Hey guys I'm new to the forum and wanted to ask a couple questions about this method of adding Lacquer thinner to my gas tank to clean my so called clogged catalytic converters. First off, I have a 2006 F150 5.4 with 90k miles on it and my engine light is on. When I took it to autozone, they said it was just a clogged catalytic converter. Well to be sure, I took it to another autozone, and they said it was an oxygen sensor. Has anybody ever tried this? I run a lot of ethanol in my truck. My instincts tell me that the catalytic converters are probably clogged because when I mash on the gas it doesn't accelerate as fast as it should being a V8. Can someone please help me?

 

Lacquer thinner in the fuel might possibly damage some non-metal items, I don't know. There probably is something made for vehicles that would be better. For the future, your best bet is to use a fuel stabilizer made for ethanol fuels all the time - with every fill-up. I use Sta-Bil super concentrate for ethanol fuels (blue) in everything I have that uses gasoline. I've been doing this for about five years and have had no trouble with any vehicle fuel or exhaust systems yet. It definitely keeps the cat converters 'sweet' like a new car.

 

I second the concern about damage to fuel system components.

 

Clogged converter may mean that the material inside has actually melted and is now a solid piece; not gonna clean that. Also, before doing anything, I'd have a more certain diagnosis done. These trucks have a habit of killing converters, often due to failing fuel injectors that stick open and pour raw fuel which eventually ends up running through the cats. Spend the money to have a reputable mechanic find the ROOT cause of the fault.

 

He also wouldn't be able to drive it.

No offense, but I'm pretty sure there's nothing in the substrate material used in catalytic converters that can melt and create a solid piece.

Thanks guys, ill have it looked at this week. I have a really good mechanic in mind!

 

Misspoke. Not a complete blockage of the exhaust, but instead of a honeycomb shape, it becomes a solid piece and [I]restricts[I] the exhaust flow, not necessarily seals it. The raw fuel hitting the hot ceramic ignites, and the ceramic melts as a result.

 

I’m not sure of everyone’s interpretation of what a "solid piece" is, but to me this looks solid. This was from my 2004 f150 supercew lariat 4x4.<O</O
