How to identify high-quality motor oil?

Two completely different oils can meet all the necessary specifications and tolerances; this does not necessarily mean that they have the same quality. The specifications set just the minimum requirements.
Due to toughening the rules for environmental protection, it is becoming more and more expensive for manufacturers to develop new engine oils, so they cannot be cheap. The use of high-quality oils will prevent problems with engine operation.

Famous oils for good quality car engines:

  • Bizol;
  • Elf;
  • Total;
  • MPM;
  • ZIC;
  • Shell;
  • Eurol;
  • Statoil;
  • XADO;
  • Nanoprotec.

The main causes of increased engine wear are:

improper oil behavior during the cold start of the engine, insufficient fluidity of the oil, which does not allow the oil pump to properly distribute the oil in the lubrication system. What engine problems can bad engine oil create?

  1. piston rings, cylinder surfaces, crankshaft bearings, camshaft, valve bushings, etc. will not be properly lubricated;
  2. increased oil consumption may occur, often this is not only a problem in leaking or worn bushings but also in increased volatility of the oil if it is of poor quality;
  3. problems may arise with the crankshaft: due to poor oil supply, or its insufficient viscosity. 

Why could bad engine oil be dangerous?

The oil may be contaminated with foreign particles or with a high content of air bubbles. In low-quality oil, organic acids form at high temperatures, which can lead to corrosion of engine parts. Deposits accumulate in this oil, which over time can destroy pistons and other engine parts.

Why should car engine oil be of high quality?

The right, high-quality motor oil reduces friction, reduces fuel consumption and improves engine performance. Protects friction motor vapors from corrosion and wear, extends the life of the engine and improves engine efficiency. The proper engine oil absorbs heat and keeps the engine from deformation and overheating, can increase engine power by ensuring tightness and the right level of compression.

What should be quality motor oil?

A minimum of 7 additives must be present in high-quality motor oils: antiwear, anti-corrosion, anti-foam, anti-oxidizing, detergent, extreme pressure, and viscosity.
Oils for automobile engines with high quality tolerate heat better, they have a higher viscosity index and higher oxidation resistance. Such manufacturers as, for example, Bizol, Elf, Total, MPM, ZIC carry out numerous laboratory tests for corrosion, oxidation, chemical compatibility with various materials, dispersion, pressure, the stability of components during storage and shear resistance. Shell, Eurol, Statoil, XADO, Nanoprotec, and others carefully conduct expensive bench tests and field trials, which are vital stages in the development of lubricants.

Properly selected high-quality engine oil can significantly reduce fuel consumption.
