Does the Audi Q7 Burn Engine Oil?
1 Answers
Audi Q7 does experience engine oil burning. Here are the reasons why the Audi Q7 burns engine oil: 1. To increase power, the engine cylinder walls have a honeycomb pattern designed to store more oil for enhanced lubrication. However, this honeycomb oil storage pattern has slightly weaker sealing, causing a small amount of oil to leak into the combustion chamber. 2. Audi, along with other German car brands, has engines with higher compression ratios compared to other car manufacturers. This results in higher engine operating temperatures, especially in turbocharged engines. If the engine oil has poor high-temperature stability, it can evaporate, accelerating oil consumption. 3. Congested road conditions in China combined with low-quality fuel lead to excessive carbon deposits. Additionally, German engines inherently have larger gaps between pistons and cylinder walls, and while the piston rings have good toughness, their tension is weaker. If the engine oil's cleaning ability is insufficient, carbon deposits on the pistons cannot be cleaned in time, increasing cylinder wall wear and reducing sealing performance, making oil burning inevitable.
