Rosneft Express is a washing oil with a high content of detergent-dispersant additives. The oil is produced from a high-quality mineral base of deep cleaning and f highly effective additives. Widely used be individual car owners, and in mechanics of the service station.
Rosneft Express is designed for washing the oil system of petrol and diesel engines of domestic and imported cars before changing engine oil. The oil is recommended to be applied before each change of engine oil as follows: warm up the engine to operating temperature; drain old motor oil; pour oil flushing and allow the engine to idle for 15 minutes; Drain the liquid; replace the oil filter; pour in fresh oil. In case of severe contamination, it is recommended to repeat the procedure. It is not recommended to give increased load to the engine during the washing process.
Approvals and specifications
• The detergent components ideally remove carbon deposits, mechanical impurities and low-temperature deposits from lubrication channels and working surfaces of the cylinder-piston group, gas distribution mechanism and slide bearings;
• Highly effective dispersant additives, during washing, keep insoluble wear particles and components of unburned fuel (soot) in a stable suspension state, preventing the oil system channels from clogging up even in the presence of a large amount of deposits;
• Perfectly compatible with the materials of the oil seals and removes various deposits from them, thus prolongs unattended engine operation period and reduces the risk of oil leaks.
