I thought Amsoil was only available thru special dealers but my neighbor told me otherwise. Been using Mobile 1 for years but finally made the switch. Delivery was fast and complete. I know I'm putting the best oil in my GMC and that's all that matters to me.

This is my go-to oil for OE replacement for my newer vehicles.

Definitely a piece of mind in performance! Everytime I change my oil I can confirm the quality & believe me I run my ride to the max!

Love the product but this is the first time I have had to wait over a week for delivery!

Excellent product

It's been two years since I made the switch to Amsoil for all of my vehicles. I run the OE 5w30 in all of my vehicles, it has been outstanding since day one! Out of the six vehicles it's in, three are turbocharged, and two are V8s. The OE 5w30 has proven itself to be perfect for all of my vehicles.

We use Amsoil in our helicopters…I feel confident using it in my F150

we have been using Amsoil products since 2000 in all our cars and trucks and motorcycles it is simply the best oil money can buy.

Seems to be good. Haven't had long time use yet. Very fast shipping.

This is a quality product that meets OE specifications and is still affordable it's held up to my high standards

I use this in my ZL1 love it. I used to go to the dealer pay out the nose. Now do it myself and save over 150.00

This is an excellent choice for the everyday driver on a budget! The price is right in line with other top synthetics and even cheaper if purchased as a preferred customer! Amsoil has been my go to oil for a very long time!

I only use Amsoil in my Truck, Car, and Harley Davidson. Amsoil is the best on the market I truly notice a performance upgrade since I have used this product. U won't be disappointed, I recomemd nothing but Amsoil....

Excellent product for an even better Price. Was very surprised with how quickly it arrived also. Def will order more products from AMSOIL

Amsoil is all I use now. It is the best performing oil I have ever used in my fleet of work vehicles as well as my boat and son's dirt bike. When I change to Amsoil the engine sounds drastically quieter. Customer for life. Jeff Fletcher

Hasn’t burned any of it using it. I was with using acdelco

I used the 5w20 advanced engine protection oil for the first time in my new F-150 2.7 twin turbo. After changing the oil and filter the start up noise was less and over all engine noises are much quieter , plus my fuel mileage has increased by 10% ! Thank you Amsoil

The first oil change for my 1997 F150 after purchase used AMSOIL and every oil and filter change thereafter. Recently had to replace head gaskets, the mechanic surprised when he noticed the original hone marks on the cylinder walls and how much power the engine still had.

Using in our 2014 Chevy Malibu. Works great.
