Engine oil Mobil or Castrol
I’ve been feeding mine Mobil1 or Castrol GTX, whichever one is cheaper.
I run Castrol (bought at Walmart), like my father and his father did before me...
Walmart sells Mobil 1 for so cheap that it doesn’t seem necessary to buy Walmart oil but the quality is fine.
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.
Ive been using 0w40 mobil1. Had 2 jetta one 2011 wasn’t deleted car went till 502k km till it got hit into a ditch
I use it in my non deleted CJAA (dumb) but I haven't had any issues (yet) and it doesn't burn oil.
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.
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.
Castrol is fine
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.
