How often should the oil filter be replaced?

The replacement cycle of the oil filter element should be determined comprehensively based on the type of oil, equipment type and usage environment.

General replacement principle ‌

Change ‌ in sync with the engine oil

Under any circumstances, when changing the engine oil, the filter element must be replaced simultaneously ‌. The old filter element will retain contaminants and contaminate the newly added engine oil, resulting in a decrease in filtration efficiency ‌.

Youdaoplaceholder0 by type of engine oil

Mineral oil ‌ : every ‌3000-5000 kilometers or 6 months ‌‌

Semi-synthetic engine oil ‌ : every ‌ 5,000-7,500 kilometers or 6-8 months ‌‌

Fully synthetic engine oil ‌ : every ‌ 8,000-10,000 kilometers or 8-12 months ‌‌

Special environmental influences ‌

For dusty construction sites, frequent short-distance driving or high-temperature working conditions: the cycle is shortened to within ‌ 5,000 kilometers ‌‌

Diesel engines, due to their high cylinder pressure and more impurities, need to have their replacement cycle shortened by ‌20% to 30%‌‌ compared to gasoline vehicles

Special standard for construction machinery ‌

First replacement ‌ : the new machine has been in operation for ‌50 hours ‌ (after the running-in period) ‌

Regular cycle ‌ : every ‌300 hours of work ‌ (approximately 1.5 to 2 months) ‌

For equipment such as excavators and loaders, high-intensity operations require the following combinations:

High-pressure resistant filter element ‌ : metal housing anti-vibration design

Deep gradient filter paper ‌ : dirt holding capacity increased by more than 40% ‌

Key points to note ‌

Dual-filter element model ‌ : if the equipment is equipped with a coarse filter + fine filter dual system, it must be replaced simultaneously ‌;

Consequences of filter element failure ‌ :

The blockage causes the bypass valve to open, and unfiltered oil is directly injected into the engine ‌

Contaminants accelerate the wear of bearing shells and piston rings and shorten the overhaul cycle ‌;

The quality of the oil is related to ‌ : poor-quality engine oil can shorten the lifespan of the filter element by ‌50%‌‌.

Operation suggestion ‌ : Check whether the filter element sealing ring is intact during each maintenance to avoid oil pressure leakage due to seal failure ‌.
