Customer Ratings & Reviews

I just had a 600 horse 460 Ford built and put in my truck and this oil is the best insurance for a hydraulic roller cam motor in my honest opinion..

This product goes in all my vehicles!

Best oil on the market!

Well, I am not the guy who owns a mega-truck or 5 SUV's. I have the "love of my life" who's stuck with me for 38 years and a major cardiac failure. My goal is to make sure that this investment of my life sticks around for awhile. Everyday she gets in her 2013 Honda CR-V and takes to the roads. Her rig WILL have the BEST I can afford protecting her. This is why when it comes to the products you make, they will be used. When the BEST is used there is no need for excuses!

I have been around cars and trucks since I was 11 years old...rebuilding, normal maintenance, restoring, and mechanical. At almost 70 I can tell you that my pride and joy is a 1998 Chrysler Town & Country LXI mini van. I proudly have 385K Amsoil miles and it still runs like new. I get exceptional mileage, no smoke from exhaust, no rough idling, no engine noise (that most older motors get), and can say after sitting in the drivers seat all those miles...I still love to drive it and see what new gets better! I am constantly surprised at how smooth a quiet the motor runs. When I take it get my tires rotated they always comment on how well it runs...here is the irony. When trying to explain about additives there is a blank look as people just don't understand that synthetic oil is engineered not manufactured. A lot of time, research dollars, and effort has gone into the making of each product. I will always explain the benefits of Amsoil when asked...just get tired of people that are ignorant to the science and technology that has made this product what it is. I have been a 20+ year user and will always continue! Thanks Amsoil for sticking to your desire to be the best!

Used it in my 2015 Ford Fiesta rally car. Seems to be working. will buy again in couple months when time comes to change oil and filter!

This is the best oil I have ever used

I've been using Amsoil products for many years. I don't have to worry if I've gone over the 5,000 mile interval, because I know Amsoil will protect my engines. The oil filters are top grade, and great to use with Amsoil. I also use many other AMSOIL products. The gun cleaner and gun oil is excellent for my police service revolver and I use it faithfully, knowing it will protect my pistol, shotgun and assault weapon. The cost may be slightly higher, but the protection is excellent and guaranteed to perform.

Senior master technician in ford dealership. Have seen how these long life synthetics work when pushed to their limit. 7500-10000 mike oil changes don't work with other products in my opinion. Have seen the difference on internals in tear downs. Won't use anything else in my vehicles from my focus to my super duty.

It's simply great oil made for great engines. If you have a boosted engine stick with the best, you won't regret it.

Been using this in my DD/cars for the past 10+ years and never any oil issues. Good stuff.

I use it in my 2014 Chevy Silverado

In my truck

Oil exceed all expectations.

Have used for years on my 2000 Chevy Impala, 1995 Toyota corolla, 2010 and 20 12 Toyota Prius, and will be on my 20 17 Rav4 b

Since day 1 of the first oil change, and several others, 45K miles later it's still running like a champ. I've been using Amsoil for years. Nothing will change my mind.

I use Amsoil Signature Series 5W-30 sinthetic oil in my 2006 Solstice and my 2013 F-150. Amsoil is the Best and wouldn't use anything else.

I have 0 complaints about any product that I've used yet. My 06 Silverado and 07 Trailblazer both get Amsoil. 15k Mike changes with 0 issue

I started switching my 10 vehicles and dozen or so pieces of yard and garden equipment to Amsoil several years ago. I had been using Mobile 1 for a long time and heard some things about it I didn't like so that made me decide to switch. I moved into the Amsoil product line very slowly always wondering if it would be a mistake. I do oil analysis on every oil I drain out and a virgin oil analysis on every new product line I start using. After several years of making Amsoil prove to me it was better than what I had been using, so far they have in every case been able to do that. In my engines I'm running Signature Series and have increased my OCI buy 3 times what I used to use and oil tests are showing better performance than what I saw with a third the distance using Mobile 1 Extended Performance Oil. In transmissions they are shifting better and once again the analysis shows better results. Likewise with Differentials. I now just across the board trust any of my vehicles or machines to Amsoil products.

This is a great product and I use it in all of my vehicles. The biggest difference is that all my motors run quieter than any other product I have tried including royal purper. Could not be happier.
