Audi A4 oil use

“Wanted to get back to you! From my mountains of research on the Audi excessive-engine-oil-use issue, the problem is two fold. The engine has low tension piston rings (which is common with most vehicles today due to EPA regulations it appears), but mostly, a poor oil control ring design. This issue plagues thousands and thousands of Audi owners for these year models. Audi played with the ring’s design from 09-16 models. It turned out the oil control rings get clogged very easily with carbon. The drain back holes get clogged as well. It gets really, really dirty in the videos I’ve seen on YouTube. You can google pictures to see the design changes over time with the A4 engines. So once the issue starts, it creates a vicious cycle of more hard carbon deposits due to the inefficient combustion cycle of the oil that’s now left in the chamber. And the consumption just drives higher. I maintain the manufacturer spec of 5W-40 full synthetic and change oil every 5k miles. 10k is just too long in my opinion for anything!

I want to let you know today, that after 1 engine oil flush with Flushing Oil Concentrate and 3 full tanks of fuel using the FTC Decarbonizer, my oil consumption has dropped from 1 qt per 581 miles to 1 qt per 1080. That’s already a 50% reduction— it’s very promising! I am optimistic this will continue to reduce the consumption to close to factory conditions! Audi allows for 1 qt to burn every 1k miles (which is crazy), but my car is already back above Audi spec now from using the Engine Blowby Pack treatments!

My goal is to make it 5k miles to a quart, let’s see how far we can take this!! I’m always scoping the combustion chambers to see how the carbon burns off over time! Much thanks!! Will keep you posted on this journey. Very exciting.”
