Today's motoring ensures that your car will travel further than ever; modern engines mean that you are able to travel further. Maintaining a clean, well-running engine is essential. The oil and the oil filter need to be replaced regularly – the more miles you travel the sooner it will need to be replaced. Autosava offers a huge range of high quality oil filters, covering most car, van and commercial applications on the roads of the UK (We also offer oil filters for off highway and industrial applications).
Your oil filter has a direct influence on the performance of your engine, affecting power, reliability, efficiency, economy and emissions. Autosava suggest regular oil and filter servicing, always using quality parts.
OIL FILTER PERFORMANCE
The oil filter has a simple enough task, to remove dirt, debris and contaminating particles from the engine’s oil. If the particles suspended in the engine oil are not filtered adequately they combine together and a thick abrasive sludge is formed. This sludge not only affects the oils ability to flow, it directly acts on the engines friction surfaces and increases the wear rate. Metal to metal contact within any internal combustion engine is deadly; the inside of an engine is a violent place and damage is expensive to rectify (Although buying engine parts from autosava will reduce the cost). The engine oil is transferred around your engine by an engine driven pump. The pump aspirates the oil in the sump by sucking it through a strainer and pumps it under pressure through your engines lubrication system.
There are two different oil filter installations common to most cars and LCVs. Spin on oil filters are a self contained unit that is directly attached to the oil pump via a threaded tube. Cartridge oil filters live inside a canister that is permanently attached to the engine; these filters contain a disposable element. All oil filters are multi pass, i.e. the engine oil will travel through the oil filter repeatedly. The two installations are further subdivided into three separate categories of oil filters:
1. Full flow oil filters – The engine oil is pumped directly from the oil
pump, through the oil filter and onward through the engine, draining back to
the sump.
2. By-pass oil filters – The engine oil is pumped straight from the sump into
the engine. The oil filter is supplied a small percentage of the engines oil,
however, the design of the filter is such that it has a higher filtering
efficiency than a full flow filter. A by-pass filtering circuit will take
longer to filter the oil than a full flow, however, there is less restriction
in the lubrication circuit and
less risk of excessive localised oil pressure.
3. Combination oil filters – Heavy duty diesel engines use the combination approach, so that the engine oil and filter(s) have an extended service life. Approx 90% of the engine oil travels through the full flow circuit and 10% through the by-pass circuit, aeration, over heating of the oil and localised over pressurisation are better controlled.
