cj,
We are now the proud owners of an '05 Jeep Liberty CRD. Seems to like the blend well enough, but 75% may be a little rich. It starts and idles perfectly, but misses a little at around 2300RPM. There's a "modification" I found mention of on the liberty forums called "ORM" (Off Road Modification) - that is, unplug the MAP sensor so that the EGR is disabled. Amazing how things smooth right out.
I suspect that running 50/50 with #2 should take care of the 2300RPM hiccups and eliminate the need for the ORM. So, we now have two rigs running around smelling like fried foods!
Keep you all posted if there's interest.
Regards,
Mark
