Have an '87 Suburban that used to get 16-18 highway but now it only gets around 15 but it has 200K miles. I would even guess 12000. It gets between 17 and 20 mpg on the highway. Will find out this weekend when I stop by his auto repair shop over an hour from me. I talked to the guy I'm buying the truck from a few days ago and he claims it's about 13,800 Empty. One custom tune may perform great in hilly terrain but lack efficiency for flat country.
The front hip room is 60 inches and the rear room available in the extended cab is 64. You can probably register it at a heavier weight, but that'll need to be weighted against potential extra cost in taxes, licensing, regulatory fees and insurance cost. The temperature and atmospheric pressure changes can have an effect on engine performance and even if you get your fuel from the same station it can be different in composition from the previous tank. It has 360 ft-lb of torque at 1,800 rpm with a 4. What are you going to use the truck for? The 6-foot-6-inch bed comes with a 25-gallon fuel tank and the 8-foot bed comes with a 34-gallon fuel tank.
There can be some error in this experiment when the testing is done on different days and with a new fuel fillup. My 81 tipped the scale at about 4000lbs, while my 07 runs about 5300lbs. As best as I can remember it got about 10 in town and 12 to 14 highway. In my opinion of course. Oh yeah, there's one more limitation imposed by science. However, these experiences do not mean you will also experience a change in your mileage.
So, you're total cash output for this truck is not as high as you might think. And welcome to the site. Obviously you want to get this cost as low as possible, but i think 5% is a reasonable number. So I might be backing out of buying it so I don't lose anymore money. I can not give the exact numbers I have thrown out my mileage book for my 1976 Chev Scottsdale C 15 pickup. The thing to look for in these kind of tests is a significant step change in your normal readings before the change.
They change every day and that is a fact. I have noticed that throttle position determines mpg more than engine rpm's. I'll bet that would help with what the guys were saying about lowering the bumper and making sure your air dam is installed. The 21,000 pounds sounds a little on the heavy side. It is available with a 6-foot-6-inch or an 8-foot bed.
It's nice to do these types of tests and trying to keep all other variables constant is very important. Or does anyone have a similar setup and knows what it weights? So what can I do to get better gas mileage? The gas mileage has not improved much since the 80s, but the engines now make about twice as much power and hare heaver than they were then. Thanks again for your guys help with this truck. The 1997 Sierra has a standard five-speed, manual transmission with overdrive. It's even a lot cheaper than that if you have natural gas at your home. However, you can improve your fuel economy by installing a lip on your bumper and extending it down almost to the ground.
I got a copy of the title and it it says the unladen weight is 21,000 pounds and gvwr is 25,500. Track how much you spend in food vs. We all do want to get better mpg though; You may want to check out my in depth mpg thread, which i admit i have updated in a while. There is a relationship between air filter restriction and mileage. There are many variables that affect mileage such as: tire inflation, the type of fuel, weather, elevation, the speed at which you drive, the gear in which you drive, the speed with which you accelerate, engine maintenance, excessive idling, cruise control, the grade of motor oil you use, and of course, the condition of your air filter. This engine has a 3.
What do you guys think it might weigh? You can gear a vehicle to be ideal for flat country, but it's efficiency will suffer in the hills. Hi, I just recently put a down payment on a 1987 gmc c7000 rollback. They'll also tow more, last longer before needing a rebuild, and are 100x more comfortable. I am not saying you can climb a hill at redline without effecting fuel consumption. Now what do you think that will do to your mpg? I would even guess 12000.
