What is the difference between Shell HX8 and Gray Shell?
3 Answers
These two types of engine oils have different base oils, resulting in differences in lubrication performance, service life, and price. Below is a relevant introduction to engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), 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. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and improve any shortcomings in the base oil's performance, imparting new characteristics. Additives are an essential part of engine oil.
I've been running an auto repair shop for twenty years, and car owners often ask about the difference between HX8 and Helix. Simply put, HX8 is Shell's semi-synthetic motor oil, affordable and suitable for daily family cars or older vehicle maintenance. Helix refers to the Helix Ultra series, which is fully synthetic, offering better performance, superior engine protection during high RPM or cold starts, and higher durability. The two differ in base oils, with Helix containing more anti-wear additives to reduce noise and wear. If you're commuting in the city, HX8 is sufficient; for long-distance driving or high-speed runs, Helix is more reliable. Remember, regular oil changes are more important than oil selection—don't skimp and risk damaging your car.
As a car enthusiast, I've compared HX8 and Shell Helix Ultra multiple times. For regular commuting, HX8 is more economical, but Shell Helix Ultra performs better at high speeds or in low temperatures: it flows faster, prevents engine shaking during cold starts in winter, and reduces noise. In terms of durability, Shell Helix Ultra claims to last longer, extending the oil change interval by several thousand kilometers and providing better protection for engine components. Although Shell Helix Ultra is more expensive, it's more cost-effective in the long run. I'd recommend Shell Helix Ultra for new cars or those seeking a smoother driving experience, while HX8 is suitable for older vehicles. I also pay attention to API standards, and Shell Helix Ultra has a higher rating.
