## Description

Mr. Gasket Cataclean is a fuel and exhaust system cleaner that reduces carbon build-up and cleans your vehicle's catalytic converter, oxygen sensors, fuel injectors, and cylinder heads. Cataclean does not alter fuel composition and is safe for gasoline, diesel and hybrid engines. Testing at an independent emissions testing facility showed using Cataclean can lower your total hydrocarbon emissions by up to 50 percent (performance results are dependent on driver habits and vehicle condition). Use Cataclean to fix drivability issues such as power reduction, hesitation and hard starts, as a pre-treatment before an emissions test or to extend the life of your vehicle engine. Using Cataclean may help to avoid the replacement of costly oxygen sensors or your vehicle's catalytic converter. If you have to replace your catalytic converter, use Cataclean with the installation to extend its life. Cataclean is easy to use-simply pour in your fuel tank. Cataclean is 50 state legal and complies with VOC (including California) and OTC regulations, as well as Federal low sulphur content requirements for use in diesel motor vehicles and non-road engines. For optimum performance and protection, use Cataclean four times a year. Made in the USA.

Review: Save $1,400, when the yellow light comes on check engine had one of these lights out - The exhaust smelled funny kind of sulfurry, the dealer said that you had to replace all four oxygen sensors, 1400.00. So when the yellow light check engine comes on and drive it down to a quarter tank, toss in a cataclean, that was a year and a half ago, never saw yellow engine light again in the last 2 years, cleans the fuel system but the biggest thing is it cleans the O2 sensors and blast the catalytic converter , cleans it also, and that's the stinker, your two sensors before the engine light mileage was going down. We're not going as far on tankful, how to clean future catalytic converter cleaned clean your sensors pick up a couple miles per gallon, and yes you can tell the difference afterwards throttle responses is now. Works in any car.
Review: A Review-in-Progress: Some Immediate Benefits, Others to Wait and See . . - I haven't yet had any problems with the CEL or smog-test results with my 1995 orphaned Isuzu Trooper LS. But I have kept spreadsheets with dates, mileage, expenses and smog-test results for the vehicle since I bought it used in 2002. CA requires me to smog-test the car every two years for annual registration, and CA has some tough standards. Worse -- they made the emissions standards tougher across the board in 2008. I understand, though: There was a time during the late 1960s when the smog here was so bad, I couldn't see the time on the university bell-tower from the edge of campus, and I could taste the air. It had a flavor like sour milk. Reviewing the smog-test results over the lasts 20 years, I see that the HC and NOx results are edging up. Further, the HC result for December, 2021 was 59, and the maximum allowable was 60. Well, folks, I aim to stave off disaster. What would that disaster be, anyway? I budget $1,000 annually for repair and replacement on my Trooper. Sometimes I exceed budget; sometimes I'm under budget. But I invested more than the budgeted amount over the last 5 years with various restorations and parts replacements. If added to the average expense of my ownership for the last 20 years together with the monthly insurance premium, the vehicle has cost me about $180 per month over 20 years with the original purchase price also included in the average. Not bad for a luxury SUV, when the car-mortgage and insurance over the same time for three successive new-car replacements less trade-in or resale value might be two or three times as much. Replacing the catalytic converter, the heated-oxygen sensor and ancillary exhaust parts would cost at least $1,000, assuming I can find the part. If it can be avoided, I'll be better off. This Trooper, in the sunset of the petroleum age, will likely outlast me in my own sunset years. I followed the directions, realizing that a person would like to get the full value out of a $30 bottle of Cata-Clean. So I found a 15-mile stretch of highway, with gas-stations at either end, and drove two miles to the nearest station with a quarter-tank of gas and the Cata-Clean in the tank. I ran the vehicle down the highway, then added exactly 1 gallon of gas for safety, returned to the first gas station, added another gallon, repeated the trip a few times until finally filling the entire tank. The vehicle runs noticeably better. I will repeat this operation in three months and then again, until my smog-test in December 2023. I hope to see some good results. Platinum doesn't deteriorate. So if the product does as promised, the cat-converter should be totally renewed. If I spend $150 on the product and save the $1,000 expense, my year-long project will be totally successful. How does it work? The product creates carboxylic acid for the exhaust, which cleans the cat-converter. There is no damage to the metal parts, and of course the manufacturer recommends using it every three months or so. Cata-Clean is recommended by smog-test technicians, and my retired-mechanic cousin, who has read up on the product, also seems to think it will be effective.

## Questions & Answers

**Q: Do you have to drive consecutively the 15 miles out not?**
A: I absolutely would. I drive mine about 40 miles. 20ish twice. Gotta get it hot. If your car has lost power or won't drive that far, this won't work, that's a sign the element has completely plugged or broken up.

**Q: Why does the two pack cost more than buying two single cans separately .**
A: Not sure but I purchase the doubles to keep on hand.  The product does what it says.

**Q: Is there a refund policy if it doesn't work?**
A: just ask the company

**Q: How long should I wait before doing a second treatment?**
A: For best results do one treatment every 3 months.
