Best Engine oil for Volkswagen Jetta

I run mobil 1 synthetic 0w40 all year round, with no problems. Best of both worlds

I use Lucas oil in my motor oil for 1990 VW 1.6L Jetta diesel. I started using Lucas Oil because a relative of mine has been driving a large semi for almost 30 years, and he, like many in the trucking industry, swear by Lucas Oil. Judging by the parts per million of metal present in my motor oil, my motor oil with 1 cup of Lucas Oil, was wearing pretty well.

Yea I've used 5w40 syntec as well but seems like the dealerships in Canada are starting to use 5w30 and that I know for certain burns faster on my car. I'm not sure why the dealerships in Canada swapped over to 5w30 now but I always get Motul now. Although a bit more pricey, i intend to keep the car a long time

Me neither, I use the 5W-40 Syntec also and although I have a 2.5, from the 10k - 20k change it only used about .8 qts. If it's 502.00 it's a quality oil, doesn't really matter what it says on the bottle.

i've found that syntec 5w40 lasts, i've used otehr brands on my mkIV 2.slow and had oil consumption issues in the summer, but when i used 5w40 syntec i had no issues with burning oil, and have yet to see any with my 2.0T which is at 17000 km now, so its still kinda early to tell anything

I also have a 2006 2.0T Jetta and I have similar oil consumption rates. Try changing the brand of oil you use. I know the dealerships use Castrol Syntec. To me, it seems as if they're not as "durable". I swapped over to ELF for a while and that helped, and now I'm using Motul and this seems to be the best. I think my car burns around 1-2 qts every 5000kms.

i run it in my vr, 5w 30, full synthetic, it's nice

On that note, I currently have tried VW Oil from the dealer, Mobil 1, and Kendall Fully Synthetic and have determined that Mobil 1 5W-30 is the best mass-market oil out there to use. I run it 10,000 miles and the motor is as smooth as ever.

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.

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
