Changing the oil is one of the most important things you can do for your car, whether it is brand new or has over 100 thousand miles on it. Oil helps lubricate the engine and prevents friction from occurring. Checking and filling up your car with oil should be a regular routine.
Instructions
1. Decide whether you need single grade or multi-grade oil depending on the climate that you live in. The oil is measured by its viscosity and how it handles temperature change. It will have a "W" at the end, which stands for "winter." Choose single grade--0W, 5W or 10W--if you live in a stable climate. Choose multi-grade--10W30 or 10W40--if you live in a climate that changes a lot.
2. Choose an oil grade that is based on the life of your engine. Choose lower viscosity such as 10W30 if your engine has less than 20,000 miles on it. Choose 10W40 or 10W50 if your car has more miles. 10W40 is a universal grade and is the most widely used type of oil.
3. Decide whether you want to buy conventional, synthetic or synthetic blend oil. Conventional is the cheapest but is the least efficient, synthetic is more expensive but more efficient, and synthetic blend is a mix of the two, and is cheaper in price than synthetic and better in quality than conventional.
