The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.
262k miles here on an M54B30 with 10k changes, Mobil 1, it's running great.
It should be fine. I use Mobil 1 and it's worked great.
I really liked Valvoline, good quality, reasonble price.
Valvoline Restore & Protect or Pennzoil Ultra Platinum are also great oils to run and clear up and baked on sludge.
Buy Valvoline oil, and maybe it's a good time to switch to 5w-30 in it.
I use Mobil one in Canada when it goes on sale synthetic 0W20 10 k intervals 13 yr old corolla 1.8 and 15 yr old tundra 5.7 350 k and 320 km ; no oil consumption work great
You must use Mobil 1 0W40!
My last [Blackstone-labs.com](http://Blackstone-labs.com) report came back with 1.8% fuel dilution. 2021 1.5T at 23kmiles, 6800 miles on the oil (0w20 Valvoline R&P).
I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
