Professional mechanics and do-it-yourselfers everywhere rely on this product every day. Sea Foam Motor Treatment dissolves and cleans fuel and oil residues and deposits, stabilizes fuel, controls moisture, and lubricates upper cylinders. Safe and effective when added to gasoline and diesel fuel and oil crankcases – Just pour it in! Berryman’s B-12 Quickly disperses moisture and dissolves gum, varnish, and other fuel residues from the entire fuel system, fuel tank, fuel lines, fuel injectors, valves, rings and pistons with H.E.S.T. Regular use ensures higher compression, fewer repairs, lower operating costs, and increased spark plug and injector life. Available in both consumer and commercial sizes. Catalytic converter and oxygen sensor-safe. HEST – “High Energy Solvent Technology,” a Berryman exclusive, incorporates the use of strong solvents, as opposed to weak carriers and diluents such as mineral spirits or kerosene. As a “tip of the cap” to our HEST technology, positive feedback regarding any of our products is affectionately referred to as a HESTimonial. Lucas Deep Clean is blended with an exclusive Lucas additive package and specific carrier fluid that contains no diesel fuel, kerosene or anything else that can be harmful or useless to an engine. It also reduces NOx emissions, eliminates the need for higher octane fuel and deep cleans the entire fuel system and combustion chamber. Filling up with a Techron fuel is always an upgrade, because our research and development never stops. At the Richmond Technology Center, our team of chemists and engineers test and retest Techron’s effectiveness in all kinds of engine and vehicle conditions–to bring you results that are far from standard. If you regularly use a high-quality gasoline such as Chevron, Texaco and Caltex, you probably don’t need Techron Concentrate Plus. However, should you occasionally fill up with lower quality gasoline, you may need Techron Concentrate Plus to help clean up deposits that can build up over time. In addition, if you have an engine that is sensitive to deposit formation, or if your vehicle is regularly used under severe conditions, you may also benefit from using Techron Concentrate Plus.
