Started using AMSOIL after watching a comparison between it and Royal Purple. AMSOIL has proved superior. I usually run 250-500 miles over oil change intervals. AMSOIL always drains with amber color still in the oil. Not jet black or tarred up.
Amsoil OE series is far superior to any other synthetic on the shelf today. I use it in a 2001 car with over 250,000 miles and change the oil once a year as i do with all my other vehicles. Killer line up of oils!!
Bottom Line
Yes, I would recommend this to a friend.

If you know your car, you can feel when it’s running smooth. You can feel the difference with Amsoil. They don’t use gimmicks like colors to impress. They make a great product that speaks for itself.
great oil for fiat engines that are so picky about the oils weight
Bottom Line
Yes, I would recommend this to a friend.

I’ve been using Amsoil oil for years. I’m truly convinced that this is the best motor oil in the world! Bar none! Want your engine to run like an old sewing machine. Then don’t comprise the oil you use.

I have an old riding mower that just had the engine replaced. While I haven't pulled the old engine down yet, I'm pretty sure the failure is related to oil failure. So we spend a little more on a good oil to keep the machine running for another decade.
I have a 2013 Ram 1500 with the 5.7 Hemi in it. I have always ran Mobile Full Synthetic in it since I bought the truck. I bought Amsoil 5w20 Full Synthetic to go in my truck. I ran seafoam in my oil to clean the inside of my motor. I changed the oil/filter to Amsoil 5W20 Full Synthetic and couldn’t be happier! The Hemi just loves the Amsoil 5W20. Thanks Amsoil

My wife is Rural Postal Carrier, so she runs her Jeep hard everyday, a lot of quick takeoffs and many stops. After 5000 miles the oil still looks good.
Bottom Line
Yes, I would recommend this to a friend.
