What is the difference between Shell engine oil HX3 and HX5?
2 Answers
Shell HX3 and HX5 mainly differ in that the higher the number, the higher the grade. Introduction to engine oil: Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, and shock absorption for the engine. Precautions for using engine oil: The selection of engine oil should be based on the requirements of the engine, choosing oil that matches the engine. Multi-grade oil is recommended as it offers advantages such as fuel economy, long service life, and high efficiency, providing better protection for the engine. The oil level should be slightly below the mark on the dipstick and not overfilled.
In my years of driving experience, the difference between HX3 and HX5 is quite noticeable. HX3 is a mineral oil-based engine oil, affordable and practical, suitable for older cars or daily commuting, such as short city drives, providing basic protection. HX5 upgrades to a semi-synthetic or fully synthetic level, featuring better anti-oxidation and cleaning components, which can reduce engine wear, especially performing more stably under high temperatures and high speeds. I’ve also noticed that HX5 has better viscosity control, potentially extending the oil change interval by several thousand kilometers compared to HX3, offering more durable protection for your car. If you drive a new car or frequently travel long distances, I would highly recommend HX5 because its overall performance is significantly improved, offering great value for money—don’t just focus on the price and overlook this. In short, considering your engine requirements and driving habits is key when choosing engine oil.
