Use this oil and there filters when in stock love the product recomend to everyone

I never go as long as the manufacturer says is allowed between oil changes. My current car manual states 10,000 miles or one year. After 2000 mi. I changed to Amsoil Signature. One of the few 0W-30 out there. I then drove to 5000 and the annual oil change was due. The warranty with the car required one free oil change. The dealer put in the manufacturers oil. In the next 5000 miles I had to add oil. In the next change I switched back to Amsoil Signature. In about 6000 miles is used less than 1/2 quart of oil. I think the difference is in the quality of the oil. The manufacturer uses some European stuff. It meets the manufacturers requirements but I don't think it is nearly as good as Amsoil

As far as I can determine, AMSOIL is THE ONLY true synthetic motor oil on the market. I am a 30+ year member of the SAE .

I have been using this oil for 3 years and it has been the best, longest lasting oil I have ever used. 40k Miles later my truck runs smoother than it did back before using it. Way to go Amsoil!

great item, does an amazing job, definitely highly recommended

In my opinion this is the highest quality oil you can run in any vehicle or machine. While it is a little more expensive than some others, it is engineered for enhanced wear protection over a greater time frame. Also it was delivered within 3 days which is always nice.

Been using amsoil in my truck and motorcycle for years and will never turn back. Highly recommend this product

I've always used synthetic but wow, I noticed a difference as soon as I was done with the oil change.

None better, always the top protection for your engine.

I only run Amsoil products mostly. After the change from OEM Dextrose to Amsoil 5w-30. I noticed again that things are a little more quiet. Valves and little ticking sounds in the motors always seem to go away.

For the road or the track nothing makes my GT350 purr like the beast it is!

these products are second to none.

I use amsoil in all my trucks. I've never had issues with it and it's still in pretty good shape after each oil change. It's worth the money if you like your car. Some people are fine with whatever they get at jiffy lube, but I am a little more picky with my oil. And this stuff has been proven good and it's got the reputation to match.

Offers great protection on my tuned Focus RS. I beat on this car everyday and have never had a single issue. Runs like a top day in and day out

Signature Series got me to 282,000 miles on my 2015 Chevy Cruze in 3 years driving Uber. I probably would have gotten a 100,000 more miles but I only started using Signature Series at 110,00 mile mark. It's the best. Anyone that really knows motor oil already knows this. My next new car will have all the fluids replaced with Amsoil products before the first 10,000 miles.

Good insurance great oil

Excellent product, nothing as better quality as Amsoil. Using Amsoil to all my vehicles. Nothing and is amazing!

Great product and great price need more for all my vehicles

It's engine oil. There's not much more I can say about it. It's one of the best out there. I noticed more of a performance difference from this oil than when I used Royal purple hmx so it's a thumbs up from me

Got 20mpg on my 98 3/4 ton 4x4 chevy pickup with this on the highway.
