I use Pennzoil ultra platinum and my car runs great I change it every 5K. I use mazda oem oil filters since they don’t have the anti drain back valve.
I’m slowly switching to Mobil1 since I started doing oil analysis.
It has no sodium and therefore a good way to see if there is a coolant leak.
Pennzoil high mileage synthetic. I've burnt/leaked far less fuel since I started using it.
I use Pennzoil Platinum after FordBossMe turned me onto it and did some (quite detailed) review videos covering it versus the other ones such as Mobil1 and Valvoline
Pretty much as soon as I switched to Pennzoil Platinum (the one made from natural gas) my engine ***suddenly*** got noticeably quieter. Previously with the Mobil1 it was making faint clicking/lifter noise during the first few minutes of driving
Starts are quieter too, with the Mobil1 it made some light clatter/metallic-y noises on those very first 1-3 seconds of startup, but now with the Pennzoil Platinum it purrs up smoothly from the moment I turn the key
I use Pennzoil Platinum Full Synthetic in my 21 Forester. $23 for 5qt from Walmart and $12 oil filter from dealership.
Project farm did a bunch of tests on all popular oil brands and amsoil won followed closely by pennzoil ultra platinum. The pennzoil is easier to get so that’s what I use on all my cars.
I've used Mobil 1 in my 2011 Mazda Speed3 for 8 years. My 2019 Bullitt gets Mobil 1 as well. Mobil 1 is reasonably priced and meets the spec required by both cars.
Mobil 1. I've used it in all of my cars. Two of my mustangs lasted until 240k before needing a rebuild.
Mobil 1, my 05 GT with 150k miles on it getting cams a few weeks ago looks clean inside. I've had the car since 70k and Mobil is all I run in it.
LiquiMoly is fine. I used 0w40 Mobil 1 as I do in every single one of my cars for the last decade and it’s absolutely fine.
