Customer Ratings & Reviews

I have use this oil exclusively on my 2013 Lexus GS 350. It is the best oil I've ever used. I found this oil as a step above the standard recommended oil from Lexus. It stays cleaner longer and allows for extended oil drain. I still change it at 10,000 miles or less because of the protection it provides. I know it's a little bit more expensive than the standard oil but my car now has 169,000 mi on it, and still running strong.

Been using Mobil 1 for years... did the engine flush and switch to this Amsoil Signature Series. Immediately I noticed a much smoother reving of the engine. It take almost nothing to get up to speed. Can't wait to change the other fluids as well. 100% Amsoil all around!

It’s the best

My wife 2019 Ranger has a 4cyl with a turbo. At 50,000 miles it has been flawless and I want to keep it that way. I change the oil and an Amsoil filter every 10,000 miles and the oil has been better than expected after 10,000 miles every time. These small engines rev higher and with the turbo I feel most confident with Amsoil oil and Amsoil filters that it has the ultimate protection.

Simply the Best

Best oil on the market! You really can feel the difference when you put oil between your fingertips. I trust this oil enough to run it for a year time frame in the car before changing it.

I have used this in all my autombiles for years. I change my oil every year and have not had any problems. The last car I traded had 180,000 miles on it and to my knowledge is still running.

This is a great oil for people who drive lots of miles. it also cuts Maintenace time because of its long life. It also offers great engine protection.

👍

I use both this oil and the 10/30 and they are both excellent with great support!!!

my engine is a little quiet than usually is after oil change

merci

Open test data, highest confidence that this is the best oil available.

Very good oil. My old engine runs very good and the fuel milage increased.

won't use anything else

I'm using Amsoil SS 5W-30 in all my Volkswagens! There feeling of the engine is apparent from start-up to hard acceleration with a 2.0L turbo gas motor. I only use the best oil for everything, no compromise. Amsoil SS 5W-30 will keep your engine safe and clean.

Oil delivered fast and good. Thank you very much

Best oil money can buy!

Amsoil is the best product out there I have been using it in everything I own. Shipping is super fast and very friendly people

Usually everything goes well and deliveries are within 3 business days which is awesome, but I have been waiting for my order now for two weeks and no sign of it, had to cancel service on vehicle because order was a no show, no tracking number to check on status just that the order was shipped. We don't live that far away so I am not happy and very disappointed.
