Benefits of engine coating: 1. Protection for the engine interior: Primarily lubricates and protects the engine walls, enhances wear resistance, and moderately extends engine performance. 2. Protection for the engine exterior: Mainly involves cleaning and polishing, preventing dust and other debris from adhering to the engine exterior. Additional information: I. Introduction to automobile engines: The automobile engine is the device that provides power to the vehicle, serving as the heart of the car, determining its power, fuel efficiency, stability, and environmental friendliness. II. Classification of automobile engines: Based on different power sources, automobile engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others.

As a frequent long-distance driver, I find engine coating most practical for its performance protection benefits. I always request this service during maintenance—it's like putting a protective suit on the engine, preventing carbon deposits and sludge from adhering to metal surfaces. Especially during hot summers, it noticeably improves heat dissipation efficiency, reducing excessive fan operation. Long-term, it prevents metal components from rusting and significantly improves oil fluidity. Older vehicles particularly benefit, with smoother idling being noticeable. Mechanics say this treatment can delay metal fatigue, extending major overhaul intervals by 20,000-30,000 kilometers.

Last time at the repair shop, I watched the technician applying coating to a new car and found the benefits quite comprehensive. The coating forms a protective film that isolates oil vapor and metal, significantly reducing friction damage during cold starts. The technician specifically pointed out to me that the mirror-like effect on the cylinder walls after coating reduces carbon buildup probability by 90%. During daily use, oil temperature fluctuations are smaller, making it much easier to climb hills with the AC on in summer. An unexpected bonus was that water stains don't stick to the cylinder surface during car washes, and cleaning fluid can be rinsed off directly.

The coating has a significant effect on reducing maintenance costs, which I deeply appreciate. The ceramic layer on the metal surface reduces the pressure in the cooling system, saving me over 300 yuan last year on antifreeze replacement. More importantly, with less carbon buildup, I no longer need to buy fuel additives every six months, and the spark plugs last longer. Recently, I've noticed a more responsive throttle on the highway, and the mechanic said it's due to reduced piston ring wear. The long-term savings on repairs could easily cover the cost of two more coatings.

The coating is mainly recommended for long-term engine health. The coating acts like an antioxidant, preventing white spots from forming on aluminum cylinder blocks during humid seasons. During one inspection, it was found that the throttle body of a four-cylinder car with the coating was much cleaner than one without, and the original metal color was preserved exceptionally well. The most noticeable benefit during daily driving is the quieter cold starts, and the engine fires up promptly even in sub-zero winter temperatures. An additional advantage is that mechanics often compliment the excellent condition of the engine bay, and it can add an extra thousand or so to the resale value.
