Customer Ratings & Reviews

AMSOIL in all my vehicles, gas and diesel saves me money and time, because of the extended drain/change intervals.

Very good quality and easy to poor oil. Love to do my own oil change.

It has out perform the other oils I have used in the past

Upon first pour, the signature oil presents a luminous chartreuse hue with golden undertones — a color that speaks not merely of ripeness, but of restraint and patience in the lab. The aroma unfurls slowly: an elegant bouquet of freshly cut grass, green almond, and the faintest whisper of artichoke heart, balanced by a flirtatious hint of sun-warmed citrus peel. On the palate, the texture is nothing short of symphonic — silken yet assertive. A bright, peppery crescendo arrives mid-taste, recalling Tuscan hillsides kissed by late autumn light. There is depth here — an oil of character and confidence, unafraid to linger, leaving a gentle bitterness that cleanses rather than overwhelms. A Gen V engine jumps with joy when lathered up with this oil from the angels. One might say it’s less an ingredient and more a conversation — one between land, sun, and centuries of patient cultivation. Best enjoyed with nothing more than a crust of artisan bread and the quiet satisfaction of knowing you’ve chosen correctly.

I have been using Amsoil in a 2023 Taos since new. The manual says 1 qt/2000 miles oil consumption is "normal". That isn't normal to me. That Taos has not leaked or consumed oil that I have even needed to add a little to get it back to normal fill level, it has needed ZERO oil. I trust Amsoil and my trust is proven by no oil consumption, and backed with used oil analysis, that shows it holds viscosity, prevents oxidation, and has plenty of additives when time for a change. My wear metals are extremely low, which is really good for a low-tension ring, small turbo DI engine that is under a lot of stress and heat in it's normal operation. I will continue to use Amsoil in all my engines.

Been using Amsoil products for over 20 years, and they are the best in my opinion. Have never had an Engine Oil related issue since using Amsoil products.

I have a F150 and have been using this oil since new. The 3.5L Ecoboost loves this oil, and I have had zero issues with this engine. Poor quality oil and extended mileage between oil changes will kill these engines cam phasers. Never a problem.

Have used Amsoil in all my vehicles for over 20 years. Swear by it.

I do a 22k oil change, and it lasts till the end like new.

Great product helped with my Toyota Highlander death rattle at ignition. Would definitely purchase again for my next oil change. Also used the Amsoil filter

Use in my 3 vehicles for the best protection have a lot of faith in this product

Been running the soil and eco-boost engines since 2016. 2.0, 2.7 & 3.5 L in five different vehicles between my son and I. Also, in a Lexus LS series. Total mileage well over 200 K.

Drained old oil and changed the filter without any problem. I hope the oil lives up as advertised

Best stuff on the market. I have a 2019 4Runner, which can be a noisy engine. After using signature series, my engine is quieter with better mpg. Make sure to change your other fluids as well. Less friction equals better mpg

I trust AMZOIL above all others in providing a top quality product!!!

Excellent oil surpasses my expectations

Awesome!! Product is great saving on gas mileage already thanks..👍🏾

I just put Amsoil Signature Series in my 2019 Ford F150 5.0 KR for the first time and seems to be running smoother and I believe my MPG is a little better. I have the gear oil being shipped now for my differential.

I been using this on my 23 tlx and my scat pack also on my nissan Great oil Great stuff 👌
