Customer Ratings & Reviews

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.

I highly recommend this oil. I always uses Amoil motor oil. I noticed how smooth the engine feels every time I uses Amsoil. When I change to a different brand of oil the engine doesn’t feel quite as smooth as using Amsoil. Amsoil starts up better during the very cold months here and it’s stays clean longer than other oil that I noticed.

I’ve been using Amsoil for 26 years. This is my second 3.5 eco boost Ford PU. I tow either an 18’ enclosed trailer with up to 5 motorcycles a 22’ IO deck boat. Oil pressure stays the same regardless of ambient temperature or load. Oil temperature and engine temperature are the same bob tail or towing. I change the oil every 5K miles. No turbo issues or cam phaser issues with my 2014 or 2020. I also use Amsoil in my boat and motorcycles. No consumption or indications of issues. Yes, it costs a bit more but peace of mind is worth it.

Am very pleased with this product

Don't you just hate it when a product speaks for it's self. The wife and I, and our 2015 Ford Flex (3.5 fuel injected w/towing package) and off we go again to southern Florida, bass fishing, towing a 16 1/2 ft. bass boat full of fishing gear. Before we go, I change the oil and filter ( Amsoil XL 5W-20). 1 month and 7,475 miles later, always pulling the boat and trailer, we arrive back home. The check oil light has not come on (which senses the oil's integrity also) and there is no oil lose on the dip stick and the engine ran normal temps. the whole trip. Come on Amsoil users, what else could you possibly ask for from your engine oil.

Great service an shipping eng never uses any oil with amsoil products

Toyota highlander 3.5v6 engine less chain noise. Idle speed higher, mileage a little better. Like the product and would recomend.

Excellent product as always. Superior performance. I have been using this oil in my vehicles for the last 8 years and I love it!

I've used amsoil in all my engines since 1992. My 92 GMC has 280,000 miles on it and still runs great, does not burn any oil. Couldn't ask for a better product.

I use AMSOIL in all my engines transmissions and final drives. AMSOIL reduces friction there by increasing fuel efficiency. I've tracked the milage on my two main daily drivers and both had milage increases of two to five miles per gallon. Every vehicle is different and every driver is different so results may very. But that being said, I'm very impressed.
