All petrol, diesel and LPG automobile engines need regular top-ups of oil, which helps to keep moving parts lubricated and cool, as well as preventing build-ups of deposits which can harm your engine over time. 20w50 engine oil is a high-viscosity oil often used in vehicles that are prone to high temperatures, or engaged in high-stress activities like hauling. It makes an effective sealant and protects engine parts from friction wear. Bear in mind that all engines are different - refer to your owner’s handbook to find out the recommended grade of oil to use in your vehicle. Whatever type of car you drive, regularly changing your oil is a universal way to keep your engine in good shape for longer. As a general rule, you should change your engine oil every three months or 3,000 miles, whichever comes soonest.
