Engine oil OEM Mazda or RED LINE
I use redline high performance 5w30 and I don’t burn a drop of oil even with 7500 mile intervals on my n54 powered 335is…With bmw synthetic my car would burn about a quart at 7500 miles.
Pros: no oil burn
Cons: bmw synthetic burns oil
Vehicle:
BMW
Mileage: 7500 km
I use Red Line in everything. The M3 gets 15w-50.

From my personal experience, I used to use Mobil 1 and Pennzoil Ultra Platinum oils, which are really high-quality oils. However, I did notice a big difference when I began using the OEM Mazda oil. I don't know what is so different about it, but my engine runs much more smoothly and very quietly. When I am at a stop light, I don't even feel the engine running, it's gotten that quiet, and I just hit over 100k miles.
Pros: engine runs smoothly, very quietly
Vehicle:
Mazda
Mileage: 160934 km
With the redline, my car barely burns any oil, and significantly less is directed to my catch can. Night and day difference.
Pros: barely burns oil
Vehicle:
Volkswagen
Redline is what I'm currently using for engine oil, shock fluid, and brake fluid.
Redline 5w-40. 6k mile intervals. Probably much nicer than what my little GTI needs, but I like supporting local businesses and it's amazing oil.
Pros: amazing oil
Vehicle:
Volkswagen
Mileage: 6000 km
I use Mazda Moly 0w-20 in our 2014 Skyactiv CX-5.

I use strictly Redline oils for all my fluids except premix. Engine oil is Redline 10w40.
Vehicle:
Mazda
Redline recommended 10w-40 Full Synthetic for my 1.8 solid lifter JH turbo application and the tech guy suggested modern synthetics don't cause seal leakage (like OG synths of 25 years ago) and holds up way better than the 40w rating in hot temps and protects much better when cold than even the current crop of Castrol 20/50 dino oil I was running. I swapped over the M81 to the same Redline oil and have not yet noticed any new oil leaks yet.
Pros: no seal leakage, better hot/cold protection

Volkswagen
I use only Redline for all my oils-fluids. For engine oil, I have used 10w40 consistently.
