Customer Ratings & Reviews

I've always used Mobil 1 and have nothing bad to say about them. I purchased a Jeep and have a job that requires me to drive 180 miles round trip. I've heard about AMSOIL for years and never tried it. Now was the time. I ALWAYS buy the best for my vehicles since it's what gets me to and from work to earn what pays my bills. Here we are and I cannot say anything bad about AMSOIL. Yes, it's more expensive and I cannot say whether it's better than MOBIL 1, but I have the piece of mind that I have the protection I need for repeat, long distance driving. AMSOIL's data says a lot and in detail. Another selling point for me. Buy it not. Take my word or not. Whatever you're putting lubricating products into, you spent hard-earned money on to buy. Why not put the best money can buy into it? No-brainer to me.

I USE AMSOIL IN ALL MY MOTORS!!!

I have never had a problem in 20 years getting the product shipped to me in time to change the oil in my vehicles and it consistently over performs. Thank you!

Used on a friend's 2018 Impreza WRX and the wife's 16 CX-9 both of which had notable smoothness improvements and better spool response. Oil has worked as a detergent as well, since use the car has needed less encouraging to accelerate or run in winter.

I use this oil in our Honda and Toyota. It holds up very well with high mileage. I don’t use anything else.

Always use Amsoil motor oils, transmission products, filters and fuel products. Current vehicle at 292k miles, previous vehicle sold at 297k and I understand that it went past 350k. I intend to use their products until I hit 2 million miles myself.

I actually was told about Amsoil by a friend, one of those nut cases that does too much research into everything. I have an older truck, that I want to take care of so I try to feed it the best stuff I can. Amazon works great, their website is easy, their shipping is fast, their customer service is top-notch.

This oil stays cleaner longer and the oil itself doesn't break down. I run the Signature series 0 w 20 oil and the EA Filter. I drain and fill every 15K miles

This oil does what it says highly recommend this oil to anyone

Always quick, packaged professionally, and pricing is reasonable.

Everything was included and easy to install and use! Greatest Oil, easy filter install with all accessories included.

I use your signature oil in every vehicle we own and have done for 15 years. They are the best product out there.

is the best product

Amsoil is and Always been the most outstanding oil on the market. I’ve been using it for years and would recommend it to anyone that is thinking about buying it. Get it and treat your auto to the Great oil.

Great product, not happy with shipping cost. For what the cost is for the product and membership fee, shipping should be included

If the amount of videos they have showing the difference between them and the competitors isn't enough then the reliability and customer service will. It's a noticeable difference after switching to amsoil, the motor just sounds healthier and cold starts at 20 degrees both in my bb gas and diesel are almost instant oil pressure reading and you can tell the oil is going where it needs to. Even during the summer running high Temps and towing the the oil stays viscos and doesn't just thin out to crap. I'm sold till proven otherwise.

I drive a 2007 Toyota Tundra 4.7L V-8 2 wheel drive. These vehicles are known for dependability and running forever. With my truck at 260,000 miles (it runs like a new one) Amsoil is my first choice for engine.

An excellent oil at 0W for low temperature flow and start up when the weather is very cold.

Been using this stuff since 2018. I used Blackstone labs to confirm performance. I can say 25k, or 1 year is for real. I use it on all my vehicles.

This is a great product for the price.
