Should Engine Oil Be Changed After Six Months?

[ElizabethMarie]

Engine oil does not necessarily need to be changed after six months. Here is the relevant information: 1. The replacement interval for engine oil depends on the type of oil used, as well as the owner's driving habits and operating environment. Generally, different types of engine oil have different replacement intervals. 2. Conventional engine oil typically begins to oxidize after three months of exposure to air. If conventional oil is used and the vehicle has not been driven for about three months, the oil should be changed promptly. Under normal driving conditions, conventional oil starts to degrade after 5,000 kilometers, semi-synthetic oil begins to degrade around 7,500 kilometers, and full-synthetic oil starts to degrade between 10,000 to 15,000 kilometers.
