I use Amsoil on my SUV and love it!

Always met my expectations.

I have used Amsoil products for many years in all of my vehicles and small engines. I have never had an issues. I recommend Amsoil even though it is not the cheapest but the delivery is very prompt.

Using Amsoil in all of my family's cars. Using Signature series in cars that drive over 12,000 miles per year, and XL series in cars that drive less than 12,000 miles. Sent a 27,000 mile sample for testing to a independent lab, and they recommended 30,000 miles next time based on the excellent results. Also using Amsoil in all lawn equipment and for a standby generator.

Bestboil products on the market by far. I run it in all my vehicles

Great product gives better fuel mileage and cleaner oil after changes

I've been using Amsoil since the 1980s in everything with an engine. And have bragged about it's benefits to anyone who'd listen.

I have been using Amsoil since 1979. I started as a dealer while in the Air Traffic Control Acadamy. I maintain between 4 and 8 vehicles routinely [currently 7] and I would not have time for the routine maintenance if it was not for Amsoil. Amsoil is the best oil and by, far the best, oil filter in the industy. My twin sons just became 16 years old. For their birthday I taught them how to change oil in their vehicles using Amsoil. I am passing down the tradition of using Amsoil as my legacy to them. It is the best advice that I can give them.

This is great oil. My 1997 suburban has 298,000 miles on it all were with amsoil . No engine problems. Clean internals (had to remove the intake for injectors). No engine noises, used very little oil. I will be using the 0W-20 on my new one.

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
