Customer Ratings & Reviews

Oil kit is real sweet with the gloves and funnel made it real easy to change the oil.

Yes, IMHO, Amsoil 5w-30 Full Synthetic is the best oil out there. Won’t run anything else. Might be a little on the expensive side, but so is a rebuilt engine😂. Seriously though, it’s great oil!

This oil is literally the best oil ever. My Toyota now has 430,815 miles on it and still going strong. I love amsoil will never in my life use any other brand I even run it in my lawn mower and dirt bikes. Keep up the great work and excellent top tier oil products. Thank you guys. I’ve been using amsoil for over 20 years now.

Best synthetic oil. Keeps motor running strong.

Highly recommend. Great product at a great price.

Love Amsoil and their products!

Just got a brand new engine replacement on a 3.3 v6 Hyundai Santa fee and ask them if I could bring or told them that I wanted Amsoil signature serie synthetic and they said they would put synthetic but only what is recommended wich was either Shell or quacker state so as soon I got out the dealer after 21 miles drop it and put this in I like to protect my investment thanks Amsoil

Have many years using this Oils and I wouldn’t trade it for another brand.

Didn’t believe in it until I tried it for myself and noticed the difference performance in my car 🙌🙌🙌💯💯💯💯

The best oil on the market I feel; tested and compared to other top names it always comes out on top !

We utilize this for a lot of Mazdas, each of them is doing outstanding with the oil. Good bump in mpg, and heat down. Much more pleased with smoothness under throttle, delivery of power is exciting. Going on 105k, 177k and more we love the performance and protection. All of them raced!

I have been using Amsoil Signature for almost 20 years on multiple vehicles. The results have been outstanding. The engines on my cars run flawlessly, especially in our very cold Alberta winters. I will never use any other oil.

Love the Products, Its like Franks Hot Suace. I put that **it in everything. Show cars, Race Car, Jeeps, If it takes Oil, its Amsoil. Bonus I have the best dealer, in the United States, who also supports Veterans. Hinson Synthetics.

Better oil by far than the Mobil 1, Castrol , etc.

Had my oil changed and the technicians told the guy at the front desk, This guy uses the good stuff.

Always Amsoil All the Dam Time!!

Have used email in Ram 1500 since purchased new in 2017. Have done the research on Amsoil and other synthetic products, have prices of mind that the Amsoil product is providing the best lubricators for my truck. Have also expanded to using in my jeep wranglers after I did rebuild on both of their engines. Will continue to use into the future.

After reviewing and reading information about AMSOIL, Changed out Mobile One to AMSOIL in my TOYOTA. I've been using AMSOIL in my commerical lawn mowers for a couple of years and pleased with quality of protection. Thanks

I am being very honest here! I have been using Mobil 1 0W-20 for 12 years with zero complaints. I have used Amsoil 20W-50 in my HD motorcycle for 10 years and never used anything else. I tried the Amsoil 5W-20 signature series in my 2010 Toyota Tundra 5.7 last Spring. Below 60° I started to hear a tap tap tap noise. I never had that happen before. So I drained the oil and changed the filter after 1,000 miles!!! I switched to the Amsoil 0W-20 signature series and the taping noise was gone and never returned no matter how cold the ambient temperature was. I pull a 6X10 enclosed trailer pretty much. I contacted Amsoil and mentioned it, and asked how many miles before an oil change? The reply was 15,000 miles max. I never planed on going over 10,000 miles before an oil change, or once a year whichever comes first. I am very pleased with the Amsoil 0W-20 signature series motor oil.
