Engine oil Castrol or OEM Volkswagen

i use castrol 5w-40 european vehicle. fully built and no issues at almost 30k

I use the Castrol Edge oil. I was doing 7500 mile oil changes and on this last one bumped that up to 10k miles. I sent out the oil for analysis to decide if I want to step up to an even larger interval. The comments left by the tester: 'Your CX5's engine looks good in analysis! Your results look really good by comparison after the 10,000 miles. Metals are all within good wear ranges, with iron even showing below-average steel wear. Nice! Titanium is just an additive in Castrol. Very nice! Go 12k miles next fill.' I will heed their advice and go 12,000 miles on this next one.

Doesn’t sheer down…

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.

I used Castrol edge cos that's what my audi used from the factory.

I used Castrol oil and was not satisfied but this oil till date has helped alittle with consumption as well.

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.
