Engine oil Shell or PENNZOIL

I tried to use the Pennzoil high mileage full synthetic the most, but if I didn't have the bit extra for it, I'd get Walmarts generic full synthetic high milage. I always used a Fram full synthetic filter too, they were the only ones around me that were better quality and decent price for the time. Mine got to 200k no problems!

Started running penzoil platinum in my mazdaspeed due to the great UOAs it got on DI motors, and just now run that in all my shit to simplify my life. Only have to keep one oil around that way.

I have a 2001 Forester L and I enjoy using Castrol Edge 5-30 during winter and Rotella T6 5-40 during the summer in Arizona.

I’m on rotella t6 on my ‘05 Impreza at 217k miles. Just had all the seals replaced. It has been on rotella since 132k miles. Runs really good.

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.

I live in a dusty climate I change my oil at least annually and I use Mobil one in my Volvo, Kirkland synthetic in the kids cars, and rotella in my air cooled vw.

I use Rotella T6 5W40 on my stock motor STI.

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.

now im using shell long ride currently at 1500km and i havent feel any vibration yet and its cheaper than amsoil.
