Even though oil changes are pretty much the most basic jobs required for a car's maintenance, it's worth a blog post to discuss the oil used by Aston Martin. There are plenty of questions regarding what to use, where to get it, why it costs so much... Hopefully this blog post will help explain things a bit and clear up any confusion.
An air-oil separator (AOS) is a small component connected to the engine that, as the name suggests, separates oil vapors from the air that passes through it. Aston Martins have these and they work... in theory. In this blog post I'll be talking about the failings of the OEM air-oil separator, a common leaking problem, and how to fix both.
