Engine oil Mobil or PENNZOIL

I went with Mobil 1 5w-30 ESP. I read around the Bob is the Oil guy and that is what I came up with what I would best for WRX that will be tuned with an intake (My opinion). I am sure there are other good options.

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

Other vehicles, I ruin normal Mobil 1 until about 80-100K miles and switch to high mileage. Put over 200K on a '04 Civic Si on all Mobil 1 and oil analysis came back great every time.

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.

I used the mobil synth high mileage 5w-30 for years in a 2001 accord lx 4cyl with 200k thru 274k miles when i sold it. Changed it about every 4k

My Tiguan and Passat all function perfectly with Mobil1 5W40, and I have used this oil for 15 years.

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.

It's a ok. Ran mobile one in my s50 sometimes rotella t6

If you have ever rebuilt an engine that used Pennzoil, you would never use it again. The top of the head will be covered in carbon.
