Best Engine oil for Volkswagen Jetta

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.

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

When I bought my (new) 2002 Jetta, I did quite a bit of research on the various synthetic oils for turbo diesel engines. I came away the most impressed with Mobil Delvac-1 in the SILVER jug. The numbers that were available online seemed to suggest that this was one of the better choices. I've run Delvac-1 since my Jetta's first oil change. Not the cheapest synthetic out there, but I've been happy with what I've seen.

Mine's had Mobile 1 since day 1. Up until 45K-ish it was 5w- or 10w-40(?) Anyway, I switched to 0w-40 and I know my milage is a tad better and I swear the seat of my pants tells me the engine has more... spunk.

Personally I use 8-10k change intervals on my Jetta, its rated for that, and i use the right oil.

when i had my 2000 Jetta TDI I used Shell Rottela T full synthetic. 5-40 i think. blue bottle you can get at your local mega-lo mart good stuff and cheap check there web site.

Actually, I changed my 85 Jetta from Delo 400 15W40 dino to Rotella T Synthetic 5W40 at 275K miles. Yes, you can do it.

I have used both 0w40 and 5w40 Mobil 1 in a 02 Jetta for a long time with great results.
