About the product
- The BMW Longlife-17 FE+ approval is intended specifically to reduce the risk of LSPI. LSPI stands for low speed pre-ignition and means that the mixture ignites spontaneously in the combustion chamber at low speeds before the ignition spark.
- This can lead to motor knocking and therefore serious motor damage. This phenomenon is entirely understood yet. But this risk can be reduced by using the right motor oil.
- Up until now, there have been no BMW models which only require this type of oil with Longlife-17 FE+ and are compatible with any other oil. Furthermore, this type of oil is backwards compatible and must under circumstances be used when an older Longlife standard is specified for use.
