Got better horse power and got an extra 2 mpg

At times i've pushed my oil to the limit and it still held up and at times i've pushed my oil past the limit and it still did it's job. you can't get a better motor oil for any situation.Great oil pressure all the time even when the oil has high milage on it.I use 5W/30 signature for 8 years now in my Toyota sequoia witch i bought used and it does not use a drop of oil. my Suv is an 05 sequoia with 140,000 and it runs brand new. thank you Amsoil for a superior product.You will always have a life time customer.

Great oil running good and smooth through my 06 Cadillac sts!

Been using Amsoil products for 30 years never a failure.

After a tons of 5 stars reviews of this oil, I decided to start using it. So far the car feels more quiet, smooth and responsive. I feel more confident in my brand new SUV with Amsoil on it. So far very Happy. I recommend it.

Have used AMSOIL for years on many personal performance vehicles. Purchased a new RAM TRX and like my other vehicles use only AMSOIL. I have had my oil analyzed on all my vehicles with impressive results. AMSOIL is a proven product and you won't find a better performance oil for any engine application.

Only have about 200 miles on the AMSOIL but I did a lot of reading up on this product it is a little pricey but I’m running it in my 2024 mustang gt so I wanted to go with the best possible oil I could run

can’t believe it. I noticed the car is now getting 3 to 5 more miles per gallon. I try to think it couldn’t be the oil but yes, it absolutely is the oil. This is the first long trip on this oil after changed. I am happy.

Travel 55k miles per year and have used Amsoil motor oil in 10 new vehicles in last 20 years with mileages over 260k miles. Very dependable with not engine problems.

Was sold on it when we changed over to synthetic oil in vehicle and it almost stopped using oil

I’ve been using Amsoil for around 15yrs, never had any engine issues on any vehicle I’ve driven and owned.

Best stuff ever have been using Mobil one and usually zmax and hyper lube additives and just this oil alone just like they say greatly surpasses anything available out there my engine has 237,000 miles and really eats and blackens oil but with amsoil it really handles how they say I feel in love and almost no dry start whatsoever love this oil will never go back

Wonderful products. All of the products came with great directions for use and works like it should

Switched to AMS Oil from Royal Purple for my 2010 Camaro SS and so far the car is running better than ever. Very happy with the switch.

This stuff is superior. Highly suggest spending extra and picking this up over any other product. I even gained 1.5 mpg from my 17 tacoma trd offroad. Spend a little extra now to save lack of maintenance repairs later, just my word of advice.

I am a first time user . Heard very good things about AMSOIL . Just performed my first oil change on my Ram Power Wagon

Simply the best motor oil I've used. Whether in arctic (0W-30) or subtropical (10W-30) conditions, this oil has never let me down.

Love Amsoil Products been using it for 30+ years

I have been using Amsoil for years in all of my vehicles and my families vehicles, excellent product, my father uses this specific oil in his hemi ram and he has lost the hemi tick on the lifters, I will always use asmoil in everything from lawn mowers to trucks

This product is top notch. Seems like the engine runs a bit smoother, and oil doesn’t darken up as quickly as other name brand oil. Definitely a repeat customer here!!
