Customer Ratings & Reviews

It's the only choice I make for my truck. Only down side is that not many local stores carry amsoil so to buy a top up litre is hard to find. I just buy one extra.

One vehicle I have is a 1988 Bronco II 2.9 engine 5speed. I have all Amsoil lubricants installed in it. THE ENGINE REALLY LOVES THE 5W30 Signature series oil.The Amsoil fluids really make a difference.Thanks Paul

Are used to use Pennzoil 1030 all the time aside to switch synthetic when I bought a new her car with low mileage and I use synthetic and all mine your engines and I like the amzoil product so far no problems

I love this product it make what suppose to do and long life

I use amsoil because of the superior protection and longer change intervals this product has been the best oil I have ever purchased and used for my truck boat and even my lawnmower

Have switched to amsoil on our vehicles. Love the 15k mile change interval.

Best investment for any vehicle long term, 25,000-mile intervals for oil and filter. You save so much and the quality of the oil is far better than all I've tried!!!

By using amsoil it is saving money in the long run {less oil changes every year]ect. ]

Great product to maintain my daily driver

I'm a new user of AMS products but am impressed with the ratings.

I'm a car guy. I've used all the top name brands u can think of, but no oil has ever given me 20k+ miles on a single oil change, and I drive my cars hard. I've done and undone engines with friends and never seen cleaner internals with Amsoil in it. I'm a forever Amsoil Customer!

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.
