Royal Purple 29606300 Details

Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid.

Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drivetrain. Max Gear virtually eliminates both gear and bearing wear—even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.

This product landed in my 2015 Silverado Z71 differentials, and knowing the reputation of RP why not try and see. I did and you pay for a good product and this one did not disappoint. comparing to OEM RP seems to free the drive train up allowing better gas mileage not quite a mile per gallon but at least between a 1/2 mpg or so, all seems smoother cannot say quieter because I had no noises to begin with. Long term we will see and so far money well spent.
