Racing gearbox and differential lubricant
100% Synthetic – Ester based
Specially designed for racing vehicle gearboxes : speed way, rallye, raid…
All mechanical transmission, synchronised or not synchronised gearboxes, gearbox/differential, transfer gearboxes and hypoïd differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed.
Motul 300 Gear Oil
STANDARDS API GL4 and GL5 / MIL-L-2105D
100% synthetic extreme pressure lubricant for an efficient anti wear protection, a better resistance at
high temperature and a longer life time.
0% shear loss : Unshearable oil film in extreme conditions.
Stays in 90 grade after KRL 20 hours shear test as requested by SAE J306 Standard, July 1998 update
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 easier gear shifting when the gearbox is cold.
Less effort required on the gear lever to shift the gears.
Suitable for any type of seal and yellow material used in gearboxes design.
Oil change: According to manufacturers' requirements and adjust according to your own use.
