Customer Ratings & Reviews

I'm not new to Amsoil however, my latest vehicle a 2018 Subaru forester would be considered the newest. I purchased the vehicle new and have always felt totally comfortable providing oil changes for this vehicle every 13 thousand miles driven or 12 months. At replacement the oil visually always looks fine. No buildup of deposits in the oil filter, no thickening of the oil, no foaming or sludge. The Signature Series oil provides 75% more wear protection to assist the high mileage change of the vehicles oil along with the EA15K13 oil filter. I wouldn't push my oil changes to 13 thousand mile's without the use of the EA15K13 oil filter. Without the filter I would most likely replace my oil for this vehicle between 5 - 6 thousand miles.

How to use Amsoil products for years they are absolutely the best. My 2012 Kia Soul explanation has 390,000 plus miles & there is virtually no wear to the engine. I've used other oil brands and they are virtually no contest to Amsoil oil... all there products are amazing

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
