Customer Ratings & Reviews

Been using Amsoil now for close to 20 years. Been using the Signature Series Products since they came out years back. Since using Amsoil everyone of the fluid levels stay at a consistent level. Still check the levels frequently and they are always at the same level as last checked. I have been in -123 Degrees to +131 Degrees and have seen how cold and heat affect fluids. Here in MIchigan we still get some very cold days and Amsoil still works great. No matter the driving conditions or weather it is nice to know having Amsoil fluids in my Engine that the Engine will be at it's best.

Seems to be fine. Won't know until I do oil change. BUT, the 1 gallon jugs need a design change or a screw on funnel with them. Even with the funnel I have used for 20 years to do oil changes it still glugged out past the funnel or down the side of the bottle. Have not had the problem with 5 quart Royal Purple or any other 1 gallon jug in the past. Just my thoughts.

Been using this oil in my jeep wrangler after getting noise from engine has gone away.

I recently had a conversation with my son about AMSOIL 5W-30 motor oil, and I must say, I’m impressed with the information he shared. He highlighted the oil’s exceptional lubricating properties, which provide excellent protection for the engine and reduce wear. Additionally, he mentioned its extended drain interval capability, which can save us time and money on frequent oil changes.

AMSOIL makes the best oil on the market. When I use this oil, my vehicles run good. I change my oil every 3,000 miles which may be an overkill. But I have to be careful with my cars. My 97 cavalier has over 300,500 miles, my 06 mustang gt has over 276,000 miles, and my 06 tundra has over 207,000 miles. I want my vehicles to last as long as possible, before I absolutely have to buy another car.

I just changed oil. I'm sure this product will be as good as the other products amsoil sells

Great doing business with these people never had a problem always quick service. It may be a little more expensive but you pay for what you get.

Great trusting products, huge fan , been a Amsoil customer for years on all my cars, trucks, compressor, and mower.

I've been using this Oil for 20 plus years now. Pil holds up very good in my 1.8 liter motor. I plan to drive my Vehicle for another few hundred thousand miles and with the likes of Amsoil.

In my opinion Amsoil is the best oil on the market I run it in every vehicle I own and side by side

Seems to work very well. Running the oil in both of my vehicles.

If you want your engine to run at its best amsoil is the only way to go. Fuel economy and performance will be the highest you have seen.

My first order went fairly smooth there was a hiccup but once I called it was taken care of right away! The oil is spectacular it works awesome in my brand new 2022 Shaker Dodge Challenger. Thanks for a great experience. I will be placing more orders very soon for my other vehicles.

I had been a Mobil 1 user for 10 to 15 years, but when I did did the research it was a no brainer as to which oil I’d use for my vehicles. If you’re in the market for a synthetic oil Amsoil 100% synthetic is the way to go. They do the testing and stand by their products. Amsoil is an American company making US made products. That alone would be reason enough to consider buying their oil. Being the best is what makes them stand out. I’ll be using Amsoil oils, lubricants and metal protectors exclusively on any car I own.

I I have to say about amsoil is it’s the best oil I have ever used.

I have been using amsoil on my last 2 car

I have been using this oil since day one with my wife's hyundia kona . I like the way it runs and she purrs like a kitten. getting great gas milage and starts up with no valve clatter.[

Very good oil highly recommended..... Amsoil needs to step up and change the formula make it stronger, Honda and Toyota oil are caching up ... especially on the lower viscosity.

Excellent quality oil. Engine quiet, smooth. Long distance.
