Walmart sells Mobil 1 for so cheap that it doesn’t seem necessary to buy Walmart oil but the quality is fine.

Pros: quality is fine

Mobil Engine oil

I use **Mobil 1 Extended Performance 0W-20** or **Mobil 1 Hybrid 0W-20**, whichever is available. I use a **WIX 51348XP** filter, available locally or at RockAuto online. Do not buy filters on Amazon - there are a lot of counterfeits.

Pros: low contaminants, long life
Cons: counterfeits on Amazon
Mileage: 12000 km
Part number: 51348XP

It probably won’t matter much but I swear by Mobile 1 because I swapped to it in a vehicle that wasn’t doing well and it turned around and started running way smoother.

Pros: running way smoother

Please spend the money on quality oil. Use synthetic, 5W-30 or 0W-40 is recommeneded. Most of us use 0W-40 now, since we've found that 0W-40 makes the engine quite a bit smoother in sound and keeps it quiet.

Pros: smoother engine sound
Cons: dirty oil causes damage
Vehicle: Fiat 500

Castrol Engine oil

It\u2019ll be okay. Subaru engines are robust and that mix rate won\u2019t increase the viscosity enough to affect the oil flow rate out to the cams.\nPardon my skepticism regarding Castrol oils though. Haven\u2019t been a fan of them since the GTX days. The additives they\u2019d chuck in their generically sourced base oils glazed bores and gummed lifters.\nCost many a machine shop like ours a fortune in comeback work.

Cons: glazed bores, gummed lifters
Vehicle: Subaru
