Car maintenance with fully synthetic engine oil or semi-synthetic engine oil is good?

A lot of car enthusiasts are very concerned about the oil, one is related to the cost of car maintenance, oil is a big head; two is because after buying a car is inseparable from the maintenance, maintenance of the most conventional project is the engine lubricant replacement.

So, is it better to use full synthetic engine oil or semi-synthetic engine oil for car maintenance?

What is fully synthetic motor oil? What is semi-synthetic motor oil?

What we usually call fully synthetic motor oil refers to 100% PAO (polyolefin) or synthetic esters of high-quality motor oil products, usually in the oil drum above the label "synthetic" words.

Semi-synthetic motor oil is a lubricant made from international Class III base oil, which is purified by hydrofission technology on the basis of mineral oil. Specifically, it is made by mixing mineral oil and full synthetic motor oil in the ratio of 4:6 and adding some additives.

Advantages of fully synthetic motor oil The stability and anti-degradation ability of fully synthetic motor oil is incomparable to other mineral oils. Especially with engine supercharging technology, when the supercharging parts start working, the engine torque will increase exponentially. At this time, the oil film covering the engine crankshaft has to withstand a shear force several times higher than before, and the higher quality fully synthetic engine oil can fully meet the requirements of the oil film. This is one of the reasons why some high-end automobile brands specify the use of a brand of fully synthetic engine oil. From the price point of view, in 4s stores or quick repair stores, the price of a conventional 4L barrel of mineral motor oil is mostly 150-200 yuan, semi-synthetic in 250-300 yuan, fully synthetic in about 350 yuan. Combined with the oil change cycle to calculate, full synthetic motor oil cost-effective some more.

Summary.

The car is a combination of tens of thousands of parts together in the machinery, the engine parts with the precision requirements of especially high, which will inevitably produce friction, one of the roles of the oil is to reduce friction, in addition, the oil also has a cooling, cleaning, air sealing, rust and corrosion prevention, shock absorption buffer and other functions.

I think we must choose a good oil, to give the car the minimum wear and tear.
