Engine oil OEM Subaru or OEM Volkswagen

Check all your fluids ASAP. If any are low, top off as per the manual and monitor closely before you leave to make sure it's not leaking or consuming anything. Definitely bring extra oil, 1 or 2 quarts would be pleanty, and some paper towels and rubber gloves help too.

Should be fine, but CHECK THE OIL FREQUENTLY. This series of engines is notorious for oil consumption problems, which may not appear at all when doing short trips, but suddenly it's drinking 1qt or more per 1000 miles on the highway.

Take a quart of oil with, especially if you don't have reliable data on how much your engine burns. Check it occasionally and top off if needed.

I did first oil change on Atlas at 5k then did 10k changes, but the 3.6 is lethargic compared to the GTI which I have been doing about every 4k miles.

I've added only one quart of oil to all the VWs I have owned over the past 35 years. I check the oil every 3 months, and get the oil and filter changed annually. I don't think that modern engines consume oil, at least, not for the first 100K miles of their life.

None of my MK7, 7.5 GTIs or GLIs consumed any. Nor does my MK8.

After 6 months of ownership, I have not lost any oil/ needed to add any oil. My MK7 1.8 TSI Golf SportWagen was the same way. Never needed to add a drop between the 10k mile oil changes. Not complaining at all. Quite the contrary. Just hit 6000 miles and the oil still looks new. I was originally planning on 5k mile oil changes but decided 7500 miles makes more sense for me at least.

Just keep the right viscosity oil in it and monitor the oil temp. You might be able to read oil temp from you ECU through the obd port. 120-130C is very ok with good synthetic oil.

I blew up a VW polo with the wrong oil and high oil temps.

Wife has a 2015 jetta with the 1.8t and burns 1L every 500 -700 miles. My 2016 a3 burns relatively nothing but maybe half a liter every oil change interval and has same engine.

After reading this thread I decided to check the paperwork on my oil change that I got from a dealer last week. All it says is 6 G-E60-020-1B-DSP ENG. OIL Net 7.80 Total 46.80 which I assume means the "6" is the quantity. As far as I can tell, that part number equals VW 508.00 Spec oil. My car is a 2019 1.8L and the label under the hood clearly says 502 or 504 oil is required.
