Changing your engine oil on a regular regular basis is extremely important and brings many benefits to the owner and vehicle.
Oil plays a huge part in keeping your engine in good shape and lubricated. Not only does it keep your engine in good shape but also has other roles like keeping the engine clean, its helps keep the vehicle cool, it reduces pollutants and stops the formation of sludge in your engines sump. If not changed at regular intervals or every 10,000 miles for petrol engines or 6000 for diesel engines you can end up wear and tear and a loss of power or god forbid engine failure.
When changed regularly the benefits include better engine stability by improving the life and functionality of the engine. When changed at regular intervals your engine will be clean inside and this will lead to better engine performance and it wont show as many signs of ageing giving it a longer life.
When oil is not changed regularly the engine starts losing its ability to lubricate and protect delicate parts within the engine resulting in friction between the moving parts and the engine starts to wear. The more friction there is the harder the engine has to work to overcome the friction. This will increase fuel consumption as performance decreases.
While on the flip side new oil is very smooth, creamy and viscous allowing engine parts to move smoothly with very little friction between the moving parts. This improves fuel consumption as the engine is now not working so hard and better mileage should be the end result. Regular oil changes also help to reduce noise made by the engine as parts move smoothly across each other producing less heat and friction and this will also help to keep your engine cooler.
Performance generally depends on the condition of your engine and if you service it regularly you can expect to get many more miles from your vehicle than if you don't. Changing your oil is a simple procedure and can be done on your driveway in about 15 minutes if you have a few tools and a jack. If you don't want to do it yourself you can take it to the many 1000s of garages and service centers dotted around the country.
