I’ve been running Amsoil in my motorcycle and cars for years. I trust their products. This signature series seems like the ultimate oil. Highly recommended.

I run 5w30 signature series in my 2021 F-150 3.5 Eco Boost engine. This engine has twin turbos and they run extremely hot. I feel Amsoil gives the protection needed to reduce engine and turbo wear. Phil

I have been using Amsoil in my Subarus for over a 15 yrs. I usually run 18-20k filter every 5k before changing. I have never had any issues ever. Best there is

The large oil jug is a convenient size and bit more economical. I will only use Amsoil in my high meager Tundra

Always use Amsoil. Especially with many vehicles

Great product would recommend it to everyone

I have a high flow oil pump installed in my motor, oil pressure runs mid 50 psi and consumption hasn't been a problem yet. I believe amsoil is the result of the steabyness i was looking for.

Love the oil not so much the filter.I really wish you guys would get the amsoil ea17 filter back in stock, its been far to long they've been on back order.

I have used this product in my 2000 Camry since 2004 (odometer: 71,000) until the present time (odometer 328,000 +) and in my 2006 Camry since May, 2025. I don't think that there is a better oil made! (By the way, I usually change the oil filter--I use the WIX oil filters--every 6 months.)

I have done oil samples and after next test it should be a very informative result

From my 67 chevelle to my 2024 GMC Sierra my wife's car and the kids this oil has me covered

I have used it in my f150 with 2.7 got 285000 on my truck with no engine problems what so ever.

I always put Amsoil in all my vehicles and I highly recommend oil the 0/20 signature series is the best on the market never had a problem with any of my vehicles using Amsoil

Iam gone stay a amsiol fan forever

Great oil is the one thing I can rely on when the auto manufacturers keep reducing their oil viscosity to achieve fuel efficiency for some tree hugging politician.

Read all the reviews , watched all the videos, it's the only oil I'll trust in my car

Whether viewed in terms of quiet operation or evaporation loss, it stands alone—no other product can hold a candle to it.

Did a recent oil change in my 2020 Cadillac XT6 and used this oil. The vehicle has alittle over 90k. The oil appears to have quieted down lifter noise and engine runs very smooth.

Its the best syhthetic oil out there

My son's 1991 Miata 1.6L with 190k miles has had a worsening lifter tick since we bought it almost a year ago. I use Amsoil in ALL of my vehicles so in this Miata we use the Mazda rec'd 10w30 Amsoil High Mileage. I trust this oil to protect the engine, even when it's making noise, and even while my son drives "spiritedly" pretty much at all times! We're not ready to build a fresh engine for this car just yet so I decided to try out Signature Series 5w-50 and see if the added viscosity would help quite the lifter tick. I am happy to say that since the first startup after the 5W-50 oil change, we have not heard the lifter tick even once in the last 1000 miles of driving. Yes, it's just a bandaid, but it'll do just fine until we get around to the engine rebuild and a new set of lifters.
