Does the Audi Q3 1.4T Burn Engine Oil?
2 Answers
Under normal circumstances, the Audi Q3 1.4T does not burn engine oil. Here is additional information: 1. Burning Engine Oil: Burning engine oil refers to the situation where oil enters the engine's combustion chamber and participates in combustion along with the air-fuel mixture. If a vehicle exhibits oil burning, it can lead to premature failure of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, increased fuel consumption, and excessive exhaust emissions. In severe cases, insufficient engine lubrication can cause irreparable damage to the engine or even render it unusable, significantly increasing repair costs and posing potential safety hazards. 2. Causes of Oil Burning: Domestic fuel quality (including gasoline and engine oil) tends to produce carbon deposits; carbon deposits can cause the piston rings to stick, losing their oil-scraping function; clogged oil return passages prevent oil from returning to the crankcase normally; excessive wear between the cylinder walls and pistons, leading to excessive clearance; and corrosion or aging of valve seals and crankshaft seals, resulting in oil leakage.
I've driven an Audi Q3 1.4T for three years, and honestly, I haven't encountered any serious oil burning issues with this engine. During maintenance in the first two years of ownership, checking the dipstick showed virtually no oil level change. Later, as I started taking more long-distance trips, even now at over 60,000 kilometers, it only requires topping up half a liter every 5,000 kilometers at most. Compared to the previous generation Q5, it's indeed much better - the EA211 engine is generally reliable overall. However, there are two points to note: first, I use full synthetic oil and maintain it diligently; second, during cold starts in northern winters, the exhaust emits a slight blue smoke, but it returns to normal after the engine warms up. Generally speaking, it performs better than expected, but as the car ages, piston ring sealing will inevitably degrade, leading to slightly higher oil consumption.
