One of the simplest, most effective and inexpensive ways to help protect the life of your car-especially its engine-is to change the oil and the oil filter regularly. Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication and forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts. Without the cleaning action of new oil, carbon and varnish buildup would be toxic to the engine. Oil filters play a key role in providing that protection by helping to keep dirt, metal filings and sludge out of your oil, and out of your expensive engine. That's why experts recommend changing your oil and oil filter in your vehicle every three months or 5,000 kilometers, whichever comes first, to maximize engine protection. Always refer to your vehicle's owner manual for recommended procedures and maintenance schedules.
Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.
