Fully synthetic engine oil brands include Mobil, Castrol, Shell, Liqui Moly, Fuchs, Motul, Amsoil, HKS, Great Wall, and Tongyi. Below is more information about fully synthetic engine oil: Introduction to synthetic engine oil: Fully synthetic engine oil is a type of oil manufactured by humans using chemical synthesis methods. It is an artificially produced oil that involves chemically decomposing various natural substances during the manufacturing process, then synthesizing them with other substances to finally produce fully synthetic engine oil. Advantages of synthetic engine oil: Fully synthetic engine oil offers higher lubricity than mineral oil, lower friction resistance, resistance to oxidation, and strong detergency. It is less prone to deterioration, has lower evaporation loss, and a longer lifespan compared to conventional oil. It exhibits excellent chemical stability, good radiation resistance, high oil film strength, minimal foaming, superior lubrication, and reduced wear. Additionally, fully synthetic oil has minimal thermal degradation, saves fuel, and provides better engine protection.

There are many brands of fully synthetic engine oils on the market, and I have used and researched quite a few. Mobil 1 is a veteran powerhouse, widely recognized by many car owners for its quick cold starts and strong performance. Shell Helix Ultra series excels in cleaning capabilities, resulting in quieter engine operation. Castrol Edge is heavily advertised, focusing on cold start protection, making it particularly suitable for northern regions. Total Quartz 9000 offers great value for money with balanced performance that rivals big brands. There are also niche but well-regarded options like Motul 300V, which specializes in racing oils with excellent high-temperature resistance, and Amsoil's Signature Series that can extend oil change intervals up to 20,000 kilometers. When choosing engine oil, don't just look at the brand—first check your car's manual for the correct viscosity, then consider road conditions and budget, and always buy from reputable sources to avoid cheap imitations.

I usually prioritize cost-effectiveness when maintaining my car and have tried five or six different brands of full synthetic oil. Mobil, Shell, and Castrol are considered the 'big three'—slightly more expensive but with stable quality. Total and Chevron are about half the price and perfectly adequate for daily driving. Germany's LIQUI MOLY has unique additive formulas that clean carbon deposits, making it ideal for older models. Nowadays, domestic brands like LongPan full synthetic oil have also gained traction, with promotional prices under 200 yuan per barrel—easy on the wallet. I recommend changing the oil every 8,000 kilometers; don't blindly trust expensive brands—any oil from reputable manufacturers won't harm the engine. Remember to replace the oil filter at the same time and keep maintenance records for better resale value.

Fully synthetic motor oil brands can be categorized into several types: basic models like Mobil and Shell are suitable for family cars; performance-oriented options such as Motul 8100 or Red Line offer strong high-RPM protection; for extended drain intervals, choose Amsoil, which can easily last 20,000 kilometers. Niche brands like HKS are tuned for racing and are commonly used by car modifiers. When purchasing oil, pay attention to the API SP rating and ACEA standards on the bottle—Volkswagen and Audi require 504/507 certification, while BMW recognizes Longlife-01. Select the right viscosity for different seasons: 5W-30 is suitable year-round, while 0W-20 saves fuel but offers weaker high-RPM protection. Remember to change the oil annually in March or April to avoid the humidity of the rainy season.
