Full Answer

It is not only vehicles that use synthetic oil that can go for more than 3,000 miles in between oil changes. In fact, almost every auto manufacturer now recommends oil changes after every 5,000 miles. For instance, Toyota recommends having the oil changed after 5,000 miles for all vehicles that use petroleum-based oil and 10,000 miles for most of their engines that require synthetic oil.

Jaguar has the longest oil change intervals of any car manufacturer, as they recommend all of their vehicles get an oil change every 15,000 miles. This is true of all newer model Jaguar vehicles, no matter whether they use synthetic or petroleum oil.

Although they are generally much more expensive, synthetic oils often translate into less frequent oil changes. This is because synthetic oil can withstand much more heat and pressure than conventional oil before it finally starts to break down. Still, synthetic oils are not necessary for most vehicles.
