In general, you do not need to change oil in your car after driving for nearly 3000 miles. The main supporters of the 3000-mile oil replacement are those who might make a profit for it, including quick-lube chains, repair facilities or service departments at several new-car dealers.

A couple years ago, changing oil as well as filter frequently was a really good idea, but most car manufacturers these days suggest interval of 7500 miles or even more. This is mainly due to technological advances in the material of the engine, the oil that comes into the engine and firmer tolerances as well.

For example, Porsche, Volkswagen and Ford suggest oil change every 10000 miles. The same could be applied for some engines in Toyota models such as the 2.5-liter 4-cylinder of Camry and the 1.8-liter 4-cylinder of Prius. BMW says that car owners might go up to 15000 miles after oil changes (for synthetic oil).

Those intervals can be different by engines as well as manufacturers, so you should consult the maintenance schedule or owner’s manual to learn how often you need to replace the oil in the car and what kind of oil to pump. You might be surprised. For example, we were really surprised to know that the 2.5-liter engine of Camry needs 0W20 synthetic oil.

Many car manufacturers recommend you to change oil more frequently in severe driving condition, such as sprawling in traffic jam, regular trailer towing, driving under extreme cold or heat weather, extensive stop-and-go driving, or regular driving in short distance in which the car’s engines does not reach their full temperature for operation.

Some auto companies, including General Motors and Ford, equip most of their cars with an oil life monitor. This device is based on engine temperature, vehicle speed, number of cold start, climate condition, and other important factors to tell the owner when it is the right time to replace the oil. They could all mention examples from drivers who claim that the oil life monitor showed they would move even longer distance than the suggested intervals of change.

If you are worried about driving 10000 miles or more after every oil changes, then you should do it for every half year, when you possibly should also get the tires rotated (you can also read the owner’s manual to see more explanation). General Motors recommends to replace your oil at least 1 time each year even when the warning light of service indicator does not come on. For longer suggested interval between oil replacements, it is more necessary to check the level of oil at least 1 time each month to be sure that you have adequate amount.

But it is probably wasteful to change oil each 3000 miles. In fact, many environmentalists claim that it also provides to the surfeit of used oil which needs to be disposed or recycled. Thus, a couple of states are attempting to deter the practice.

If the salesman at a quick-lube shop tells you that he is just trying to help when he suggests regular oil replacement, you should take this into consideration: Car manufacturers never want to put a customer in a situation that he suffers premature failure of the engine due to worn-out oil. If this situation actually happens, they would need to pay for repairing costs under warranty and possibly will lose a customer. However, bear in your mind that they are the ones who advise you to stick to a longer oil-change interval.
