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 !!!

Perfect oil for daily service in my turbo sports sedan for summer time.

Been running in my 2026 GMC 2500 HD and am getting almost 2 miles more per gallon @ 500 miles after the oil change

Consistent quality time after time. Fantastic customer service and always introducing new products. Been using AMSOIL in all my cars and motorcycles for years. Keep up the good work.

I put Amsoil Signature in a 2022 Toyota Corolla for a couple reasons. If I have to use thin 0w-16, it will be the best engineered oil I can find, and last through the Summer heat, and subzero Winter starts. I believe the specs show Amsoil is going to do the best job , and with enough volume purchased the pricing isn't much more than other oils. I run it in all my cars.
