Should the Mistra use 5W30 or 5W20?
2 Answers
Mistra uses 5W20. 5W20 engine oil is a multi-grade engine oil, where 'W' stands for winter, the number before 'W' indicates the low-temperature resistance index, and the number after 'W' represents the viscosity index of the engine oil. Engine oil is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Taking the Mistra 2021 1.8L CVT GLX Elite Edition as an example: its length, width, and height are 4780mm, 1815mm, and 1460mm respectively, with a wheelbase of 2770mm, a top speed of 202 km/h, and equipped with a CVT continuously variable transmission.
I've always driven a Hyundai Mistra, and the manual recommends using either 5W-20 or 5W-30, depending on how you use the car. Personally, I use 5W-20 in northern winters for quicker starts and better fuel efficiency, and switch to 5W-30 during summer road trips for more stable engine protection. The Mistra handles daily driving just fine, but don’t randomly switch oil grades—it can wear out parts and lead to costly repairs. I suggest checking your car’s manual first; it usually specifies climate-based recommendations. I make it a habit to check the oil condition every 5,000 km—oil that’s too thin or too thick can affect performance, especially since 5W-20 offers slightly weaker protection under high temperatures. Remember, regular maintenance is more important than obsessing over which oil to choose.
