How much engine oil should the Envision take?
3 Answers
Envision requires approximately 5 liters of engine oil. Below are detailed explanations about engine oil: 1. Use the engine oil recommended in the owner's manual. Understanding the different quantities and grades on the oil packaging helps maintain smooth vehicle operation. 2. Learn how to read oil viscosity. Viscosity indicates the thickness of the fluid or its resistance to flow. High viscosity fluids are less likely to flow smoothly because they are thicker (for example, yogurt is more viscous than milk). Engine oil viscosity is represented by two numbers combined, such as 10W-30 or 20W-50. The first number, W, refers to the oil's temperature performance in winter. This clearly indicates how the oil flows in cold weather when it's cold. The second number shows how well the oil maintains its thickness under heat. 3. Check the user manual for the necessary certifications required for the engine oil. This helps ensure the vehicle remains in good health during the warranty period. Each type of engine oil has several different certifications, from API to ILSAC, ensuring the oil used meets the standards set by the manufacturer. 4. Use synthetic oil for high-end vehicles or extreme conditions. Although more effective, synthetic oil is also more expensive than its conventional counterparts. 5. Do not mix different types of oil in older vehicles. If the car runs well on a single-weight oil (one viscosity grade), do not switch now. This could cause sludge and dirt buildup in the engine to break loose and cause problems.
My Envision 2.0T just had an oil change, and the technician said the standard is about 5.7 liters. However, it's impossible to completely drain all the old oil during the change, so adding close to 5.5 liters is sufficient. When changing the oil, keep an eye on the dipstick—the ideal level when the engine is cold is slightly above the middle mark. If you're doing it yourself, remember to buy two 4-liter containers. Last time I changed to full synthetic oil, I had half a container left, which I saved for topping up during the next service. Don’t follow some people who see the manual says 5.7 liters and pour exactly that much—overfilling can damage the catalytic converter, and oil entering the combustion chamber is even worse. The maintenance manual suggests checking the dipstick every 5,000 kilometers, a habit that can help detect oil consumption issues early.
I've seen many Envision owners ask this question at the 4S dealership. Actually, it depends on the specific model. The 1.5T engine takes about 4.5 liters, while the 2.0T version requires approximately 5.5 liters. However, the most reliable method is to keep checking the dipstick while filling. It's safer to add the oil in three stages: first pour in 4 liters, start the engine and let it circulate for a few minutes, then turn it off and wait ten minutes to check the oil level before topping up to the middle mark on the dipstick. Once, a customer added 6 liters himself, which triggered the oil pressure warning light, and we had to spend quite some time draining the excess. I recommend using the manufacturer-recommended 5W-30 grade, especially for turbocharged engines. During maintenance, it's a good idea to have the mechanic check the valve cover gasket as well, since the older models are prone to oil leaks.
