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!!

First time user of AMSOIL and I won’t use anything else. I’ve had engine knockinf/pinging in my Wrangler JL 4 cyl turbo since I bought it in 2019. The dealer said “it’s just the sound of the turbo 4 cyl engine.” After trying several different brands of synthetic, none ever made it better. But after the first oil change with AMSOIL, the noise is basically non-existent! Anyone with a JL turbo 4 cyl should use AMSOIL signature series. I assure you your Jeep will not sound the same.

Lasted 30 k with no problems.

I being using this oil since 1993 and won`t change it for nothing else!!!!!

I’ve been using Amsoil since 1996. It’s the best oil I have ever used. I actually get a couple more miles per gallon fuel economy plus I don’t have to change oil nearly as quick.By getting longer life out of Amsoil it’s no more expensive than using oil you have to change every 3-5,000 miles. I go 24,000 miles and use 2 filters in a complete cycle. The oil keeps my motor clean and efficient. This oil is the Best of the Best

I love Amsoil, been using their oils since 1998. From my first oil change in my 2015 Challenger SRT392, I have been using Signature 0w40. Car runs smooth and quiet. MDS works perfectly, and I don’t ever worry about the job the oil is doing protecting my Big 392 HEMI. Can’t go wrong using any Amsoil product. I’m a customer for life.

Just love Amsoil! Been using their oil since 1998 without fail. I’m running this 0w30 in my 2014 HEMI Ram 1500 and in my 2016 Jeep Wrangler with the 3.6. I know I know, both call for 0w20. I say Bull on that. MDS runs perfectly in the HEMI and the Jeep can also benefit from that little bit more weight in the HOT Summer of Arizona. I’m a Amsoil customer for life.

amazing product. I’ve been using this for two vehicles that are Mercedes-Benz definitely can feel the performance and the reliability. Every time I drive I don’t feel afraid running my engine too hard, because I know the oil is the best specially from Project Farms who recommends your product from YouTube not even sponsored I wish he could be.

Will forever be a fan

I felt after a few days a significant change in the morning of how it started ! Faster circulation less high
