I see you are still spewing this crap wherever you can. It is true that an oiled filter will allow a small percentage of dirt through the motor. The problem with your argument is the fact that those little particles are so small and negligible that it's not even worth worrying about. Any dirt particles that make it past that filter will be instantaneously incinerated the moment they reach the combustion chamber thus removing the risk of damage. Not to mention, what do you think the purpose of the oil is for? That aids in helping to catch the said particles that everyone makes a big deal about.

The cap gives you 20% better gas mileage. You can't do that with tire pressure alone.
Tonneau covers DO increase gas mileage, you can think they don't all you want, but they do.

Unless you can prove these numbers you are coming up with, everyone here will continue to look at you like you are a complete idiot. When I mean proof, I'm not talking about what ole Joe blow did on his weekend beer run. I'm talking legit scientific proof where every possible variable has been removed. No guess work, No excuses.

Tonneau covers ARE better. I will not try to force one on you, but for gas mileage they are better than an open bed
You are stupid, I can not prove my point to you and I will not try any further. Actually, I lied, yes I will.
Here is a link to the bed cover, it is expensive, but so are LEER covers. The bonus is you get better gas mileage. The man making it is hoping Ford will buy his idea and try to get all new trucks to have one or at least make them an option.

He has noted 20mpg to 24mpg increase traveling at 70mph. He has numerous threads on that site, with Cd test to prove it. The guy has done his homework.
All I can say to you sir, is you should know your facts, or at least read some on aerodynamics. You are ignorant, yet you feel the need to say that I am wrong.

I have read every single one of your posts in this thread, and you have yet to post up any kind of evidence that supports your claims. You're the first one into to argue, but you can't produce anything to back up your claims.
I'll give you the fact that a sloped cover does improve fuel efficiency, but those completely defeat the purpose of a truck. People buy trucks so that they may have a nice and handy place to
HAUL items. If that cap is so wonderful and helps so much, why is it that truck producers in this world aren't employing the same technology? The answer is simple. Trucks are built with a bed attached to them, and they are put their to be used. It's not looks.
You really shouldn't be talking about aerodynamics as if you know a thing or two about them when you post up that tonneaous are "better".
You want to talk air flow? Let's do it.
At this point, I think we both can agree on the fact that when an object is moving, air acts like a pliable wall. OK?
If we go by your logic, that says closing off the bed or opening the bed op more (removing or lowering the tailgate), Explain this small video to me.
I do apologize for the lack of embedding on this video, but it is the best clip so far that shows what air's actions on a moving truck are.
You'll notice that when the tailgate of that SRT is up, those ribbons will quit moving. Why is this? This phenomena is caused by air being trapped in the truck bed thus reducing drag. Drag is what we do not want on a vehicle.
When we open up the bed, air will move freely through the bed, and we have an increase in overall drag declining our fuel efficiency.
As much as I hate to use the Mythbusters as my reference point, they are by far the best explanation of what happens during air flow.
This is Air flow simulation videos that prove my point further.
At this point, I think and could almost prove that you take every product manufacturer's word to heart. You believe everything they try to sell you, and that my friend, makes you more ignorant than anyone else involved in this thread.
I truly wish this world had more people like you in it. If you can latch onto what companies that make covers tell you about increasing mileage, then I could make millions selling you my new invention-
Laramie's Magic Fuel in a can!
Just simple put one can of this product in your gas tank at every fill up and expect a 500% improvement in MPGs.
Note, I have no scientific proof that this will work, and that I am not liable for any damages occurred during this product's use. These claims are based on opinions only.

Once again, instead of telling people that they are "stupid" or "ignorant" what ever your foul degrading term may be today, give us some REAL proof that backs your statements up.

I have an Auto, 2003 Dakota Quad 4.7 V8, I just bought from my brother
So I have come to the conclusion that the following may help from the consensus of other forum threads.
K&N Filter
This is my primary question, would I be smarter to get the whole intake system or just the drop in, some people report a +1-1.5 increas putting these in, and I was just about to order one last night until I saw they have complete systems in the $100 + range, wonder if that is any better, then I read people saying do NOT get K&N because it lets more crap into your engine and then the oil goes in as well and mess up the MAF or MAP (I dont know what that is)
Switching to Synthetic Lubricants
I read one guy in a thread who kept stating he realized a 2-5 mpg gain when adding synthetic lubricants, however he kept mentioning red line specifically I almost wonder if he has a stock in the company, and he was talking more specifically about standard vehicles.
Changing plugs
I dunno where I begin on this, I read that everyone that did this were not impressed and switched back to the factory ones as their mileage actually decreased.
Removing weight
I have read some people have removed something on the truck that is typically very heavy and replaced it with a electric version that is much lighter, I wanna say it is the clutch fan but I assume that would only apply to standard vehicles.
So that's all I know, anyone can help me out tell me if the full KN system is worth it or the drop in or if what I read was true that some sensor will get screwed up in the long run.
I have tried to adjust my habits, and do as much coasting as I can, and I dotn drive like crazy, and I will be adding a soft tonnaue cover when I get it from my brother. It is quite a shock to go from averaging 17+ MPG in my old S-10 to seeing 13.1 avg on the onboard mpg calculator, (MY s-10 I would divide the miles I got of the tank by how many gallons I just added)
Any insight?

Just so I can't be accused of thread jacking here....
OP, here is my thoughts on what you are asking about.
1. The K&N Filter.
Commonly debated, but in my past experience, a nice higher flowing filter is nice, but produces gains so minimal that if horsepower is the reason for buying one, then you might as well move along. In my testing, higher flowing filters and tubing will actually hurt your top end torque. In other words, you will lose some of the acceleration capability at the higher end of the RPM spectrum. My point here is buy a K&N for the filter savings cost alone, since oil filters are considered lifetime filters, and will pay for themselves within the third paper filter change.
2. Synthetic fluids
You can never go wrong with switching to synthetics. Don't expect MPG improvements, but reap the benefits and comforts of extending your fluid change intervals. Some people may tell you that you shouldn't make this switch on a motor that has a good deal of mileage on them due to leaks occurring. Experience once again steps in and tells me that this is only true when there is a hidden issue that the sludge left behind in conventional oils has been covering up.
3. Spark Plugs
Most motors perform better with standard run of the mill, plain Jane, copper plugs. Makes sense considering that these motors were designed on them. Very rarely will you catch a motor designed on coppers running better on any other kind of plug.
4. Removing weight.
What you are hearing about isn't really focused on weight, but rather freeing up a few trapped HPs. Since the cooling fan is engine driven, you can deduce that the clutch and fan will draw some of the HPs down. By going to an E-fan you gain back those 1-2 HPs that you loss, and you reap the benefits of having better cooling abilities in the heat while sitting still.
As others have told you, your driving style is the largest variable on your MPGs. Easy accelerations and not exceeding 60MPH seem to be the best ways to help your fuel consumption.
Something about how you drive that you might not have caught onto by now. Your mood has a lot to do with how you drive. If you're angry, or anxious, you will probably tend to make harder accelerations and travel at higher speeds. This at least holds true with me.
Another major thing that you need to think about is giving your engine a nice little tune up. Fresh oil, new plugs, new plug wires, new cap and rotor (if applicable), most importantly, GAS.
Not all gases are created equal. I've found that the additives that fuel companies add to their gas act differently between different brands of vehicles.
When I first got on this forum, I was getting about 10-11MPG. After a tune up, I was getting 11-12 MPG. After I ruled out any other engine malfunctions, I started watching where I was buying gas.
Up until that point, I was gas buying mutt. I'd price shop and get it where ever it was the cheapest/most convenient.
I started to wonder what different types of gas would do to the fuel consumption. After testing out every single company in my area, I found that Shell gasoline works the best for ME by seeing that my average MPG was/is bumped to 14-15. I'm not saying that it will be the best for you, but rather, I'm saying that you need to test out different "brands" of gas and see which ones work better.
