Losing oil, no visible leaks

[nectarguru]

147k on the clock. Just before my past two oil changes my Check Oil warning popped up. I made a note to the dealer to check for leaks, which they found none. It's only been a few thousand miles since my last oil change but just yesterday my oil light came on again. On a cold engine my levels are just under half on the dip stick. Any ideas why I might be losing oil? Also, I've never had to put oil in my car before. Which commonly available oil can I top off in my MK7?

Anything 507 rated. Any VW dealer will have some and some are also available from NAPA and others. I bought this from them on sale a ways back. 4 cases.

I always lose right at 1 liter per 10k miles. @100k miles now, but it's been that way since purchase and have had two different turbos on the car with still the exact same results.
FWIW, my '01 does the exact same, 1 liter per 10k and it's at 313k now and fairly healthy mods.

@adjat84th That new engine in yet, I didn't see any updates in the thread , or TDI club is just not giving me notifications, which does happen quite often, haha.

Not too sure about these new cars with new emissions stuff.. but for kicks, stick your finger in the tailpipe. It should be very dry soot. I've found on my older cars, leaky turbo seal creates a pasty black soot, like somewhat moist

Nothing to update just yet..lots of other things going on in life but my goal is to be done this year with it

There is more than one thread here discussion the CRUA and CVCA (which for us is 2015 only) TDIs using some oil. I think it is just a characteristic of this particular engine, not sure why. The maximum allowable limit is such that you'd easily empty the crankcase between services (and many VAG gassers can do just that!).

I'd just check and top the oil regularly as needed. It's like a Subaru except faster and with better fuel consumption!

if you start off with the oil in the middle of the hash marks and try and go 10k you may end up with a low oil light, if you start oil level off at the top of the hash marks you should be fine.

Least that's the experience on our end. Also I've started using copper crush washers on the drain plug as the OEM steel washers was ever so slightly weaping.
