Truck runs great with this oil, works just as expected.

Great oil at a resonble price. Have used amsoil for years in all my vehicles. Good delivery times. Will continue to use for many more years I'm sure

Along with the amsoil filters of oil consumption with my fleet has more than cut in half

I run Amsoil in everything I own

Great oil I don't care what anybody says oil is not just oil won't use anything else but this

Best oil on the market! Been using Amsoil for over 10 yrs now. No complaints from me.

Increased mileage per gallon from 45 to 47. Will be able to run extended distance. My only “complaint” filters were not available at time of purchase of oil.

Bought this for my Ram TRX.. Wanted the best lubrication for this beast of a truck!!

I wouldn’t use any other oil than amsoil!

This is just my opinion but I think AMSOIL is the best synthetic oil on the market. Worth the money to me

I 100% recommend this best oil you van buy

I replaced it due to low oil pressure. I will continue to use this oil in my diesel and with more research may be my boat

The best!

Excellent oil! Keeping my Hyundai Santa Fe running like new with 273 000 klms on my 2.4 L GDI motor. The inside of the motor is spotless!

This is the best oil ever! I have been using it for 7 years and ad it protects my engine best.

Amsoil is without a doubt the best oil money can buy. Project farm on YouTube did the most in depth review/comparison I’ve ever seen and amsoil came out on top. For long term engine protection, it simply doesn’t get any better than Amsoil signature series.

I use this product for my RAV4 2020 LE my car run smoothly and the the winter I'm using the same product thie the summer see what happens

The only oil I run in all of my vehicles

Best motor oil available

✔ Started using it in my 1999 Ford Ranger – Engine lasted 300,000 miles, immaculate condition. ✔ Chassis rusted out, but the engine? Flawless. That tells you all you need to know. ✔ Now using Signature Series in my 2025 Ford Maverick 2.0L EcoBoost – Switched at 500 miles right after break-in. ✔ Turbocharged engines need the best protection – AMSOIL lowers temps, reduces bearing friction, and maximizes longevity. ✔ Plan: 8,000-9,000 mile intervals with annual oil testing to monitor engine health. 🔹 Final Verdict: If you own a turbocharged engine, this is the oil you want. It’s not just marketing—it actually delivers better wear protection, stability, and performance under extreme conditions. Simply the best.
