Is it necessary to add a running-in agent during the first maintenance?

The first maintenance does not require adding a running-in agent. The content of the first maintenance includes: 1. Changing the engine oil and oil filter, cleaning the air filter, and checking whether the generator belt and wiper blades are damaged; 2. Checking whether the levels of various fluids are normal; 3. Checking whether the tire pressure is normal and whether there is any abnormal wear, bulging, or damage to the tires; 4. Inspecting the car chassis, including checking for scratches on the brake pads, brake discs, connecting rods, ball joints, and CV joints; 5. Checking whether all switches and lights in the car are working properly. The precautions for the first maintenance are: 1. Make an appointment in advance; 2. Record any faults or questions encountered while driving and inform the staff during the maintenance registration.

I recently bought a new car, and during the first maintenance, the dealership asked if I wanted to add a break-in additive, claiming it would help the engine break in faster. I checked my owner's manual and found no mention of it. Many experienced drivers online also say that modern engines are precision broken in at the factory and don't need any additives. Saving those few hundred bucks is enough for me to maintain my tires twice or fill up the tank. The dealership pushes those products just to make money, and adding them might even clog the fuel lines. The real tasks for the first maintenance are changing the oil, replacing the filter, and checking the brake system. I advise new car owners not to waste money and focus on basic maintenance—your car will run smoothly for two to three years.

Having driven for over thirty years, I always advise young people to stay calm when they're recommended break-in additives during their first car service. In the old days, older engines needed them, but now with advancements in automotive manufacturing technology, engine components fit together so precisely that the break-in process is simulated and completed at the factory. Adding break-in additives during the first service is not only unnecessary but can sometimes cause engine noise or premature aging. The smart way to save money is to first check the manual—if it doesn't mention it, skip it. Instead, spend the money on high-quality engine oil or battery checks. The key is to ensure the overall health of the vehicle, so you can drive long distances with peace of mind.

First service with break-in additive? I think it's unnecessary. Modern engines are exquisitely designed with excellent surface hardening treatment from the factory, resulting in minimal wear. Break-in additives merely play an auxiliary role but may alter oil composition and cause adverse reactions. If the manual doesn't require it, skip it for peace of mind and effort. Focus the first service on oil change, air filter replacement, and checking tire pressure and lights.
