Extending your vehicle’s oil drain interval is not as important as protecting your engine’s parts throughout the entire interval. Driving conditions like stop and go driving, driving on dusty, gravel, or salted roads, driving in extreme temperatures, or towing may actually necessitate a shorter drain interval. Extending your oil drain interval may also void your vehicle manufacturer’s warranty.
You should always follow your vehicle manufacturer’s recommendation for oil drain intervals. Make sure to use a product that will offer you complete protection for the duration of your vehicle’s interval, like Pennzoil Synthetics, for top engine performance.
