Myth 1: Think that engine oil is just "lubricating oil".
Have you ever thought that car oil only existed to lubricate the engine?This is a fairly common misconception. Engine oil does more than just give the engine an oil massage. In fact, the task of oil is quite onerous, in addition to lubrication, it also has to cool the engine, remove impurities from the engine, reduce friction, prevent corrosion, and so on. Choosing the right engine oil is like choosing an all-round "engine butler" for your car.
Myth 2: Ignoring the influence of viscosity
Viscosity is a big issue, and it's not just important when it comes to the physics of Newtonian and non-Newtonian fluids. In the case of motor oil, viscosity refers to how well it flows at different temperatures. In extremely cold weather, oil that is too viscous can make it difficult to start the engine, and too thin in high temperatures can reduce lubrication. So, knowing and choosing the right oil for your local climate is the equivalent of choosing the right clothing for your engine.
Myth 3: Ignoreapiwithsnand other specifications
This is not the kind of "hand-to-hand" API, but the American Petroleum Institute (API) standard. The letter combinations such as SN, SM, SL, etc., which you may often see on engine oil bottles, are actually the performance grades of engine oil formulated by the API. Choosing the right oil for your car is like putting on the right sneakers for your car and letting it run on the road!
Myth 4: Ignore brand and quality
Some people may think that all engine oils are the same, just buy a cheap one. This is a big mistake!Different brands of motor oils vary greatly in terms of formula and quality. Choosing a well-known brand and certified engine oil is just as safe as choosing a brand for your own food purchases, not only will your engine be healthier, but it will also give your car more face.
Myth 5: Ignoring the maintenance cycle
Motor oil is not a one-and-done thing, it also has a lifespan. Changing the oil regularly is a necessary step to prolong the life of your engine. Of course, service intervals may vary from model to model, but in general, it's wise to follow the manufacturer's recommended service intervals. Imagine what would happen to your body if you had been using expired foodIsn't it a little uncomfortable?For your car, using expired oil can also make it quite uncomfortable.
In short, unveiling the five misunderstandings of car oil selection is like finding a safe channel for your car, so that it can get rid of many potential engine crises. Don't get caught up in the tricks, start with the right oil, and give your car a healthy and long-lived engine massage!
