Filtration

Engine Oil Filters

Full-flow and bypass lubricating oil filters in spin-on and cartridge form, including the combination units used on larger diesel engines.

Features

  • Full-flow filters protect the engine on every pass; bypass filters clean a small share of flow to a finer rating and extend oil life.
  • Anti-drain-back valves keep the filter primed at shutdown, which shortens the dry period at the next start.
  • The bypass valve setting inside the filter matters on cold starts, where thick oil would otherwise burst the media.
  • Change interval follows the oil specification and duty cycle together, not the filter alone.
  • Cutting open a used element at overhaul says more about engine condition than an oil sample on its own.
