Top Tec 6600 0W-20 Synethtic; ACEA C5, API SN+ RC, ILSAC GF-5; Approvals: BMW LL-17 FE+, MB 229.71, Opel OV0401547; Recommended for Chrysler MS-12145, Fiat 9.55535-GSX, Ford WSS-M2C947-B1

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 not 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 not compatible with any other oil. Furthermore, this type of oil is not backwards compatible and must under no circumstances be used when an older Longlife standard is specified for use.
