Liqui Moly Top Tec 6600 SAE 0W-20 Full Synthetic Motor Oil, 5 Liter

Boasting exceptional low-friction performance, this fully synthetic motor oil is designed to deliver superior outcomes. The innovative additive technology ensures excellent protection against wear, superb engine cleanliness, and greater oxidation stability. Notably, the low viscosity of this oil facilitates excellent cold-start behavior, improves engine efficiency, and reduces fuel consumption.

The BMW Longlife-17 FE+ approval specifically targets the mitigation of low-speed pre-ignition (LSPI) risk. LSPI refers to the spontaneous ignition of the air-fuel mixture within the combustion chamber at low speeds, occurring before the ignition spark. This phenomenon can lead to engine knocking and potentially severe engine damage, although the underlying mechanisms are not yet fully understood.

By using the appropriate motor oil, however, this risk can be effectively reduced. Until now, no BMW models have been exclusively compatible with this Longlife-17 FE+ oil specification, which is also backwards-compatible and may be required when an older Longlife standard is specified for use.

It is important to note that this type of oil must be used under certain circumstances, as it is not compatible with all other oil types. The BMW Longlife-17 FE+ approval is intended to address the LSPI issue, which can have serious consequences for engine performance and longevity if left unmanaged.

In summary, this fully synthetic motor oil offers exceptional low-friction performance, excellent cold-start behavior, improved engine efficiency, and reduced fuel consumption. Its innovative additive technology provides superior protection against wear, enhanced engine cleanliness, and greater oxidation stability. Crucially, the BMW Longlife-17 FE+ approval is specifically designed to mitigate the risk of low-speed pre-ignition, a phenomenon that can lead to significant engine damage if not properly addressed.
