I have a 01 ECSB 4.8l with 125k. Am getting a little coolant in oil but very little per oil analysis. This might be an easy fix but am looking at it as an opportunity to upgrade. If i want to go reman where have you gone? Want to get a 6.0l but found a new 5.3l L33. Not going to the track and pull boat like less than 20 times a year. Would that 5.3l HO get close to same mileage as a 6.0? I think some of my fears are with the reman and am liking "new". THoughts

 

It would probably get a little better mileage
