Product Description
KATMOTO Engine Flush Oil is a fast-acting internal engine cleaner added to the used oil shortly before an oil change. Its concentrated detergent-dispersant system dissolves and suspends sludge, varnish and deposits from oil galleries, rings and the valvetrain, which are then removed with the old oil at drain, restoring engine cleanliness and oil-flow efficiency for the fresh oil fill.
Key Performance Features
| Dissolves sludge & varnish
powerful detergents loosen and suspend internal deposits and sludge. |
Frees sticking rings
helps free stuck piston rings and clean the valvetrain. |
| Restores oil flow
cleans oil galleries and the pickup for better fresh-oil circulation. |
Fast-acting
works in 10–15 minutes of idling before draining the old oil. |
| Safe for seals
compatible with engine seals and gaskets at recommended use. |
Gasoline & diesel
suitable for gasoline and light-duty diesel engines. |
Applications & Performance Level
| Applications | Gasoline and light-duty diesel engines, added to the used crankcase oil and idled for 10–15 minutes immediately before draining the old oil and refilling with fresh oil. |
| Specification | Pre-oil-change flush — internal engine cleaning before an oil change. Detergent-dispersant — dissolves and suspends sludge, varnish and deposits. Seal-safe — compatible with engine seals at recommended dosage. Gasoline & diesel use — suitable for gasoline and light-duty diesel engines. Improves new-oil performance — restores cleanliness for the fresh oil fill. |
