Made the motor seem a little more noisy then with the factory oil in it since I got it but no issues other then a louder motor noise. Jeep FCA said it's normal and nothing to worry about

Everyday driver

In my book proper engine oil is a must these days, under hood and engine temps are hotter due to emission reasons. Cold startup also a factor for wear. I’m a firm believer that oil (good) oil is cheap insurance and peace of mind knowing that it will protect my engines for whatever demand I put on them. Keep up the good work !!!
Bottom Line
Yes, I would recommend this to a friend.

Excellent 0w'16
By
THOMAS,

Verified Buyer

WI
on
August 25, 2026
I put Amsoil Signature in a 2022 Toyota Corolla for a couple reasons. If I have to use thin 0w-16, it will be the best engineered oil I can find, and last through the Summer heat, and subzero Winter starts. I believe the specs show Amsoil is going to do the best job , and with enough volume purchased the pricing isn't much more than other oils. I run it in all my cars.
Bottom Line
Yes, I would recommend this to a friend.
