How often should I change my car's oil?

For your 2018 Honda Civic, the general recommendation for oil changes is typically every 7,500 to 10,000 miles if you’re using synthetic oil, which is common in modern vehicles. However, if you use conventional oil, the interval is usually shorter, around every 3,000 to 5,000 miles. It’s always best to check your owner’s manual for the manufacturer’s specific guidance, as Honda often provides tailored recommendations based on the engine type and oil used. Several factors can affect how often you should change your oil: 1. **Driving Conditions:** Frequent short trips, stop-and-go traffic, or driving in dusty or extreme weather can cause oil to degrade faster. In such cases, more frequent changes might be necessary. 2. **Oil Type:** Synthetic oils generally last longer and perform better over time compared to conventional oils, allowing for longer intervals between changes. 3. **Vehicle Age and Mileage:** Older engines or those with high mileage might benefit from more frequent oil changes to maintain optimal lubrication. 4. **Driving Style:** Aggressive driving or towing heavy loads can put extra stress on the engine and oil. In summary, while the typical interval for a 2018 Honda Civic with synthetic oil is around 7,500 to 10,000 miles, adjust this based on your driving habits and conditions. If you’re unsure, your owner’s manual is the best resource, or you can consult a trusted mechanic to tailor the recommendation to your situation. Regular oil changes are key to keeping your engine running smoothly and extending its lifespan.
