If you read my other review for the European motor oil, I mentioned that I had also purchased motor oil for my truck. I believe that AMSoil Signature Series motor oil is either better than or on par with the best motor oils in the market, including German made Liqui-Moly. For any given viscosity requirements, if the selection includes Signature Series, I will always opt for this more expensive oil instead of the less expensive AMSoil OE series.

This is the only motor oil I’ll run in my vehicles. I’m a big believer in getting what you pay for, and while it’s a tad more expensive than big box oils, you can’t put a price on the piece of mind knowing that you’re running the very best oil in your engine. Worth every penny!

Best synthetic for 6.2 performance.

Great oil and easy to ordering.

Great Product for the price

work well

When it comes to synthetic oil, look no further Amsoil is top-notch. If you’re looking for quality, fast shipping, and outstanding customer service I would definitely recommend Amsoil. Thank you, Amsoil!

I won't use anything else in my vehicles. Signature series is by Far the best Motor oil I have used.

Very good product,will purchase again along with radiator coolant...thanks

Have used Amsoil Signature oil and Amsoil products in all my vehicles for 14 years, nothing better!

Have been using this oil in my wife's Ford escape Ecoboost engine since new and are now at over a hundred thousand miles with zero issues! No junkie build up and I change between 12 and 15 thousand miles.

I swear by amsoil products..i use them in everything i own..even when due for oil change it still looks clean..the extra money now saves big time later

started using Amsoil on my last oil changes and have had no problems at all!!

I've never had any issues with AMSOIL products. I love their oils and purchase them regularly.

My top off when low . Since these Hemi ‘s run hot. But with ‘‘this oil cooler temps.

I wanted to try something new other than the other engine oil company’s . I am very happy with the results I have been seeing and will definitely recommend to anyone that’s wants a change

Experimenting with Amsoil motor oil, we'll see if it's worth all the hype

I use it to ease my 5-50 sig.tuned 2.0t Audi into cold weather.love the gallon jugs.

I use it on a 19 ram 24 caddy and 08 corvette altogether about 23 qts so the gallons are more economical and less confusing.I also cut my oil filters for inspecting.

2012 Ram 1500 Crew Cab that developed the infamous tick. I started using Amsoil in early 2024 and within two oil changes the tick was greatly reduced. It is not a fix by any means, but goes to show what a high quality oil can do for the engine in protecting it.
