The engine is a very important part of your car, not to mention that it is expensive to repair or replace, which is why manufacturers add oil filters to protect it. Though small, these components actually perform a huge role in prolonging the life of your engine by ensuring the oil is filtered clean before circulating back to the engine. Given the nature of their function, these filters accumulate contaminants, which means that they also need to be changed on a regular basis. However, choosing replacement filters can be difficult especially if you do not have the right information in hand. In this regard, here is a check list of the things that you should look into when buying oil filters:
- Hole Size, Threads, and Gasket
First, check out the new filter’s hole at the bottom and ensure that it is of the same diameter as the stock filter previously installed on your vehicle. Then, make sure that it also has similar threads, which can be of metric or Society of Automotive Engineering (SAE) standard. Moreover, check if the gasket is positioned in a way that matches the original. Keep in mind that getting a filter with hole size, threads, and gasket with different dimensions as the original will result in oil leaks, which will eventually complicate to more serious mechanical problems. So, make sure to check these areas carefully.
For an oil filter to be more effective, it should have up to 50% extra surface usable area of its membrane. Also, know the material used in the membrane, whether it is cellulose, micro-glass fibre, or synthetic media, as each has different oil movement restriction and filtering capabilities from the others.
- Anti-Drainback Valve
Today’s oil filters usually include an anti-drain back valve, which prevents the oil from draining when your car’s engine is turned off. This will ensure better oil pressure when you start your car once again, allowing the oil to reach the important engine parts sooner, preventing damage due to lack of lubrication.
- Bypass Valve
In the event the filter is clogged, this component allows the oil to still pass around the filter and ensure it reaches the vital parts of the engine for lubrication. See to it that your new filter offers this fail-safe feature.
