Will Sea Foam lower hydrocarbons and help pass a smog test? [SOLVED]

I’m reaching out because I’m trying to pass a smog test in California and was wondering if you had any tips.  I have a 1999 Toyota Avalon (3.0 L V6) with just over 219,000 miles. It still drives great and is in good shape. I failed a smog test last week and am trying to figure out how to lower my hydrocarbons (PPM).

Got any recommendations?

Hi Caleb. We get A LOT of questions about how to pass a ‘smog’ test. Here’s what we typically recommend to help a gas engine produce less hydrocarbon emissions: With a low tank of fuel, add a couple cans of Sea Foam High Mileage and drive 20 or so miles. After driving and working the High ┬áMileage concentration through the fuel system, do at least one Sea Foam Spray treatment through the throttle body. If it were me, I’d do two complete Sea Foam Spray treatments in a sequence. When done, add fuel and drive a couple days to continue to burn off the hydrocarbon residues. That’s it.

Keep in mind that every car is different and has its own degree of combustion efficiency. Even so, what was just described is the best quick-fix approach to a cleaner burning engine we know. Hope you’re successful!
