Engine oil PENNZOIL or IDEMITSU
I’m using Pennzoil Ultra Platinum, really helped how effortless my acceleration is and gas mileage.
Pros: effortless acceleration, gas mileage
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!
Pros: better quality, decent price
Mileage: 200000 km
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.
Pros: great UOAs
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.
Pros: reliability depends on user
Mileage: 145000 km
Since switching to Platinum there are no oil leaks and less than a qt. to top up between changes.
Pros: no oil leaks
Idemitsu all day. It’s synthetic but what needs to be emphasized is the ingredient blend is purpose designed for a rotary to make the right lube + burn.
Pros: purpose designed for rotary
I've been running that exact oil in my rx8 for about 1k km now and its still as smooth as ever
Pros: still as smooth as ever
Vehicle:
Mazda
Mileage: 1000 km
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.
Pros: cold grade of 10w
Older high mileage car: Pennzoil High Mileage blend. Works better for me than Valvoline MaxLife to reduce gasket seeping and weeping.
Pros: reduce gasket seeping
I use 5w30 Pennzoil platinum and a Fram Endurance synthetic oil filter in all my Subes.
