B99-ELC Coolant-Royal Purple-Stratapore-etc...
I did the ELC-(Red) coolant conversion. I originally wanted the CAT-EC1. However, I found out the "Mobil-Delvac-1-ELC-Coolant" is the same thing. Even the packaging says "CAT-EC1". From what I was told, Mobil supplies it to CAT... Maybe you guys already knew this? So, sorry if this is redundant.
Anyhow, when the water pump (Airtex) was replaced I went w/ the 203* thermostat and the "billet" housing from "dieselsite" and did the conversion to the ELC. Everything has been operating nicely. The summertime will be the proving ground.
When doing the oil change I switched my filter of choice from the NAPA gold to the Fleetguard Stratapore. Very cool filter, check it out. I continued w/ the same oil I've been using for awhile and have no desire to change. ValvolinePremiumBlueExtreme-100% synthetic.
Also flushed the ATF. I moved to Mobil 1 ATF. Wow, that was expensive. The trans, and the xfer case were done. Yes, slightly smoother shifts. Particularly when shifting out of "park".
Front and rear pumpkins were switched to Royal Purple in their respective weights. Nothing to say except that Royal Purple is a good product, and I had no problem using it. Yes, I did about 8oz of friction modifier in the rear. That's a must.
I wish our fuel filter had a "screw on canister" style. Just thinking... Present design is lame.
Here's an interesting (to me) observation. When you stack up all of these fluids in one place.
8 gallons of coolant
4 gallons of oil
22 quarts of ATF
5 quarts of gear oil
you really get a snapshot of just how much weight you're carrying in liquids...
One more thing, I have been running B99 now for awhile. I get it at the pump. No problems. When using the bio, the Excursion prefers more mild to warm weather... This you'll notice.
