Very tight fit on 74mm Mobile 1 Filters
Color: Silver
It claims to fit "some" 74mm Mobil 1 filters. It's a fraction too small, but will work if you "force" the tool on the filter.

Works if you need help. Not a miracle in a bottle.
Size: 1 Count (Pack of 1)
It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

Worked like a charm.
Size: 1 Count (Pack of 1)
Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.
