Engine oil Mobil or Castrol

In my 323i with the 2.5L N52 engine, I use Castrol Edge 5w40 with the appropriate LL specification. Oil consumption is 3000 km per liter, with 190,000 km on the clock.

Castrol is really good considering cost and quality.

Personally I do 10k miles with Mobil 1 high mileage and a Walmart Supertech filter on all my vehicles and they're all well over 300k miles with no oil-related issues.

I would choose Mobil 1 Extended Performance if you're going with Mobil 1. It has the best addative package of the bunch. It's what I run because a 5Qt jug is $28 or less at Walmart.

I use Mobil 1 extended performance oil just to get that extra protection for a mere $3 premium compared to regular Mobil 1.

Mobil 1 FS is what I use on every car/motorcycle I’ve ever owned. Never let me down

I replaced the plugs, oil/filter and air filter with oem parts when I got it. I\u2019ve been changing the oil at 5k intervals with the recommended Castrol 0w-20.

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 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.
