Oil changes: how often and what they cost
The old 3,000-mile rule is out of date for most engines. Here is what AAA and price guides say, plus what matters in Utah.
- Most engines: every 5,000 to 7,500 miles. (Source: AAA Automotive)
- Conventional oil: about every 5,000 miles. Synthetic blend: about every 6,000. Full synthetic: 10,000 to 15,000 miles. (Source: AAA Automotive)
- Change oil at least once a year even if you drive little, per AAA. (Source: AAA Automotive)
- Your owner's manual and oil-life monitor are the final word. (Source: AAA Automotive)
Severe service: often the Utah case
AAA lists severe service conditions as mostly short trips (5 miles or less), extremely hot, cold or dusty climates, sustained stop-and-go driving, and heavy loads or towing. If those describe your driving, follow the severe schedule in your manual. Newer cars with oil-life monitors shorten the interval automatically. (Source: AAA Automotive) Utah winters, summer heat in the south, dusty roads and towing can fit those categories; check your manual to decide.

Oil level and warning lights
AAA notes that low oil can cause engine damage your warranty may not cover. (Source: AAA Automotive) Your owner's manual explains how the oil level should be checked; a shop can check it at any service visit. If the red oil pressure light comes on, do not keep driving: stop as soon as it is safe and have the vehicle inspected by a certified (ASE) mechanic. See oil pressure light or oil-life alert.
