Fleetguard LF3325 Spin-On Oil Filter | Heavy-Duty Cummins Diesel Engine Oil Filter
Description
Heavy-duty diesel engines are built to run hundreds of thousands—even millions—of miles, but only when they're protected by clean, properly filtered engine oil.
Every hour your engine operates, microscopic metal particles, soot, carbon deposits, and combustion byproducts circulate through the lubrication system. Without an effective oil filter, these contaminants accelerate wear on bearings, camshafts, crankshafts, pistons, and other critical engine components.
The Fleetguard LF3325 Spin-On Oil Filter is a genuine heavy-duty replacement oil filter engineered for a wide variety of Cummins industrial, vocational, marine, agricultural, construction, and on-highway diesel engines. Designed to meet Cummins' demanding filtration standards, the LF3325 provides dependable contaminant removal, high oil flow capacity, and durable construction for demanding operating environments. It utilizes cellulose filtration media, features a 1½-12 UNF mounting thread, and is rated for 84 L/min (22.19 GPM) of oil flow. Fleetguard identifies the LF9325 as the premium upgrade for applications using the LF3325.
Whether your engine spends its life hauling freight, powering industrial equipment, or operating in severe-duty conditions, routine oil filter replacement is one of the most important maintenance items you can perform.

Why Oil Filtration Matters
Engine oil does much more than lubricate moving parts.
It also carries away:
- Combustion soot
- Carbon deposits
- Microscopic metal particles
- Oxidized oil residue
- Dirt that bypasses the air filtration system
Without proper filtration, these contaminants continue circulating through the engine where they can accelerate wear on critical internal components.
A quality oil filter continuously removes these contaminants while maintaining consistent oil flow throughout the lubrication system.
Glacier Tech Tip
Many heavy-duty diesel engines spend long hours idling, towing, or operating under constant load.
These conditions increase soot production and place additional demands on the engine oil.
Even if the oil still appears clean, the oil filter is continuously collecting contaminants that aren't visible to the naked eye.
Replacing both the oil and filter at the recommended service interval helps maintain proper lubrication, supports consistent oil pressure, and promotes long engine life.
Why Choose Genuine Fleetguard?
Fleetguard has been engineering filtration systems alongside Cummins engines for decades.
The LF3325 is built to provide the proper balance of:
- Reliable contaminant removal
- Consistent oil flow
- Heavy-duty construction
- Durable sealing
- Long service life
Fleetguard filters are developed to meet Cummins' performance standards, giving fleet operators and owner-operators confidence that their engines are receiving the protection they were designed to have.
Applications
The Fleetguard LF3325 is commonly used on numerous heavy-duty Cummins diesel engines, including:
- Cummins L10
- Cummins M11
- Cummins N14
- Cummins KT Series
- Cummins KTA Series
- Cummins KV16 and related industrial applications
It is commonly found in:
- Class 8 highway trucks
- Vocational trucks
- Construction equipment
- Agricultural equipment
- Industrial power units
- Marine applications
- Generator sets
Fleetguard Upgrade:
- LF3325 → LF9325 (recommended premium replacement)
Important Notes
- Genuine Fleetguard LF3325 spin-on oil filter.
- Verify fitment using your engine serial number before ordering.
- Replace the oil filter whenever changing engine oil.
- Inspect the filter sealing surface before installation.
- Lubricate the gasket with clean engine oil prior to installation.
- Hand-tighten according to Fleetguard installation guidelines.
Common Failure Point
Engine wear rarely results from one catastrophic event—it usually happens gradually as contaminants circulate through the lubrication system.
Microscopic soot, metal particles, and abrasive debris can slowly wear bearings, journals, camshafts, and piston assemblies over thousands of operating hours.
Replacing your oil filter at every scheduled oil change helps reduce circulating contaminants and supports long-term engine durability, whether your equipment operates on the highway, in the field, or on the jobsite.
Complete Your Preventive Maintenance Program
Protect your heavy-duty Cummins engine with quality maintenance components:
- Fleetguard Premium Oil Filters
- Fleetguard Fuel Filters
- Fleetguard Air Filters
- Fleetguard Coolant Filters
- Fleetguard Crankcase Ventilation Filters
- Glacier Diesel Power Diagnostic Tools
- Glacier Diesel Power Fluid Service Accessories
Routine preventive maintenance is one of the most cost-effective ways to maximize engine life, reduce downtime, and keep heavy-duty diesel equipment operating at peak performance. Using genuine Fleetguard filters helps ensure your engine receives the same level of filtration trusted by Cummins for demanding commercial and industrial applications.
