Engine oil PETRONAS or OEM Volkswagen

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.

2008 VW Beetle is a 2.5 liter 5 cylinder. Yeah, 5 cylinder. It takes 6.3 quarts

I ran this exact oil in my late B5.5 1.8T, and it worked great, until some lady blew a stop sign, t-boning me and totaling my car. But it wasn't the fault of the oil, lol.

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

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.

Well, just got back the test results on for our oil analysis, here are the comments: " Nothing showed up in this sample that's too much of a surprise, though aluminum and copper are perhaps a little higher than expected. New parts wearing in tend to leave a lot of metal in the oil and that's what we suspect is going on here. You ran this oil pretty long for factory oil (we realize you were probably only following the oil life monitor). So that's why aluminum and copper are on the high side. No matter--everything should improve now that you've changed this fill. The TBN read 1.9, getting low but still okay. Potassium is from the EGR system. "

My Mk4 Golf is at 146000. And I've religiously changed oil and filter every 4000. One time I let this synthetic oil go for 9000 miles, it caused pre-ignition and destroyed 2 sparkplugs, needed a tow, and a expensive sparkplug replace at VW.
