Which is better Shell or Castrol? Isn t that the word of mouth about the same?

Shell and Castrol oil are relatively well-known brands in engine oil, and the quality of general engine oil is definitely okay, but there are quite a lot of series of Castrol and Shell engine oils, if you want to have a good driving experience, you must buy higher-end engine oil. I've also used some engine oil, and it's a bit loud at high speeds, but the quality isn't good. Since the use of GT Magic Red engine oil, this problem is gone, not only the sound is less at high speeds, but the power is also more sufficient, and the driving experience is much better, no wonder many high-end cars are using it.

Both Shell and Castrol are imported brands with their own unique technologies, and Shell's main selling point is that it is derived from natural gas. The base oil is purer than the traditional base oil, the molecular structure is more balanced, and it is relatively better than the general three types of base oils in all aspects. Shell's main focus is on cleaning power, especially the cleanliness of the engine, the inside of the engine will be cleaner when using gold shell for a long time, and the sludge and carbon deposits that the engine is prone to produce can be filtered out, so that the engine can maintain a good working condition for a long time.

And the power response is also very good, which can be reflected in the engine with high assembly accuracy. When you step on the throttle, there is an immediate power response. The selling point of Castrol products is the good flow performance at low temperatures and the good protection of the engine from cold starts.

In areas with low temperatures, vehicles with difficult cold starts, or older vehicles, Castrol is also a good choice. The main focus of the company is anti-wear performance, Castrol EDGE is just like the advertisement. If it is not started, protect it first.

Generally speaking, the oil film is relatively strong. The engine can also be protected in advance when the car starts the next day. BMW, Audi has to use maintenance oil is also Castrol.

The anti-wear is relatively strong. Suitable for the kind of driving with a big foot on the accelerator. Personally, I think cleanliness is the foundation of the engine, so I prefer Shell!

Personally, I think Shell's engine oil is better.

For many people, Castrol oil is not particularly outstanding in terms of performance, and in terms of the balance of the six functions of the oil, Castrol oil has the most average overall quality. However, Shell motor oil is favored by people for its unique patented technology and superior cleaning performance.

The advantage of Shell lubricants is their cleaning power, which can help keep the engine clean and improve fuel efficiency by generating dirt, sludge and carbon deposits after a period of use. It is characterized by high anti-wear properties, which can extend the service life and greatly improve the efficiency of the system.

Taking Shell's most popular Helix Ultra oil as an example, this product adopts Shell's unique patented technology PurePlus technology and power clean dispersion technology, the former can convert natural gas into a crystal-clear base oil that is almost free of common impurities, and the latter makes Shell oil have super cleaning efficiency, low volatility, better oxidation stability and better low temperature characteristics, which can fully meet the protection of the engine, and is essential for extending engine life, reducing maintenance costs and oil consumption. Improving fuel economy is a good help.

Shell oil is good.

Shell proprietary base oils. Shell has its own synthetic base oils and uses natural gas-to-liquids technology to remove carbon deposits from the engine during the life of the vehicle, so it is more suitable for engine types that are prone to carbon deposits.

Shell Helix Ultra oil is suitable for vehicles with high carbon deposits because of its best-in-class cleaning power, which can fully remove the carbon deposits generated by the engine's operation, preventing the engine from working properly due to excessive carbon deposits.

As the two major brands with high recognition in the world's automobile market, they have their own advantages but also different disadvantages. Shell oil is easy to increase oil impurities in the process of cleaning carbon deposits, and Castrol engine oil cannot clean carbon deposits well because of its complex composition, but in general, Shell is better.

How many grades are there for Shell oil?

There are three grades of Shell engine oils: fully synthetic, semi-synthetic and mineral oils. Of course, of the three grades, Shell oils, which are fully synthetic, are the best.

Shell matte oil is divided into five categories according to the different packaging colors, which are gray shell, blue shell, yellow shell, red shell and white shell. Each color represents a different purpose and level, and is also used for different vehicles.

In its macro closure, the gray shell refers to the extraordinary Heineken and HX8, both of which are fully synthetic oils; Blue shell is a semi-synthetic oil; The yellow shell has HX6 and HX5, HX6 is a semi-synthetic oil, and HX5 is a mineral oil; Red shell HX3 and white shell HX2 are mineral oils.
