OIL FILTERS

ABOUT SIERRA OIL FILTERS

Since 1948 Sierra has been a pioneer in the field of oil filtration. We are committed to providing your boat with the very best in engine protection with premium, application-specific oil filters. Our dedication is backed by substantial, ongoing research in filtration media, filter design and manufacturing processes. As a result, Sierra oil filter designs represent the very best of what we have learned after decades of research and development. No matter what type of boat you drive - Sierra has you covered.

OIL FILTERS/GASOLINE INBOARD - TECHNOLOGY

• Steel outer case for maximum strength. Won’t crush like aluminum.
• High efficiency filtration media.
• Anti-drain back technology (where applicable) helps keep oil in the system and limits wear and tear on engine start up.
• Epoxy coated canister prevents corrosion.
• Specifically designed to meet the high flow needs of today’s marine engine.

OIL FILTERS/DIESEL INBOARD - TECHNOLOGY

• Steel outer case for maximum strength. Won’t crush like aluminum.
• High efficiency filtration media.
• Anti-drain back technology (where applicable) helps keep oil in the system and limits wear and tear on engine start up.
• Epoxy coated canister prevents corrosion. Specifically designed to meet the high flow needs of today’s marine engine.
• Large capacity / high volume diesel specific filters.

OIL FILTERS/OUTBOARD - TECHNOLOGY

• Canister filters made from epoxy coated steel for added strength.
• Cartridge filters designed to OEM specifications.
• High flow filter media designed for the demands of the marine environment.
• Anti-drain back technology (where applicable) to help keep lubrication from draining back into the crankcase, providing extra protection on start-up.

OIL FILTERS/GASOLINE INBOARD - MAINTENANCE

• Replace filter after first 20 hours of engine operation.
• After first 20 hours filters are to be replaced every 50 hours of operation or at a minimum of once yearly.
• Add a coating of engine oil to sealing gasket prior to installation to prevent filter from “freezing” in place and allow for easy removal.
• Use marine rated oil filters and not automotive filters. Marine filters generally filter at a higher micron level and also allow for more oil flow at higher rpm’s than automotive filters.
• Use the correct grade and weight of marine rated oil to protect your engine.
  Follow engine manufactures recommended procedures on oil and filter changes. In general, be sure to run engine to operating temperature to aid in removing all oil from crankcase and keep debris suspended in oil for removal.
• Never run engine out of the water without a properly installed flushing device in place.
• Do not over-tighten filter.
• Be sure and run engine and check for leaks after any oil service.
