Is the wrong oil damaging the ‘Euro VI’ engine in your trucks or buses?

European emission standards (‘EURO’) limit the emission of harmful exhaust gases in an effort to slow down climate change. While the engines of your trucks and buses probably comply with the latest Euro VI standard, your engine oil might not. Discover why that’s a serious risk.
To keep up with the renewed Euro norms, vehicle manufacturers are constantly updating their engine designs. For example:
- Replacing indirect injection with direct injection results in better deposit protection and soot handling.
- The introduction of turbo charging offers greater protection against thermal degradation.
- Manufacturers also introduced aftertreatment systems to limit the emission of harmful particles.
What do developments in engine design mean for lubricants?
It’s no wonder that these developments also call for new and innovative lubricants.
New lubricants for Euro VI approved engines need to be ‘Low SAPS’ or ‘MidSAPS’. This means they contain a limited amount of Sulphated Ash, Phosphor and Sulphur. This is a key factor in the sustainable character of an engine oil.
What happens when you use ‘regular’ oil?
Many other engine oils are ‘Full SAPS’. Using such an oil would mean that the harmful SAPS particles clog the filter of your aftertreatment system.
Only with a Mid or Low SAPS engine oil, especially developed to meet the Euro VI standard, are your engines guaranteed to stay in optimal shape.
