VP Classic® Gear Oil GL-4 SAE 80W-90



Product Description

VP Classic® GL-4 Gear Oil SAE 80W-90 is an API GL-4 lubricant designed for use with ‘yellow metals’ in synchronizers, thrust washers, bushings and other components typically found in classic manual transmissions and transaxles. VP applies a 3-pronged approach to lubricant design for remarkably stable oils that allow race engines of all types to achieve extraordinary performance and durability:
  1. Improve the ability of the oil to cling to metal components by improving viscosity through the use of select base oils with polar characteristics.
  2. Add a balance of multiple anti-wear chemistries beyond ZDDP into the oil that adhere to metal surfaces to create a protection layer.
  3. Add unique friction modifiers that reduce fluid- to- fluid friction and surface friction between the oil and moving metal components to unlock horsepower and torque.
Multiple engine builders, including Al Moody Race Engines have performed dyno tests of VP’s engine oils and have documented real horsepower gains. Many of these same engine builders have performed documented video teardowns to inspect wear on engines ranging from 355 cubic inch dirt track motors to 3,000hp big block marine engines. The engine internals look virtually new and can be reused beyond traditional replacement intervals.
