A TikTok creator says that for only $10, you can clean your car’s engine without taking it apart. He says it works so well, most mechanics don’t want you to know about it. Car repairs can be spendy, so like you, we were wondering if what the man suggests actually works. So, what’s the secret? According to creator Stonermaneuncut, it’s nothing more than Sea Foam Motor Treatment. He says it “cleans the injectors, restores horsepower,” and “quiets noisy filters.” It will also clean “unwanted deposits from your fuel lines and engines,” he adds. Stonermane goes on to say, simply pour it in your gas tank or oil crank case. Then, he says, drive for 50 miles, and you “can tell a big difference.” He used it on his own car and can testify that it works. “Works on all motors too!” a comment chimed in, supporting Stonermane’s claims. “It’s literally a tune up in a bottle! Even says it on the bottle,” the comment said. Meanwhile, another added, “I ran outside to tell my husband. He said ‘baby I use seafoam in all of our cars. I’m from the country.’ So much for my top secret hack.” Does Sea Foam Motor Treatment work? @stonermaneuncut #tiktokautocampaign #cartips ♬ original sound – STONERMANE UNCUT From our research, Stonermane’s claims are pretty accurate: the types of car repairs Stonermane and Sea Foam claim to address could indeed cost thousands of dollars if handled professionally, but it depends on the severity of the problem and your vehicle. But if an engine already has significant damage, Sea Foam won’t replace professional mechanical work, and the cost of repairs could indeed run into the thousands. However, the TikTok creator’s claims about Sea Foam Motor Treatment are largely supported by both manufacturer statements and user experiences. Sea Foam is formulated to clean fuel injectors, remove carbon and varnish deposits, and lubricate upper engine components. According to the official Sea Foam website, it works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas Sea Foam. Users have reported improvements such as smoother idling, increased horsepower, and enhanced throttle response. However, while Sea Foam can be effective in cleaning and maintaining engine components, it’s important to note that it may not resolve all engine issues. For instance, it may not effectively clean carbon buildup in intake valves on direct injection (DI) engines, a problem that often requires more intensive procedures like walnut blasting. Additionally, some users have reported that Sea Foam can dislodge significant amounts of sludge, which, if not properly filtered, could potentially clog fuel injectors. But if you’re a shade-tree mechanic, you might as well try it out — for just $10, you won’t have much to lose. Just remember: Sea Foam Motor Treatment can be a useful tool for maintaining engine performance and addressing minor issues related to fuel and oil residues. However, it’s not a cure-all and should be used as part of regular maintenance rather than a solution for major engine problems. Always follow the manufacturer’s instructions and consult with a professional mechanic if you’re unsure about its suitability for your vehicle.
