Four Common Oil Change Myths Debunked

Posted April 21, 2022

An oil change is essential for all vehicle engines as it keeps them lubricated, thus running smoothly. Not changing your vehicle’s oil results in complete engine failure as the oil helps remove excess heat from the engine. Since oil changes are a very important part of the existence of a car, there are multiple myths about the issues of an oil change.

According to, auto mechanics help diagnose car problems with the brakes, engines, and climate control systems. This post discusses some of these myths as we debunk them with facts.

1. Oil should be Changed Every 3 Months or after 3000 Miles

Most people are taught to conduct an oil change after 3000 miles or three months when buying a car. Failing is said to fill the oil with damaging sludge. The myth is further supported by local oil changers who may even leave a sticker on your car’s windshield showing you how to change the oil after three months.

The rule no longer applies. Today’s advancement in vehicular technology has improved oil quality, where cars can now last 7 to 10000 miles without an oil change. Some cars are equipped with old-life indicators, which indicate the time for an oil change. Some car owners’ manuals come with an optimal oil replacement plan. However, check your oil levels often to avoid extremely low levels.

2. Change Your Oil if it Turns Black

Fresh oil is usually amber in color and looks very fresh. After some time, the oil turns black, which people assume is dirt. This notion is wrong and is the opposite. Most refined oils use detergent additives that turn dark when the oil disperses the debris that causes sludge on the engine. It suspends them within the oil so that they cannot form a layer. Dark oil ensures the engine is lubricated and protects the inside metals of the engine from sludge.

3. It is Wrong to Switch Between Conventional and Synthetic Oils

A common myth about an oil change is that you cannot return to conventional oil if you use synthetic oil. Synthetic oil has been chemically manufactured. It is a total myth since both types of oil blend together normally. The switch causes no damage.

Oil change myths are common and should be debunked. Conduct research or consult auto mechanics before believing all you hear about engine oil changing processes.

4. Synthetic Oils Cause Leakage

When chemically manufactured oil first came to the market in 1970, it caused oil leaks. Today, they are made to prevent oil leaks and are thus way better than the conventional ones. An oil change using synthetics is, therefore, safe.
