The number of miles you can go over your scheduled oil change depends on several factors including the type of oil used, your driving conditions, and your vehicle's specifications.

• Modern vehicles with conventional oil typically recommend oil changes every 5,000 to 7,500 miles. If you use full-synthetic oil, this interval can extend up to 15,000 miles between oil changes

• Driving conditions affect how far you can safely go over an oil change. Highway driving in good weather may allow you to exceed the recommended interval by a few thousand miles, while city driving, severe conditions (such as stop-and-go traffic, extreme temperatures, towing, or short trips), or heavy loads require more frequent changes and less tolerance for going over the interval

• Going significantly over the recommended oil change mileage risks engine damage due to oil degradation, reduced lubrication, and buildup of contaminants. Warning signs to watch for include dark, gritty oil, burning oil smell, engine knocking noises, or dashboard oil warning lights, which indicate that an oil change is urgently needed

In summary, while you might be able to go a few thousand miles over the recommended oil change interval under ideal conditions, it is best to follow your vehicle's owner's manual and oil-life monitoring system recommendations to avoid engine damage. Generally, going more than 1,000 to 2,000 miles over the recommended oil change interval is not advisable without checking oil condition
