Will adding Sea Foam to my gas harm my 2021 Camry engine or sensors? [SOLVED]

Thanks for the question!

No, Sea Foam will not harm the engine or sensors in your 2021 Toyota Camry. Just follow the directions on the can.

Sea Foam is made from a mix of petroleum-based cleaning and lubricating ingredients. When added to fuel, it works to clean fuel residues and deposits from the fuel system.

Here’s what I’d do to get the most cleaning power out of a can:

• Wait until the tank is low (about 1/4 tank or less)
• Add a full 16 oz can of Sea Foam
• Drive at least 10–20 miles before refueling

The high concentration works much better and faster than adding it to a full tank.

Many people use Sea Foam as preventative maintenance to keep the fuel system clean and help prevent deposits from building up over time.

Hope that helps and let me know if you have any other questions!
