Fuel Economy

[mhughes165]

lol, no this isnt another thread of people bitchin about what kind of mileage there trucks get, or how expensive there gas is.....


this is about what the epa says ur truck will get, in there new revised number system

www.fueleconomy.gov

i think most people here will be surpised that what they thought was bad gas mileage for there vehicle is actually right within EPA figures for what it should be gettin....

With my 4.0 B2 I made 14mpg in my daily driving. That says 15 city for a '91 Explorer 4.0 5-speed. Pretty close since I run 31" mud tires. But it's not a good yardstick since it's a piece of garbage and I've never changed the sparkplugs in 6 or 7 years.

I just filled up my diesel Chevy today and calculated 18mpg (201 miles, 11.18 gallons). Nothing in there exactly what I have since they don't estimate trucks over 8,500#GVWR, but a 1988 1/2-ton Suburban 2wd is shown with 15 town and 21 highway. The old one was 16/23. My truck is heavier and doesn't have a lock-up converter.

Our Honda gets closer to the old rating. It socks down 22mpg like clockwork and about 18 around town. I think their adjustment was politically motivated.

Yup thats right on the money for me.

I didn't get close to 15 with my F-150 until I hung a grille guard on it, even then it is usually a tad higher. Before I was pretty regular at about 19mpg, now I am closer to 17mpg.

Sadly, their mixed driving rating is about right if not a tad optimistic. A 5000lb+ truck with a V-8 in stop and go traffic can get ugly in a hurry, and a 23 year old driver with dual exhaust doesn'th help either.

LOL !! A 87 2.9L Ranger is rated for better fuel economy than a 2007 3.0L !!!

Now THAT'S progress !!! LMFAO !!!

You can thank the EPA for that one... the "cleaner" they try to make them, the worse they piss away fuel. Be glad you don't own a semi- my '99 work truck did 7 if you drove it like you hated it and 8 if you drove it right. The '04 I have now with the diesel EGR valve does 6.5 or less no matter how its driven. That's progress. The only problems I've had with the engine in over 600K miles is THREE EGR valves and an EGR cooler. Can you say, "downtime"? Sure. Sure you can.

I've heard the new 6.4L diesel is a fuel hog. Runs cleaner but uses lots of fuel.

So, how does an engine supposedly run cleaner but use more fuel ??

It just has a better way of cleaning all that exhaust. Go back and look at the 12v mechanical cummins, they almost always get better millage than the 24V electronics.

I filled up today, 16MPG, little higher than usual, payed 3fucking73 a gallon

You're reducing the more harmful emissions, particularly NOx and PM. You are, on the other hand, producing more CO2.

EGR valves are very tempermental when it comes to long term operation. Their job is to operate in a hot, corrosive environment for thousands of hours. Same thing for EGR coolers which have high thermal stress and fatigue on top of that. Three EGR valves in 600k miles isn't as bad as I've seen on some engines, although the repeat failures tells me that they are working on an improved design as we speak (I hope).

From what I hear, about 13mpg out of the box is normal, after they start getting halfway broken in (40-50k miles) it starts to go up.

Increasing emission regulations and the quest for obsene power figures are the main causes of poor fuel economy, plain and simple.

In a couple years even the 6.4 won't pass emissions, rumor has Ford is building an in house 6.7.

damn the price of oil is still on a rise i hope car manufacturers should find a good alternative for gas. say, what do you guys know about biodiesel how does it affect your car?

let me guess, you're '04 has a Cmmins ISX motor in it?? we seem to be going through EGR valves and cooler for those darn engines like they're free

pretty accurate for my application, though in my buick I get 1-2 better on the highway than they say.

Just looked up my 96' Ranger. I found the old EPA rating is dead on for my kind of driving. I do get 22-24mpg city, 26-28mpg highway. On average between fill-ups, I get about 23-25mpg.

Wonder what my other 3 vehicles are rated for?
