What coolant are you all using? I'm about to get the coolant filter system, and I've heard the international coolant is best to run in this motor. What do you all say?

Just do a search in this section and you'll be reading for days LoL. A lot of good threads about this already out there.

Doing a flush tomorrow, along with some other fun items (Harley lights, aFe intake and HFCm upgrade). Picked up my Zerex ZXED1 from Napa earlier. $65 for 4 gallons. Went to CAT and they wanted $22/gallon, O'Reilly wanted $25 for Final Charge.

I use shell rotella elc-1 no issues

Same here the last change I did, but come to think about it my deltaT is up now after switching from NAPA ELC. Probably not the issue since this is still my original oil cooler.

Yah but I've been running ELC for years but switched to Shell this last coolant change out. (I change mine every two years even though I know I don't need to and it's a waste of money). Thinking its an additive incompatibility issue. IDK
