Oil Change Interval Guide
Find the right oil change interval for your vehicle based on oil type, age, and driving conditions.
Your Vehicle & Oil
Change Oil Sooner If You Notice:
- Oil dipstick shows dark, gritty, or very low oil
- Burning oil smell inside the cabin
- Engine knocking or louder-than-usual operation
- Oil pressure warning light or engine warning light
- Visible oil leaks under the vehicle
- More than 12 months since last change (regardless of miles)
Oil Type Comparison Chart
| Oil Type | Normal Interval | Severe Interval | Best For |
|---|---|---|---|
| Conventional (Mineral) | 3,000–5,000 mi / 3–6 mo | 3,000 mi / 3 mo | Older vehicles, budget-conscious |
| Synthetic Blend | 5,000–7,500 mi / 6 mo | 3,500–5,000 mi | Mid-range, light trucks, SUVs |
| Full Synthetic | 7,500–15,000 mi / 12 mo | 5,000–7,500 mi | Modern engines, performance, extreme temps |
| High-Mileage Synthetic | 5,000–7,500 mi | 3,500–5,000 mi | Vehicles over 75,000 miles |
Is 3,000 Miles Still the Rule?
The 3,000-mile oil change interval was standard advice when conventional oil and older engine tolerances were the norm. Modern full-synthetic oils and improved engine designs mean most new vehicles can safely go 7,500–10,000 miles between changes — some up to 15,000 miles. Always consult your owner's manual, which is more authoritative than any generic recommendation.
What Counts as Severe Driving?
Severe service means: frequent short trips under 5 miles (engine never fully warms up, moisture builds in oil), extreme temperatures, stop-and-go city driving, towing or hauling heavy loads, dusty or unpaved road conditions, or extended idling. In severe conditions, change oil at half the normal interval regardless of oil type.
