Engine oil Mobil or PETRONAS

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

My giulietta 1.4 MA is still reliable at 130k km. Never had any problems with engine always used recommended petronas oil. Had to rebuild my turbo once (at 120k km) it had very little play that made my car burn some oil.

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.

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
