Should the Reiz use 0W20 or 5W30 engine oil?

[OAniyah]

The Reiz can use either 0W20 or 5W30 engine oil. 1. The choice of engine oil type depends on the following two scenarios: (1) For new vehicles, it is recommended to use 20-grade oil. (2) For older vehicles, it is recommended to use 30-grade oil. 2. Relevant knowledge about engine oil is as follows: (1) The number before W indicates the minimum temperature at which the oil can be used. ① 0W is -35℃ ② 5W is -30℃ ③ 10W is -25℃ ④ 15W is -20℃ ⑤ 20W is -15℃ (2) The number after W represents the kinematic viscosity of the oil at 100℃. A higher number indicates higher viscosity, better protection performance at high temperatures, and better stability at high temperatures. (3) The viscosity of engine oil for Japanese cars should not be too high. Most Japanese cars recommend using 20-grade oil. Generally, 30-grade oil is the highest used, except for the following three situations: ① Older vehicles ② Performance vehicles ③ Vehicles with oil burning issues
