Thanks Greg,
I think I'm starting to understand this. Please let me know if I'm on the right track.
Filter Choice:
Since the coolant is new I should use the filter with slightly less SCA units. My mechanic said I need 18gal. According to this matrix I need to have up to 6 SCA units after 250hrs.
This matrix shows that WF2070 has 2 SCA units and WF2071 has 4 SCA units. This sounds like when the antifreeze is frsh I can start off with WF2070 as I get past 150-200hrs I should switch to WF2071.
Am I getting this right?
Coolant Change
I checked the only manual I have and sure enough it states that at 600hrs I need to flush the system prior adding fresh antifreeze (Thanks a million, Gary for pointing this out).
At this time I just need to understand which RESTORE (regular or plus) to use. My manual says that PLUS contains the double amount of concentration from regular RESTORE. The question is how do I determine if my system is dirty enough and requires RESTORE PLUS vs. regular RESTORE?
BTW, does $16.5 per gal. for ES Compleat sounds like a decent price?
