I use Royal Purple 5w40 and 5w30 HPS for 10,000 miles in my Audi A6 albeit a different engine. Works well and spotless.

Just lower the oci to 500 mile less then when you begin seeing oil consumption.if you want to keep 10000 oci?I would use 0% ethanol gas.this should lessen the oil consumption issue .(probably more like fix it if the seal are still sealing properly

The 1.8t turbo motor requires a robust ACEA A3 oil. I used GC, German-made Castrol 0w30, in my 2.7t for 100K mi with excellent results. The GC is close to a 40 wt. M1 0w40 is my second choice.

I always used a German-made Mann filter, available in the USA. I bought them online from an Audi dealer. Other filters may work, but for the price of a cup or two of oil one can get the exact fitment.

That castrol synteq 0w-30 has got to be a great choice.

You can do better than the Mann oil filter. See the discussion at http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/3453699/1

10,000 miles is pretty long for this motor. Check for sludge and consider a UOA if you're running it that long.



This.

Aren't the 1.8T known for sludge issues? I'd use a quality synthetic and keep it to a 5k mile OCI. Unfortunately it doubles your cost compared to doing a 10k OCI, but the two oil changes still cost less than the $100 it was previously costing for each oil change.



Only the longitudinal 1.8T's have the sludge issues.

transverse 1.8T's (Golf, GTI, Jetta & TT) have a larger crankcase capacity.

The 2005 Audi A4 uses a longitudinal engine.

Use a premium filter, but you don't have to have a German-made filter. Some of the premium Wix and Fram filters have fully synthetic media and are built to high standards.

If you wait for Autozone or Advance to have a "Buy 5qt get a filter" sale, you usually get a premium filter when you buy synthetic. You can get M1 0w40 at both stores, you can get German Castrol 0w30 or Castrol 5w40, and at Advance you can get Castrol 0w40.
