Engine oil Pentosin or OEM Volkswagen

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 got my 2018 Sprinter and so have used the Pento HPII in that as well.

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.

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.

Pentosin is fine, Mobil 1 is fine, Castrol, whatever. I put Mobil 1 in my racecar but castrol in my daily because it burns oil and I want a heavier weight that I can't find Mobil 1 in. Pentosin or LiquiMoly are good, but don't put too much thought into it.

My previous MK7 GTI used a quart about every 3K miles from the day it was new until I traded it at 212K.

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.

This is not fine. VW oils like 502, 504, 508 and 511 are not typical oils. They have a different additive package and the viscosity is different, like the extended performance 5w30 is not the same viscosity as a 504 5w30. The 504 is thicker and is closer to a 40w.
