New2Tregs any update on your oil loss ?
Our 2011 has all of a sudden, last 6 months, started to need oil added between changes. We have had the Treg since 44K and now at 109K, never went below the second from last tick on the electronic meter between changes and now I'm adding 1/3 quart every 1,000 miles to top off.
About 6 weeks ago I noticed it had dropped a couple of ticks, monitored it and stayed constant and then all of a sudden down a couple more ticks.
My wife drove from Rochester, NY to Columbus last weekend so I topped off before she left, checked both electronically and with dip stick, and when she got back yesterday it was down 4 ticks. this is only a roughly 720 miles RT.
With this type of oil loss I would expect if it was being burned through the engine I could get a black soot off the exhaust tips just by touching with my finger and even though there is a light carbo on outer edge it does not transfer to my finger.
My wife's commute is short and unfortunately I don't think in this colder weather the car fully warms up on any of the driving she does around our area and only on Fridays she goes longer distance, making the rounds checking out Marshalls/TJMaxx, and skiing on weekends so I am hoping we are not getting sludge buildup in the oil ring of the pistons causing oil to be left on the cylinder walls instead of flowing back through the tiny holes in piston behind oil ring like it is designed to do.
This is a big issue with early build 2.0T B8 A4 engines (09-11) that caused Audi to rebuild under warranty with new redesigned pistons/rings to correct.
First thing I am going to do is change oil change interval to 5/6K and use the Ravenol internal engine cleaner on next change. I have been using VW spec 5w40 oil since we have had the Treg and for last few years it has been Ravenol VMO 5w40 only.
These 5.6 VR6 engines have a very good reputation so I am concerned that all of a sudden it has needed the oil topped off regularly
