- ✅ OPTIMISES THE EFFICIENCY OF THE CATALYTIC CONVERTER: Ensures the catalytic converter operates at peak performance by effectively removing carbon deposits and other contaminants that can accumulate over time. A clean catalytic converter improves overall engine efficiency, reducing harmful emissions and extending the lifespan of the vehicle’s exhaust system. Regular use helps maintain optimal exhaust flow, preventing blockages that could lead to costly repairs. Designed to restore lost performance in vehicles experiencing sluggish acceleration or increased fuel consumption. Enhancing the converter’s efficiency contributes to a cleaner, more environmentally friendly drive.
- ✅ ENSURES OPTIMAL WORKING OF THE LAMBDA (OXYGEN) SENSORS: Helps maintain the proper functioning of lambda sensors, which are crucial for adjusting the air-fuel mixture in petrol engines. A well-functioning oxygen sensor ensures efficient combustion, optimising engine performance while reducing excess fuel consumption. Prevents sensor contamination from soot and carbon deposits, allowing them to send accurate readings to the engine control unit. Keeping lambda sensors in top condition also helps maintain fuel efficiency and minimises the risk of increased emissions that could lead to MOT test failures.
- ✅ IMPROVES CLEANLINESS AND REDUCES EMISSIONS: Works by cleaning internal components of the exhaust system, including the catalytic converter and oxygen sensors, to reduce harmful emissions. Carbon buildup can cause excessive pollution, leading to higher emissions output and environmental impact. By removing deposits, the formula helps meet stricter emission regulations and supports a cleaner engine. Regular use prevents excessive carbon accumulation, ensuring compliance with emissions standards. Suitable for petrol and petrol hybrid engines, particularly beneficial for vehicles that frequently operate in city driving conditions where stop-and-go traffic increases carbon buildup.
- ✅ RESTORES ENGINE PERFORMANCE AND INCREASES FUEL ECONOMY: Helps regain lost power by improving the overall efficiency of the exhaust and fuel system. Carbon deposits and dirty sensors can lead to sluggish performance, poor acceleration, and increased fuel consumption. This treatment works by eliminating these inefficiencies, restoring optimal power output and fuel economy. By ensuring clean combustion and proper sensor operation, it supports a smoother drive with improved throttle response. Also helps extend the life of the engine and exhaust components, reducing the likelihood of expensive mechanical issues related to poor exhaust efficiency.

## Questions & Answers

**Q: It says add to 30 litres of fuel, how much is that ? Quarter or half a tank ?**
A: Depends on the size of your car. Mine was a 1.4 Ford Fiesta. Tank size is about 40 litres. Bigger car bigger tank. You should be able to google your tank size from the make and model of your car.

**Q: is this suitable for diesel engines**
A: No its for petrol engines but they do one specifically for diesel engines .

**Q: Should i put this in tank and next tank put injection cleaner in**
A: You can do, I wouldn’t worry too much tbh.
But let me tell you if you’re serious about using a catalytic converter cleaner, may I suggest “Duralube” as having tried and tested a few cleaners including the cleaner of topic, and my honest opinion there is no cat cleaner better and I’ve used wynns. Hope this helps

**Q: Hi, how soon before MOT is the best time to add to the fuel tank, a week before or a few days before, how many miles of driving for it to work**
A: If you only run the car for short distances most of the time. I was told by a garage a couple of days before an MOT, you put the cleaner into a quarter tank of petrol and take the car for a run. Drive it at 60mph in third gear for about 20 miles. It passed but, I've only done it the once so, I'm not sure if that was the answer.
