Can Non-Certified Engine Oil Be Used in Volkswagen Cars?
1 Answers
Volkswagen cars cannot use non-certified engine oil, as it will shorten the engine's lifespan. Engine oil for Volkswagen cars: Volkswagen cars are typical representatives of German vehicles. All Volkswagen engines, including the more common 1.4T, 1.8T, 2.0T, 1.6L, and 2.0L, have exceptionally strict requirements for the HTHS (High-Temperature High-Shear) index of engine oil: the HTHS value must be greater than 3.5. HTHS represents the oil film strength under high-temperature and high-shear conditions, reflecting the lubricant's ability to maintain lubrication under such engine operating conditions. Important Notes: Almost all 40-viscosity engine oils meet the HTHS > 3.5 requirement. Additionally, high-viscosity 40-grade oil can form a sufficiently thick and strong oil film to protect Volkswagen and other European engines.
