What kind of MPG can I expect?

Recommended Posts

Yeah your probably right! Young, dumb and stupid in those days. Probably got more like 25 mpg. I do think the national speed limit was 55 back in the day and now that's what I drive again LOL:-)

When I bought my rig the first owner keep MPG logs, and he was getting more like 16.5 to 19.5 MPG. These looked like legit logs he kept to see what his MPG was. Now this was in the 1980's like Linda said, and gasoline was 100% gasoline. Now I am not going to downplay Ethanol, but I think they should give that to you in a shot glass and put the gasoline in the camper, you know. "here's your gallon of pure ethanol everclear for your kitchen, and here's your 9 gallons of gasoline for your motor home". Go on vacation and come home with a years supply of pure corn mash booze.

I have an 86 Toyota 22re 4x4 extra cab that gets 19 MPG until I put my bike trailer on, then it gets 17 MPG. So If I can pull that trailer with my Sunrader and get 13.5 MPG, and have a place to sleep and cook in, well that's a great deal.

After looking at all my trips and trying to figure out why I got high or low mileage on certain segments of the trip I generally came to no conclusions. Except headwinds and tailwinds which you can't do much about. For every up there is a down, low MPG on the way up, great MPG on the way down. Some of the steepest climbs gave me some of the best MPGs, go figure!  High speed on freeways with headwinds were the worst. But high speeds on freeways with a tailwind were pretty good MPG's. Rural two lane slow roads generally gave good MPG's, even when having steep (slow) climbs.

Ill post this again. I used to drive a 1984 Dolphin, 22r with a 4speed. Bought it with 78,000 miles. Drove it for 58,000. Went to Yellowknife, Bella Coola, Alaska, up and down i5, Utah, Arizona and many other places. 

I got an average of 17.43 mpg. My top end speed was 53mph.

Slow down.

Now driving a 1994 Warrior. It had 36,805 miles on it when I bought it. It now has 79,998 a as of last fill up.  I am averaging 12.443 mpg. I try not to go above 62. Prefer 58. I use OD when I can.

Slow down.

Ethanol has heat value (it burns, case in point it's used in race cars) so even @ 10% you overall loss is not much greater than 3% in a mileage hit. If you want mileage slow down take the back roads and drive 50. Wife and I went to Down East Maine awhile back with our camper up I95 came back home on US 1 a 2 MPG increase over the highway and it was a far nicer trip.

Some mpg food for thought:

1) In addition to staying on top of all other mechanical maintenance, if you advance your ignition timing you'll get both better power and better mileage, just don't advance it so far that your engine pings, or so far that you don't pass your smog check (I'm in CA). Related: if you use higher octane fuel, you can advance your timing further before the engine will start to ping.

2) Aerodynamic drag increases approximately linearly below 45mph, but starts to increase exponentially above 45mph. So, as many here have mentioned: slow down your highway driving and your mpg will improve. 

3) If you can figure out how to shed weight reasonably, this will improve your mpg. 

4) This last tip came from a tire & alignment technician with 25-30yrs experience: Increasing tire pressures by 5-10psi (even going over your tire rating) may give you some mpg gains. This is also counter-intuitively good for driving through the desert so that your tire sidewalls flex less to prevent blowouts. It is the flexing combined with the hotter road that causes blowouts.

Darrel, I have a 92 warrior, I get identical avg. mpg. 12.5-- sometimes I've got 13 and sometimes 12. mostly it is right at 12.5. as far as driving choices, I prefer staying off the interstate as much as possible. I have no urgency to get anywhere anymore. to me the journey to the destination, is just as rewarding as the destination. I want to enjoy the scenery afforded by NOT being on interstates.  slow down, have fun, get there safe. repeat. joe from dover.

Yeah Maineah hunkaman and me are taking our rigs to the Total Eclipse in Illinois. Joe mapped out a route using US 50 almost the entire way. Back roads here we come!

Theres someone on the Facebook group,and it seems like he's posted here with his logbooks,that he's averages on some of his trips 30mpg{4 cyl,not a chinook}and is pretty much always over 20 mpg,posted pics of his logs,Find it very very hard to believe but he did not appreciate me questioning those numbers

Well quit picking on him. He's obviously mathematically challenged. I have 2 RV's that use no gas at all. Of course they are parked.

The bare trucks didn't get 30 mpg

Now you've gone & done it, Linda----I've choked on my chicken fajita.  Now my keyboard's a mess.

I had a 97 Tacoma 4 cylinder the very best I ever did 23 MG granted it was a 2.7 and 4WD but it sat up high with more wind resistance kind of like a Toy home. My 2011 4 liter Tacoma can get as much as 20 MPG hook the camper up I'm doing well to get 13 1/2 The only real way to get accurate results is to fill the tank to the same point every time, after the pump clicks off on my 2011 I still can put another 2 gallons in the tank that's a 10% increase mileage if you don't full it.

The 30MPG poster is really indeed getting 30MPG, he travels 30 miles while drinking a gallon of Bacardi then posts; the MPG is a measurement of alcohol consumption. this is easy to do because he is in effect really getting 40 MPG of gas mileage with his toyota rig in tow behind a prius.
