i switched to sytetic mobil 1 at 126xxx miles, runs alot better and the oil is still clean im lovin it, yes i also add restor in a can also, that stuff works !!!

 

I have heard of a lot of peple running seafoam on the Mustang boards. Most of them say it works. I've personally never tried it. Not sure if thats what your talking about or not.

 

same stuff...basically.

 

I have used the restore stuff too, and I believe in it. I switched to the Mobil 1 synthetic 15K oil and a Mobil 1 filter...good setup for me. Last oil change I added a quart of Lucas full synthetic oil stabilizer. Go talk to over-the-road truckers...many of them use Lucas products, some start when the rig is brand new...they say it can drastically improve engine/tranny life. It feels like it definitely loosened mine up a bit, and also took care of a minor consumption issue.
