Poor Fuel Economy - Advice?
Need some advice - I'm getting an average of 13 mpg out of my 2005 GMC Sierra 4x4 with a 4.8L. Truck has 156,000 miles on it. I live in Canada so it's winter right now but the mileage seems pretty low.
Any advice about what helps improve mileage in these trucks? Is this the kind of mileage that others are getting?

'05 Sierra 4x4 - Had 270,000 KM and running well when it was written-off by a stop sign runner.
'94 F-150 from the "F word" company. I'll admit it...good truck. Sold what was left of it for $800 to a guy who came to pick it up at 11:00 PM with cash in hand. Hmm.
'79 Sierra Grande (Black) organ donor - perfect rebuildable 4-bolt 350 and a good TH350.
'76 Sierra Grande (Orange) - hate isn't too strong a word. Kid who bought it turned it into a hot rod.
'68 C-10 R.I.P. - Dad's old truck...too far gone to resurrect.
'59 C-50 - with hoist. Truck is gone, wife isn't. Nuff said.
