I have been using this product since 2017 in my 2015 Camry XSE 2.5L non-hybrid. I do 10k mile oil changes and when I got the car it had 28K miles on it. The car now has 140k miles on it and at 120k I sent in an oil sample to Blackstone Labs, their test stated that I could run the oil at least 10-15k more miles. Although that would save me some money I will continue to change it at 10k miles per the Toyota recommendation. It's a piece of mind knowing that the oil is still in great condition and not at end of life when I change it. I am trying to see if this car can make the 1 million mile club.

I been using this oil on my mini van and do an do the oil change every year and still very slippery so and can leave it for few more months if I wanted

No oil consumption and 25k worth of protection. Buy it and you will never go back to store bought hydrocracked crude oil(Mobil 1, Castrol, PennOil, Valvoline and all the rest....).

I love the oil and there filters 🤪 😌 😍 But there billing department needs work Other then that all good bye it and you will be happy u did

I been using Amsoil for 15 years in multiple brands of cars. Have it currently in four different cars. Every time I've ran the oil to 25 thousand miles and highly exceeded the 700 hours run time. Never had a problem with any car and my current work car (Honda Fit) has 365,000 miles. I've used Amsoil on that motor since new with never any problems. I will recommend this oil to anyone thinking of doing so. Rich

I have always used the signature series and I’m impressed with how well it works and how long it lasts. At first concerned about the extended months but It’s exceptional and far exceeds my expectations!!

Best quality oil available - my vehicles always run noticeably smoother after an oil change. Great product!

Best quality oil in my opinion! I can always feel a difference/My vehicles run smoother after a fresh AMS Oil change..

Been using amsoil oil and filters for 6 yrs now. Great stuff. Truck and car running great

Shipping was fast, engine is running super smooth

Engine runs super smooth after oil change, I love amsoil and the piece of mind that my engine is being lubricated with the best oil out there

This is amazing oil! Plan to use it the life of the engine. This is a like new rebuild.

Amsoil is the best synthetic you can put in your engine hands down! 2014, Camaro, SS, manual, LS3

Typically excellent Amsoil quality. Good, competitive pricing. For the vehicles we have which require a 5W-20 the engines seem to run better than they did with just an oil and filter change to a non Amsoil product.

I use it since I don’t remember when and I don’t worry about my car’s engines at all for a full year. Protection at it’s best. Just try it once…the rest is history.

This oil has made me feel more confident in my truck it runs smoother and it’s a hair quieter I feel like my engine is going to last a lot longer

I've been using AmsOil products for 30 years. It's by far the best synthetic you can buy. They always are improving the products and keeping up with market trends and new technology.

GREAT ,FAST SHIPPING, I mean really fast. 3 days fast. Not just once every order is fast. And if there's a problem it's corrected, usually with no returns or questions.

Use in my 2015 Jeep Grand Cherokee. Engine stays clean inside, and weel protected!

Good oil for 2021 Jeep Gladiator with the Pentastar engine.
