As engine technology advances, recommended oil change intervals have gotten longer. High quality oil in a well-engineered engine has led to extended intervals.
Here's the problem: With longer oil change intervals, it's for Rancho Cucamonga to follow them closely. Back in the day of 3 months or 3,000 miles (4,500 kilometers), if you went an extra month or an extra 1,000 miles (1,500 kilometers), your oil was still fresh enough that it didn't have time to build up much sludge.
But if your recommended interval is 6,500 miles (10,500 kilometers) and you go over another thousand, you're getting into heavy sludge territory.
Rancho Cucamonga area motorists absolutely need to follow mileage intervals very closely. And, Rancho Cucamonga drivers, don't forget your severe service schedule. If you do a lot of stop and go driving, short trips around the Rancho Cucamonga area, drive in dusty or polluted CA conditions, hot or cold weather or haul heavy loads, you're driving in severe service conditions. Is your driving closer to the regular schedule or the severe service schedule? It's your call as to when to change your oil to protect your engine.
If your car came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you shouldn't use the synthetic interval; you need to shorten it.
Dan's Mobil service advisors often report that when they talk to someone with 200,000 miles (300,000 kilometers) or more on their vehicle, the owner will say their secret is changing the oil on time. Please don't skip an oil change. Once sludge has started to build up, it's tough to get out.
