Seems to keep the engine quite clean. No issues running 91 on a 2.7 T

Only oil I trust , to hold up to it's viscosity, wonder what's stronger, this, zrod or the dominator racing oil

Will use nothing else but the best!

It hasn't let me down yet. I recommend it to all of my family & friends.

When you use the very best oil it only makes sense to use the very best oil filter. My vehicles are only get the very best it’s worth paying a little more but the outcome saves money because less expensive breakdowns.

Have been using it for years In my Toyota vehicles. Have 442,000 on my 2008 tundra

I’ve used Amsoil for over 30 years. Will not use anything else.

There’s only one oil, Amsoil. I’ve been using Amsoil for over 30 years, will not use anything else. Superior wear protection.

I have been using this oil for a few years and find that it keeps the engine very clean and performs very well. In my onion, I find that this is one of the best oils I have used. I also use Amsoil in my diesel truck.

I use Amsoil in my Dodge Ram 5.7 Hemi 4x4 and both of my Harley Davidson motorcycles and I am impressed with the performances! I switched to Amsoil because I got tired of going to the local auto parts stores and they are usually out of what I use, so I went with Amsoil and it is delivered to my front door, love it!

I have been using Amsoil since I was in my 20’s so for over 20 years now. In my last Cummins I would send samples in and have it tested. Even though at 40k miles it always came back good I could get myself to keep going. So I know for a fact you can go a good 40k. Just change the filter every sample you pull and replace the oil from the filter with new.

I have had many years experience with all your products and have never had an issue. And the service is excellent,never had a problem with any orders, always exactly what i ordered ! What a pleasure.

Have been using Amsoil for the last 20 years..now..in my 2023 GMC Acadia 3.6L engine I am getting 32.7MPG on highway driving and 25 mpg running around town shopping...ETC..i do my own oil changes..and when i change the oil (signature 5w-30) it looks like N E W OIL..!!!!!!!! PLEASE do urself a favor & feed ur engine AMSOIL OIL..!!!!

Wow. I’ve been stuck on not “100%” synthetic with Motorcraft while the car was under warranty and I couldn’t use anything else. Time was up. Switched to Amsoil and headed out on a 800mi road trip. Temp stayed very consistent avg 80+ on the freeway for hours. Drivetrain noise is lower, oil looks like I just added it. I’m SOLD! Wish the USA would get more transparent when it comes to oil quality. This stuff is top notch and I’ll be using it in all my vehicles (and recommending it friends!) moving forward.

Best oil available

I live in a rural area and as a single mom of 3 kids I have to drive a lot. I can easily put 600 - 900 miles on my vehicle in just 7 days!! I use synthetic oil in all of my vehicles and will have to change my oil every 4-5 weeks with regular synthetic oil….so it just makes sense for me to use ALL amsoil products as they don’t have to be changed as often plus they really do help your vehicle perform better. I just recently switched my daily car to this oil and almost immediately I noticed my car ran so much better and even gets better gas mileage. I will be switching my other 2 vehicles to amsoil on their next oil change.

Since day one, my 2023 Explorer ST TT has used this oil; I changed the engine oil at 10 miles on odometer. Never has issues at 10,000 mile oil changes and can tell a slight difference with Engine temps and performance as a daily driver. I also tow a lawncare with this; my lawncare equipment also uses Amsoil

I've been using Amsoil since the early ' 80s. Always inpressed with its anti- wear performance and long drain capabilities. Outstanding!!

AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil,,,great product and great price

I've been using Amsoil on my 6th Gen ZL1 since I got it and have never had any issues. Oil pressure is higher than oem oil. Would recommend.
