The frequency of oil changes depends on several factors, including your vehicle’s make and model, driving conditions, and the type of oil used. Here’s a general guideline:
1. Follow Your Car Manufacturer’s Recommendation
Most modern cars recommend oil changes every 5,000 to 7,500 miles for conventional oil.
Many newer vehicles with synthetic oil can go 7,500 to 10,000 miles or even up to 15,000 miles (check your owner’s manual).
Some cars have an oil life monitoring system that calculates when a change is needed based on driving habits.
2. Consider Your Driving Conditions
Severe driving conditions (frequent short trips, extreme temperatures, towing, stop-and-go traffic, dusty roads) may require more frequent changes (every 3,000 to 5,000 miles for conventional oil).
Normal driving (mostly highway, moderate climates) allows for longer intervals.
3. Type of Oil Matters
Conventional oil → Typically 3,000 to 5,000 miles.
Synthetic blend → 5,000 to 7,500 miles.
Full synthetic oil → 7,500 to 15,000 miles (some high-performance synthetics last even longer).
4. Time-Based Changes (If You Don’t Drive Much)
Even if you don’t hit the mileage limit, change your oil at least once every 6–12 months, as oil degrades over time.
