I saw Scotty Kilmer on utube recommend adding a half gallon of solvent to a half tank of gas and run it on the freeway for passing a smog test. I tried it but with less then a half tank and my mileage came back up over seven mpg.
I think that it cleaned the injectors.

sanderstheparro, the solvent is to clean off the surface so that the catalyst can cause the reaction that makes it hot. Whether it works or not is a different question.

Actually, a catalytic converter works efficiently when it is hot. That's why you need idle your car at 3000 rpms a minute or two before taking the smog test. It has nothing to do with solvent. scotty is an idiot.

"cleaning a catalytic converter is a lot cheaper than spending $1000 to replace it"

.....

Haven't owned a vehicle for less than 15 years and 130,000 or more and have not once had to clean a catalytic converter, replace one or have to clean the fuel injectors.

Perhaps just my good luck or then again perhaps its been the regular ongoing scheduled maintenance by authorized dealerships...

KansasGunman, cleaning a catalytic converter is a lot cheaper than spending $1000 to replace it, and a LOT cheaper than spending $30,000 on a new car.

Acetone, used properly won't hurt an engine and it will help reduce or eliminate combustion chamber deposits. I've been using it in conjunction with xylene for over 10 years. How much does it help gas mileage? It's hard to say but it's not that expensive so you're not risking much if you do experiment with it.

Recommended dosage is 2-4 ounces per 10 gallons. The Kilmer recommendation of a half gallon of acetone to a half tank of gas is massive overkill.

With regard to cleaning a catalytic converter, I'd go with a very slow, gradual cleaning by adding acetone to the fuel at the dosage I recommended. The results should be good but getting those results may take a couple of thousand miles.

If the tailpipe gives any real indication of engine cleanliness, then acetone certainly works because my tailpipe looks almost as clean as the day it came out of the factory.

I'm thinking that if some people didn't own a falling apart POS rolling junk in the first place or had a little something more than lint in their wallet they wouldn't try some hair brained ideas they watch on UTube and perhaps rely on qualified service.

I tried the lacquer thinner method and it didn't work. I did see a YouTube video that might work, however. I'm planning to try it. Drill a small hole in the exhaust just before the catalytic converter and spray carburetor cleaner into the hole. If your cat is simply covered with soot that should clean it off. As I've got soot coating the inside of my car's tailpipe, I'm guessing that should work.

In the video he sure measured out 1 gallon, by the guess and by god method.

Avoid “miracle” fuel additives and gadgets. The Federal Trade Commission has studied dozens of these products and concluded that none of them work. Some may cause engine damage or contribute to decreased fuel efficiency.

I would be concerned with an increase of solvent injected into the chambered cylinder walls/piston ring surfaces pre dissolving any lubrication properties in the porous structure of the cast surface cylinders.

Piston ring pressures are severe with combustion pressures going on constant and there is very little lubrication in those areas of high scraping speeds. The fitting tolerances there also are critical in nature for good sealing over many miles of use.

Its been said be carful how much the Ether Cold Start Spray is used to pre-charge an engine for a fire-up during very cold weather. The spray attacks lubrication, possibly causing a wash-down condition. on critical moving parts.

I've had decent results running a few ounces of acetone/xylene per tank, and I add some top oil (oil in the gas) to compensate for any lubricity issues. The concentrations are very low, however.

Kilmer advocates a gallon of lacquer thinner, BTW.

I've been using acetone/xylene for about 10 years on my Ranger without apparent problem. I believe that if the acetone dosage is proper, 2-4 ounces per 10 gallons, there won't be enough reduction in fuel lubricity to cause a problem but, that said, I have also used both FP Plus for Gas and Ethos FR to increase the fuel's lubricity beyond what's been lost with the acetone/xylene.

If the solvent that CIVX refers to is acetone then Kilmer is wrong to advocate using a half gallon. I'fe been using acetone for almost ten years in my Ranger but NEVER that much. The treat rate is 2-4oz per ten gallons.

For everyone following this thread : the OP sent me a private message and told me what he had used . my feeling it was risky at best, the product was made for another purpose. the use of this "solvent" can harden and crack plastic and rubber parts and damage electric fuel pumps. please do not use any product not made for cleaning automotive fuel systems.

Well, you need to be very careful what type of solvent you use because it will damage 02 sensors and gas lines.
