Engine oil Mobil or Eneos

I once used the 20k mile oil, but changed it at 12k; my engine seemed to run nore smoothly, after that. I swore off longer oil change intervals and went back to regular Mobil 1.

It is good oil! The only recommendation for C5 Corvette's and other cars.

I've used it, no problems

Yes that's what I've been using for my 2020 hybrid.

Mobil 1 0w-30 AFE has the correct certification, I just used that. Easy to find.

This is a late response but I just saw your post and it's exactly what happened to me when I took my 2018 GSW 1.8 TSI 4Mo in for the 20k mi service. They filled it with 508 00 0W-20. I didn't catch it until much later and I changed the oil myself at 27k mi with Mobil 1 502 00 VW approved 0W-40 oil.

I did my own oil/filter change at 27k mi with Mobil One European Formula 0W-40, since I'm a little uneasy about 10k intervals in So Ca stop and go traffic and 100+ F heat.

I've been using 0W40 Euro Formula from Mobil 1 for years in both my cars. You will be fine running it.

As a Mercedes-Benz guy, I've used Mobil One European Formula 0w40 in them for decades. It is very good oil. I have well over a million miles on Mercedes-Benz cars using that oil with the extended (10K-15K mile) change interval with zero issues. Several of my cars have gone over 200,000 miles.

I'm currently happy with Mobil 1, 15w50, except when it comes time to pay for it, yikes that stuff is pricey. First time I ran the Mobil 1, guess what happened?? Oil light flicker at hot idle. Replaced the low pressure switch, no more flicker. That switch didn't change characteristics just because I changed oil, the fresh oil was thinner, oil pressure decreased.
