Before I decided to purchase Amsoil, I did a lot of research on synthetic oil. I thought it was a scam and didn't trust the claims of long mileage between oil changes. I decided to take the plunge and buy Amsoil. I have been very happen with results. I was concerned about the higher cost per quart, but now I know it is "cheaper" (less expensive) in the long run. I have been changing my oil at 20-25k miles. Compared to changing my oil 3-5k miles was costing me three times more money!! Plus they ship orders very quickly usually get my orders about 3-4 days after I order online. Very happy!!!

Use it for many years and will do so further.

cant beat the quality ! only oil i use in my c7 vette!

2008 fj cruiser v6. 150,000 m. Had a little clicking sound. Changed to amsoil second startup noise was gone. Been using amsoil for a while now in our new car. Can't even hear it run. 2020 kia soul

I have been a preferred account holder for 15 years and use many different Amsoil products. This Signature Series has a lot of great properties, one of my favorites is the low pour point for long cold winters up here.

I been using amsoil scene 1974 and have lost a motor or gear box with amsoil in them right now I own a company that runs close to 300000 miles a year and all my fleet is on amsoil.

I have been using this product for 15+ years in multi-brand vehicles. I have never experienced a negative oil related issue. My engines remain unbelievably clean and oil consumption is minimal.

The vehicle has 200k so far, has had amsoil its entire life minus a few oil changes and I have no complaints

Changing all my vehicles over to Amsoil. Less expensive in the long run.

Have put this oil twice now in a 2011 Hyundai Elantra that had developed a lifter knock. Although the knock has yet to completely go away it is better than it was with more jump in the motor. Combined with a Wix or AMSOIL filter it is the perfect solution.

Using in a pair of Mitsubishi RVR's, a 2011 GT and 2012 SE that my daughter's have. Have had no complaints and the oil lasts longer than conventional and saves money with fewer oil changes.

Awesome product with amazing results and protection

After 60,000kms in my Subaru I switched to this engine oil. I instantly noticed smoother revs, more power and improved fuel economy. Definitely worth it!

This is what I put in my GT350 which are notorious for oil consumption. Since switching from motorcraft, it took two oil changes to get all the motorcraft as there are ten quarts, I notice little to no consumption and cleaner looking oil longer. Especially since turning the engine at 8250 rpm. Gives me much more peace of mind.

Changed the oil to this on my wife’s 2012 4 cylinder Corolla and it purs like a kitten and runs real smooth

I used to use mobil 1 only in my 4runner till i read up and watched scotty on my computer. If its as good as it sounds ill give it a try in both mine and my two daughters vehicles. At this price you should give a per case. G.L.G

Excellent service and pricing for a really rather excellent product. I’ve been using this on my 2017 GT350 for 6 months now and it has been brilliant so far.

Hello, I have been using Amsoil Signature series ow-20 for my 2017 Toyota Tundra. This oil performs better and last longer than anything else on the market. My truck runs better than new. Oil changes are a breeze and it provides a maximum amount of protection for the engine. I have total confidence whether I'm running at high speed down the interstate or idling in bumper to bumper traffic that the engine is totally protected all of the time. I am definitely a customer for life. I feel that Amsoil has put the time and dedication and research into making a superior product for consumers.

Great Oil and Filter. Would not use anything else. Worth the money

Run Amsoil in every vehicle, believe in the protection it gives
