Motul Gear 300 transmission oil is an ester based full synthetic formulated for high performance and racing vehicles. Works extremely well in 5-speed and 6-speed synchronized transmissions (non-limited slip formula). The LS version has friction modifier additives for plate type limited slip diffs.
100% synthetic lubricant for all mechanical transmission of high performances and racing cars. For synchronized or not synchronized gearboxes, gearbox/differential, transfer gearboxes and hypoid differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed. 0% shear loss: Unshearable oil film in extreme conditions. Very high lubricating power which decreases friction and wear. 90 grade at hot temperature to provide outstanding oil film resistance at hot temperature and/or to reduce transmission noise. Fluid at low temperature to allow comfortable gear shifting.
What is the difference between Gear 300 and Gear 300 LS?
The LS formulation has added slip modifiers that allow clutch type limited slip diffs to function more effectively. However, the use of the standard Gear 300 is preferred in a synchronized transmission because the slip modifiers can reduce synchronizer performance. Therefore in a synchronized AWD transmission fitted with a clutch type front or center LSD some experimentation may be necessary to determine which fluid will give the best overall performance. Subaru 5-speed transmissions seem to be particularly sensitive to fluid selection due to the fact they are often being pushed to their limits and suffer from high operating temperatures.
Gear 300 LS available here.
What should the oil change interval be?
It will depend on the type of operating environment. A high performance road application where the gearbox or differential is heavily stressed should probably change the fluid every 15K miles. The addition of a clutch type limited slip diff will necessitate even more frequent changes due to the contamination of the oil with metallic or carbon dust generated by friction plate wear. In a motorsport application it should probably be changed after every event or even mid event if it is an endurance race or long rally.
Each bottle contains 1L/1.05Quart of SAE 75W90 fluid.
