Engine oil PENNZOIL or OEM Mazda

From what I've learned the best oil for the Turbo of any model with direct injection which Mazda uses is Pennzoil Ultra Platinum.

Change the oil at a minimum, and do it regularly. Use a quality synthetic high mileage oil and change it again in a couple thousand miles, then change on regular 5k mile intervals.

Use Penzoil Ultra Plat. Can probably stretch it to 5k miles with no issues.

I switched to 5w30 Pennzoil Ultra Platinum a long time ago on my 2.0T. 140k miles and running strong. FK8 CTR Turbo added around 133k, too. FBO PRL mods!

I have run 0w20 in my 2013 Mazda 3 skyactiv for 244,000 miles. It doesn't burn or leak any oil between changes. I change the oil and filters every 5-6,000 miles.

I run Pennzoil or Motul depending on if I grab filters locally (Walmart for Pennz) or buy an oil change kit online (most use Motul). I would have no quarrels running Toyota's oil (Mobil 1), Subaru's Oil (Idemitsu), Valvoline, or any of the other reputable brands in my car

have run penzz plat 5-30 for the entire life of the car almost, recently switched to the high mileage version as im pushing almost 150k miles on it.

i use pennzoil plat every 3k seems to be fine for the past 57k miles

My 2024 Toyota Rav4 Prime XSE has had 2 used oil analysis tests done at 4k and 8k miles on Pennzoil Platinum 0w-16 and Eneos 0w-16. Both results showed both oils shearing lower and out of grade to a 0w-8 viscosity at 100C in 4k miles.

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
