Can I Bring My Own Engine Oil for Maintenance at a 4S Shop?

You can bring your own engine oil for maintenance at a 4S shop, but the 4S shop will charge corresponding labor fees. Types of Engine Oil: There are three types of engine oil used in cars: mineral oil, full synthetic oil, and semi-synthetic oil. These three types of oil have different usage cycles. Generally, mineral oil has a usage cycle of 5,000 kilometers, semi-synthetic oil lasts about 7,500 kilometers, and full synthetic oil can last up to around 10,000 kilometers. Car Maintenance Items: The main item in car maintenance is replacing the engine oil. Engine oil is a consumable product; after a certain period of use, its performance degrades, and its lubricating effect diminishes. Therefore, it is essential to regularly maintain the car and replace the engine oil. When changing the oil, car owners should select the type of oil based on the engine type. Additionally, the oil filter should be replaced simultaneously to prevent impurities from mixing into the oil.
I used to drive to 4S shops for maintenance, and experience tells me that bringing your own engine oil is quite complicated. Many 4S shops discourage car owners from bringing their own oil because it's one of their main profit sources. If you use your own oil, they can't guarantee their profits. On the other hand, if the oil you bring is of poor quality or doesn't match the car model, it may cause engine damage, and the 4S shop will shirk responsibility, saying it's not their fault, and the repair costs could even double. Once, I tried bringing my own purchased oil to the shop, but they outright refused, saying the manufacturer's policy didn't allow it, so I had to obediently use their branded product. I suggest you call ahead to ask about the specific shop's attitude—some smaller shops might be flexible, but you'll likely have to sign a liability waiver to avoid future disputes. A car is a mechanical treasure; proper maintenance can extend its lifespan, so don't risk it just to save a few bucks.
As a car owner who always wants to save money, bringing my own engine oil to a 4S shop sounds like a great deal, but in practice, it's quite troublesome. 4S shops usually don't welcome this practice, citing concerns over oil quality and potential liability if issues arise. I once did the math—bringing my own oil could save me a couple hundred yuan, but the shop often charges extra for labor or service fees, which pretty much cancels out the savings. More importantly, it might void the engine warranty, as manufacturers typically require the use of specified products. So, I usually only consider asking about it during non-critical maintenance. If you're determined to try, first check your car model's oil specifications, choose genuine, reputable brands, and communicate directly with the shop to see if they have any flexible policies. A healthy car runs smoothly—don't compromise safety over small savings.
