Engine oil PENNZOIL or AMSOIL

Any synthetic - I like the Amsoil.

I run 5w30 in my 17 tundra, 16 Corolla and soon my 23 4Runner. My Tundra was noticeably quieter after the switch. The Corolla was quieter, but the change was not as dramatic as the 5.7 V8 in the tundra.

I use Pennzoil Ultra Platinum because it is GF-6A and API SP full synthetic motor oil which are the latest and greatest standards.

I use PENNZOIL PLATINUM but brand is up to you !

Pennzoil ultra premium is the best overall considering price, pennzoil euro is even better if they make it in your w-viscosity rating.

amsoil is the best period but is also expensive. recommended for commercial driving where you run your car to the limit racking up hundreds of miles per drive.

A lot of old guys recommend mobil 1. Mobil 1 loses to even walmart supertech, amazon basics oil, valvoline, etc. in the wear metal tests so that's my reason for avoiding that one

I’m using Amsoil Signature oil.

I’m running Penzoil ultra platinum 5W-30. The instructor I drove with said he runs 5W-30 in his gen 1 BRZ track rentals.

Yesterday I took my car in for an oil change and got amsoil. I read countless comments of people hating on the price, this and that, but let me tell you somthing, that amsoil ain't a gimmick or a rip off. My car drove sooooo much better afterwards, it kinda shocked me. Smoother, seems faster, more. Consistent shifts, just left me feeling like she felt the best version of herself.

Have an 07 Silverado bought new first oil change switched over to Mobil one used that until one of the hurricanes hit Louisiana and started having a problem getting it so switched over to Pennzoil full synthetic. Truck has 368000 on it and seems to be still going strong so I’d say it’s your choice.

Those guys don't replace you crush washer, and the oil the use is crap.
