Ain't that the truth.
I often wondered if I put all the gas savers on my car would end up making my own gas.

I'd love to have a joke page circulated in the late 1970s at VW shops (I worked as a VW mechanic back then). It had all those "do this and save X% mpg" listed. Final talley was you'd have to drain 2 gal. out of the tank each week. LOL! And the math checked out!

I have to tell a story about old VW's as a kid we have a neighbor that just talked up the fantastic mileage he got with his VW. Well being kids we decided that we would put gas in his VW at night oh he was beside him self when he was getting 45 MPG--- then we started stealing it he had the thing back to the dealer several times when his mileage dropped to 18 MPG that was great fun!

Maybe its in the gear ratios or the speed you travel if i go faster than 67 the MPG drops like a brick

Fantastic mileage but it's a little slow.

Yeah my other TV is 4WD but it doesn't have a loader so I'm torn as to what one to use when we go camping on the other hand my wife doesn't have to sit in the bucket.

owning a deisel i thought about chipping the motor but could not find 1 bit of proof that it would help MPG the only proof was in going fsater and shifting for racing which im not into

2002 dodge ram 4.7 v8 4x4 reg cab short box on 33 inch mud tires with 3.55 gears
60 on a flat highway with no load 18-21
60 on the highway in the hills no load 11-16
75 on the highway in the flats no load 13-17
60 on the highway towing a 20 foot sunline in the flats 9-14
60 on the highway towing a 20 foot sunline in the mountains 4-9 mpg
stop and go in and around where i live i average 11mpg, very sad, truck hates city driving
these numbers were much nicer before ethanol
ive seen as low as 3 mpg going up graphite mountain in on rt 8 and on rt 2 in the berkshires in the steep sections... ive never seen a truck that will fluctuate so much based on conditions

Not exactly a scientific sample but I observed a 9 mpg value towing our T-2499 down to the dealer with our 2012 F-150 Super Crew Eco-boost. That's using winter gas in the Pocono Mountains in fairly windy conditions. Interestingly enough, I got 8 mpg returning towing a Winnebago One 30RE - a unit that is about 1900 lbs heaver and traveling a route that was more stop and go. Based upon our experience towing the 2499 with a Chrysler Aspen, I'd say that the F-150 will return just about the same mpg.

2003 Tahoe, running naked, 70 - 75 mph, 19 mpg, usually. Flat lands of Florida.
Towing the Sunline, 10 - 12 mpg w/ two kayaks on the roof of the truck. I'm never sure if they help or hinder gas milage. Apparently, they have little effect.
I tow in OD, keeping RPM's under 2000. The truck holds it fine, with little 'fishing' for 3rd gear, except on inclines. Good HD shocks on the truck, and a careful alligning of trailer wheels made a heck of a difference in the ability to hold 4th.

Somehow I missed this thread over the past three years????
Anyway, here goes:
2003 Chevy Silverado LBZ Diesel, 4x4, EC/SB Towing Sunline T-2570: 12-13mpg
Same truck, towing 2005 Sunline F-293SR: 10mpg (albeit at 62mph instead of 65mph)
Same truck, towing 2011 Big Horn (in sig): 10.5-11mpg
New truck:
2012 Chevy Silverado DRW Diesel, CC, LB 4x4 towing Bighorn: 10mpg
I have never used the saying "didn't know it's back there" with ANY of my vehicles or trailers, until now. Sometimes I forget. The new truck is just ridiculous. I find I have to keep my speed in check. The first few times out, I kept finding myself going 70mph. That's too fast. But it feels effortless. Needless to say, MPG suffers. What boggles my mind is that the Bighorn scales at 13,500lbs... and I can hardly tell it's there.
The other interesting thing is that my WORST combination was the Sunline fifth wheel. The flat front must have been the enemy, if I had to guess. You could really feel it hitting gusts of wind, where the rounded front of the Bighorn does not feel that way.
Also interesting is that it seems weight has VERY little to do with anything. Once you get it moving, and provided you don't start/stop a lot, it seems to make almost no difference in MPG.
New truck empty MPG: 14.5
Old truck empty MPG: 17
Though, the new truck is still really new, with only about 1500 miles on it.

Jeff,
Yes you are correct in your thinking. 45mph is about the magic point where the power to pull and drag seems to start eating up the fuel at a faster rate.
I bought one of the Scan Gage II OBD2 monitors and I can program it to read out in HP. Sort of cool to see it change and how much. Once you get the mass rolling and as long as there are no hills/wind the HP draw loaded is not that far off of an empty truck. Again this is a bigger engine doing this. The little engine is working harder so you can see the difference more.
Wind drag just eats us up in fuel mileage. Weight is a part of it but not near as big as the wind drag. 45, 50, 55, 60, mph etc all have different drag and it is not linear. Weight eats us up getting going and wind drag takes it toll keeping us moving. Since we are moving more then up and down start stopping the drag is more noticed.
Do not know if you ever canoe much however in canoeing we have the same problem. Now here weight does affect us more as the boat is deeper in the water and paddle power goes up. My shoulders tell me this all the time…. But then there is the stem of the boat (the point on the front). If you are in a Kevlar canoe the stem if really small, maybe only 3/4” wide. It cuts through the water really easy and the bottom of the canoe is more slippery to the water. Then get in a Royalex (fiberglass and other resins) canoe. The stem is about 1 3/4 to 2 1/4” pending the brand. While the slip to the water is not that bad, the stem drag is for sure there over the Kevlar. Now get in an older Grumman aluminum canoe and while the stem is not too bad the drag from the aluminum is a lot that and the fact it does not have all the profile enhancements of the plastic boats. Again drag affects the power. And when paddling 12 to 15 miles with a canoe loaded with gear, regardless of the make up, once you get it moving keep it moving. The power to get it going again is, big.
Glad your new ride if working out well.
John
