Engine oil OEM Mazda or OEM Volkswagen

This one was done at the local VW dealership where they added 6L of VW oil and were nice enough to collect a sample of the oil for me to send off to Blackstone. The oil in this sample had higher quantities of wear metals present vs the 3rd sample, but that is to be expected as there were more than twice as many miles on the oil.

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 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

Many reputable rotary shops have tested numerous oils over the years, and agreed that the bearings do not have adequate protection with 5w-20 or 5w-30, especially if you track the car or do any spirited driving regularly.

Mazda’s OEM 5w30 is a little too thin for my blood considering the engine temps when driving hard, fine if you’re going to never redline the car

I encountered something similar when I took my CE Turbo in for service a few weeks ago. The invoice said 0W20 and when I asked the service manual why they used the wrong oil they told me “oh our technicians know what oil to use, ignore that.” Needless to say I have zero confidence that the correct oil was used.
