Customer Ratings & Reviews

I use this in every gas vehicle engine I own(5). I change it every 5k with and Amsoil filter & never a mechanical problem.

Works great

Arrived on time, works like it should have no complains.

Just started using in my Toyota Tacoma (very happy) I finally came around on my every day truck and soon my wife's car. I always use Amsoil Z-rod in my old Corvette and think I will be all set now will my oil changes.

On my third oil change since dealer oil change ran out. So far oil still looks good when changing at7500 miles. Light duty and light towing. Mainly highway miles minimal idling.

I started using this oil when my 2016 Silverado was 2 years old. I immediately noticed a difference in how the engine ran. Now, 8 years later it runs as well as the day I bought it

Works great in my 2024 6.4 hemi dodge ram 2500 4x4

When you use the best,your results are the best

1996 Tacoma V6 3.4 4x4, Truck is now 30yrs old and I’ve owned it 6yrs and from day one I switched it over to Amsoil full synthetic. Truck has 292k miles and still runs strong.

This oil is excellent—high efficiency and performance. I recommend it 100%.

Amsoil provides great quality products, always recommend !

Great oil! Great service! I can always depend on the delivery to be quick and accurate.

I've been using amsoil for a couple years now. After I blew my original motor in my 2013 Dodge Ram 1500 Sport pickup. I purchased a new motor and began using Amsoil because the shop that I took my truck to for the removal and installation of new engine provided Amsoil so I said let's use the Amsoil it reminded me of home. Quite honestly watching John Gillespie fishing show is what got me interested in Amsoil he was always promoting Amsoil on his fishing show. Anywho I now reside in Tower minnesota. I'm on my fourth oil change of Amsoil oil synthetic 5w-30. The first couple of oil changes was with a 5000 mile synthetic oil. The last two oil changes have been with 25,000 Mi 5W30 oil synthetic. Honestly I change the oil at 10,000 a little over 10,000. I've noticed a little bit better fuel mileage but definitely more power in my motor so much smoother after an oil change. I will continue to use Amsoil for the life of this motor. Thank you Amsoil for a great product. Sincerely Joey Johnson

Just started using this oil in my 19 Silverado. Hope to beat the AFM that ruins one of the best engines made.

I have 2 vehicle that I use Amsoil Signature Series 0W-20. One has 216k and the other 105k and neither have had any engine issues. I guess the proof shows for itself. No plans on changing.

I have been using Amsoil oil, filters, engine flush, grease, and other products for many years. I have been extremely satisfied with their products and highly recommend them. The only issue I have had and it is recent, they have been out of their Amsoil oil filters for both of my vehicles. They offer the standard Wix filter but I am buying the Wix XP now from Amazon.

I've been hoping for this viscosity for a year or two and you delivered. But a moonshiner would be shot if he sold his corn liquor in quart jugs. (If there is such a critter). This product in warmer climates should be a good to great seller. Maybe cooler areas too? Anyway Amsoil needs to get this into a gallon jug so I can stop storing my drain oil in milk jugs. (Cleaned out of course)

Top quality product

Keeps turbo quiet runs smooth

I’ve just recently started a job as a medical courier. I was unaware of the amount of miles that I would be putting on my truck. I’ve used AMSOIL in the past but now realize that I need the best oil $$ can buy to care for my truck. Every thing I’ve read about AMSOIL from independent testing says that they are the best and truly a full synthetic oil. Pennsoil ultimate would be second. All the rest Mobil 1, Castro and valvoline are just marketing.
