Red line lipid synthetic oil is the first choice for evaluating the extreme oil of OPTION fans, which is definitely worth it.
REDLINE engine oil has been active in the track all over the world, such as NASCAR race, Formula One race, Tour de France, linear acceleration race, various cross-country races of automobiles and motorcycles, high-speed speedboat race, land speed race, snowmobile race, high-speed airplane race and so on. In actively participating in these racing competitions, REDLINE Engine Oil has achieved excellent results and become the best engine oil company participating in racing activities in the world.
Red Line Company was established in 1979. Its founder, PETER FILICE, is a lubricant engineer. He and another founder, Tim Koellgen, are very strict about the quality of engine oil, so they used their professional knowledge to develop their own engine oil and founded REDLINE Engine Oil Company.
At first, they only provided high-quality synthetic engine oil for off-road motorcycles, greatly improved the performance of the racing car with red line engine oil, and won. Racing is the best publicity tool for REDLINE engine oil. In the mid-1980s, drivers of various racing cars began to enter the door of victory after switching to REDLINE engine oil, which made REDLINE famous in the United States. And people who gradually became interested in racing began to choose REDLINE all over synthetic engine oil for their cars. Various additives suitable for long-term use in roads are added to the "base oil" which can withstand high running, high temperature and high wear resistance during racing, and become a lubricating oil series for red-line roads. Therefore, the red line lubricant is not only durable, but also can improve the horsepower of the car.
Lubricating oil consists of base oil and additives, of which base oil accounts for more than 95%.
The types of base oils are divided into the following five categories:
First, traditional solvent refining mineral oil;
The second category, hydrocracking mineral oil;
Both of them are called mineral oil. The base oil of mineral oil is the residual base oil after fractionating useful light substances (such as aviation oil, gasoline, diesel oil, etc.). In the process of crude oil refining (the rest is asphalt). In essence, it uses inferior components in crude oil, which contains thousands of different mixture molecules. No matter how refined the refining technology is, all the bad products and impurities cannot be removed.
The third category, highly hydrocracked or hydroisomerized wax;
The raw materials of this base oil, like the first two, are the most deceptive in the market now. Representative Castrol began to use VHVI (very high viscosity index), a class III base oil, instead of the original formula of PAO, and labeled it "synthetic oil", but now many domestic brands are copying it. With the improvement of processing technology, VHVI now has: 1DW (hydrocracking-isodewaxing) patent of Chevron Company; ExxonMobil obtained MSDW (hydrotreating-hydroisomerization and hydrocracking-selective dewaxing) patents; XHVI (Hydroisomerization to Produce Ultra-high Viscosity Index) is a patent of Shell Company, and now it is called synthetic base oil. Among them, ExxonMobil semi-synthetic oil basically adopts MSDW technology, which is called synthetic technology.
The fourth category, polyalphaolefin (PAO);
Poly (α-olefin) (PAO) is a patented technology of ExxonMobil, which is refined into a basic liquid composed of macromolecules from gas dispersed in crude oil and propylene through complex chemical reactions such as polymerization and catalysis. In essence, it is to use the better components in crude oil to achieve the expected molecular morphology through chemical reaction and artificial control. Its molecules are arranged neatly, and its ability to resist external variables is naturally strong. Therefore, synthetic oil has a good constitution, and its ability to resist thermal stability, antioxidant reaction and viscosity change is naturally much stronger than that of mineral oil.
The fifth category, other synthetic oils.
Generally called lipids, there are diesters, polyol esters, polyethers, silicone oils, phosphate esters and so on. Chemical synthesis refined from animal and plant (biological) fatty acids and alcohols. Esters are inherently oily, and other base oils (including PAO) need additives to achieve this property. Moreover, the original polarity of esters can make oil film molecules adhere to the metal surface, so esters are the best in terms of lubrication performance.
So to sum up, lubricity: esters >; PAO & gtXHVI, MSDW, VHVI and other three types of base oils.
Ester oil is a kind of synthetic lubricating oil with good comprehensive performance and the earliest development and application. At present, almost all jet engine lubricants in the world are ester oils. The ester oil molecule contains ester functional group -coor'. According to the number and position of ester groups in the molecule, ester oil can be divided into diester, polyol ester and polyol ester.
1) has good viscosity-temperature characteristics. Ester oils have good viscosity-temperature characteristics and high viscosity index. Prolonging the main chain of ester molecules increases viscosity and viscosity index. When the main chain length is the same, the side chain viscosity is higher and the viscosity index is lower; For aryl side chains, the viscosity index is low. The viscosity indexes of sebacate and azelaic acid ester commonly used in diesters are above 150.
2) Good low temperature performance. The freezing point of diester with branched alcohol is usually low, and the freezing points of sebacate and azelaic acid ester are below -60℃, and the low temperature viscosity of the same type of ester increases with the increase of molecular weight. Incomplete esterification and the existence of some hydroxyl groups will obviously increase the low temperature viscosity of esters.
3) Good high temperature performance. The flash point and evaporation degree of lubricating oil affect the oil consumption, service life and safety in use, which is related to the molecular composition of oil. With the increase of relative molecular weight, the flash point of the same type of ester increases and the evaporation degree decreases.
4) Good oxidation stability. One of the advantages of ester oil is its strong antioxidant capacity, but it also varies with its structure. The oxidation stability of neopentyl polyol ester is better than that of diester. It is still necessary to add antioxidant and corrosion-resistant additives in practical use.
5) Good lubricity. Because of the polarity of ester groups in ester molecules, ester molecules are easily adsorbed on the friction surface to form an interfacial oil film, so the lubricity of ester oil is generally better than that of mineral oil with the same viscosity.
Application of ester oil
Ester oils are mainly used as aircraft turbine engine lubricating oil (also known as aviation turbine engine lubricating oil), followed by precision instrument oil, synthetic compressor oil, automobile engine oil, metalworking oil, synthetic lubricating ester base oil and applications in plastics, chemical fiber and fine chemicals.
Red line prompt: API SM/SL/SJ/SH/SG/CF is the best protection for gasoline and diesel engines. It is specially designed for supercharged engines. Excellent minimum friction coefficient, best oil film strength, best viscosity shear protection and excellent engine durability. The low temperature fluidity compatibility of crude oil and synthetic oil has a good effect on high or low mileage engines. It can't be used in brand-new engines-the mileage allowed is over 3000 miles. Redline high efficiency engine oil is a fully synthetic formula engine oil, which provides the highest protection effect by using the highest quality base oil and additives. It provides extremely high temperature stability by using alcohol ester base oil, which is the only lubricating oil that can lubricate modern aircraft engines. Its stability is higher than that based on mineral oil or other types of synthetic oil, which makes the engine cleaner and faster. Compared with most other synthetic engine oil, redline engine oil can reduce evaporation loss by 25-50% at the same viscosity. This function can provide better engine sealing performance, reduce fuel consumption and improve engine efficiency. At minus 40 degrees Fahrenheit, the flow rate of engine oil of redline0w40 is much higher than that of viscosity mineral oil of 0w30 (at minus 40 degrees Fahrenheit, the pumping speed of Red Line 0W40 is much faster than that of petroleum 0W30). Redline engine oil also has a higher natural viscosity index, which can provide better oil film bearing capacity for bearings and camshafts during operation compared with single-stage or composite-stage petroleum base oil. Compared with other oils, redline oil has unparalleled excellent thermal stability, oxidation resistance and lubricity to hot metals, which makes redline oil an excellent lubricant for supercharged engines and high compression ratio engines. High cleaning ability provides excellent engine cleaning and surface protection, even when the oil change interval is prolonged, and its cleaning ability exceeds that of any other synthetic engine oil. Redline also offers a 25% lower friction coefficient than most other synthetic engine oils and mineral oils, although it is designed for motorcycle wet clutches.

One more thing for beginners: there are many indicators of engine oil, such as SE, SF, SG, SJ, SL, SM! Just remember that the letter after S is in the order of ABCD, and the higher the grade, that is to say, the SM grade of the same brand engine oil is better than SL, and SL is better than SJ, and the words "10W40,20W50" are written on the engine oil bottle. The number before w represents the viscosity of the oil (the higher the number, the higher the viscosity, but the higher the viscosity is not necessarily good for the car). The number after W represents the stability of oil at high temperature (the higher the number, the better the stability). (refers to mineral oil. If it is fully synthetic, you can choose 0W40 or 5W50, 10W50 because of good heat dissipation. ) It is recommended to use 10W or 5W engine oil for long-distance running (if it is also used for short-distance running, it will increase engine wear). I like to pull high speed, because the engine temperature is high and the oil film is easy to break at high speed, so I can choose all synthetic engine oil (red line 5W50 is definitely the best).
