Just as your engine is the heart of your vehicle, oil is the lifeblood, it lubricates and protects your engine from wear and damage. Ensuring that your oil is changed on a regular basis, and using the best grade for your vehicle, is crucial to keep your vehicle running properly. Oil flows into the engine from other areas accumulating dust, dirt, and other particles, then through the oil filter which helps trap these contaminant particles. However, over time the filter can become clogged, reducing the amount of filtration the oil receives, the oil over time also loses its viscosity. Meaning it gets harder to get to where it needs. Oil also helps draw heat from parts of the engine, if these parts are covered in a build-up, these parts stay hotter longer. Eventually your engine will become less efficient, impacting performance of both MPG and BHP, and in certain cases internal engine damage. As the oil filter is a permanently sealed unit, you are unable to visually check performance and there is no warning light or gauge to remind you to check, you may not notice your oil filter needing replaced. Which is why we advise regularly changing your filter as well as your oil.
