What is the oil specification for the Cruze?
2 Answers
Chevrolet Cruze uses 5W30 full synthetic oil. The number 5 represents the oil's low-temperature resistance, with smaller numbers indicating lower low-temperature resistance. The number 30 represents the oil's high-temperature resistance, with higher numbers indicating better high-temperature resistance. The W stands for winter use, eliminating the need to change oil between seasons. Explanation of oil specifications: 10W-40 is its SAE standard viscosity value. This viscosity value first indicates that the oil is multi-grade. W stands for WINTER, and the number before W represents the oil's flow performance at low temperatures, with smaller numbers indicating better cold-start performance. The number after W represents the oil's stability at high temperatures (i.e., the likelihood of thinning), with larger numbers indicating better high-temperature stability. Recommended oil for different vehicle models: Different manufacturers have varying engine technical requirements and different viscosity requirements for oil. Japanese and Korean models recommend using oil with viscosity values of 20 or 30, such as SAE 0W-20 or 5W-30. American models recommend using oil with a viscosity value of 30, such as SAE 5W-30. European models recommend using oil with a viscosity value of 40, such as SAE 5W-40. If owners are unsure, they can directly refer to the recommended oil specifications in the maintenance manual.
As a Cruze owner, I researched engine oil when I first started using the car. I remember the manual recommending 5W-30 synthetic oil, especially those with dexos1 certification. This viscosity grade is crucial for engine protection. In cold winter temperatures, the 5W indicates good fluidity for faster starts; in summer heat, the 30 viscosity maintains stability with less wear. This grade generally suits different engines like 1.4T or 1.6L. Never use higher viscosity oils like 10W-40 by mistake, as it would increase fuel consumption and require shortening the oil change interval to 3,000 km. Regular changes every 5,000 km can extend vehicle lifespan, and choosing full synthetic oil makes maintenance easier. New owners must check their manual - don't compromise safety by arbitrarily switching oils to save money. Safe driving comes first.
