Chery Arrizo 5 originally uses SM grade 10W-40 fully synthetic engine oil. If you want to change the engine oil during later maintenance, you can choose fully synthetic engine oils produced by brands such as Castrol, Mobil, and Shell. Recommended options include Chery Mobil Super SM5W30, Shell Helix Ultra 5w-30, Mobil 1, Mobil SN5w30, Valvoline SynPower GF-5 5W30, and Shell Penzzoil CP8-SN-5w30. The Chery Arrizo 5 maintenance manual recommends fully synthetic 5W30 engine oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Chery Arrizo 5 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Loosen the oil drain plug with a wrench and use an oil pan to catch the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Remove the oil filter with a special wrench; Apply engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the filler port on the engine valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to ensure the engine oil level is within the standard range.
