Red Line formulates its gear oils specifically for the appropriate coefficient of friction for most manual transmission synchronizers (other’s synthetic gear oils are often too slippery for proper synchro engagement)
Rather that offering a one product suits all across GL-4 & GL-5 Red Line offers lubricants to pinpoint nearly every transmission application
75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
Offers quicker shifts, perfect synchronizer coefficient of friction
Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
High performance gear protection and longer synchro life
Eliminates notchy shifting, even when cold
Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40, and 15W40
Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified

Weight 0.890 kg
Dimensions 10 × 10 × 23 cm
