Choosing the right lubricant for your car is no easier than picking out a well-fitting suit, and involves a combination of the following car models, road conditions, seasons, and the driving experience you're after.
First of all, to consider according to different models, you can refer to the vehicle manual about the API quality level recommendation. (API grade represents the grade of engine lubricant quality. Gasoline lubricants, for example, are divided into SM, SL [Review Picture Forum], SJ, SH, SG, SF, etc. The letters after S are in alphabetical order, and the further back they represent the higher the grade, the better the quality of the lubricant.) Usually, experts will recommend a lubricant that is one grade higher than that recommended in the vehicle's manual.
Middle and high-end models with high power, high rotational speed and harsh working conditions naturally have higher requirements for lubricants, especially the need for stronger antioxidant stability and anti-shear stability of the lubricant. Such as Ferrari F1 car, speed up to 18,000 rpm, the need for lubricants shear resistance is very strong, such as Shell lubricants have 3 times the ordinary oil shear stability; accelerate quickly (seconds between the speed from 0 to 200 km / h) need to lubricants have a fast flow rate, in the vehicle start-up moment, the oil flow to the need to protect the place of the formation of a protective film of oil; large power, engine temperature Up to 300 degrees, the lubricant is required to have good anti-temperature oxidation stability.
For economic vehicles, many owners believe that the reliable brand of semi-synthetic oil or ordinary mineral oil is enough, but if the road conditions or the owner of the pursuit of better driving experience or hope to extend the engine life, then you can raise the lubricant level.
Road conditions are also a factor in oil selection. For city cars, frequent starts and stops during peak hours make the engine often in the wear and tear, experts suggest that city cars can choose synthetic lubricants such as Shell Extraordinary Helix. This fully synthetic lubricant has small molecular particles, a smooth structure, and a fast lubricant flow rate that reaches the pistons, cylinder walls and camshafts in the shortest possible time, where lubrication, cooling and protection are needed.
In addition, high speed running can help fuel fully combusted, the oil circuit is smooth, which is good for the engine. However, prolonged high-temperature high-speed operation is likely to lead to the production of sludge, which will cause the engine to run poorly, increased noise, idle speed shaking increased. At this point, lubricants with strong cleaning ability are also the right choice. For example, Shell Helix has 5 times the cleaning ability of ordinary mineral oil.
The choice of lubricants should also pay attention to seasonal changes. Summer consumers in most parts of the country can choose 5w-40 or 10w-40 lubricants, and can be appropriate according to the situation to shorten the oil change cycle, wheel bearings with a higher drip point of grease, transmission and differential for summer thick gear oil, brake fluid with a high boiling point of the brake fluid.
