Customer Ratings & Reviews

The best oil to get hands down. My truck has never ran as great as it does now ever since I switched to AMSOIL.

I love this product but my oil filter has been out of stock for months really frustrating

My first purchase from AMSOIL was a case of Signature 5-30W motor oil. It arrived in 3 days; excellent! Put it in my 1999 Lexus ES300 and it seems to like it. I expect no problems with this product.

I’ve been using this oil ever since I changed the oil in my new truck the very first time and my wife’s car from when we bought her car with 30k on it… I am the kind of person that keeps a vehicle for double the average time and Amsoil is my insurance policy to make that happen…

This is the only oil I will use in my car

Its hard to beat this engine oil thier is several oit there that are good but Amsoil definitely surpasses them as far as enternal wear protection cold starts high heat just cant beat it very high quality and highly recommended i use this in all my vehicles rite down to my military truck Deuce and half

I’m extremely happy that I can receive AMSOIL products where I am in Italy and that it can be shipped to my APO address.

I have been using the Amsoil Signature 0W-20 in my wife's Subaru Forester for close to ten years. It was the first year for the FB engine that was notorious for burning oil. To this day this engine has never had an issue. I also had an analysis done on the used oil and it showed that the engine is in very good condition internally.

Use Amsoil in all my internal combustion engines. Follow Amsoil recommendations….25,000 interval and filters at 15,000. Honda Civic had 185,000 miles on it when I sold it, used 1/2 quart every 15,000 miles. My Outback has 138,000 miles and uses a little over !/2 qt. I would say not much wear.

Perfect oil

I've used Amsoil exclusively on my vehicles and motorcycles. My Jeep Wrangler has 67K miles and the oil has been changed once yearly since new. Except for a couple of recalls, your engine oil has worked flawlessly for 9 years.

great protection. no problems from wear since I've been using Amsoil.

All the amsoils products are the best.

I switched to amsoil and haven’t regretted anything. All my personal vehicles have all fluids changed over.

Seems good so far and maybe even runs a little better. Haven’t driven that far yet after oil change. Less than 1000 miles. Truck has 285k on it.

Engine was cleaner and 100% more quite. Unbelievable what good oil can do! I hope to continue being a customer as long as I can afford it.

Great Oli

I've used this Synthetic Motor Oil 0W-40 since I purchased my 2016 Ram Power Wagon. After 157,000 miles and several oil changes, I can tell that I am getting the best protection for my truck in the main lubricant that my truck uses. During oil changes, I monitor the outgoing fluid and sometimes take apart the oil filter just to check for normal wear and tear. I have never been disappointed with what I have found and will continue to use Amsoil products.

Never disappointed by Amsoil products

Only product and viscosity i use
