Recommended Engine Oil Type for Changan UNI-T

Using the correct oil type is absolutely essential for protecting your Changan UNI-T's engine and maintaining peak performance. Here are the detailed specifications you need to know:

Oil Type:

Your UNI-T requires fully synthetic engine oil for optimal protection and longevity. Synthetic oils provide better performance in extreme temperatures and longer service intervals compared to conventional oils.

Viscosity Grades:

Temperate climates (most regions): 5W-30 is the ideal viscosity
Hot climates (consistently above 30°C/86°F): Switch to 5W-40 for better high-temperature protection
Cold climates (regularly below -15°C/5°F): Use 0W-30 for easier cold starts

Quality Standards:

Look for oils meeting API SN/SP or higher specifications and ACEA A3/B4 standards. These certifications ensure the oil meets the strict requirements of modern turbocharged engines like the UNI-T's.

Oil Capacity:

When performing a complete oil change with filter replacement, your UNI-T's engine takes approximately 4.5 liters of oil. Always check the dipstick after refilling to ensure proper oil level.
