Engine oil Mobil or OEM Audi

I use Mobil 1 synthetic blend HIGH MILAGE 5w-30. I think the high milage formula is the best for these old engines.

My G37x likes mobil 0w 30 car feels great with this oil

Been using Mobil1 5W-30 since 1998... GTI now has 232,500 miles and is smooth as silk. I do oil changes on the dot at 5K miles.

The part number they listed for each quart of oil was G-E55-540-1B-DSP . Look that up and you'll see why oil changes are expensive. Somehow I don't think the oil is better than the Mobil1 I buy at Walmart at $24 for 5 quarts.....

Mobil1 should be fine. People are anal about oil but I've got 90k on my wrx with regular oil changes every 3-4k miles with Pennzoil ultra platinum or Mobil1 Extended Performance.

Edge Professional 508 is excellent, however, I have to agree with @VWmechatronic , the Mobil 1 sourced stuff is top notch. Almost 5K on mine and level on dipstick has not moved.

I use Mobil ESP VW507.00 5w30, which is on the approved oil list and I buy for $30 when it goes on sale at Canadian Tire.

I put Mobil 1 4 Stroke Synthetic into my Ninja 250. Honestly, any reputable brand 10W-40 oil will do if you change it routinely.

If you on a budget, Mobil 1 oil is great. If you want the best, Look up AMS oil. Expensive but worth it.

Yes, you can certainly use 506.01 in your TDI and it's used in many TDIs around the world. However, based upon some of the UOAs offered up, I'd suggest moving to 507.00. The 506.01 has shown relatively high wear metals.
