Caterpillar and Cummins/Fleetguard both have ELC's-- and all the data I have seen suggest they are superior coolants.
I know my Caterpillar ELC was analyzed this last summer after 4 years and was found to be "as new".

Post refers to these suppliers not Cat or Cummins.

Bill: Here are the Cummins Coolant requirements. Probably much more detail than you are looking for.
Section 3 Extended Service Intervals- goes into the use of those ELC's that were a concern and why. If the ELC you use meets Cummins 14603, or CAT EC-1 there is no cause for concern. Cummins 14603
Hope this helps.....
Edit: Also at the end of the article in the Appendix is a Q&A section discussing the Chevron, Texaco and Shell ELC,s and what action to take if they are in your engine....
