Fleetguard LF3000 Combo Oil Filter 6-Pack Cummins ISC ISL B5.9 3318853

Fleetguard LF3000 Combination Oil Filter 6-Pack — Genuine OEM Full-Flow + Bypass Filter for Cummins B-Series, ISC 8.3L, ISL 9.0L, ISM, M11 & N14 Engines The Fleetguard LF3000 6-Pack is a case of six genuine Cummins Filtration combination spin-on lube filters that provide BOTH full-flow AND bypass oil filtration in a single canister. This unique dual-stage design eliminates the need for a separate bypass filter, simplifying your maintenance while delivering comprehensive oil protection. The StrataPore synthetic media delivers 98.7% filtration efficiency at 30 microns, capturing soot, dirt, metal particles, and carbon deposits before they can damage bearings, turbochargers, and cylinder walls. The full-flow section filters all oil passing through the engine at operating speed, while the integrated stacked-disc bypass section captures the finest contaminants on a slower, continuous-flow basis. Together, they provide deeper filtration than a standard full-flow-only filter. The LF3000 is the genuine Cummins Filtration replacement for Cummins OEM 3318853 and replaces four older Fleetguard filters: LF670, LF777, LF691, and LF3333. Buying a 6-Pack covers a full year of oil changes for a single vehicle, or one service cycle for a small fleet. Commonly used on school buses, RVs/motorhomes, medium-duty trucks, and industrial/construction equipment powered by Cummins B-series, ISC, ISL, ISM, M11, and N14 engines.

Feature LF3000 (This Product) LF9009 (Upgrade) Media StrataPore StrataPore + Venturi System Filtration 98.7% at 30 microns Enhanced — venturi creates secondary flow Service Interval Standard (10,000-15,000 miles) Extended (up to 20,000 miles) Physical Size Same Same (drop-in compatible) Price Lower Slightly higher Best For Standard maintenance schedules Fleets wanting extended drain intervals Both filters fit the same mount (2 1/4-12 UNS-2B thread). The LF9009 is a drop-in upgrade. If you want extended oil drain intervals, consider upgrading to the LF9009. When to Replace Replace at each scheduled oil change interval — typically every 10,000-15,000 miles for B-series and ISC engines under normal conditions. For severe-duty applications (stop-and-go school bus routes, dusty construction sites, heavy towing), shorter intervals of 7,500-10,000 miles may be required. The combination full-flow + bypass design means the filter works harder than single-stage filters and should never be extended beyond the recommended interval. What's Included 6x Fleetguard LF3000 Combination Oil Filters — packed in one factory-sealed case. Each filter is genuine Cummins Filtration with StrataPore media and integrated stacked-disc bypass section. Not aftermarket or repackaged. Why Choose the LF3000 Combination Filter? Standard oil filters provide only full-flow filtration — they catch contaminants above a certain size but let finer particles circulate. The LF3000's integrated bypass section continuously processes a portion of the oil flow through a stacked-disc media that captures ultra-fine particles too small for the full-flow section. This dual-stage approach provides cleaner oil throughout the entire service interval, reducing engine wear and extending component life. For Cummins B-series and ISC engines in demanding applications like school buses and construction equipment, the combination design provides insurance that single-stage filters cannot match.
