I'm assuming you meant 87 degree thermostat Scott.

Matthew, if the temperature doesn't get high enough the ECU stays open loop
costing you a serious MPG penalty.

The oil temperature may not get high enough to burn off the condensed water
and the unburned fuel from your over-enriched injection costing you a
serious mile per engine penalty.   :)
