When it comes to oil changes, things are really changing. Most newer vehicles require synthetic oil, and while it costs more than conventional oil, it doesn't need to be changed as often.
When conventional oil was the only game in town, you changed your oil every 3,000 miles/5,000 km. But as technology in newer vehicles has rapidly changed, so has oil technology. Synthetics have been around since the seventies. Even though they start with a conventional oil base, they are engineered in a chemical processing plant with properties that allow them to keep your engine lubricated at very high temperatures. They are more uniform and consistent.
Synthetic oil doesn't break down as easily, so it lasts longer than conventional oil. And synthetic oil can flow more easily, even in extremely low temperatures. As you can see, it has performance advantages at both temperature extremes.
Generally, in recent years automakers have been shipping most of their vehicles with either synthetic oil or a synthetic blend. Blends are cheaper and have many of the advantages of synthetics. Another reason synthetic oil is being used in many newer vehicles is its ability to flow more easily improves efficiency.
It's important to follow your vehicle manufacturer's recommendations when you have your oil changed, so our service adviser can see what options you have for your vehicle. Many newer vehicles come with specific recommendations for synthetic oil. If you live in an area with wide temperature extremes or do a lot of stop-and-go driving, synthetic oil can offer advantages.
Older vehicles can do fine with conventional oil, but it will have to be changed more than synthetic oil. Also, if you have an older vehicle with more than 75,000 miles/120,000 km on it, it can be more prone to leak and burn oil. Some synthetic oils are designed to protect those high-mileage vehicles better than conventional oil, and yours may benefit. See what your service adviser thinks.
