By implied definition, a "Dex-Clone" is most similar to GM "Dexcool" because they both contain 2eha as an active ingredient. Imo, calling Peak Global Lifetime a Dexcool clone/Dex-clone is not accurate. A more accurate description imo, is a universal OAT coolant with similar properities, no silicate, no amines, no nitrites, no borates, all of which are also properties of an Asian P-Hoat. But unlike Dexcool/dexclones, non 2eha PGL also makes it the same as both Asian and Euro coolants in that respect. Perhaps sematics, but PGL being a universal OAT minus 2eha seems a better description. So to answer Best's question, I would give PGL a thumbs up 'if' using the same coolant in both is a priority.
To answer the OP's question, he's dealing with G-05 for the 04 Focus. And as bdcardinal pointed out an Asian P-HOAT (Motorcraft Specialty Green) for the 10 Fusion Hybrid. No matter what he chooses, if he wants to run the same coolant in both vehicles there will be some chemistry difference whatever the choice.
There is Peak Global Lifetime which is a Long Life/Extended Life OAT with all the properties of the Asian coolant minus the P, phosphate. Also similar properties to G-05 but has no silicates as opposed to low silicates. G-05 is another Long Life/Extended Life option, but as mentioned it contains silicates (low) as opposed to none in an Asian coolant. And then there is full strength Motorcraft Specialty Green P Hoat that could be used in both. But last I checked at local Ford dealers, MSG had gotten pricey even for full strength.
Yes. Valvoline (Zerex) is telling me the same thing: To use their same G-05 in both vehicles. However, if there is some chemistry differences, as you are saying (especially in the "10 Fusion Hybrid), can I expect any drawbacks in a real world application? I already have almost 100,000 miles on the original coolant on the Fusion. My first change interval (at 100,000 miles) is supposed to last until 150,000 miles.
Thanks for all the information guys.
