How many liters of engine oil are suitable for the Q5?
1 Answers
Q5 engine oil filling capacity is 4.5 liters. Here is the relevant introduction: 1. Engine oil is extremely important for engine operation as it serves two major functions: lubrication and heat dissipation. Therefore, the engine must never run low on oil at any time. However, overfilling (exceeding the upper limit on the dipstick) can have adverse effects. Excessive oil increases the rotational resistance of the crankshaft, reduces engine output power, and may cause oil to enter the combustion chamber, leading to oil burning, blue smoke emission, and increased fuel consumption. 2. The residue from burned oil (primarily composed of carbon, which is very hard) can accumulate on the combustion chamber walls, reducing the chamber's volume and thus lowering the engine's compression ratio. Additionally, it accelerates wear on the cylinders and pistons, shortening the vehicle's lifespan.
