I just filled my tank and got 18.17 MPG. Here is the money I am saving. I used to get 279 milesper tank, yesterday it went 440:

440-279=161/18.17=8.86 x $3.65(what I paid per gallonyesterday)=$32.33per tank of gas.

Your savings will be similar if you slow it down too. So, I guess I save almost 100 clams a month, and to me it is worth it.

So if you put the money you saved in a special account, you would have $600 to put on that dream rifle/scope combo just in time for deer season. Or you could still not catch any fish, but do it with some great equipment.

 

Sorry, but I call BS on that. Throw in a bunch of hills and/or a headwind, and your fuel economy goes down. Couple that with a dirty air filter, and you lose more. 55mph is a myth created during the Gas Embargo of the 1970's. I've heard people calling the local radio station proclaiming the same thing. If 55 saves this much, why not slow to 45?

BS, BS, and more BS.

FYI - I INCREASED my mileage replacing a faulty transmission line and having the proper amount of trans fluid

 

Why are you jumping to conclusions all of a sudden?

And please tell me why you think that driving slower doesn't affect fuel economy. You don't think that higher speeds result in higher wind resistance? you don't think that a higher RPM results in higher engine friction which requires more fuel to overcome? You don't think that by stomping on it to go over 55-60, the engine would run richer then it has to just to overcome that added resistance caused by friction and the wind?

Please explain.

 

That does seem like a suspiciously high increase in mileage for just changing speed. You drafting semi's too? [8D]

I don't think the 55 thing is a myth. It might not have as big of an effect on something that is more aerodynamic (like a car), but hese trucks don't exactly cut through the wind. Next time you are in a pool or the tub - try moving your hand through water so that it "cuts" through the water. Pretty easy huh? Now - turn your hand 90 degrees and move it the same direction you did previously.Is it easier or harder? Now imagine trying to move your hands at 55mph in the water. The resistance adds up fast.

There are so many things that contribute to gas mileage -andspeed plays a part in it. I'm going to call this "Plausable"

55 is a myth invented by environmentalist whackos back in the oil embargo days. I guess you didn't grow up then, but I did. It's a crock of ****. IF 55 is good, then I guess 50 is better? How about 45? What's this "wind resistance" BS? If the operator of the vehicle rapidly accelerates, then more fuel is used; however, less fuel is used for gradual acceleration. The oil in the vehicles and transmissions in today's vehicles are far superior than days past, so there's less friction on the internals.

Todays cars were also designed to operate economically at speeds above the BULL -- **** MAGIC NUMBER OF 55MPH.

Funny how now one gave a shiat about gas prices until they surpassed $3.25/gal. Suddenly, there was a problem

I find that the faster I go, the better mpg I get!

 

No offense to anyone as it may save you a little money although that does seem unrealistic. Anyway If the speed limit is 65mph or 70mph I'm not going to be doing 55mph down the freeway. It just is stupid. I may change my mind the older I get but I believe in doing the speed limit not under. Half the time they should write people tickets for going slow like that down the interstate as they usaully cause more problems that the ones speeding.

 

Wow, hometheaterman. I find myself typing "+1" to your articles more and more.

 

I don't know if it's just me or not, but it feels like the faster I go, the easier my truck moves and the better my mpgs get. At 55 mph my truck is still working for momentum and is sucking fuel. At 75 mph, I am getting 16mpg on the highway, and it times it will go to 18mpg. I like to travel 70-80mph on the highway, the truck starts to float at those speeds and my rpms are around 2,000 rpms. Sadly though, I get about 300 miles to one tank of a fuel. Everyday my mileage has gotten better. I've stopped flooring it since the new transmission, and I'm getting 12.5 city, and 16-18 highway depending on the speed I'm going.

 

gotta throw my opinion out there too i guess. Look at actual road tests. 55 to 70 increases your resistance 85%. The auto engineers desgin our cars trucks an whatever people drive for the best economy in the 40- 55 range. My truck def get better milage at 50- 55 than at 65 - 70. When I am at 55 with cruise my math an consol come up to the some numbers (+ or - .5mpg) 16-17ish. but drops to 13-14ish at 65 70 range on the freeway. an that drafting lol.
