Automotive Aftermarket Products

While best known for manufacturing high quality finished automotive and industrial lubricants, fluids, and greases, AOCUSA also manufactures similarly high quality automotive aftermarket products in two basic categories; (1) additives for use in the vehicle’s fuel system, including both Diesel and gasoline engines, and (2) cleaners and supplements for use with the various lubricants in the vehicle, including engine oil, transmission fluid, gear oil and power steering fluid. We can provide automotive aftermarket products to meet your needs. We market no brand of our own and won’t be competing with you on the shelves, so you can always be assured that your brand is our priority.

As it is critical to maintain fuel system cleanliness to maximize fuel economy and performance and minimize emissions, AOCUSA manufacturers fuel products containing state-of-the-art deposit control additives including polyetheramines (PEA) and polyisobutylenes (PIB) that effectively remove deposits from fuel injectors, intake valves and combustion chambers, returning fuel system to near new cleanliness and performance. For diesel engines, in addition to deposit control additives to maintain engine cleanliness, our diesel fuel products also contain components to address the deficiencies of current Diesel fuels, improving key performance parameters including Cetane number, lubricity and low temperature performance.

AOCUSA’s aftermarket lubricant products include those formulated to clean components in which the lubricant operates, especially when that lubricant is replaced as part of normal vehicle maintenance, and those formulated to enhance the performance of the lubricant itself. Our cleaning products contain detergents/dispersants as well as solvents to clean engine components of built-up sludge of other deposits while at the same time protecting these components and resulting in a cleaner environment for the new lubricant. We also provide lubricant supplements with components including viscosity modifiers, anti-wear and extreme pressure agents, rust and corrosion inhibitors and other components designed to improve the performance and extend the life of the lubricant itself.
