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 (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. Use four times a year to help maintain proper engine operation and catalytic converter efficiency. One application may not clean an already unhealthy catalytic converter, but the recommended four times per year usage can restore a dirty catalytic converter, maintain a healthy catalytic converter and support a well-running engine.

A buildup on the catalytic converter, could be a result of gas not burning completely, check spark plugs and coil. **Q: Is this safe to use in a 2015 Mercedes Benz Ml350 (w166)?** A: I have a Kia Soul 2.0 2012. According to the manufacturer this is safe for gasoline engines. **Q: So the year and make doesn't matter for this product right?** A: Don’t know about the year thing but I have a 2018 Ram 1500 4X4 Eco Diesel and a code tester. Check engine light came, it was a sensor in the catalytic converter, dealers like to say you need a new catalytic converter, YouTube and it said use this, so I did what it said, put it in my truck at less than a 1/4 tank drove for about 45 minutes, then filled it up. After starting the engine a couple times the light went off. And all was good, saved a lot of dealer charges. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth it *by M***M on 19 August 2025* Great product ### ⭐⭐⭐⭐ 1 bottle : Done the job for short period *by T***D on 1 May 2026* Car : Ford Explorer 2013 at 280k+ km on odometer have P0420 and P0430.
