Engine oil Castrol or Shell

I've topped off with Castrol Syntec 5/40. The cap says Castrol on it and the manual says to use VW approved synthetic 5/40 so I figure I can't do better than that.

Cost...$9 for filter online, $1/QT for Castrol GTX with rebate...so $15 or so...knowing that everythings done right..priceless!

You probably don't \"need\" syn, but its a darn good idea, esp if you want to run 5000k ocis with urban driving and/or want to keep the car for a long time. If you do stick, with conventional, which i don't recommend, make sure its better stuff like Castrol GTX.

I run either 0w40 castrol full syn or 0w40 pentosyn in all my cars. After changing oil every 1000miles for 5oil changes and ever 3k after that my old corolla looked like a brand new engine inside with 125k on it when I pulled the valve cover to do a t-belt.

I ended up buying the rotella t 5w40 stuff in the blue jug for like 16 bucks a gallon, my vr runs better and seams to like the stuff.

I am using Rotella T 5W 40 in my 1.6NA diesel and in my TDI. I have noticed no bad effects. The oil consumption is nil and there are no leaks, etc.

In my area, I always been able to find Shell Rotella T 5w40 synthetic motor oil. It's a Group III oil and is capable of 10K mile oil changes in the AHU/1Z/ALH TDI engines and should do fine for your TD.

I run Castrol's Syntec 5W 50 in my TD... it's CD and CF rated so fine for IDI TDs like yours... great in the extreme cold but thick enough for the summer.

I have used Rotella full synthetic 5w40 from day 1. No complaints. I work for an oil distribution company, and get to ask people questions that have been in the business before I was born. Eveyone of them says the same thing. Shell has forgotten more then the others will ever know.

My VW dealer uses Castrol Syntec 5W-40 that meets the VW 502 standard.
