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.

Super easy to order and shipping was fast. A rep even reached out to follow up on my order once I did the oil change. So far 600mi into the change truck is running smooth and has gotten better gas mileage. It's a price jump from regular auto store oils but when you account for longevity of the oil you get way more for your buck.

I've been using this in a ford ranger pickup, and a Chevrolet Impala, the pickup just turned over 200,000 and the Impala just turned 260,000. Enough said.

So far using AMSOIL every truck or car I’ve put it in you can barely hear the engine it’s so smooth. I have a 6.4 hemi And they have a natural loud chirping or squeal noise from the factory. After using AMSOIL mine is now the quietest of anybody I know you can tell a difference in every way. You definitely get what you pay for I will not go back to Conventional oil that would be like putting crushed dinosaur bones comparatively to AMSOIL. I highly recommend this oil and any products this company sells.

I’ve been using amsoil for years what a great product. The truck I’m driving now has over 200,000 miles with no problems. This is my 3rd truck using this oil. I’ll not go back to conventional oil’s. Thanks amsoil for making great products. All the products I use you make has been great.

Great oil. I use this oil and trust it in our vehicles and one of my daughters car. I'm very satisfied with this oil.

Great oil works wonders

Just started using Amsoil and couldn’t be more satisfied. Already getting better fuel mileage and seemingly more responsive engine. Customer for life!

Just love that I can get a great product I can trust!

Been using Amsoil since 1998. I’ve used the oils Amsoil calls for in Vehicle look up. And it matches the manufacturer called for weight. I went to the 5w20 when we bought the 2014 Ram with a HEMI. And my 2016 Jeep Wrangler takes the same weight so I can just buy a case every year. Awesome oil as always.

Been using Amsoil since 1998, and wouldn’t have it any other way. Excellent oil I can trust to do its job, and it does that with flying colors. Been using the 0w40 in my 2015 Challenger SRT392 since new. Awesome oil

Just bought this for a friends new car. He did the research and found that what I had told him was correct, You cant buy a better oil for any vehicle. He was really impressed with the change duration and overall performance. I will use nothing but Amsoil in everything.

Ever since I had a cam installed along with other mods on my LS3, the speed shop doing the work highly recommended Amsoil. So ever since then I’ve been a customer of not only Amsoil oil, but some of their octane booster also. I will continue to purchase Amsoil products from now on. Great stuff for sure.

It's the best motor oil I ever used, I always used Mobil one for the longest time, and than I looked at Amzoil and found that Amzoil was 150 percent better no I've been using Amzoil for about 20 years and won't go back.

Not having to add oil between changes is huge, even when going 20-25k before service. Love this oil!
