Customer Ratings & Reviews

Great product. I have been using it in my Ram for several years.

Excellent quality product, I use it in both of cars happy with the oil change every 12,000 mile .I highly recommended Amsoil oil!!

Been using XL synthetic in my vehicle since I bought it, my engine runs exactly like it has since I bought it. Amsoil synthetic is in my engine, differentials, & transfer case & I will continue to use them

I use amsoil in everything. I just pulled valve covers off of my 2010 suburban and it was like new clean underneath. I wish I could upload pictures of the cover and valve train. I would not use anything else for lubricant unlessni just dont care about it.

Great oil my bronco runs so much smoother

This is absolutely the best oil for my engine. Nothing compares to AmsOil. They are the O.G. of synthetic oil and in my opinion are hands down The Best oil on Earth. I've tried numerous engine oils and this is the only oil I will ever use. Nothing beats AmsOil.

i have used AMSOIL for every thing from Stock Car's, Motorcycles, Lawn mowers, weed eaters, Snow blower, with no problem 1985 to present

154,000 miles and doing great

Used to use "majesty" purple. Would last about 1-200 miles before flipping out the pan black and thick. This stuff flows out with none of the apparent pressure buildup, a bit dark. This is after 2-2500 miles. I drive rather vigorously and an running a turbo'd 2.3L 4 cyl.

I am not a chemist so I really don't know how I can write a review for oil... it's slippery, looks clean. I guess I'll know if this oil is any good about the same time I get rid of the vehicle. If the engine fails before I want to get rid of the vehicle then maybe the oil is no good, but how do I know? Kinda stupid to ask customers to write a review for oil... it's oil is about all I can say...

Great products like always. Have a two decade old Toyota in Wisconsin with virtually no rust and keeping it alive.

The GOAT of all oils

NA

I’ve used Amsoil in mine, my wife’s, daughter’s and son’s ices (14 total), for more than 20 years. That’s how much I believe in Amsoil products.

Have trusted Amsoil for nearly two decades and have never been disappointed. The product performance and consistent quality speak for itself. The customer support is outstanding as they recognize the importance of remedying issues to the customer satisfaction in a timely and professional fashion.

Great oil that seems to keep engine cleaner longer, otherwise works well.

I've been using Amsoil XL for over 10 yrs now. I took oil samples from Mobil 1 before switching, and oil samples after. Amazing how little wear. Just sold my 2011 Tahoe with 185,000 mi. Compression test was excellent.

Quality oil always above and beyond expectations

I was asked to write a review on this product. This is the first oil change on my recently purchased 2019 MazdaI CX9! I have been using Amsoil products for years, their products are the best. I am sure I will be 100% satisfied.

I purchased this product for a supercharged Toyota Tacoma. I've used Amsoil products in the past for another supercharged Acura I had. I replaced all OEM fluids with Amsoil and their products performed to perfection. If you are thinking about it, don't. You won't find a better oil.
