I have used Amsoil since 2012 and I haven’t went back to any other brands since then. The extra cost is for added protection and ease of mind vs mobile one.
Bottom Line
Yes, I would recommend this to a friend.

After rebuilding my engine in my G8 I switched to Amsoil after the 5000 mile break. It seems to run smoother and quieter. I used Amsol in my Subaru WRX and I’ve always had great results with it.
Bottom Line
Yes, I would recommend this to a friend.

My Classic Porsche runs better with Amsoil
By
Porsche recommended a change,
a
Verified Buyer
from
Texas

November 03, 2020
A couple of years ago Porsche updated their oil recommendations due to changes in oil manufacturing and environmental requirements. I had been using the recommended 0W40 viscosity oil but when I learned of the change I researched the additive packages and blend. Amsoil Signature 5W50 surpasses all of the criteria for the Porsche recommended oil. Since I began using the 5W50 15,000 miles ago I have seen better fuel economy, lower engine temps and easier starting. I did a bore scope of my pistons and they cleaner now than with the OEM oil. Considering the age of my engine (20 years and 118,000 miles) I need a reliable oil that has the properties of Amsoil Signature series.
Bottom Line
Yes, I would recommend this to a friend.
