Experts recommend changing the oil and oil filter in your vehicle every 3 months or 3,000 miles, which ever is first. It's an essential way to maximize engine protection. Oil changes at 7,500 miles are usually too long an interval for most common driving conditions. Refer to your car manual.

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 3 months or 3,000 miles (5,000 kilometers), whichever comes first, to maximize engine protection. (Always refer to your vehicle's owner's manual for recommended procedures and maintenance schedules.)
