Customer Ratings & Reviews

Every time I order, it is delivered very quickly & exactly what I ordered.....

this is the only oil my new EDGE will ever see, best oil on the market

2 Gallons are the perfect size for my F53 Ford Motorhome chassis (6.8 litres V-10). Makes that Winnebago purr like a Kitten.

Too early to tell get back with me in a year for grades.

Wouldn't use anything else. 1976 to today.

Have used several of the Amsoil products and love them all. Shipping is quite fast. Will continue to be a loyal user.

I love this oil and I feel it's the best you can buy for your vehicle. The only thing I'd love to see changed is the design of the gallon jug. It's hard to pour without making a mess. Need a no glug container.

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
