  • Features a stiffer pressure relief spring, which increases the maximum system oil pressure by 10%
  • Factory volumetric flow rate, around 6.8 GPM
  • Cast aluminum housing, CNC-machined and hard anodized
  • Compatible with factory GM oil pickup tubes/screens
  • 0.96 cubic inches per pump revolution
Part # M295

The factory LS oil pump suffers from cavitation above 6,200 RPM, which results in a drop in oil flow of nearly 1 GPM by 7,000 RPM. This cavitation can also aerate the oil, which causes drops in oil pressure and can result in oil starvation. This is why we do not recommend shifting any higher than 6,200 RPM with a stock engine. Engines that run at RPM's above 6,200 should use an upgraded Melling pump to prevent these issues.
Melling vs OEM Oil Flow Comparison Chart
The Melling M295 pump is a standard pressure, standard volume pump that is considered a suitable replacement for the factory oil pump (GM part # 1258665) and offers improved resistance against cavitation at higher RPMs.

This Melling oil pump is compatible with 4.8L and 6.0L Vortec iron block engines featuring Variable Valve Timing (VVT). This pump should not be used with engines that feature Active Fuel Management (AFM). Engines with AFM require a higher flow pump. See Melling part number 10355.

  • Cast aluminum housing, CNC-machined and hard anodized
  • Iron cover, CNC-machined and phosphate coated
  • Compatible with factory GM oil pickup tubes/screens
