Customer Ratings & Reviews

I'm a new customer , 40+ year technician. I am always looking for the best product to maintain my vehicles. At this time will continue use AMZOIL and will be able to determine how I like it.

I have only had the oil in my car for a month, but i have had no noticeable problems. My friend has been using it for several years in his vehicles and is extremely pleased with the performance.

I'm a big believer in oil changing. With a new car I change it at 1000 - 2000 miles. I had one truck which had a magnetic drain plug. There were so many shavings it was hard to believe it was a modern engine. I think it is better to change the oil and filter in the early days. With my current new vehicle, during the warranty period there is a free oil change after 1 year or 10,000 miles. I would never go that long so I had already changed it once to Amsoil 0W-30. The oil usage rate was reduced dramatically. After my included warranty oil change using the manufacturers recommended oil, the increase in oil consumption was easily noticed. After 5000 miles I changed back to Amsoil, and again the oil consumption is dramatically reduced. The Amsoil is only slightly more expensive than the recommended oil.

First time purchasing this oil. Obviously the cost is a bit more than other oils, but most of the long term reviews help justify the price. A cleaner engine will have better mpg and ultimately last longer.

I like using this oil in my 2014 4Runner because of its longevity. I plan to change my oil regularly, but if I don't hit the dates or mile exactly, I like having the built-in safety of this long mileage oil.

Long lasting

I love AMSOil! This it the only product I use in my 2016 F150 Roush Stage 2 truck! I definitely recommend to everyone.

Just over a quarter of a million kms on the vehicle and no signs of any problems etc. Engine silent and smooth. Oil change every 25,000 kms or one year so easy to track.

Been using this oil for 23 years and have nothing but good things to say about it!

There is no better motor oil on the market than Amsoil Signature. Matched with an Amsoil oil filter, you have premium protection for an entire year.

Great oil

I have been using Amsoil for years and believe it is the best oil available. I also use their oil filters so I can go one year between oil changes. very convenient.

Don’t have to change your old often

Amsoil is the best full synthetic oil there ever was, buy some.

I love this stuff, Its all I use in my vehicles!

I really feel that amsoil is best oil on the market by far, only company that tests its oil against all their competitors!

Folks, this Synthetic Oil is simply the best manufactured oil money can buy. If you care about protecting your investment, while using the best product in the market, then look no further.

I have not done a legit full break-in for the motor I am rebuilding. Only did 100 miles running time with regular driving using break-in oil for now.

The best synthetics Period,
