Customer Ratings & Reviews

I have a 2005 Dodge magnum with the 5.7L Hemi that I bought with 2200 miles on it. Shortly after I switched to Amsoil and it now has 130000 on it with only 6 oil changes. All Amsoil oil and filters. At 100000 the transmission and differential were also changed to Amsoil. I have had no problems.

Don't worry

Love this stuff have been using it for years!!!

I use it in both my trucks, and I'll keep using it. Great oil, great filters, I've never had a problem with the oil or filters.

8k Miles between oil changes.

I commute 6 days a week from Sacramento to San Francisco this product last longer than any other product I've tried that supposed to be comprable gas mileage is improved and overall performance is noticeable

I have been using AMSOIL products in my vehicles since the late 2000's and I've been more than satisfied with these products. Most recently, I've been using the Signature Series 5W-20 Synthetic in my 2008 Honda Accord and it does not disappoint. Why do I say that? Well, turns out my car has a mysterious oil leak and once I realized that my engine has been out of oil for an undetermined amount of time, I started to panic a bit, but then realized just how well my engine was still running. Hard to believe, right? Exactly. I was astonished that I had been driving without oil and didn't even know it. The oil indicator on the dashboard didn't even come on. I checked the dipstick and it was bone dry. I wondered how come my engine hasn't blown up yet considering I had been driving for some time without oil. All, I can say is, I don't believe I can do that with any other oil product. Even my mechanic was shocked that my engine was still running as well as it had been before he checked the oil and told me it needed to be repaired. If you haven't tried any of the AMSOIL Motor Oils, I recommend you do so. I'm no mechanic, but I believe my car wouldn't still be running or performing normal and well (even on the freeways at freeway speeds) if it hadn't been for the AMSOIL motor oil that I use. I recommend their products to everyone because I believe the products perform as well, if not better, than described.

I'm city driving in a 4x4 Ford van and after my last oil change the oil was still in great condition after 15,000 miles. just used the cleaning solution so lets see how this improves engine longevity. really happy with all th products I have received.

I use it in my Subie Forester and my silverado 1500. no problems ever!

I use Amsoil Signature Series in both of my cars that are susceptible to burning oil. The 10W30 goes into my Honda S2000 and works great! Amsoil is the only oil I use in my motors and gearboxes, after trying out several different brands, I have found their quality to be of the best.

I get better mileage with Amsoil I run my 4x4 very hard and Amsoil is doing a great job of keeping it running strong

My 2004 Silverado (5.3L V8) has had a steady diet of Amsoil since its second oil change. I have stuck to the 10,000 mile interval, using Amsoil Ea filters & Signature Oil. She's about to roll over the 200,000 mile mark, and I have had no engine issues. I use Amsoil Signature Synthetic Oil in all of my vehicles, and plan on keeping it that way.

Yeah like to 25,000 my old changed

I will never use conventional again. 10K mile Oil changes, or once a year. You cant beat the quality and value of this product. No dealer or mechanic can ever persuade my to change every 3k miles again!. Get you some!

I personally believe that with the history of Amsoil and their pioneering spirit I am getting the absolute best product on the market. They have been doing this longer and better than anyone else for a long time. Can't beat the best!

Bought Amsoil for all of my cars so I wouldn't have to change the oil so frequently and for the protection it gives all of the internal moving parts. I've noticed an increase in MPG and smoothness when I drive. 2017 Civic Type R 2012 Pilot Touring AWD 1998 Civic EX

I use this in my 2005 Jimmy 4.3 Vortec. I've started using it since 30,000 km on the vehicle which I've owned since new. I love this oil. I go one full year 25,000 km before I change the oil along with the Amsoil filter. Oil is great, engine runs quiet and effectively with this brand.

Started using in my 08 Subaru saw better gas milage the car ran smoother so I began to change ever gas engines l own to amsoil. Couldn't ask for a better product !!!

I've used amsoll since probably 1990 in my mowers my pickups my tractors. I swear by the signature series it's done wonders for me and Increased gas mileage you have to try it for yourself to see the picture

Hold up to heat and high horsepower well withought having a high viscosity in cold weather!
