Great for every engine! handles the cold when at -25° Handles the heat when it’s 90° Driven hard at the sand dunes. Never has a burnt oil smell during changes. 180k miles engine is very clean internally.

Keep your engine running like new. I won't use anything else.

BEST motor oil ever used. Best protection, smoother operation and idle. Stays cleaner for longer milage (2500 miles and oil still looks new). I use to be a big fan of the other good oil with a funny color, but Amsoil seems better. If you want great protection, Amsoil is the one for you.

Same review as my oil filters. Will not use any others.

Arrived early, seems to be working well although I recently switched to this brand.

I have used amsoil for many years and have never had a problem. It just extends the life of an engine better than any other oil I have ever used

Amsoil had been the best oil that I've been using for years. It started with one vehicle. Eventually put Amsoil oil in all cars. This oil has helped keep engines running cooler, fuel efficient and more.

I am confident that Amsoil synthetic is a superior lubricant and have been relying on it for years.

Have used in my vehicles for over 15 years. The best!

No issues whatsoever the synthetic premier blend works terrific on our WRX

I’ve been using this signature synthetic annual or 25k mimes oil change since 2012 on my two Subaru’s and I love it I think it’s the best never had any issues with my car and it’s noticeably smoother with this oil. I will never use another brand as long as this is available.

I use AMSOIL in everything that has an engine. The best true synthetic oil on the market

An Amsoil customer since the mid seventies. I never switched for a reason; it's the best lubricant money can buy. My power equipment is subjected to extreme conditions of heat, dust, and hard work, and Amsoil has never cost me a minute of down time. You get what you pay for.

this is great oil for my motorhome

I've been using this in my 2014 Ram since new - right after the initial break-in oil was done. Engine runs perfect. No issues. Hoping to see many more thousand miles in this one using this oil.

i have purchased amsoil products for many years and has never disappointed. Quality product made for the picky gearhead.

Worth the extra $$$. My car feels and sounds healthier on startup and throughout the daily commute and the occasional weekend drive. Will continue to use this product

I went 7000 miles using 5w-30 Signature Series an EA filter. When I changed my oil I took a sample and sent it to Blackstone Labs, and the results were amazing, especially for a 123k mile car. They even recommended me to extend my oil change interval out to 9000 miles.

Save money, when topping off your oil change with this product, than buying by the quarts.
