Is this stuff safe for a 2011 Dodge Challenger?

The manufacturer claim is "safe for gasoline cars" so should be safe for 2011 Dodge Challenger. A buildup on the catalytic converter, could be a result of gas not burning completely, check spark plugs and coil.

Is this safe to use in a 2015 Mercedes Benz Ml350 (w166)?

I have a Kia Soul 2.0 2012. According to the manufacturer this is safe for gasoline engines.

So the year and make doesn't matter for this product right?

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.
