Which is better, Total 9000 or Shell Helix Ultra?
1 Answers
Both Total Quartz 9000 and Shell Helix Ultra are good engine oils, each with its own advantages. Below is the relevant introduction: Engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10 (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'blood' of a car. Lubricant additives: Additives are the essence of modern high-grade lubricants. Proper selection and addition can improve their physical and chemical properties, endow lubricants with new special characteristics, or enhance their existing properties to meet higher demands. Carefully selecting, balancing, and reasonably blending additives based on the required quality and performance of the lubricant is key to ensuring the quality of the lubricant.
