Engine oil PENNZOIL or OEM Mazda

Honestly, I just use Pennzoil Platinum for the past 7 years. but now I feel like reliability depends on the user, just keep up with the oil changes at least every 3k and if you’re abusing, just watch your oil temps. I have 145k miles and I abused this car since I had it at 0 miles. Still original motor and tuned by Admin.

Since switching to Platinum there are no oil leaks and less than a qt. to top up between changes.

Pennzoil Ultra Platinum usually or Castrol Edge. In North Texas I’ll run a cold grade of 10w in summer and usually 5w in winter. 40 or 30 summer hot viscosity/ weight and 30 winter. 4.2 version of your 4.0 S/C AJV8.

Older high mileage car: Pennzoil High Mileage blend. Works better for me than Valvoline MaxLife to reduce gasket seeping and weeping.

I use 5w30 Pennzoil platinum and a Fram Endurance synthetic oil filter in all my Subes.

I personally use Pennzoil Platinum in my Ascent and Mobil 1 in my Crosstrek, mostly for cost and availability reasons.

I’ve been using Penzoil Ultra Platinum in my Jeep and it’s been running great, so far lol. The cold flow properties of the oil I use is really important because the winters here can be rough, thus why after watching that video I swapped to it.

Pennzoil Ultra Platinum in all my cars.

I'm using Pennzoil Platinum Euro 5W40.

I got an oil change with Pennzoil 5W-40 Euro, which I was not too fond of, because the light weight of the oil made my lifter noise sound much more pronounced.
