Owner reviews for engine oil

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.

I rebuilt a 1.6TD, my first rebuild about 16 years ago, and it had Mobil 1 15w50 since day one. I sold the car with 550,000 miles on the engine and it was still purring.

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 use the Elf Excellium DID 505.01-spec 5W40 in my non pd-tdi. no problems either.

Used the rotella for the first 90,000. Switched to AMSOIL so I can change the oil half as often. I'm good with either one. The car has 146,000 and runs as strong as ever.

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.

Run Mobil 1 and you need nothing else. I change the oil every 10K, at 150K still going as strong as ever.

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

FWIW, I used Amsoil in my old Mk4 GTI VR6 and in my R32 with no issues.
