Engine oil PENNZOIL or RED LINE

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.

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.

Pennzoil UP was on a sale and I bought 15 quarts, my Sierra dropped a lifter within 200 miles of the OC and switch, related, no way, will I ever use Pennzoil UP again, no way.
