Resurrecting this thread
This might be a mistake, but after reading some 20 pages of banter on the topic of using Amsoil and whether it meets the proper specs of Ford WSS-M2C945-A, I thought I would resurrect this thread.
What I can see from reading the Amsoil literature, the Signature, XLM, and OE 5W-20 products meet the Ford specs for the 2012 5.0 litre engine. So, if I am correct, you should be able to use any of these products without any potential warranty issues? Correct?
