Not as long as the service is conducted by a qualified mechanic following the manufacturer’s specifications.
A quality filter will not save your engine from excessive wear if there
is prolonged use of poor quality oil. Low quality oil generally means the oil
additives deteriorate quicker, putting more stress on the engine.
Make sure you use good quality oil and filters.
Make sure correct filter was installed as per instructions.
(a) Check old sealing
gasket was removed from engine mounting base plate and that plate isn’t damaged
(b) Ensure filter is correctly fitted with new sealing gasket.
(c) Check threaded stud isn’t damaged or loose.
To provide strength to the filter due to high air flows and provide fire protection in case of backfires.
The air filter
should be changed in relation to operating environment of vehicle, eg in hot,
dusty conditions more regular frequent change period is required. In any case
recommend change every 01 month irrespective of conditions or distance travelled.
A blocked air filter can significantly increase fuel consumption. In addition, it can increase cylinder bore wear due to excessively high fuel to air ratios.
Because it is the most important filter. Unfiltered air (inducted contamination) will cause excessive engine wear.
Generally the carbureted system operates at low pressure and has relatively low flow. Filters are often nylon bodied.
EFI filters are metal bodied, and designed to handle higher pressures and flow. The media can also differ between filter types.
Full flow is where 100% of the oil passing through the same media before
entering the engine. Bypass filters are more restrictive and take a portion of
the oil and filter out smaller particles that can or have passed through the
full flow filter.
Common in heavy duty applications.
Should the oil filter become blocked, the valve will open allowing oil to flow into the engine. (Unfiltered oil is better than no oil).
It stops oil from draining out of filter and oil galleries when the engine is shut down and aids quick flow of oil to engine on start up. Not all filters require anti drain back valve due to the construction of the engine.
A measure of the pore size in the filter media. Expressed as either
‘Nominal’ or ‘Absolute’. Nominal Rating relates to the percentage of particles
at a given size that a filter can capture ie. 10 microns at 90% means it will
remove 90% of particles 10 microns in size. Absolute refers to the removal of
all particles at a given micron size and larger ie. 20 micron absolute means
100% of particles 20 microns or greater will be captured.
The lower the micron rating, the greater the efficiency and hence the amount of dirt that is captured.
Common oil filter micron rating is approximately 30. (Human hair is approximately 70 microns)
When comparing different filter brands micron rating, you need to make sure that the same test procedures have been followed.
A micron a measurement equaling one millionth of a meter.
Given the importance of efficiency, life and flow, regular filter changes with a good quality filter provide optimum performance and engine life.
How easily air, oil or fuel flows through the filter. Minimizing resistance to flow ensures that the engine is never starved of air, oil or fuel. Poor flow in a filter deprives engines of their vital needs, causing them to work harder, lose power and create rapid engine wear over shorter periods.
The percentage of dirt that a filter removes. The filter paper or \'media\' determines what the oil, air or fuel has to pass through and where the dirt is trapped. The more twists and turns a particle of dirt have to take, the more likely it is to be captured.
The higher the efficiency, the higher the % of dirt retained by the filter. Filters are least efficient when new and become most efficient just before "plugging".
To separate out and prevent potentially contaminant particles from entering engine. Air and fuel – dust particles and moisture. Oil – metal particles, sludge and carbon.
