75W-80 GL4/5 fully synthetic transmission oil for modern passenger car manual gearboxes with excellent cold shift performance and improved efficiency.
75W-80 GL4/5 fully synthetic is developed for modern passenger car manual transmissions where low cold viscosity, smooth cold shifting, and high efficiency are key. It is designed for current manual gearboxes that require an efficient yet durable multigrade transmission oil.
Thanks to its fully synthetic base of PAO and esters, the oil remains stable even under demanding temperature fluctuations and is especially suited for drivers who value smooth shifting in winter as well as reliable protection under continuous load.
This makes it a modern, efficiency-focused solution for suitable BMW, Ford, Mercedes, Fiat, and PSA manual transmission applications.
Suitable for modern passenger car manual transmissions where API GL-4/GL-5 or corresponding approvals such as BMW MTF LT, Ford WSS-M2C200-D2, MB 235.10, or PSA 9730 are required.
Why is 75W-80 so popular in modern manual transmissions?
Because it offers an excellent balance of cold shift comfort and everyday efficiency.
Can GL4/5 be used in any gearbox?
Only if the manufacturer explicitly allows this specification.
What are the benefits of a fully synthetic base?
Primarily improved temperature stability, smoother shifting, and longer performance reserves.
