Customer Ratings & Reviews

I use AMSOIL products in every one of my vehicles. Best product on the market.

Best performance and durability

A money saver with extended drain. Great protection from friction and heat.

My wifes car runs so much smoother. I love that it's 100% synthetic and I don't have to change her oil every 5k miles. Eben is the reason I switched to AMSOIL.

This is by far the best oil I have ever used! Have used Mobil One but for roughly the same price you get a much better overall performance product with Amsoil. Every 5K miles I change my oil so for me it’s roughly 2 changes a year so the confidence of knowing I have an amazing oil plus the protection of Amsoil makes me happy!!

Engine is running so much smoother after swapping.

your products are of very good quality. I hope you give discounts to your customers. )

I decided to make the switch to Amsoil. So far, so good. No consumption, burning or puffs of blue smoke on cold starts.

Use it in a vehicle that only gets driven about 4000 miles a year. It gets changed once a year and used oil comes out clean. Want a superior oil for these reasons and the Signature oil fulfills my needs.

Went from using Mobil 1 to Amsoil Sig Series Full Synthetic 5-30 years ago. Even though Corvettes recommend Mobil 1. My Vette runs cooler and quieter with Amsoil. I have tracked the Vette and it performed excellent. I switched both my daily drivers to Amsoil as well. Have also convinced other Vette owners to switch to Amsoil. They have all become regular users as well.

Definitely ordering it again

I've been using Amsoil in my wife's car since she bought it brand new. I would use nothing less!!

Been using Amsoil for the last 20 years and every car I have used it in never burned oil and and never leaked. And I keep my cars for a long time most of them have 200,000 miles. Will always use Amsoil no matter how the manufacturers try to bad mouth it or try to get me to use their oil. Had a few cars where the manufacturer had recalls on oil burning and none of my cars burned oil using Amsoil. Maybe the car manufacturers should start recommending Amsoil lol.

Using Amsoil is equivalent to eating the right food. Don't use cheap products in your vehicle. Protect the life of the engine with the best lubricants.

Have a 2009 Volvo and have used Amsoil for the last 120,000 miles. Currently I have 211,000 miles on my vehicle and runs as smooth as a new car! I have used Mobile 1 in past before I switched to Amsoil. There definitely a difference in how smooth and quiet my engine runs. Mobile 1 is good but Amsoil is definitely a step above and worth the extra $ u pay to have your engine run at peak performance

I tow a 30’ travel trailer and wouldn’t trust any other oil for my vehicle. It’s lab proven.

I recently switched to AMSOIL in my 2022 Honda Civic Si. I plan to push this car hard on the track and needed a synthetic motor oil that could handle it and keep my engine in top shape.

I have been using amsoil for 20 years. My engines out last the rest of the car literally! All vehicles had over 250k+ miles. Love this stuff with up to a year between oil changes and you can also add a couple MPG beyond what the MFG states, which was my experience.

Excellent. I change oil every 5,000 miles. I was using Mobile 1.

great items, I have been using these products for quite some time now and have never had any issues. definitely recommend their products to everyone who is on the market for great motor oil and additives
