Customer Ratings & Reviews

I bought a 2014 Toyota Sienna new in May of '14. The manufacturers recommended oil is 0W-20. I've used AMSOIL for ALL the oil changes that van has needed. Right now, it has 111,000 miles on it and the engine purrs like it did when new. I've replaced the oil filter every 5000 miles and replaced the oil every 10,000. I've used AMSOIL in several vehicles I've owned for the past 30+ years. Before this Sienna, I bought a 2003 Pontiac Montana that I put 253,000 miles on it with zero engine issues. The rest of the vehicle was falling apart after 11 years, but the engine was still going strong. I highly recommend AMSOIL products!

People think I’m wasting money buying Amsoil. That’s till I tell them put it in and instantly increase your mileage by two MPG! Just try it!

I use AMSOIL in all the fleet and personal vehicles I maintain. I recommend to everyone to switch to Ams. I recommend the signature series to those who do a lot of driving and want to maintain a long lasting engine.

Can't express how satisfied I am using Amsoil in our family's vehicle for the last 11 years, currently the Pilot has 311,000 thousand miles and going strong, by doing the recommended maintenance and using the best oil we expect to vehicle to reach half a million miles.

The best oil you can buy. Been using Amsoil engine oil for many years without any issues. Dealers that it ships from are always awesome and quick to ship. I love Amsoil.

I was skeptical that the oil would last a full year but it in fact did and was the one oil change annually I had to do.

Amsoil is a superior oil and I will continue to use it as I have for many years!

This oil have just what it take for those noisy Coyote engine. That typewriter tick that drive you up the wall and so I don’t have problem. Thank to Amsoil it been worry free for me and I love your products.

Love this oil . 6000 miles between oil changes , and great protection for my daily drivers

Would recommend,,, you want the best this is it... 👍

This oil is amazing it keeps the motor clean and cuts down on wear

This is the best oil on the market. I have changed my explorer and my eco boost truck. Completely different vehicles. Trust me the eco boosts go bad with bad oil and no problems with them.

I use Amsoil in all of my vehicles

As usual good service and delivery for a superior product.

This oil is second to none. Great protection and great performance.
