What is Block Exemption?

Block Exemption is a set of EU and UK Commission laws designed to stop unfair competition. It allows vehicle owners to have the freedom to choose where their car is serviced or repaired outside the main dealership network without voiding the manufacturer’s warranty.

Prior to 2003, car owners in the EU risked voiding their vehicle warranty when their vehicles were serviced or repaired in workshops not belonging to the vehicle manufacturer or its dealer network.

What Block Exemption means in practice

Block Exemption means that motorists can have their vehicle serviced or repaired in any chosen workshop without invalidating their manufacturer’s warranty, providing that it is undertaken to the same standard as the manufacturer. So, if a vehicle is still under manufacturer warranty, an independent garage can service it as long as they:

  • Follow the manufacturer’s service schedule
  • Use parts and fluids that meet the manufacturer’s specifications
  • Carry out the work to the correct standard
  • Keep records of the service

What this has to do with engine oil

Block Exemption covers spare parts, which means that workshops do not have to use vehicle manufacturer original equipment parts (including lubricants) to ensure a vehicle maintains its warranty. Parts can be sourced from any supplier as long as they are of appropriate or ‘matching quality’. Oil specification is one of the most important requirements under Block Exemption.

Manufacturers specify exact oil standards (for example VW 504 00 / 507 00, BMW LL-04, Mercedes 229.52, etc.). Independent garages must use an oil that meets these specifications.

If the correct oil specification is used:

  • The vehicle warranty remains valid
  • The service is compliant with manufacturer requirements

If the wrong oil is used:

  • It could invalidate the warranty
  • It may cause engine damage or excessive wear

Why this matters for independent garages

Block Exemption allows independent workshops to compete with main dealers, but it also means they must be careful to use fully approved/acknowledged or specification-compliant oils.

That’s why lubricant companies often highlight oils that meet or carry official manufacturer approvals/acknowledgements, because this allows garages to service vehicles confidently and within warranty requirements.
