Owner reviews for engine oil

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

I prefer synthetic myself in my CX50 Turbo, but Mazda engines aren't very picky overall.

Mines a secret inbox me and I'll tell you ..lol

Amsoil 100%, I tested it quite a few, and I’m noticed the least amount of decoration and power loss with it

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

I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.

5W-40 is my preferred viscosity for the N52. If you are only topping off, virtually any API SL or newer oil will work just fine. If you are doing a full change though you should source a 5W-40 that meets BMW’s LL-01 specification.

As long as it’s a LL-01, you can put that in. I’m currently running that on my N52.

If you are using ToyotaCare, they will push 10k/1yr oil change interval. If you willing to pay for every oil change, they don't care.

Dad got a Monroe oil change, got about a mile away before his oilless engine seized
