Engine oils for passenger cars (Petrol & Diesel)

An engine is a complicated machine with hundreds of moving parts that operate over a wide range of temperatures and stresses. The oil must withstand operating conditions to protect the engine against wear, corrosion and build-up of dirt and deposits. Choosing the right engine oil can sometimes be complicated. This is because vehicle manufacturers have different engine designs to meet increasingly stringent emission requirements. The requirements for motor oil differ between manufacturers, which means that content, viscosity or quality must be adapted to these requirements. Different requirements mean that the number of motor oils has increased significantly.
