Overview

The Oil Change Calculator recommends engine oil change intervals based on driving conditions (city/highway), annual mileage, and oil type (conventional/synthetic). Regular oil changes are essential for maintaining engine performance and longevity.

Formula

Change Interval = Base Interval x Driving Condition Factor. Fully synthetic oil typically lasts 10,000–15,000 km or 1 year; severe conditions (frequent short trips, city driving) cut this to 5,000–7,500 km.

How to Use

1. 1Select the engine type (gasoline, diesel, hybrid).
2. 2Select the oil type (conventional, semi-synthetic, fully synthetic).
3. 3Select your primary driving condition (city, highway, severe).
4. 4Click 'Calculate' to see the recommended change interval in km and months.

Tips

• ✔Synthetic oil lasts longer per interval and can be more economical over time.
• ✔Frequent short trips, heavy stop-and-go traffic, and dusty environments qualify as severe conditions.
• ✔Regularly check oil level and color using the dipstick.
• ✔Diesel engines generally require more frequent oil changes than gasoline engines.
• ✔Follow the oil grade recommended in your owner's manual (e.g., 0W-20, 5W-30).
