What type of oil does the Mazda 6 use as factory standard?

[FrankLynn]

Mazda 6 uses 5w30 engine oil as factory standard. The 'w' stands for winter, indicating its use in winter conditions. The number '5' before the 'w' represents the viscosity at low temperatures, with a smaller number indicating better fluidity and cold resistance. The '30' after the 'w' refers to the viscosity at 100 degrees, with a higher number indicating greater viscosity and better high-temperature resistance. The Mazda 6 is a mid-to-high-end sedan introduced by Mazda, with dimensions of 4670mm in length, 1780mm in width, and 1435mm in height, and a wheelbase of 2675mm. The Mazda 6 is equipped with two engines: a 2.0-liter and a 2.3-liter inline four-cylinder engine.
