Any comments on engine ice radiator fluid? Will it work on a duramax?
What's your reasoning for wanting to run it? The claimed cooler temps? How hot is your truck running? Is it overheating? The factory gauge lies a lot.
It looks like this stuff is popular with bikes, in fact all I could find is bike owners talking about it. The most anyone claimed was a 10* drop. But thats a bike, but those are peoples claims which usually are exxaggerated anyways. Like the guys who gain 8mpg with an air intake.
If you want a PG coolant there are many available, although unless its an environmental concern or you are at a race track that takes your word for it and allows it, I see very little reason to pay extra for a PG coolant.
I don't quite understand why but everywhere I looked they were touting the boiling protection at 265* and freeze to -26*. Those are not really special or stellar specs, its comparable to most coolants out there.
They talk about being silicate and phosphate free which is easy to find (Dexcool is as well).
Just reading through their site it seems like they talk about it being PG more than anything and how special their De-ionized water is. Most 50/50 you buy uses deionized water, its nothing special.
If you just want a better/cheaper/longer lasting coolant than Dexcool, find an HD ELC. I like Delo and use Chevrons Delo line for most of our fluids on the farm. I buy their ELC prediluted in bulk for less than $8/gallon. This Engine Ice stuff is listed for just under $20/gallon everywhere. Delo is rated for 750,000 miles/15,000 hrs/8 years. If you need a PG formula they offer that as well. If you need Nitrate free they offer that as well since Volvo and some others require it for their engines now. All Delo is phosphate and silicate free.
Don't get caught up in a sales pitch, theres only so much you can do to an engine fluid that somebody else can't. Enough of the fluff is just industry standard, nothing too special.
