Best Engine oil for Volkswagen Jetta

I had a 2009 Jetta diesel that used a bit of oil until it hit 60000 miles, then it stopped and did not use ANY between the 8000 mile intervals I used.

I usually run 5-40 euro blend by valvoline from Walmart. $27 for 5 quart jug and you cannot beat that price. Walmart has the best oil prices of any auto part store.

Now the easiest one to find that meets my manual requirements is the Mobil 1 euro formula that’s the cool green color. The back of the bottle specifically states it meets VW specs.

I've always put Mobil1 0-W40 European car oil in my 2015 jetta since the day I bought it brand new but did notice they came out with a new 0-W30 oil but not sure if that's for the new jettas or not.

Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.

I like Liqui Moly in my 2011 Jetta tdi but been really impressed with how smooth my car is running on Total quartz and been using that the last few changes. Total Quartz = smooth

We exclusively use Mobil 1 (varying grades and viscosities) per the MFR spec and changing it at the MFR spec mileage (or time, during covid). Never any issues noted. 1985 BMW K100RS (122k miles), 2003 Boxster (177k miles), 2012 Acadia (98k miles), 2013 Jetta SEL (105k miles).

Part number for the oil: G055512A2 $14 (x2) O-ring: N90362001 $4 (x2) Paid ~$38 total Yeah my dealer is about 40 minutes away so I bought two in case I want to order oil in the future and do this again sometime...or if it leaks for some reason and I have to drain/refill, I just didn't want to drive back.

as long as it meets the VW 508 00/509 00 specification, it'll be fine which I think is 0w-20 and I \\*think\\* 5w-20

don't go beyond that, while it \\*may\\* not fuck the engine up, those 1.4Ts are REALLY picky (I had one in my Jetta Hybrid and anything past 5w-20 and she was angry )

Car has been at the stealership for three weeks. Same transmission TC seal leak. Bolts and seals also needed replacing. Car is 45 days old with 4K KM’s.
