Engine oil Mobil or OEM BMW

Mobil 1 . When my engines run smooth, makes it worthwhile. Any newly changed oil is better than any old oil. But Mobil 1 > Rest of ‘em.

I used to use German Castrol 0w30, then Belgian Castrol 0w40, now I use Mobil 1 Euro 0w40 in most applications. Intervals of 5000 miles Every engine I've had ran great under this regime.

Mobil 1 0w20 ESP. Advance Auto and some Walmarts have it.

I used to get my 0-40 Mobil at WalMart for my Audi, because they were the cheapest.

Mobil 1 Advanced 15w50 automotive oil. Yes you heard me right. No it doesn’t cause clutch to slip. $25 for 5 quarts at Walmart. Best protection against friction and wear money can buy. 11k and zero issues. No metal shavings on drain plug after break in with factory oil.

Audi uses Mobil 1 at the dealer level. Stick with that.

I've been using Mobil 1 0w30 in my NA 2018 CX5 for 180,000 miles , no issues and runs quieter than 0w20 .

My daughter has a 2016 Civic bought new. First oil change was at 200mi with Mobil1 Extended, and then oil/filter changes at 15,000 or 20,000 mile intervals until 86,500. Switched to Restore and Protect and after 1k miles I changed the filter and cut it open, there were zero sludge deposits, and oil color looked new.

5w40 if its drinking oil during vtec, I usually use Mobil but get whatever cheapest

Oil consumption is a common problem. My original E92 consumed a quart of oil every 1K miles. My current car does not.
