Viper owners, Probably only applies to track racers since regular street drivers like me run fine with regular antifreeze.
I read about this coolant in Car&Driver. It has no freezing protection but can be mixed with antifreeze. It's only corrosion protection and allows you to run water without rusting your system. It has 50% more cooling capacity than ethelyne-glycol. That means 25% overall since antifreeze is usually a 50-50 mix in your car.
Ordered last week directly from Valvoline 800-teamval, first test. My Dad has a 69 Roadrunner and uncle also has 69 Roadrunner. Both have 440's, one a 6 pack. In Michigan, in August, they puke in slow traffic. With this stuff they are both running 15 degrees cooler and didn't puke during Woodward. It works!
Here's the deal if you are interested. Can only order by calling. Min order is 6 quarts.
1. Get antifreeze out - If you flush system with distilled water, get as much antifreeze out as possible. This stuff mixes fine with antifreeze but the more in the system will reduce the effectiveness. Don't just drain radiator and fill up with this as you won't see much improvement. If you flush with tap water and get all out of block you are good. I don't use tap water in my Viper so I drain and fill radiator 4 times with distilled, cycling through engine each time to get 95% of it out.
2. Drain radiator final time - Mix 1 quart to 9 quarts distilled water. Buy 2 1/2 gal distilled jugs, discard one quart, add one quart coolant, mix up. Fill up.
3. Determine how much water is in block (subtract how much came out of radiator the first time you drained it from the overall capacity) and add straight 10% coolant (not mixture in 2 1/2 gal).
4. Burp hoses, top off, add mixture to overflow bottle, and all the normal things.
BEFORE WINTER STORAGE - DON'T BLAME ME IF YOU FORGET THIS
Drain radiator, add antifreeze, cycle through engine, store car
