20W-50, API SF/CC

20W-50, API SF/CC is a mineral motor oil used mainly for older, worn-out engines (often Soviet-made cars or classic cars manufactured before the 1980s).

It is designed for moderate to high ambient temperatures:

20W-50: High viscosity (thick oil), which provides stable pressure in the system of a heated engine, reduces oil consumption for fumes and protects parts with high mileage.

API SF/CC: Obsolete classification. SF means compatibility with gasoline engines (until 1988), and CC - for moderately boosted diesel engines (mostly atmospheric).

It is strictly not recommended to use this type of oil in modern (especially high-speed or turbocharged) engines due to their increased demands, thin oil channels and non-compliance with modern environmental standards.

Benefits of use:

✓ meets the requirements of most equipment manufacturers;

✓ good lubricating, detergent and anti-corrosion properties;

✓ helps protect against sludge formation at low temperatures and oxidation at high temperatures;

✓ compatibility with all engine seals;

✓ ideal price-quality ratio;

✓ detergent properties and acidity control help maintain reliability, prevent engine and bearing corrosion and reduce downtime;

✓ stable chemical composition of the oil throughout its service life;

✓ protection of parts from corrosion and other chemical influences;

✓ reliable protection against wear and polishing of cylinder walls ensures increased engine service life;

✓ prevents the formation of sludge and deposits on pistons;

✓ protects the engine and bearings from corrosion;

✓ prevents polishing of cylinder walls;

When choosing oil, be sure to pay attention to the operating manual for machinery and equipment, which clearly states the necessary oil parameters - viscosity, conditions of use and possible substitutes.
