Is anyone using Prestone Extended Life Coolant in their Cummins 8.3 ISC engine and is is OK to use or could it cause future problems?

Only use what is recommended for your specific engine. Do not mix. Do not use universal. Do not rely on color. Its more expensive, but, I prefer pre mix. Never have to worry about minerals or mixture ratio. The engine costs too much to mess around.
