What type of engine oil is suitable for the Vios?
2 Answers
The Vios is suitable for engine oil with a viscosity of 5w30, requiring approximately 4 liters. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Taking the 2021 Vios as an example, its body dimensions are: length 4435mm, width 1700mm, height 1490mm, with a wheelbase of 2550mm and a minimum ground clearance of 160mm. The 2021 Vios is equipped with a 1.5L naturally aspirated engine, delivering a maximum power of 81kW and a maximum torque of 138Nm, paired with a 5-speed manual transmission.
As a daily commuter driving a Vios, I've always believed that regular oil changes are crucial. The owner's manual recommends 5W-30 viscosity since the Vios has a small engine - using oil that's too thick or thin could cause damage. I always opt for full synthetic oils like Mobil 1 or Toyota's genuine oil, which cost slightly more than semi-synthetics but perform better, providing quicker cold starts in winter and better fuel efficiency. My oil change interval follows mileage - I stick to every six months or 8,000 km to prevent sludge buildup that could cause abnormal engine noises. When selecting oil, always check the API rating first - higher grades like SN or SP offer better protection. I learned this the hard way when using wrong viscosity caused my fuel consumption to spike. Regular oil changes can extend engine life by at least five years.
