CMP fluids question ..........

[Bob Carriere]

Oil being the life line of your engine jokes would not be appropriate,

A lot has been written in the past 18 months in USA car club publications to that effect.

It seems that modern oil is really meant for modern engine and the chemical formulationhas changed. A number of car/truck nuts have noticed that particualrly with old engines being totally rebuilt they had trouble with burning lifters, rings not seating properly, etc ... to the point of accelerated wear or total breakdown.

The solution it seems is to use either diesel engine oil or high mileage oil sold for worn engines. These two oils seem to have retained some of the old formulation and include a higher zinc content and other elements that will soften some of the pounding.

Phil Waterman has some very interesting articles on the subject.

I currently have synthetic gas engine oil in my 261 Chev and will be changing for SHell Rotella 15 w / 40 diesel engine oil....... and it will actually save me money on the purchase.

In your case, if you switch to higly fluid synthetic engine oil in your Ford, you may want to check for leaks.
