Red Line 50304 Full Synthetic Gear Oil MT-90 75W-90 GL-4 (Quart)

Since most GL-5 gear oils for differentials are too
slippery for manual transmissions, Red Line offers these products that ensure
proper shifting while providing ultimate wear protection

75W90
GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
Popular
in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola
transmissions and Atlas transfer cases for Off Road
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

Appropriate
coefficient of friction for most manual transmission synchronizers
(other’s synthetic gear oils are often too slippery for proper synchro
engagement)
Red
Line offers lubricants to pinpoint nearly every transmission application
MT-LV,
MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
Excellent
gear and synchro protection, balanced slipperiness for easier shifting in
cold climates
Excellent
for high- and low-mile transmissions
Compatible
with petroleums and other synthetics
