Seemed to work as well as or better than some more expensive catalytic converter cleaners. I put it in while at 1/3 tank and my Check Engine light went out almost immediately once I started driving. My Tundra has almost 230,000 miles and still runs great but was getting a little harder to start after I switched from full synthetic oil to conventional. I’ll never do that again and immediately switched back but the damage was done. Check engine light came on and I had to crank longer to get it started. Adding this Liquid Moly fixed both issues temporarily. I have to wonder if this was used regularly, say every 3 months, if it would clean the catalytic converter more permanently?

Actually works on BMW!

I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
