I've seen lots of videos showing the Valvoline restore and protect oil helping to clean engines. If you go that route I'd recommend replacing the oil filter after 500 miles then again at 2500 miles to keep the filters new for any gunk that gets freed up.
Use Valvoline Restore and Protect oil if possible
I use M1 5-30 because I've ran it in well over a dozen cars and beat on all of them without issue, and it's only $28 for a gallon jug at walmart. I also run liqui moly ceratec to silence the typewriter tick it developed around 35k.
Valvoline full synthetic, 5w-20, She has 151k and counting.
Use only Valvoline restore and protect every 5 k miles. Keeps engine clean keeps and oil use normal
I recall mobil1 going red being normal.
If it's burning oil try a few change intervals with Valvoline Restore and Protect. It's supposed to remove deposits on the piston rings and reduce oil consumption.
Mobil 1 ESPx2 is the right choice here. The regular 0W-20 does not carry the VW 508 00 approval, whereas the ESP one does. It’s a great oil to use!
I only use Mobil1 High mileage. Everytime I drop the oil at 100%, it feels less oily? Kinda less slippery? Definitely darker than I would like. My feeling is change it a little early.
I learned mobil 1 is the absolute worst oil to use in Subaru engines, especially ej257. Simply because it is good oil but because of the poor oil cooling the detergents burn in the engines causing premature wear.
