Sea Foam
<h3>About Sea Foam: Over 80 Years of Engine Care</h3><p><strong>Sea Foam</strong> has one of the most storied origin stories in the automotive aftermarket world. The brand's history dates back to the 1930s, when Fred Fandrei — a salesman in the petroleum industry — grew frustrated spending more time repairing his outboard motor than actually fishing. That frustration led him to experiment with petroleum-based formulations that could prevent fuel from breaking down and gumming up engines. By the early 1940s, the product was trademarked, and Sea Foam Sales Company was officially born. Early endorsements from Evinrude Outboard Motor and Martin Motors helped cement the brand's credibility, and it has been trusted by professional mechanics and DIY enthusiasts alike ever since.</p><h3>What Makes Sea Foam Different</h3><p>Unlike many chemical treatments on the market, Sea Foam products are made from <strong>100% petroleum-based cleaning and lubricating ingredients</strong> — meaning they're engineered to work safely within the chemistry of fuel and oil systems without introducing harsh solvents or incompatible compounds. This approach has earned Sea Foam a reputation for being both effective and gentle, making its products appropriate for a wide range of gas and diesel engines, from daily drivers and high-mileage trucks to motorcycles, outboards, lawn equipment, snowmobiles, and chainsaws.</p><p>At the heart of the Sea Foam lineup is its flagship <a href="/7748-sea-foam-fuel-additive-12140">fuel additive</a>, Sea Foam Motor Treatment. When added to a gas tank, it cleans injectors and carburetor passageways, stabilizes fuel for up to two years, controls moisture, and lubricates upper cylinders. When poured into the crankcase, it works as a powerful <a href="/7748-sea-foam-oil-additives-200733">oil additive</a>, liquefying harmful residues and deposits that restrict oil flow and cause problems like rough idle, oil burning, and loss of power.</p><h3>A Complete Engine Care System</h3><p>Sea Foam's product range goes well beyond its iconic Motor Treatment bottle. The Sea Foam Spray line serves as a direct <a href="/7748-sea-foam-engine-tune-up-carburetor-choke-carbon-cleaners-201932">engine tune-up and carbon cleaner</a>, working through a gas engine's upper air intake to dissolve stubborn carbon deposits from intake runners, intake valves, and combustion chamber areas — reaching places that tank additives simply cannot. A complementary <a href="/7748-sea-foam-engine-tune-up-carburetor-choke-carbon-cleaners-200375">carburetor and choke cleaner</a> formula keeps fuel delivery components free of varnish and gum buildup that can cause hard starting and hesitation.</p><p>For vehicles experiencing rough shifting, erratic steering response, or sluggish hydraulic systems, Sea Foam's Trans Tune product is a trusted solution. It's formulated to dissolve gum, varnish, and moisture from <a href="/7748-sea-foam-power-steering-fluid-11395">power steering fluid</a> systems, automatic transmissions, and hydraulic circuits, helping restore smooth, responsive operation without a full fluid flush.</p><h3>Trusted by Mechanics, Built for Everyone</h3><p>For more than 80 years, Sea Foam has built a loyal following among professional mechanics, weekend wrenchers, outdoor equipment owners, and boating enthusiasts. The brand's philosophy — safe, proven ingredients in simple pour-in applications — means that anyone can use these products with confidence, regardless of mechanical experience. Whether you're prepping a vehicle for winter storage, troubleshooting a rough idle, or performing routine fuel system maintenance, Sea Foam offers a straightforward solution backed by decades of real-world results.</p>
