Customer Ratings & Reviews

Amsoil products have exceeded my expectations, this is truly high quality engine oil i can trust for myself, and my customers, i am a very picky technician and i expect nothing but the best for my shop & clients! Amsoil products is #1 in my books!

I have used this in every Toyota I've ever owned and have almost 300,000 miles on one of them, and you'd barely know thanks to Amsoil. Really superior engine lubrication and protection for long term engine life.

I Have been using this in all of my vehicles for 2 decades now and still nothing else beats it. Period. Even with 25,000 miles annual commute, Amsoil shrugs it off. I really miss Amsoil filters though. They were fantastic too!

This oil is amazing I have noticed lower operating temperature and slightly better fuel economy, I have used other Amsoil products and am very impressed with them all

A+ product

At first I was a little skeptical about going from 5W-30 to 5W-50. I'm glad I did, my truck seems to run better especially during the very hot days we have here in Florida. 96 degrees with the heat index 130 and 100% humidity! Pizza oven temperatures with a dash of moisture. After reading several articles and watching some videos from people who did the same, my engine runs quieter on these hot humid days in paradise where the summer never ends.

Perfect oil. Last for a long time. This oil will last through two filter changes and still provide protection.

Quality oil that's a necessity with thinner oils.

Amsoil is the only oil I use on my Challenger rt. It's a little expensive, but worth every cent.

Never had a problem with my Motors running Amsoil.

Gives my V10 the lubrication it needs to provide HP & Torque to tow the 5-tons it's designed to.

I consider AMSOIL Signature Series oil to be the best synthetic oil on the market.

Made the motor seem a little more noisy then with the factory oil in it since I got it but no issues other then a louder motor noise. Jeep FCA said it's normal and nothing to worry about

Excellent product and these guys don’t mess around they ship FAST

Always, always here in 2 days. Exactly what I ordered. Can’t ask for more.

Good stuff, wish I could have got the oil filter from you but was out of stock. Had to get filters from NAPA platinum filter for synthetic oil.

Great product

Very good

Ive trusted this oil for many years now and its never let me down ,I wont trust another brand in my Jeep

In my book proper engine oil is a must these days, under hood and engine temps are hotter due to emission reasons. Cold startup also a factor for wear. I’m a firm believer that oil (good) oil is cheap insurance and peace of mind knowing that it will protect my engines for whatever demand I put on them. Keep up the good work !!!
