FYI. It's in store price for at least last 3-4 months. I bought few cans in September and October and paid the same price in-store

It's working. I used full can for 6 gal (not full tank) and it improved LTR by 4 on car with 140k

Most of these cleaner does barely anything .I tried couple of them, no MPG gains nor engine performance gains. just waste money for nothing.

NAPA has this at lower price $10.49, $10 off $40 if you sign up for NAPA mobile alert.
What was your car's mileage when you used it? Did you use the correct cleaner to gasoline ratio?
These things do work for your fuel system especially if you use anything lower than Top Tier gasoline. It helped eliminate my friend's car's rough idle, granted it was Techron and not this but still works about the same.

While priced cheaper at NAPA that code doesn't work on Royal Purple.

Would it be a good idea to use an additive like this after my car has sat for a few months while I was out of town?

Sea foam is great for the general cleaning of the fuel and PCV systems, depending on how you use it. However, it is not a catalytic converter cleaner. The RP Cat cleaner is, and a good one at that.


I have a 2010 Honda Accord that always has a check engine light on for the cat readings being out of spec. Every year I use 2 bottles of cat cleaner and reset the car's computer. It will keep the light off for a few days until right after it is inspected (twice, the light came back on on the way back from getting the inspection). I do believe that the RP Cat cleaner really helps clean out the fuel system and helps keep the check engine light off just long enough for my purposes.

It couldn't hurt, but you're better off putting some Sta-Bil in some gas and pouring it into the gas tank before you leave (letting it run long enough for it to get into the fuel lines), then putting a fuel-injector-friendly water removing fuel treatment in as soon as you get back.
