This will be on my 2006 F250 6.0 PSD. I am aware that Ford Gold Coolant is specified. I am switching for that reason.
I am looking for an ELC coolant that meets the CAT EC-1 spec. Looks like some have different milage/hours ratings listed on the bottle. I want the most robust one that will have the longest service life. I want this to me my last coolant flush on this truck. I will be adding a coolant filter at the same time.
Is it best to stick with the CAT stuff since it's their spec or is there a better option? The Napa close to me can order the Zerex ZXED1 for around $20 a gallon.
There appears to be several choices;
Shell Rotella
Cat
Zerex
