Given the properties of full synthetic lubricants compared to standard petroleum products, I would never consider going back to that old standard and with Amsoil's solid reputation for high quality products, they will continue to be my first choice in synthetic lubricants.
Amsoil has made changing my oil extremely convenient. Everything I need is shipped to me, and usually only takes a couple days. You get the best oil at your doorstep. Thank you Amsoil
Bottom Line
Yes, I would recommend this to a friend.

My 5.3 Chevy drives and sounds smoother for 216k Miles

Used a engine flush before swapping over to amsoil since I have rough 216k on the clock in my 06 Silverado 5.3 and it’s made my truck seem to drive smoother and a bit more responsive when I accelerate off the line. Time will tell if this oil and proper maintenance can take me to 300k!
Bottom Line
Yes, I would recommend this to a friend.

I use Amsoil in all my equipment from the cars, diesel trucks, tractors, 4 wheelers, and zero turn. They have a lube for everything. I use the high mileage oil on the Nissan rogue to keep it running smooth and the wear down.
Bottom Line
Yes, I would recommend this to a friend.

The Very Best
By

I have a 2011 Cadillac CTS-V in great condition. In order to keep her that way I choose to use only the best products and parts. The foundation of her fair is the motor oil and gear oil I use. So I only use the best AMSOIL.
Its really too early to give an evaulation of this new product, as it has not been in this engine long enough to tell much. While I have used amsoil for many years and believe it to be among the best of the synthetics, its does not seem to change much in the performance of the 5VZFE in this truck.
I am wondering why the high performance filter is not spec with this oil.
Been using this in a 2002 Tundra. Doesnt burn a drop/. At 10K the oil still is straw colored not worn out/ I usually replace at 8 to 10 K. No problems for the last 50K.
I've used Amsoil for years with unbelievable results. My 2007 Triumph motor cycle is getting close to 100K miles and the valves, which call for valve adjustments at 7000, still doesn't need any valve adjustments. Now I just bought a 05 Tahoe, and changed the oil as soon as I got it. I just wish it had a steady diet of Amsoil through it's life. And now I have to hope this High milage formula will make it so it runs for many years to come.
