Engine oil Castrol or OEM Toyota

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

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.

Toyota oil is pretty good, actually. Lots of moly and a good additive package for overall protection.

As much as I love to use Mobil One, I am going to stick with Castrol because VW dealership won't give me any credit for the Castrol in exchange for the Mobil one.
