The best you can get!

Fits perfectly with manufacturers requirements

As soon as I was due for my first oil change, I went with trusted Amsoil products. They recommended this weight in my current car. Even in the Texas temperatures this summer, the car has been performing better and better. On my third oil change now. Throttle response and torque feel great. Thanks for another great product! 12 year customer, will continue to use Amsoil signature series in all my vehicles.

I love using Amsoil for its performance in cold weather. Where I work I do not have access to be able to plug in the block heater in the winter. With the Amsoil I have never had an issue starting the car even at -38C after 8 hours at work.

I put a reman engine in my 2009 F150. No issues so far. I like the fact that I feel confident in 10k changes. I have 35K on the reman.

I used to have a rear main seal leak. After hearing the miracles of amsoil I tried it last November and haven’t added a drop of oil for 11 months now.

Love this oil ! I wish I would have found it years ago

Outstanding

Extremely fast shipping and great customer service! They always deliver it fast when I ask for it. And ofcourse great product!

Very pleased with Amsoil 5w-50. It will be the only oil I use in my GT-350!

I wouldn’t think of putting anything other than Amsoil lubricants in any of my vehicles… I use only the best.. you won’t find nothing more better. Amsoil to me is having the peace of mind knowing my vehicle’s have the best of the best. Always 2 thumbs up.

Just used this oil in my 2013 Honda Accord. I could tell right away it sounded smoother than when I was using the other brand. I will definitely be using this for the my vehicle from here moving forward. Also, shipping for me is great as they also ship out of Las Vegas, NV and I'm in LA, CA area. I've received orders no later than 2 days from date of purchase.

I use the Signature Series in my 2014 Corvette. Their are so many discussions on social media with fellow Corvette owner about what is the best oil. Nearly all say that Mobil 1 is the Holy Grail of motor oils. I tell then that their is a difference between Full Synthetic and 100% Synthetic oils, and that they should do the research. That said, oils with no petroleum base stocks are clearly better for our Direct Injection engines. I am sold on Amsoil. Thanks for your great product!

Great oil. It’s such a hassle trying to find 0w40 for my Ram 2500. AMSOIL makes it convenient to order and it’s a great product. My only wish was that AMSOIL would carry WIX XP oil filters for my vehicle.

Well worth it.

Always use Amsoil oils

I run amsoil in every engine I own. Cars, mowers, boats, etc… all I will ever use or recommend. Shipping is fast!

I was very surprise as to my truck responded to this oil. My gas mile went up 3 more miles per gallon -13 to 16 . With an oil additive the miles per gallon increase another point (17.5) . I would definitely recommend this oil . I have a 2005 DODGE RAM 1500 with a 5.7.

Keeps truck running like new

Heard about this being the best, and I think it is. Use this stuff for my 4-wheeler as well. I drive for Lyft and I think AMSOIL has what it takes.
