Are there any aftermarket antifreeze brands that meet the requirements for the 6.0 PSD?
Ford's Premium Gold antifreeze is spec'd as "VC-7-B" and is a long-life coolant. Just becuase others claim to be "long-life" does not mean it meets Ford's specs for this motor.
The 6.0L uses this special fluid and does NOT need additional addives like the 7.3L motor did... so there is obviously changes and improvements to this spec that our motors need.
Here is the front and back of the Ford (factory fill) coolant for our motors. The back view show the spec... so just do a search on the internet or look at coolant bottles when at your favorite retailer or auto parts store.
I paid $10.00/gallon at my Ford dealer when I flushed my system at 50,000 miles... but then again, I wanted OEM coolant and benefits... or at least perceived benefits as I see them.
