How to Use the Right Auto Engine Oil
- 1). Consult your owner's manual or check with the the manufacturer or dealership that made your vehicle. Either should be able to tell you vehicle specifications and certification requirements to help guide you in selecting the best oil for your vehicle. This should include the recommended weight of the oil you should use.
- 2). Learn a little about the different certifications for motor oil. Most motor oils carry up to three certifications, including the most common, the American Petroleum Institute's starburst. Certifications indicate that the oil met the testing and content requirements. Other certifications include the International Lubricant Standardization and Approval Committee and European Automobile Manufacturers' Association.
- 3). Determine whether your car has a gas engine or diesel engine. The wrong oil placed in the wrong engine can spell disatser. Always verify your engine type and the oil that's being put in.
- 4). Consider your climate. One way certain motor oils can differ is in viscosity, or thickness. Lighter oils help improve fuel oil economy because they circulate more quickly, reaching upper engine areas faster when the car is first started and the engine is cold. In colder climates, heavier oils may not work as well because of very tight clearance between engine parts.
