Engine oil LIQUI MOLY or Castrol

My 2012 Golf TDI with the DPF stuff states that it **MUST** have 507 00 5W30 spec diesel oil, not 505 00 or anything else.

FWIW: I live in Maryland and use Castrol Syntec 5w-40 in my 2012 JSW 2.5. I usually buy the filter and plug/washer from the dealer because they have the best price and I don't have to wait or pay for shipping.

E92 Changed the oil with Liquid Moly 5w40 and a Wix air filter and drove from Texas to Colorado. 39.2 MPG average!

I use castrol in my 2014 cx5.

Just got my first Blackstone oil report on this engine. LiquiMoly 5W/40, 9,098 Miles. Here' s their comment: "We think you've got the oil change interval dialed in pretty well, but with results like these, you could push it a little if you wanted or needed to.

I use Castrol Edge European Formula 0W40 for all of my VWs (2005 Phaeton, 2014 CC 3.6, 2017 Jetta SE and now a brand new 2019 Alltrack SE): I buy it from Amazon, for $ 24.47 for 5 qts. The oil has a "European Formula" label on the front and specifically states "VW 505. 00 and 502. 00 " on the back, and is made in Brussels, Belgium.

I have used the LiquiMoly kit and it seems great. Awaiting my Blackstone oil analysis from the first oil I put in...ran it for 9000 miles, which was more than I had intended.

I got some Castrol Edge Titanium FST 0W40 which is VW502 00 approved. I decided to try this oil as their name is on the oil filler cap, as in the past with other cars I always used Mobil 1 0W40.

Switched over to LiquiMoly Molygen since 90K. Engine and transmission drives like new.

Castrol Edge European formula 5W-30. Closest thing to group IV you can easily find in the states.
