Fleetguard filters

Fleetguard is a filter brand of Cummins, the American maker of diesel engines. The range covers oil filters, fuel filters, air filters and filters for coolant and hydraulics, mainly for heavy diesel engines in trucks, construction machines, agricultural machines and generators. On forums Fleetguard is often named as the standard for Cummins engines.

What forums say

Most forum threads are in English and come from the American diesel world, from pick-ups and trucks to motorhomes. The tone is mostly positive. One user calls Fleetguard the standard on Cummins and uses the brand's oil, fuel and air filters. Another calls it a great filter that is fitted at the factory on many heavy trucks. Baldwin is named as an equal alternative for anyone looking for the cheapest option.

A forum member who says he used to work at Cummins Filtration writes that Cummins makes most Fleetguard filters itself. That is a claim by someone involved and therefore not neutral.

Filter media and jargon

The terms filter media and micron come up often in the discussions. The media is the material the filter is made of. For many oil filters Fleetguard uses the synthetic media Stratapore. One user points out that the LF3604 has cellulose rather than Stratapore and is still a very good filter. Another explains that microglass catches more particles at 10 micron than cellulose, but that flow matters too on an engine. One member thinks quality also depends on who made the filter.

Commonly mentioned part numbers

For the Dodge Cummins 5.9, forums mention the LF3000 series, such as the LF3894. One forum member reports that, according to a Cummins dealer, the LF16035 is an improvement over the LF3894. Recommendations differ by engine and year. For a tractor or machine, always look up the exact filter number with the engine maker.

Genuineness and warranty

Users often buy Fleetguard online on price and advise looking up the part number and choosing the cheapest reliable seller. Counterfeits are a warning point for air filters. In warranty cases forums advise caution with off brands, because a failure is then more quickly blamed on the filter.
