Cooler Coolant

[Beatenbo]

I have read several post on runnin' hot. I am so blessed with my coach. I have a MCI C-3 and acording to the final vehichle record it came with 8V92T. 740 auto. I would assume it has largest radiators. However when I bought the bus it had been changed to 6V92T. On a normal hot day 85-90 it runs 175 degrees in  95+ it will run 180 all day at 70-75-mph.Came up Black Mountain,NC 6% grade 6 miles  92 outside at 180 degrees.  All that to say this....It has the red long life coolant the previous owner used and he told me it made his coaches run cooler. Another lesson I learned NEVER run more than 50/50 mix. More anti freeze is not better. I decided to change on my last bus and I just drained and put in 2 cases new (12 gal) ran 10 degrees hotter the next summer and I couldn't figure why. I busted a hose and lost coolant on a trip. Replaced hose filled with plain water drove home 10 degrees. cooler. Put in 50/50 stayed 10de.cooler. I'd like to know if any body else runs the new red color long life coolant.

What brand of red long life coolant are you using?

Gumpy, I don't know it was in the bus when I bought. It is not Zerex like the old red. This is the stuff they put in the new cars. I am going to check my supplier. I need to keep a gal on hand if I need to add al bit to mine.

I have a new Jeep and the coolant is red.
The manual calls it NOAT.  And it's not to be mixed with other collant types.
I haven't yet bought a gallon to take with us, so I don't know the cost.
