Regular oil changes are essential for maintaining your vehicle's engine health. This comprehensive guide covers everything you need to know about oil changes, from the best intervals based on your driving habits to choosing the right oil type for your specific make and model.\n\nModern engines have different requirements than older models. Most newer vehicles can go between 5,000 to 7,500 miles between oil changes when using synthetic oil. However, if you frequently drive in severe conditions (stop-and-go traffic, extreme temperatures, towing heavy loads), you may need more frequent service.\n\nWhen selecting oil, pay attention to viscosity ratings like 5W-30 or 10W-40. The first number indicates cold temperature flow, while the second number represents thickness at operating temperature. Always consult your owner's manual for the manufacturer's recommendation.
