Is it acceptable to delay an oil change by one month?
2 Answers
Delaying an oil change by one month is generally acceptable. Below are specific methods for selecting motor oil for your car: 1. Performance selection: If you prioritize long-lasting oil performance, Mobil oil is a good choice; if you focus on engine cleanliness, Shell lubricants are recommended; for stronger oil film toughness, Castrol is advised. 2. Driving conditions: For frequent driving in congested areas, older vehicles, or long-distance heavy-load transportation, it's appropriate to use lubricants with slightly higher viscosity. 3. Engine type: Naturally aspirated engines can use mineral or semi-synthetic oils. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-grade lubricants with better fluidity, preferably full synthetic oil.
I used to wonder if it's okay to delay an oil change by a month, and I've tried it a few times myself because I was too busy to go to the shop. Once, I delayed it for over a month, and the engine started making strange noises. Upon inspection, I found the oil had turned black and thick, with reduced lubrication leading to faster component wear. Now, I’ve learned my lesson: engine oil must be changed every 5,000 kilometers or six months. Otherwise, accumulated contaminants and oxidation can shorten the engine’s lifespan. If you absolutely must delay the change, I suggest checking the dipstick first—if the oil is still clear and at the proper level, you might stretch it a few days, but it’s best not to take the risk. Repairing engine damage costs far more than an oil change. After all, oil is the lifeblood protecting your engine’s heart—it shouldn’t be neglected. Like me, developing a habit of regular maintenance ensures peace of mind and safety.
