Best oil I’ve found and always fast delivery

I've been using Amsoil for a few years now and like there products. My last shipment arrived with the shipping box half crushed and ripped open. The filters were out of there boxes and dirty, luckily the the oil jug wasn't punctured but crushed some. I'm sure it's most the shipping carrier fault from dropping it at some point. Amsoil could definitely improve there packaging a lot when shipping fairly heavy boxes. My shipment was missing the free rags that was included, im sure when the shipping carrier dropped it and it ripped open that the carrier didn't put them back in the torn up box.

Why mess around with the heart of it all. Your engine will thank you

Best oil in the market! Have used it for years. Will be doing my transmission oil tomorrow. I use Amsoil on all my cars, trucks, lawn mowers, and motorcycles. Made a huge difference on my Harley. Thanks for a good product!

The best oil next time I’ll get the 6x not because this wasn’t perfect but I’m going to tow so even more protection.. This is a perfect application for commuting and doesn’t get any better than Ams Oil .. I did a complete fluid transfusion with all amsoil products ..

Product is a little pricey but it’s well worth the price and have no complaints about product and company

Amsoil has worked Great in my 2018 Ram 1500 3.0 Eco Diesel.

I use AMSOIL oil from 2022, engine run strong, when I do the Oil Change the oil still looks good after 10,000 miles. comparing other brands which after after 7000 miles, I realize and I noticed the oil was low in the engine and when I did Oil Change, the oil was very dirty. I will use some AMSOIL oil and I recommend for family and friends

good product and ship time

Even in South Mississippi Heat, Amsoil keeps my tractor engine cool and quiet. I run Amsoil in EVERYTHING!

Just thebest

Great products and i didn't know that I could join are order stuff for myself. Thought that you had to get it from a dealer.

The best diesel oil there is. Use in my Cat skid steer and soon in my Ford F350 6.7 diesel

Great diesel product

I have been using Amsoil in my trucks for twenty years. I have been very satisfied with the performance of this oil.

While looking for an oil to use for my truck I decided to give AMSOIL a try I must admit the packaging was great and also the product. My ford 350 diesel runs super smooth with this oil as if it’s not even a truck lol. I’m a believer now I’m putting this oil in all of my cars and motorcycles from now on thanks amsoil (btw I never leave reviews for me to do this means I really enjoyed this product)

This is the first time I ever use this product so I will wait and see how it works after I get a test done after my first oil change with this product

It's a great product just disappointed that I could not purchase an oil filter for either my pickup truck or my motorcycle.
