Customer Ratings & Reviews

I drive 30k miles a year and like the convenience of trusting Amsoil to 25k oil changes. Keeps internal engine clean and clear of varnish deposits like I had with other oils.

Love the amsoil products, always fast delivery too

After I start use this oil my MPG went up a bit, smoothen engine work and quiet.

My Chrysler van may not turn on the change oil soon message for 10,000 miles. I have no worries as I know the Amsoil Signature Series has my back and will protect my 3.6L engine for that mileage and more. I have never had an engine mechanical failure and I owe it all to superior Amsoil protection. Amsoil is fantastic insurance against engine breakdown and worth the price. Thanks for a great product.

Eat oil on the planet. Our van runs better and quieter. Amsoil only for me!

My Evo X, Jeep TJ and my girlfriend’s Corolla all get Amsoil. From the research I’ve done personally on engine oil amsoil is by far the best out there.

Spend now, save later. Saving money on lower quality oil costs more in the long run. Almost 300K on my 01 Tahoe and still running strong.

GOOD stuff

I’ve used AMSOIL products since 2008 and have never been disappointed with their performance as prescribed…..IT WORKS!

I use Amsoil 5/w 30 signature series in my f150 for 7 years now, runs great at 60,000,where I worked before retiring they used Amsoil in a fleet of buses for many years with no oil problems I would recommend all there products,not just there oil.

Best oil u can buy. Nothing else to say.

Only oil that has been used in my 2012 truck and 2017 expedition.

Best protection for your vehicles

I've been using Amsoil 5w30 with the EAO oil filters in my automobiles since 2005. The savings in oil changes only makes good sense plus less waste oil. I only change my oil once per year. I drive approximately 12000 miles per year. Can't beat the preferred customer program for additional savings.

Best oil on the market in my opinion. My scat pack loves it.

Need some time to pass before evaluation to be accurate. The oil has been in my vehicle for a short period of time. Everything seems to be working well up to this point. I feel this is going to be a lasting relationship with Amsoil

Awesome product

Thisnis the second oil change with this product. My truck is getting older and nearing 300kms I thought I wanted a viscosity change. The 5W50 gives me all of the protection I need while not being thick and gooey. I love it and my truck loves it.

This product is also used in my truck as for back as 1984. Super product for long mileage and superb mileage. Thanks for a great product.
