Customer Ratings & Reviews

Hands down the best engine protection ever made available, I use nothing but amsoil in all of my vehicles. They run smoother with less noise, if you want true protection go with amsoil!!

I have been using this oil for year with my old 2007 ram and just started with my new 2022 ram. I believe it saves me money in the long run by helping to avoid major engine repairs.

I use this oil in my older Tacoma, its rated for 25,000 mile oil change intervals. I change mine every 15,000-18,000 or so. Great oil that comes out, never any sludge, I think the additives in this oil make it the best in the industry. On my next oil change, I will send a sample to Black Stone Labatory for analysis. I don't expect they will find anything out of the ordinary.

I only use AMSOIL for all of my farm equipment, my 2 trucks 2003 Ford Super Duty, 2021 Ford Ranger, and I have other vehicles that I also have. I have used AMSOIL IT SEEM LIKE FOREVER. You cannot go wrong using the best oil on the market. I know I am 78 and I still change my own oil.

I change my oil every 6,500 miles on my 2022 power wagon I do alot of highway miles so I need to put a oil I trust in my truck

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
