Engine oil PENNZOIL or OEM Honda

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

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 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

I go every 5k using Pennzoil Platinum 5w-30, though it's just a stock engine/tune and more than half are highway miles

The engine itself runs great with the 48K I put on it in the past 2.5 years with biannual oil changes (Pennzoil Ultra Platinum). Averaging 27 MPGs on 91 Octane hwy miles, 24-25 mpg in the city.

I've been using Penzoil ultra platinum full synthetic 0w-20, though it does burn sometimes a quart every oil change.

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
