I have used this oil continuously since 1996 in all of my vehicles. I lived in Alaska but moved to Delaware in 2018. Shipping has always been timely and reasonable. I tend to change the oil every 6,000 miles in the car, and once per year in the truck. (2011 Dodge.) The latest test showed no loss of compression. I could not be more pleased.
Been using Amsoil for over 30 years. Been using this particular oil in a 2005 vehicle since new on a 10k mile change schedule. It now has 240k miles, uses absolutely no oil between changes, sounds and runs like new and has never had an internal engine issue. What else can I say!
Bottom Line
Yes, I would recommend this to a friend.

This product is great! Increased my gas mileage smoothed out my idle and is just an over all great product I will use nothing else from now on
I'm new to amsoil but after changing all my fluids to amsoil i believe the car seems to run much smoother, and amsoil is very organized and easy to order from, fast shipping
I bought this oil cause reviews said it was good for direct injected boosted engines. Ecoboost engines have issues with high mileage carbon build up so decided to give this a try to help combat it. Engine is noticeable more smooth and quiet so I ordered more for my coyote mustang.
Bottom Line
Yes, I would recommend this to a friend.

Oil for 5.7 liter Tundra

Nothing is better than Amsoil oils for protecting your hard working pickup trucks!
I was always a mobile One fan but after doing research on Amsoil and buying a new muscle car I knew there was a better racing oil out there to use and I couldn’t be happier using Amsoil with all the benefits of lubrication that their oil provides !!!!!!!!
I've been using Amsoil XL for years now, we recently bought a van for our family and I wanted to see how XL held up in the vehicle after around 10,000kms.
So I sent a sample to Blackstone to get analyzed, they determined that there was still more than enough lubricants and additives to prevent wear, and that the oil was holding up very well at that mileage.
Keep in mind, this is XL, not Signature - so I assume Signature would be even better.
That to say, I'm very happy with the product and it's great to know that it'll easily last 10,000kms between changes.
Would definitely recommend :)
