Engine oil Mobil or ZIC

At around 60k the car really began consuming oil (1qt every 2000 miles or so). I used to use regular 5w-30 oil, and then switched to Pennzoil full synthetic 5w-30, which didn't help the problem at all, and maybe even made it worse. Finally, i switched to Mobil 1 0w-40 and all consumption has basically come to an end. I've not had to put a drop in it after 1500 miles and its at the same level as the last oil change.

i also switched to the mobile 1 0w-40 and dont burn any in my 2.0t

Mobil 1 0W-40 is what I use; had 0 oil consumption problems w/ stock pcv.

Of course this is assuming you're using really good oil, something like Mobil1 ESP 5W-30 or at least the Castrol LL03 VW507.

My TDI is now at 5000 miles, and per my personal preference I changed the oil. It is very simple with an oil extractor. Start to finish will take less than 20 minutes. This is a fast and simple way to change the oil and stay clean.

I have been using Mobil 1 Truck and Suv, and I picked up a few mpg's which is what I recommend.

I use Mobil 1 Turbo Diesel Truck 5w-40. A 5w-40 full synthetic is going to work brilliantly in your climate.

Have also used M1 TDT 5w40 and have had great success

I was using 1 quart every 1000 miles on my o6 2.0t GTI, I actual changed to 5w40 Mobil Turbo Diesel and have gone down to about 1 quart in about 2200 miles also check you pcv as they are notorious for going bad.

IMO M1 0w40 is a very good oil that may do well in many cars. It is a master at being built to meet manufacturers specs.
