Engine oil PENNZOIL or OEM Subaru

0-20 pennsoil synthetic with a wix or napa filter

Unless you are tracking the car you aren\u2019t going to see a difference. I use Pennzoil ultra platinum and a wix filter on my daily\u2019s.

Pennzoil Ultra Platinum, better than mobil 1, but also I am pretty sure all oil is within a few percentage points of performance anymore anyways, and it really doesn't matter as long as you change it when you should.

Great oil, I go with the Ultra Platinum. So far it's been the absolute quietest (based on subjective valvetrain sound) and smoothest driving oil I ever used. I tried OEM, Valvoline, Castrol. Nothing was as smooth as the Pennzoil even after a few thousand miles. I still change it every 5k for peace of mind.

I swear by penz ultra platinum/euro platinum in my cars. Really good anti wear additive package in that stuff.

I use Pennzoil Platinum. It's made from natural gas, a cleaner base than crude. My engine loves it. Minimal consumption between oil changes and no leaks.

I went with Pennzoil Ultra Platinum 5w-30. 20k on the clock of my 2023 and it doesn’t burn a drop of oil. I changed the oil at 1k and 3k after that and it always comes out looking beautifully.

Pennsoil 0w30 is a great oil

0w20 provides your engine with more wear protection .

There is minimal difference between 0w16 and 0w20, with 0w20 provided marginally better wear protection and 0w16 providing slightly better fuel efficiency since it's slightly thinner and provides less internal resistance.

5w30 pennzoil, doesnt make the vtc rattle with that oil, mobil 1 sucks i would stay away from it it also burns much faster
