The oil and filter change to Amsoil reminded me of when I once had the power steering fluid changed, but this was my car's motor; wow.

I started using AMSOIL synthetic oil products some years back and have not had any engine issues at all since then. Test after test proves that their product is the best on the market and I am a firm believer that it is superior to all other brands.

Lots of people believe that most of the additives and selling points in motor oil is just snake oil. And I would say there is definitely some truth to that, I don't know what is real or not but I do know I can feel quite a significant difference when I switched to amsoil. My 370z runs super clean and very smooth. It was smooth before but I didn't realize how smooth it could be until I switched. Your car will thank you

Love the extended drain intervals. Only oil I trust to do it with

I have been using this product in my 2017 Subaru outback from the day we bought it. Oil is still honey gold when drained highly recommend this product.

I've used Amsoil in almost everything I own. Never had any issues and strongly suggest using it in everything from engine oil to chainsaw bars

Arrived quickly and as ordered. Only issue was free bonus was not included or sent, even though requested with the order. Maybe next time?

I’ve been buying Amsoil for decades. I’ve never been disappointed in the quality. I have a new F-150, I’ll be dumping the break-in oil at 500 miles and using signature series 5W30 (not 5W20). Anyway I strongly believe in Amsoil.

I have been using Amsoil oils for about ten years now. In my opinion this is the best oil for my vehicles. I trust all Amsoil products.

This is top quality oil Would like a change in sales When I just need 1 quart oil should be able to purchase oil in a store for right now usage

Great oil

I have just started using the amsoil 0-40 oil in my 2020Vette, and hope to achieve the results I've gotten in my 2009 Toyota Venza. The Venza has 227,000 miles and we use it as our main vehicle still. I have used amsoil in all my vehicles including my Harley's, Old Oliver Tractor, and assorted cars over the years. Never a complaint. With the additional mileage it afforded me, I believe I have saved hundreds of dollars... Bernard

La consommation d'huile est réduite de moitié... presque nulle!!!

I've been using Amsoil since 2005 and enjoy the added performance to the engines I use it in. Great Product!

I’ve been using AmsOil Signature Series Synthetic Oil in my Raptor and Bronco since they were bought new. Had an incident in Baja with my Raptor that really made me a true believer! A rock put a pin hole in my oil filter. I started smelling oil, but didn’t know if it was coming from my truck, as we were bunched together on a run. My gauges never read low oil, or the engine temp going up, both were steady, even though I lost over a quart! Changed the filter, topped off with more AmsOil, and was on my way. Truck never skipped a beat! Great job, AmsOil.

Can’t go wrong with amsoil products. I’ve switch all my cars to amsoil. Best in the business!!

Excellent products

Noticed difference in engine operating immediately.

Best oil ever made! I highly recommend using it!!
