Engine oil is permanently exposed to extreme thermal and mechanical stress, causing it to consume and contaminate itself over time. For example, through combustion in the engine, dilution with fuel or condensation water, natural oil ageing and mechanical abrasion. Among other things, this encourages the formation of deposits due to combustion residues and can lead to serious consequences in the long term:

• loss of compression and performance
• poor exhaust emission values and risk of failing the emissions test
• increased fuel and oil consumption
• deteriorated lubricity
• lubricant no longer reaches the individual lubrication points in the engine
• increased engine wear up to the breaking of the timing chain and engine damage

To ensure optimum lubricity and protect the engine from damage, it is therefore unfortunately not enough to simply top up with fresh oil. Only a regular oil change, i.e. replacing the old, used oil with new oil, guarantees safe engine function and increases the service life of the engine.
