Should the Tiggo 3 use 5w30 or 5w40?

Tiggo 3 uses 5w40. Here are the detailed specifications about the Tiggo 3: Overview: The Tiggo 3 is positioned as the "Exemplar of Practical and Stylish SUV," a new-generation product developed under Chery's 2.0 strategy, following a forward R&D system, and undergoing 183 perfect evolutions across 12 major categories. It features a brand-new, high-quality, and stylish interior, along with authentic urban off-road SUV driving and control. Other specifications: The wheelbase is 2510mm. The vehicle dimensions are 4420mm × 1760mm × 1670mm. The trunk capacity is 550 liters. The fuel consumption ranges from 6.7L to 7.9L per 100km. The fuel tank capacity is 55 liters. The engine type is ACTECO-SQRE4G16. The top speed is 175km/h. The curb weight is 1358kg/1390kg.

As a mechanic with years of experience, I often help car owners choose engine oil. The Tiggo 3 manual typically recommends 5W30, especially for newer engines—lower viscosity means quicker starts and better fuel efficiency. 5W40 has higher viscosity and is suitable for older or worn-out vehicles, offering better leak prevention. However, the Tiggo 3's original engine is designed for 30-weight oil, so switching to 40 is only advisable for older cars or those frequently driven in hot climates. Remember, using the wrong oil can increase fuel consumption and engine strain, so sticking to the manual is best. Also, consider your driving habits: if you often haul loads or climb hills, higher viscosity can help. Check your climate—5W30 won’t freeze in cold northern winters, while 30-weight is sufficient for hot southern summers. In short, 5W30 is the safest choice for new cars, but consult your mechanic during maintenance for tailored advice.

I've been driving my Tiggo 3 for over three years and tried two types of oil. Initially, I used 5w30, which made the engine run smoothly with low fuel consumption, just as recommended in the manual. Later, I tried 5w40, which felt okay in summer but resulted in slower starts and increased noise in winter. The standard recommendation is 5w30, matching the engine's design viscosity for fuel efficiency and reliability. While 5w40 offers better protection, it's not cost-effective unless your engine is severely worn or you frequently drive in high-temperature environments. I stick with 30-grade oil, change it regularly, and haven't had any issues. Considering costs, 5w30 is cheaper and saves fuel money in the long run—don't switch lightly to avoid more harm than good. For mountainous terrain, thicker oil might be better, but for normal city driving, 30 is sufficient.

When I first bought the Tiggo 3, I also researched engine oil. The dealers all said that 5w30 is sufficient as it's the standard configuration with lower viscosity, faster starts, and better fuel efficiency. 5w40 is too thick, may increase fuel consumption and engine load, and should only be considered if the car is old and has abnormal noises. Always follow the manual—if it specifies 30, stick with it and don't change. After using it for a while, the engine runs smoothly with no issues. Temperature impact: 30 is fine for cold northern climates, and also suitable for hot southern regions.
