Purchases with promos

It's nice to have promos. I love the products, but when the promo item isn't sent, it's a little frustrating. I ordered ahead of my scheduled time just to receive the promo item, so when it didn't come.............still love the oil though.
Bottom Line
Yes, I would recommend this to a friend.

Great product! When I first got my powerstroke 4 yrs ago I had a tiny valve click. Used the 5-40 heavy duty diesel oil, tick gone!!! I won’t use anything else ! I used amsoil from my first oil change in my 6.4 powerstroke till now I highly suggest it!!
After trying many synthetics on the market, I got the best performance out of amsoil for my 6.0 powerstroke
Bottom Line
Yes, I would recommend this to a friend.

Been using Amsoil for about 8 years now in various vehicles. What drew me in was the product quality and reputation.
I work a lot in remote areas and don't always have access to power for my block heater. Extreme cold weather starts have been made easier since I switched to the 5w-40.
Used to run rotella t6 but switched to this stuff ever since I discovered the preferred customer program and will never go back! Run it in my powerstroke and my tractor now as well
Many oils are not described about the abilities to protect the engine. Amsoil does. As well with filters like the two sets of Amsoil double filters I have installed on two trucks their filters are far superior in cleaning oil.
Most products sold today are poor quality with advertising. Amsoil has stuck to consumer education and better products. All our equipment uses Amsoil oil and filters in order to avoid other oil company scams.
We removed the 2015 6.7 diesel engine oil pan on a Ford F350 and with using Amsoil the pan inside was 100% clean, zero deposits. A larger oil pan was installed, no engine problems.
Bottom Line
Yes, I would recommend this to a friend.
