vs
Engine oil PENNZOIL or IDEMITSU
I use Pennzoil Ultra Platinum 5w-30. It’s hasn’t failed me yet and I’ve done multiple track days
Pros: hasn't failed me yet
Pennzoil ultra platinum 5w-30 in my 2016. Will use it in wife's 2025 when warranty is done.
Honestly, any brand should be okay as long as you change your oil every 5k miles. Personally I run Penz ultra plat. I never burn oil with it and my engine sounds quieter than it did w/ Mobil 1.
Pros: engine sounds quieter
Cons: never burn oil
Vehicle:
Lexus GS
Mileage: 5000 km
Put about 300K on two different M54's so far. Originally Mobil1/Castrol 0W30 (that was the original BMW recommendation in early 2000s), eventually switched to Pennzoil Euro 5W40 for oil leak reduction.
Pros: oil leak reduction
Vehicle:
BMW
Mileage: 300000 km
I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.
Pros: runs lovely and smooth
Vehicle:
Mazda
I switched to Pennzoil Ultra Platinum full synthetic made from natural gas. Oil consumption is 1/2qt in 5K.
Pros: reduced oil consumption
Mileage: 8047 km
I flip between Pennzoil Ultra Platinum and Motul depending on if I choose to order ahead of time or just do it when I feel like.
Pros: Easily available
Pennzoil Platinum Ultra is also commonly used/recommended instead of the Motul and is cheaper.
Pros: commonly used, cheaper
I always use Penzoil Ultra Platinum and have never had an issue.
Pros: no issues
Vehicle:
Subaru
On the Gen 2 Prius that have been several reports of Pennzoil Platinum full synthetic consuming oil much quicker, me included.
Cons: consuming oil much quicker
Vehicle:
Toyota Prius
