Product Details

AMSOIL Engine Degreaser is a professional-strength aerosol formula that cuts through baked-on grease, oil residue, and road grime on engine surfaces with minimal effort. Spray it on, let it soak, and rinse it off with water.

Engine bays collect years of oil seepage, road film, and caked-on grime that regular cleaners struggle to touch. Leaking valve cover gaskets, weeping oil cooler lines, and differential pinion seal drips leave behind stubborn residue that traps heat and makes it harder to spot new leaks. A clean engine bay is not just cosmetic. It is a diagnostic tool.

REMOVES THE TOUGHEST GREASE, DIRT AND GRIME
The solvent-based formula in AMSOIL Engine Degreaser is designed to dissolve heavy petroleum-based deposits that water-based cleaners leave behind. Whether you are cleaning up a diesel engine caked in soot and oil film or prepping an engine block for a rebuild, the degreasing solvents break down grease on contact. Apply generously to a cool, dry engine, let it soak for 15 minutes, brush any heavy deposit areas, and rinse from the top down.

LEAVES NO RESIDUE
Some engine degreasers leave behind a film or oily residue that attracts new dirt almost immediately. AMSOIL Engine Degreaser rinses clean with water, leaving engine surfaces free of residue. This matters when you are cleaning around gasket surfaces, prepping components for inspection, or just trying to keep an engine bay looking presentable between services.

POWERFUL STREAM FOR TARGETED APPLICATION
The spray can delivers a strong, directed stream that lets you reach tight spots around intake manifolds, valve covers, accessory brackets, and other hard-to-access areas of the engine bay. You can concentrate product exactly where the buildup is worst rather than wasting it on areas that do not need attention.

SAFE ON ALL ENGINE COMPONENTS
The formula is safe for use on engine surfaces without damaging rubber hoses, plastic covers, or metal components. That said, cover any unsealed items sensitive to water before rinsing, including distributors, air filters, air intake systems, carburetors, electronic controls, and exposed electrical connections. Limit direct contact on under-hood wiring and electronic sensors. Wipe the product from exterior painted surfaces immediately to prevent spotting, and avoid use on asphalt or surfaces affected by organic solvents.

Application Notes
AMSOIL Engine Degreaser works on cars, trucks, SUVs, diesels, classic vehicles, and off-road equipment. It is effective for routine engine bay cleaning, leak diagnosis prep, and engine core cleaning before a rebuild. Do not use highly pressurized water when rinsing. After cleaning, start the engine and let it idle to ensure complete drying of all components. Repeat the process for especially heavy buildup.

AMSOIL Engine Degreaser is available in 15-ounce spray cans and is backed by the AMSOIL Limited Liability Warranty. Not available in Canada.

First, ensure the engine is off and cool. Cover any unsealed items sensitive to water, such as the distributor, air filter, air intake system, carburetor, electronic controls, and electrical components, and limit contact on under-hood wiring and electronic sensors. Shake the can well and apply generously to the dry engine, then allow it to soak for 15 minutes and brush heavy deposit areas. Rinse with water from the top down, remove coverings, and start the engine to idle for complete drying. Repeat as necessary.

AMSOIL Engine Degreaser is safe on all engine components, but you should wipe the product from exterior painted surfaces immediately if it contacts them. AMSOIL specifically warns against using Engine Degreaser on asphalt or other surfaces affected by organic solvents. Additionally, do not use highly pressurized water when rinsing the engine to avoid forcing water into sensitive electrical connections.
