DAF Lubricants is an integral element in the DAF Genuine Parts line-up and in our efforts to improve customer retention. Thanks to the extensive range of DAF lubricants, we can offer you lubricants for every PACCAR engine model.
The DAF Lubricants range covers engine oils of all types, from high performance to fuel saving; from mineral to synthetic. Driveline oils also form an important part of the DAF Lubricant range and include gear oils for manual, automatic gearboxes and differential oils. To cover the full programme we offer you also a complete range of coolants.
All selected DAF Lubricants fulfill five crucial functions to meet the high DAF standards and approval process.
The metal parts within engines move at very high speeds and are made to extremely tight tolerances. So a proper lubrication is significant.
Although the tolerances between the piston and cylinder wall are extremely tight, there is a minute gap. The oil helps to seal this gap, maintaining the compression ratio and therefore engine power.
A lesser known but vital function that oil provides is heat transfer. It carries the heat away from the hotter regions of the engine and dissipates the heat as it passes through the oil cooler.
Detergents contained in the oil help to prevent the formation of deposits on hot surfaces. This keeps the engine clean, particularly the pistons and prevents piston rings from sticking.
5. Rust prevention
Combustion in the engine creates acids which can cause rust and corrosion. The oil contains special detergents which neutralize these acids, preventing rust and corrosion.
