Great oil for your engine with outstanding protection!

Used on my ram 1500 5.7 and i couldn’t be happier, every once in a while i check the dipstick and its still golden which is crazy

Great oil, extremely great quality and I am very satisfied and will continue to purchase amsoil.

Great oil

Extremely happy with this product.

No issues, been good so far, used this due to my experience running amsoil in an exoboost, i expect a similar result

Everything’s easy to find, and I get free shipping every time I order my case of oil. Plus, it always arrives fast.

I'm a 50 year technician and my entire carrier has been to do the best repairs for my customers. A very good oil is pertinent to a good repair. AMZOIL does that for me and my customers.

Switched my 2003 honda crv 240,000 Miles over to amsoil 5W20 and like my other vehicals the result was a quieter, cleaner and smoother running engine, Amsoil doesn't stop amazing me everytime.

Only the best oil for one of the best off road vehicles made. Goal of 500,000 miles. So just getting started with the right oil!

Bought it for a 2025 Toyota Highlander Hybrid when Amsoil was the only oil I could find in 0W-16. Very happy with it and sticking with it!

High quality oil

Very good oil and American 🇺🇸 made.

I've been using Amsoil Synthetic for several oil changes now in my GMC Sierra HD2500 work truck. The engine in this truck gets worked hard with most of its 85K miles spent towing a big Dustless Blasting DB800 trailer on these western PA roads. From highways, to winding and hilly back country roads, to gravel roads, even off road, this engine has performed flawlessly, and I know the Amsoil engine oil has contributed to that performance. I will not use another oil in my truck--you don't mess with success. Not only does the oil perform well, but also the service is top notch. I get items from my online orders within a day or two, and they are always correct. Running a small business is full of headaches, but my engine oil isn't one of them. Thanks Amsoil!

I have done four vehicles oil change and everyone has noticed how smooth their engine is running. Will continue to recommend this product to everyone.

Just recently changed our HRV from M1 0W-20 EP to Amsoil Signature 0W-20, does seem a bit quieter, time will tell. I have confidence in this oil.

I've been using Amsoil products for too many years to count and I have never been disappointed with the quality and performance of any of their products.

First time using this oil. But if it's as good as the diesel oil it will be awesome.

Would not put anything else in my vehicles.

Did my first o/c at 1,000 miles & then again at 3,000 on my new ‘25 Ranger Raptor with the 3.0L Ecoboost and instantly switched it to AMSOIL 5w-30 full synthetic and that’s all this engine will ever get from here on out. Now I’ll settle into 5K intervals. Cheap insurance as I do it myself. Had nothing but success with this oil on my last 2019 F-150 with the 3.5L Eco. These twin turbos engines are synonymous for reacting negatively with the cam phasers & whatnot to low quality & dirty oil and low maintenance. Followed the same 5K routine and used the same AMSOIL and when I traded that F-150 in on this Ranger with 135K I had never as much as had an ounce of engine or cam phasers rattle troubles. So I never considered any other oil brand options. Returned back to what has already proved itself to me. AMSOIL.
