How to maintain the engine

1. Using appropriate quality grade lubricant

Gasoline engines should be used in SD-SF grade gasoline engine oil according to the intake and exhaust system attachments and use; diesel engines will have to use CB-CD diesel engine oil level according to the mechanical load, a standard not lower than the manufacturer requirements prevail .

2. Periodic replacement of oil and filter

Any change in the quality level of the lubricating oil occurs in the course of the oil quality will be. After a certain mileage, performance deterioration, the engine will bring all sorts of problems. In order to avoid faults, it should be combined with a regular oil change conditions, and moderate oil (generally dipstick cap as well). When the oil filter from the oil through the pores of the solid particles and viscous material accumulated in the filter. Such as filter plugging, oil can not be through the filter, the filter will burst open or the safety valve, the bypass valve through, still the dirt back to the lubricating parts, prompting engine wear, increased pollution inside.

3. Keep good crankcase ventilation

Now most of the gasoline engine are equipped with PCV valve (crankcase ventilation) promote engine breathing, but the blow-by gas pollutants "will be deposited around the PCV valve, the valve may be clogged. If clogged PCV valve is the reverse of polluting gases inflow of air filters, pollution filters, the filter reduced ability inhaled the mixture is too dirty, polluting more crankcase, resulting in increased fuel consumption, increase engine wear and even damage to the engine. Therefore, subject to regular maintenance PCV , remove PCV valve surrounding contaminants.
