Engine oil Castrol or OEM Volkswagen

As an aside, all the oil used to be Castrol and has now transitioned to a VW boxed product produced by Mobil 1. THAT is the correct oil.

I've switched to Castrol Magnatec 10W-40 which seem to do better wrt oil pressure.

Try using 5w30 castrol from walmart black container with green writing, since switched been driving 2.7k with in 2-3 month oil on the same level

Its not uncommon for a new Tiguan to use oil. The new oil is really thin. It is VW special,you might as well go to the dealer and purchase a quart.

I'm running 5qt 5W40 full synthetic oil (Castrol Edge, to be specific). The oil is changed yearly cause I never get close to the 10k miles suggested by VW for an oil interval.

Went to the dealer today and got this. 5 QTS CASTROL EDGE PROFESSIONAL 0W20 LONG LIFE IV (RED CAP) 1 VW Oil filter, Volkswagen 04E 115 561 H 1 Drain plug with washer $74.99

I ran Castrol 0w-40 euro blend for both my e46s and the stuff was awesome

I did an oil change at 6,300 miles on the factory fill. I sent it in for a UOA through Blackstone labs, but I'm not sure how to attach it here. The TBN showed some life still left in the oil, they suggested trying 8,000 miles next.

I would drain that oil with the Marvel in it and use use 0w-40 Castrol Full Synthetic (Made in Germany/Belgium). You can get a 5 quart jug at Wal-Mart for less than $25 usually. It's probably the best "over the counter" oil you can use in a VR6. Widely used and highly recommended.

I've used mobil 1 20-50 for the last three oil changes and had really bad ticking noise from the head. This last oil change I used casterol GTX and have had a lot less ticking since. I'm no longer sold on mobil 1 for the rocco.
