Prestone Extended Life Coolant
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?

A quick look at the specs saw no mention of "for diesel engines". For the best answer, look up the Mil Specs for the coolant in your Cummins owners manual and compare to the Mil Specs on the Prestone produce.
There are basically two types of coolants for diesel engines, particularly critical for linered engines like you ISC:
1. Low silicate for diesels with added SCA
2. New generation OAT-based coolant for diesel
Use even an excellent coolant meant for gasoline or non-linered diesels and you will have cylinder wall erosion.
