Customer Ratings & Reviews

Not only do I believe Amsoil extends the life of my vehicles, the extended service intervals keep them out of the shop and me off my back for longer periods of time. When you commute long distances, like me, 3000 miles comes Way too quickly.

I use it in my vehicles. I like not having to change my oil every 3000 miles. I have had great luck with this oil. I will continue to use this oil.

I have been using AMSOIL since the early 1990's. Need I say more?

Great product

Everything about this oil is great. I drive a 98 Toyota Camry that contains an engine toyota was sued over for its ability to make slude and lead to engine failure. Amsoil does not recommend using the extended drain interval (15,000 or 1Yr) with this engine however I only change the oil twice a yr putting on at least 7,000 miles per oil change. I had a 97 Toyota Camry with 280,000 miles with the same engine and the only thing that killed it was a car wreck. My current 98 only has about 140,000 and I expect it will last every bit of the 280,000 and beyond.

Use it in my 2 vehicles, lawn mower. Great staff, only Amsoil!

I had my 1964 Corvette project car all greased and lubed when I learned of Amsoil and then drained and replaced the oils and re-greased everything!

Using AMSOIL with their filter protects my car up to 10,000 miles and still tests good.

Using Signature Series 0W-30 AZO keeps my ordering simple. At one time I was using 5W-30, 10W-30, 10W-40, 5W-40 European Amsoil products. There was a time in the past years that the "Look Up A Vehicle" applications commonly listed the AZO as the first listed oil as the top recommendation. After comparing specs I concluded that the vehicles using the 40 weight products didn't really need that viscosity per the owners manual and the other 30 weight oils could all be well serviced by the 0W-30 Signature Series. It is a great product and I use it in all the vehicles I own and the family vehicles I service.

I've used Amsoil Signature Series 5W-30 for years and will continue to do for years to come. I first started using it simple as an avoidance to constant oil changes. Putting around 25-30,000 miles a year, it made more sense to change the oil once and the filter every six months, rather than wasting time changing conventional oil at every 3,000 miles. Many told me it wasn't safe to do so; however, I've never had any issues doing this. First car...1993 Chevy Corsica 3.1L V6. 236,000 miles when traded. Engine ran perfect, car body rusting out. Next car...1998 Subaru Outback 2.5L 4 cylinder. 263,000 miles before the body rusted apart. Currently using in 2004 Subaru Outback 2.5 around 180,000 and Dodge Ram 2500 5.7 Hemi 130,000 miles. As you see, long engine life with minimal time required for oil maintenance/changing, not engine issues, various engine sizes. All of these vehicles have their oils changed once a year. Filters changed at oil change, and then again at six months. Strongly recommend, especially if you like the simplicity of changing the oil only once a year or put many miles on each year.

I have been purchasing Amsoil products for about fopur years now, everything I own that has a motor and transmission contains Amsoil products. Great products and a great price form a great company. Will always buy my supplies here.

I've been useing amsoil oils for 20 years I wouldn't use another brand if I was stuck out of oil somewhere

Wouldn't use anything else in my new Focus RS! I run Amsoil in all my toys! Cars, Ducati's, and waverunner!

Instead of changing oil and filter 3 times a year on my wife's 2010 Impala, I just change it once. And I am using a better quality oil and filter, when I use Amsoil !!! thanks

Use this oil in a Ford Raptor that travels cross country. I trust this lub for high mileage protection.

Fast service, knowledgeable about product, fast shipping.

Yes I would buy again been using this product for years about 20 years

I use thus product in my recently purchased truck. Mileage got better and engine ran smoother. I love it. I have been this product in mg last three used vehicles with outstanding results.

Oil change intervals last more than six months. I prefer AMSOil 5w30 Synthetic Motor Oil over any other. "True Synthetic."

I run this oil in my truck and car. I swear by it!
