Is it necessary to use new car protectant?

New car protectant is necessary to use. It can protect the car engine and reduce the wear caused during engine operation. After purchasing a new car, there will be a break-in period where many small metal burrs or raised metal debris exist on internal parts. Using new car protectant can reduce and repair engine wear marks and micro-pores, decreasing engine wear by up to 95%. Engine protectant is a maintenance agent that effectively reduces wear or corrosion on engine components, inhibits the formation of deposits like gum and sludge, prevents oil oxidation, thickening, and acidification, and extends engine lifespan. The main functions of engine protectant include anti-wear, lubrication, noise reduction, and improving engine power and fuel efficiency.
I think new car protectants aren't really that necessary—it mainly depends on your driving environment and personal preference. A protectant is essentially a chemical coating applied to the car's paint or interior surfaces, forming a protective barrier against UV rays, oxidation, or scratches. New cars typically come with factory-applied protection that lasts a year or two without issues. If you frequently drive in rainy, snowy, or dusty conditions, a protectant can help maintain the car's shine longer and reduce the frequency of waxing. However, the cost isn't low—a quality bottle can run hundreds or even over a thousand yuan, and the results may not be significantly better than regular hand waxing. I've owned several new cars and noticed that protectants do keep the shine longer, but if you drive gently and wax frequently, saving that money is worthwhile. Overall, it's more of a luxury than a necessity—it depends on how much you value protecting your car.
Using a new car protectant is more of an indulgence, in my opinion. When I first bought my new car, I tried it too. After applying it, the paint became smooth with strong reflections, looking especially dazzling under sunlight, as if the car had just left the dealership and maintained that fresh look longer. It does a decent job at preventing rain stains and bird droppings, making maintenance a bit easier and saving the hassle of extra weekend car washes. However, there's really no need to insist on it—new cars are inherently durable, and protectants are just a bonus at best. They're pricey, and regular wax costing just a few dozen bucks can serve as a substitute. I've also seen friends who didn't use protectants but kept their cars looking brand new even after five years—it all depends on how you maintain them. My advice: if you want to show off a bit, give it a try; otherwise, regular car washes are sufficient.
