Does the EA839 engine burn oil?
2 Answers
EA839 engine does not burn oil. Relevant information is as follows: Introduction: The power parameters of the 2.9T version of the EA839 are a maximum power of 450 horsepower and a peak torque of 600 Nm. In terms of performance, it is more aggressive than the 3.0T version's 340 horsepower and 500 Nm. A very important reason is the advantage of the HOTV turbo layout, which allows the 2.9T engine to easily be equipped with a twin-turbo system, directly distinguishing it from the single-turbo twin-scroll design of the 3.0T version. Models applied: Audi's A8 (D5), Q7, Q8, A6, S4, and other models have used this engine. Later, the engine codes for Audi's RS4 and RS5, as well as Porsche's Cayenne S, Panamera, Macan-GTS, and other models, are also EA839.
I've been driving an Audi S4 with the EA839 engine for over two years. Initially, the oil consumption seemed normal, but after driving more than 10,000 kilometers, I noticed a significant drop of half a liter every 800 kilometers. Upon inspection, it turned out that the piston rings were slightly worn, causing severe oil burning. The mechanic mentioned that such engines have high turbocharger pressure and piston designs prone to issues. Now, I've developed a habit of checking the dipstick every two weeks to ensure the oil level is within the normal range, and I've switched to full synthetic oil to reduce wear. Don't ignore blue smoke or unusual smells—addressing problems early saves both hassle and money. Delaying repairs might damage the engine. Regular maintenance is crucial, and don't skimp on oil quality by choosing cheap products. Overall, not all EA839 engines burn oil, but the incidence rate is high.
