Engine oil PENNZOIL or IDEMITSU

I usually buy Pennzoil, it's inexpensive and it works. I check the contents first to make sure the oil isn't full of gunk in case someone swapped it. I do oil change every 5k km, which is once every 2-3 months, hence I don't worry much about too much gunk as I flush it out often.

I use the Penzoil Platinum Euro LX Full Synthetic 0W-30. No issues past 2 oil changes.

The oil for our car is VW 504.00/ VW507.00 the 504 spec is 0W/30 and the 507 is 5W/30 only difference is fuel economy and the 5W/30 is the better choice i have used Penzoil Euro Lx for 0W/30 and oil does get by rings so might see puff of smoke on initial start, but with the 5W/30 Total nothing.

I flip between Pennzoil Ultra Platinum and Motul X-Clean both in 5W-30 depending on if I order ahead of time online or just go to the store/dealership for parts. Both have been good, just make sure to keep up on maintence schedules and you'll be fine with pretty much anything

Pennzoil Platinum or Ultra Platinum 5w20 and WIX 57060 (non XP) filter. I bought my truck with around 40k miles, it now has 90k and have had no issues with the motor changing the oil every 7500 per Blackstone's oil analysis I sent in not long after I took ownership.

Pennzoil Ultra Plat.

My dealership usually overfills my car and I do not think they use Toyota 0w-16 based on oil tests I have done. I do my own changes and switched from Toyota 0w-16 to Mobil 0w-16 and landed on Pennzoil presently and going forward.

I run penzoil ultra platinum. I’ll spend the extra money to know that I might get a few more hours out of my gen.

Luckily modern oils are developed with this in mind. Costco/walmart/amazon oil is made by the same company, Warren oil. I think most people consider penzoil ultra platinum as one of the best.

I would run Castrol over Pennzoil. Coming from personal experience, Pennzoil is junk.
