Temperature and fuel mileage?

Fri Apr 26 08:02:13 EDT 2002

Hi,
	My fuel mileage increases by 2-5 mpg when outside temperature
increases from 20-30 F to 60-70 F on my '88 5KCTQ. There does not seem to
be much difference in my dash gauge engine temperature when running in 20
vs 60 F air. Is this because cold air can hold more fuel and my engine is
not compensating? Or does the engine temp reading sense non-mileage
related engine region? Or?
