Engine oil PENNZOIL or AMSOIL

Amsoil 5W30 SS, I run E85 so I wanted something I could trust to handle fuel dilution

I use full synthetic all the time, either Pennzoil Platinum or Mobil 1.

I personally like Amsoil better they actually created synthetic oil but I don’t believe in 25,000 miles on it oil change if you want to run it for like 10,000 and change the filter halfway through 5000 I believe the Oil Wall hold off no problem bye just seems like a lot of miles to put on oil

AMSOIL ALL THE WAY!!!

Coyote tick is practically gone and I’ve tried Motorcraft, Penzoil, Mobil, Royal Purple, & Castrol. Amsoil is a little more $ but 100% worth it.

I ran Pennzoil XLF in all my two strokes for years with no probs. Good price and readily available at Wal-Mart, Amazon, etc. Quality oil and lower smoke than many.

Amsoil 10W-30 Signature Series here. It's on the expensive side but it's 100% synthetic, tests great, and made in the USA.

I have ran Amsoil since day one on my 2016. I change oil once a year currently sitting at 156,000 miles, no issues knock on wood.

Been using amsoil for a little over a year now and it's really quiet.

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.

Amsoil. My s2k burned just about every oil when I beat on it until I started using Amsoil.
