Engine oil Mobil or VALVOLINE

As long as the oil is VW 502 00 spec, it’s fine to use. I always go with either Mobil 0W-40 or 5W-40.

I use Valvoline Restore & Protect, which claims to clean your engine and reduce friction/wear more than any other oil

Mobil 1 Advanced in everything, with OEM filters... Use it in my Tucson, Mustang, Corvette, and Dodge pickup... Really, any quality full synthetic oil is fine.

Been using Mobil 1 5w-30 full synthetic since I rolled it off the lot. Zero issues. I do my own changes every 3-5k. I did swap out to the FL400s filter to make it an even 6qts.

I went back and forth between Mobile 1 and Amazon full synth for 140k miles without issue. Just change the oil every 5000-7000 miles

Mobil 1, Valvoline, or Motorcraft. Ive used them all and have no complaints so far, usually i use Mobil 1 since i can find the 6 qt box for a decent price at Costco.

I use Valvoline Extended Protection Full Synthetic 5W-30.

Very good on engines and your turbo especially (i have a 2014 st3)

I personally use Mobil 1. They all do basically the same thing if you're changing it often enough. I change mine between 3-5k miles typically.

I used the mobile advanced fuel economy, I live in a pretty mild climate. I have seen lots of people swear by asmoil it's supposed to be good.

I usend to run syn 15w50 in my tired old vr6 all year round, it helped with seeping issues, lifter noise and all if that. but the oil pressure would be through the roof during first start. so I'd set aside a few mins in the morning to let the car idle, relax, listen to a song and let it get some heat in it. on a normal day, the star up pressure would be .5 bar past the filter bypass (10 bar), warm idle was 2 and a bit, and everything above 3.5k was back to the bypass.
