I am about to hit 170k on my 96 Mustang, and I been looking into doing and engine flush. I saw some Amsoil flush the other day and it look very interesting. I also been looking into taking it to a shop. I been doing some research and I heard that some manufactures don't recommend a flush at all. So what can I do, a DIY, shop or leave as is.
Also I still get good engine pressure it's around 1'o clock if that helps.
