The Eado uses 5W40 engine oil. The Eado is a compact sedan under the Changan Automobile brand, with body dimensions of 4620mm in length, 1820mm in width, and 1490mm in height, and a wheelbase of 2660mm. It is equipped with two efficient engines: a 1.6L naturally aspirated engine and a 1.5T turbocharged direct injection engine. The interior of the car adopts a common symmetrical design, with a dark upper and light lower color scheme typical of family sedans. The lines on the steering wheel resemble those on the grille, and the air conditioning control panel features a glossy finish with large, user-friendly buttons that are easy to operate and offer comprehensive functionality.

I've been driving my Eado for almost five years, always using 5W-30 full synthetic oil for maintenance, as recommended in the manual. Even in northern winters at -20°C, it starts right up, and the engine runs smoothly at highway speeds. Last year, I tried saving money by switching to 10W-40, but my fuel consumption immediately increased by more than half a liter, and acceleration felt sluggish. The 4S technician said turbocharged direct-injection engines must use SP-grade or higher oils, like Mobil 1 or Shell Helix Ultra. Once, I went over 8,000 km before an oil change, and the drained oil was pitch black. So, I’d advise turbocharged car owners to stick to 5,000 km oil changes—don’t skimp on oil costs and risk engine damage.

Choosing engine oil mainly depends on the owner's manual requirements. Most Yidong models require API SP grade 5W-30. The number before W represents low-temperature fluidity; 5W can still pump at -30°C, making it particularly suitable for northern regions. The high-temperature viscosity of 30 provides protection for high-temperature components without being too fuel-consuming. The new Blue Core engines must use full synthetic oil, while the older naturally aspirated models can use semi-synthetic. Last time, when helping a neighbor inspect his second-hand Yidong, we found the previous owner had used mineral oil improperly, leaving sludge all over the valve cover. It's recommended to buy domestic brands like Gan series on JD.com's self-operated store—authentic and cost-effective. Never buy oil of unknown origin from roadside stalls.

Just finished researching the Yidong engine oil. The key points are threefold: first, check the viscosity and stick to 5W-30; second, choose fully synthetic oil with SP/GF-6a certification; third, pick reputable brands and don’t go for cheap options. 4S shops often use Shell HX8, but for self-, I recommend Mobil 1 Silver for better cleaning performance. A friend who drives for ride-hailing uses Longpan 9000, and it’s been reliable for 20,000 km. Important reminder: turbocharged models must use fully synthetic oil! One owner mistakenly used semi-synthetic, causing turbo bearing coking and a 4,000+ RMB repair. When changing oil, replace the oil filter as well—don’t skimp on the 20 RMB Bosch or Mahle filters.

Learned the hard way when changing oil for my 2015 Eado at home: Semi-synthetic is sufficient for the older 1.6L naturally aspirated engine, but post-2018 1.4T models require full synthetic. Last winter, using the wrong 5W-40 viscosity made the engine roar like a tractor for half a minute during cold starts. Later, switching to Castrol Edge 5W-30 as per the manual reduced fuel consumption from 8.1L to 7.3L. Observing the dipstick with different oils, mineral oil turns black after 3,000 km, while full synthetic remains clear even at 5,000 km. Now I bring six liters of oil for , as the 1.4T engine needs about 5.2 liters—remember to pair a four-liter pack with a one-liter pack.

The engine oil choice depends on the car model and year. For a 2016 Yidong XT, semi-synthetic Blue Shell is sufficient, but the Blue Whale version requires full synthetic oil with C5 certification and low ash content. I've compared Mobil and Idemitsu, both 5W-30. Mobil offers better acceleration, while Idemitsu provides superior cold start protection. A repair shop owner shared some tips: choose Shell for strong cleaning performance if often stuck in traffic, Mobil for high-rev driving, and consider Kunlun KR9 for budget-conscious owners. Important reminder: gravity oil change only replaces about four liters; for a thorough change, an oil extractor is needed. Also, check oil consumption before long summer trips, as direct injection engines tend to consume a small amount of oil.
