I purchased this product because my hubby, who is now in heaven, used it. He believed in using synthetic oil for our vehicles because synthetic oil is better for the engine. I haven't used the new shipment yet, but I will when it is time to change the oil.

We own a 2008 Corolla ,which requires 5w-30. We were running a leading Synthetic oil which rattled on start up ,until the lifters pumped up. As soon as we changed to AMSOIL all the cold start rattle stopped. I have a history of AMSOIL in all my cars and this has always been my oil of choice!

I have used this oil anytime I could

Great Product: I have used this Product and have noticed that my car seems to run smoother than before.

Used Amsoil scene 1974 I drive millions of miles abd never lost anything lubricated with Amsoil

Doesn’t matter what ICE you have, Amsoil is the best. Contains more anti wear additive package, TBN, film strength, and resistance to heat induced breakdown of any other oil. Oh also cold flow stability, no other oil of the same weight flows as well as Amsoil.

Independent testing and laboratory independent testing both confirm by a measurable margin amsoil is in fact the best oil on the market. It is not snake oil it’s truly the best at film strength, anti-wear additive package, total base and TBN anti-acidification properties are superior than any other brand yes including the purple bottle.

Only oil I use in my 06 h3 and she still runs like new!

Best oil out there by far!

Outstanding product, protects moving parts as advertised, never had any issues using this product. Beside that always had excellent service from my distributor and Amsoil.

The 5W-30 signature series is a great oil for my HVAC work van. Chevys need all the help they can get to keep the lifters from ticking. The AMSOIL does the trick.

After waiting two years to take delivery of this new Bronco . I could only seriously consider using the best synthetic oil on the market. With wear and heat protection needed for the twin turbo motor is a must; especially in central Florida's warm and humid climate.

I have always run AMZOIL in my vehicles and have found that they seem to rev smoothly and effortless, keep engine cleaner, and definitely improves fuel economy. Been using it since 1981

Cost more than the other brands but we'll worth it. Especially if you are keeping your vehicle(s) for many years

WHEN I CHANGED THIS IN MY JEEP MY MPG WENT UP 2 MILES PER GALLON

It does everything I want and more ! Nice to have such good protection that you don't have to worry if you go a bit over on changes !

Have been using Amsoil for 40+ years always my first choice.

Quality product.. use in 3 vehicles

Great oil, Jeep runs a little cooler than the original conventional oil came with.

Good oil good service. Would be nice if you just included funnels with each oil purchase. For what people pay for oil, it would be a great item to just give to customers. They are almost always necessary
