Engine oil Mobil or Shell

I have always used shell 10w-40 and did regular oil changes around 4-4.5k. Faced no issues what so ever, engine was still healthy, no oil consumption, almost same performance.

Mobil 1 0W-20 wix filter 7500mile intervals. Due for 30k change right now. Honestly the oil I\u2019ve drained out so far still looks really good but I buy my Mobil at Costco so still relatively cheap to change.

I’ve been feeding mine Mobil1 or Castrol GTX, whichever one is cheaper.

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.

I run rotella T6 5w-40. Have for 120k miles and will for the next 120k

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

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.

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 sent a few samples from my Ecoboost 3.0 to Blackstone Laboratories at 5k miles each. Mobil 1 and Pennzoil Platinum, both used Fram ultra synthetic filters.Oil was pretty much cashed out. I couldn't imagine going any further than 5k.
