Customer Ratings & Reviews

I have only used the Signature series in my 2016 Chevy Colorado, just rolled 235,000 miles and still goin strong. I do a 25,000 mile interval due to the miles I drive a year. I have had zero issues with my truck and still drives strong and gets good gas mileage.

My uncle who owned a shop when he was alive ran nothing but amsoil. Didn’t know why but he loved the product. Many many years later I see why ! I’ve used Mobil 1 in all my cars for years thinking it was the best until I watched a YouTube channel Called project farm. Amsoil out performed all the rest and now have been using amsoil for awhile now. Won’t change back. Other oils like Mobil 1 may be cheaper but that’s what u get !

Great oil. I would not use any other. I have seen the YouTube video evaluating different oil and Amsoil comes out on top.

For my last three orders I have selected and used the codes for offers like free lubricant spray, shop towels, magnetic bowls etc. each time they do not ship. I have attempted to contact with no response. My son looks forward to the stickers and this time no magnetic bowl, no stickers. Its not a huge issue but you asked for feedback and here it is……

As advertised great product

The hype is real. You immediately notice your engine is running smoother when you switch to this. Had a valve cover off and it looked brand new underneath. Not 1 stain just brand new looking metal. Have gotten close to 25,000 miles before but changed due to towing and hard driving.

I have used AMSOIL products in all my equipment for about 40 yr.

Been using this product for over 20 years in all my Vehicles,ATV's and Lawn Equipment. Amazing Product with a company that actually backs up all there claims and provides all the product testing results. Also Customer service #1 with real people.

The only oil i will use.

After reading the article on full synthetic oil versus 100% synthetic oil I think the term full synthetic is a lie. I’ve shared the story with others and they cannot believe our legal system allows such a ruling. I guess money talks. But I am changing over to 100% synthetic for all my vehicles. I believe AMSOIL is the best oil on the market.

Best product / oil you can buy period. Use it in all my vehicles especially my C6 Vette. External independent testing also indicates it's simply the best out there.

I have a 1997 Mazda Miata race car with 120,000 miles on it. The only thing I would consider putting in the engine is AMSOIL 10w-30 Signature Series. It gives maximum performance every time on the track.

I have used Amsoil since back in early 90’s. I see Amsoil that produces long lasting oil than any other oil I know of. I just drained used Amsoil oil, it darkened but the lubication is still there. My Ford Explorer towed Airstream Flying Cloud 19’ from California to West Virginia without any engine issues.

Very impressive with the oil. I notice the vehicle is running smoother and quieter. This product is very new to me. I will continue to monitor the performance.

Use this specially in the wifes wrx, 5k ool changes. The blackstone labs oil test I've done so far have come back great, only thing that they note is the oil is slightly below it's weight

Did not include the free Amsoil magnetic parts tray that was supposed to be included with all orders over $100 (which mine was). This is the second time they have failed to include a Amsoil premium with my order. ( A hat, I think.) Just no free advertising for Amsoil. Otherwise great products.

great, change yearly

Best motor oil ever made. Worth every penny.

For anybody that wants Longevity on their motor this is the way to go . Can’t said anything else to describe how satisfied I am with the product

Use all their products in my jeep. They hold up well and preform great under harsh environments.
