Customer Ratings & Reviews

Best oil I have ever used. Makes a very noticeable difference when paired with regular oil changes

2018-2020 F150 5.0’s are notoriously loud engines, mainly from the direct injection pump/injectors. This oil made it much quieter. Runs so smooth. Delivery was fast, and package was is great condition and well packed. Thanks AMSOIL! New life long customer.

I started using amsoil about a year ago and I’m never going back to using anything else. I put it in my 2013 f150 with 180000 miles on it and took a 3600 mile trip cross country with my motorcycle in tow my truck ran quite and smoother than ever and I got 4 1/2 more miles per gallon then I did before using amsoil. And now I use it in my bike too thanks amsoil great product

Not only am I getting the best motor oil on the market for my Lexus but, it is literally here in a day after the order is placed!!

My car is left unattended for months at a time going back and forth from Pa to Fl. Knowing it’s 25 k mile oil gives me piece of mind, needed to change annually. You just can’t beat Amsoil products

The products that I purchased were absolutely excellent. Ever since I changed out the transmission fluid, engine oil and gear lube to amsoil my truck has experienced a much better performance, fuel economy and less stress compared to other brands that have been in my truck 100 percent worth the expense you pay for what you get with amsoil

Best darn oil you can buy. Great it will last up to 25,000 miles.

The best decision I’ve ever done will definitely keep buying for this car.

Should’ve done it sooner OMG WHAT a difference….!!!

I have been using Mobil 1 synthetic oil since 1985 thinking it was the best money could buy. What a huge mistake. I'm sold on Amsoil motor oil and gear lube.

Have used AMSOIL oil on 2003SVTFocus and 2011Saab 9 3. Both cars have done well on this oil.

Great oil with rich history in motorsports. Have always used full synthetic mobil products and recent research had me try Amsoil. Decided to stick with it for all of my cars and friends cars I do oil changes on.

Have been using this oil for 20 years I like only changing oil once a year and have had no issues I keep my cars to around 200k miles then sell them only because the body is rusting out motors are still purring like a kitten

Looks like a great hole a lot of good reviews. I'm switching from mobil1 too amsoil

Mon f-150 2014 avait un petit claquement à froid et depuis je lui met de la amsoil il ronne comme un charme! Et moin besoin de faire des changements dhuile souvent ce qui économise du temp et de l’argent!

I have always had great response to my ordering and the product without question the best you can buy.

I use an Amsoil engine flush and I put the signature for first and after 2000 miles I notice that the engine was extremely quite, amazing. With 180k miles it is running like new.

The shipping is fast and easy. No an engineer on oil, but I trust the great reviews. Hopefully it protects as advertised

Been keeping my high horsepower beast efficiently running safe for years. The best.

This has been in my fresh engine since the break-in oil was changed. Love it and I feel it has been the best oil I have used in any engine I have built!
