Every automotive engine requires oil, but not just any oil. Modern engines are developed and built to stringent standards, necessitating the use of oils that fulfill very specific industry and manufacturer regulations in order to assure a long service life. Failure to use the correct type of oil and document its use may void your new-car guarantee.
Most late-model vehicles demand synthetic-blend or full-synthetic, low-viscosity, multi-grade, resource-conserving lubricants that reduce friction while increasing fuel economy. Choosing the right oil, on the other hand, is not always simple. The correct oil for your vehicle’s make and model must have the correct SAE viscosity grade, meet API, ILSAC, and/or ACEA performance criteria, and adhere to any unique specifications specified by the OEM or engine manufacturer. These parameters are described in your vehicle’s owner’s manual, and your auto repair shop can also give information on your vehicle’s recommended oil specs.
Oil change periods will vary depending on vehicle age, oil type, and driving circumstances. It used to be standard practice to change the oil every 3,000 miles, but with current lubricants, most engines now have suggested oil change intervals ranging from 5,000 to 7,500 miles. Furthermore, if your car’s engine demands full-synthetic motor oil, it might go up to 15,000 miles between oil changes! Because color cannot be used to determine engine oil conditions, stick to the factory maintenance schedule for oil changes.
