Engine oil PENNZOIL or AMSOIL

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

if you to go for the best oil and the most expensive ones, you can use liqui moli, valvoline, ams oil

I'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

AMSOIL Signature Series 5w-30 with a black JDM Subaru Filter is the superior combo.

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.

I recommend Royal purple XPR, or amsoil zRod.

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.

personally, I think Amsoil AFL is junk. They ruined a stout oil when they reformulated it to mimick 505.01.
