Should the New Vision use 30 or 40 engine oil?

It is more appropriate to use 40 engine oil for the New Vision, but the specific choice depends on individual circumstances. Introduction to engine oil: Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, and shock absorption. Precautions for using engine oil: The selection of engine oil should be based on the requirements of the engine, ensuring compatibility. Multi-grade oil is recommended due to its advantages in fuel efficiency, longevity, and effectiveness, providing better protection for the engine. The oil level should be slightly below the mark on the dipstick, avoiding overfilling.

I've been driving the new Vision for a while now, and I find that 30 viscosity oil works best. The manual also recommends 5W-30, which ensures quick starts and fuel efficiency. For my daily city driving where temperatures aren't too high, using 30 viscosity oil keeps the engine running smoothly without any issues. If the car is older or frequently driven in high-temperature areas, 40 viscosity oil can provide better protection, but beginners should avoid switching arbitrarily. Remember to change the oil regularly, about every 5,000 kilometers, and check the oil level to keep it clean. Don't buy overly cheap oil; stick to reliable brands to avoid engine damage. In short, just follow the manual and choose 30 viscosity—no need for unnecessary tinkering.

As a car enthusiast, I believe engine oil viscosity depends on engine requirements and environment. The factory-recommended viscosity for the New Vision is 30, which is thinner with better fluidity, saving fuel and being eco-friendly. But if you drive aggressively or face high summer temperatures in the south, a thicker 40 viscosity offers better wear protection. I've tested different oils - 30 is sufficient under moderate conditions, but don't overlook specifications like the '5W' prefix indicating cold-weather fluidity. For oil changes, I recommend authorized shops as regular maintenance is key. If engine noise increases, the viscosity might be unsuitable - always check the manual before deciding.

Hey, I'm a young car owner. The New Vision runs great with 30-viscosity oil as recommended in the manual – the engine responds quickly and stays quiet. Don't risk switching to 40 unless your car is older or often driven in high temperatures. Always remind the technician to check for leaks or dirt during oil changes. Keep it simple with standard oil for peace of mind, cost savings, and safety first.

After years of driving, I believe the New Vision performs best with 30-viscosity oil. The manual clearly states that 30-grade oil ensures quick starts and lower fuel consumption under stable daily temperature conditions. For frequent long-distance driving or operation in high-temperature summer regions, consider upgrading to 40-grade oil for enhanced protection, though at slightly higher cost with oil change intervals around 5,000 km - don't extend beyond this. Always choose certified oil products and avoid mixing different brands. Proper maintenance prevents engine failures - never cut corners on critical components.

From an economic perspective, I recommend using 30-viscosity oil for the New Vision as it is more cost-effective and environmentally friendly. The original factory design uses 30-viscosity oil for better flow, fuel efficiency, and reduced emissions, making the car run smoothly. If you frequently drive under heavy loads or have an older vehicle, 40-viscosity oil provides an extra layer of protection but slightly increases fuel consumption. Don’t underestimate the impact of oil on engine lifespan. Follow the manual for oil changes and adjust according to the season for optimal reliability.
