evidence adding lacquer thinner in gasoline will clean your cats.

On a quick internet search using the big G, I found lots of less-than-reputable sites out there making claims it works. But they all read like my conspiracy-loving tnfoil-hat-wearing uncle in south TX wrote them.

 

Unless you fill your tank with lacquer, I wouldn't use it.

 

We all know that if something is cheap and ACTUALLY WORKS it will be bought out and removed from the market to protect profits - just like those 100 mpg carburetors from the 1960's (or was it 70's?).

 

Dale Gribble finds that reference to be offensive. When they really are out to get you, is it still paranoia?

 

I know some guys who attend Paranoid's Anonymous...but they won't tell me where they meet!

 

Most common issue that we would see that destroys a catalytic converter is running a higher octane fuel than is recommended. Trying to find this big article I had from a previous life in order to dissuade people from running 93 in their four and six cylinder econoboxes with the low, low compression ratio engines. Just couldn't get lots of people to stop throwing their money away and "burning most of that extra octane" in their exhaust/converters. Unless you're up there in the 10 to 1 compression area or higher, it's not doing you any favors to run the high octane fuel. I always assumed it got the converter to a higher temp than it could handle and would just destroy that honeycomb/matrix inside.

 

Doesn’t lacquer thinner attack the plastic gas tanks? Just another reason to avoid this “fix”...
