About exactly my commute with the same results except I am basing my numbers on what is shown on the dash.

And I thought I was the only fool driving 100km each day to work in a V8 truck! I've considered (and been advised) getting a little commuter car but I LOVE this darn truck. It is depreciating rapidly with the miles I am putting on it but I've decided I don't really care as I am going to have it till it is old old and then it will stick around as a third vehicle on the farm.

Since there are a lot of Canadian boys here - do you guys do anything for rust control like Krown on your vehicles?

 

Nothing more accurate than the old hand job!

Mileage/gallons.

Fill the tank up. Reset the trip odometer. Drive where you need to go. Then fill up again. Take the mileage from the trip odometer and divide by how many gallons you just refilled with. That's your mpg for the trip.

 

I don't know...I have the same truck as you and get the same numbers (16-18 L/100km). I would gladly pay $300 if I could increase the MPG by about 5-10%.

I was in the same boat as you though. Always seems that people are saying "Oh that's strange I get better than that". Even the dealer kept saying it was strange...but of course they can't change anything. So it is what it is

 

It always makes me laugh when people report better fuel mileage after a program. The reality is there are NO gains to be made by changing the factory tune and any improvement you notice is either in your head or the result of a change in driving conditions or habits.

People, auto manufactures spend BILLIONS with a "B" to eek out incremental fuel economy improvements in their cars. Marketplace and regulatory pressures are squeezing them to produce ever more fuel efficient models. Do you really think a $200 programmer is going to do what they weren't able to? Come on.

 

I agree 100 percent, the only way you are going to get gains is to remove emissions crap.

 

Yeah, but manufacturers can only strive to be as efficient as possible while still maintaining safe, reliable, "work anywhere for any type of person and lifestyle" factory tunes. A one-size-fits-all tune.

Meanwhile, for those of us that aren't satisfied or want just a little more, custom tunes are available that contour factory tunes ever so slightly to give us that small improvement.

If we could order a truck from the manufacturer with a customized tune, don't you think they could deliver that mean machine devoid of other restraints and compromises?

 

Sure they could. Go ahead and tune your truck for 100 less HP, you will see some fuel economy gains. But if you believe that you can "tune" your truck to produce MORE power and better fuel economy (without removing emissions devices), I've got some magic beans to sell you. The laws of thermodynamics are not adjustable with a tuner.

 

More power means less work for your right foot.

Advancing timing produces more power from every drop of gas. It doesn't CONSUME more gas.

And having more power means it takes less effort(gas) to maintain speed or accelerate.

 

Yes, that's the secret to fuel economy, more power and advanced timing. Do you mind if I contact the Big Three with your breakthrough discovery? They might want to borrow your magic tuner box.

 

So now we're getting into vehicle applications and purposes?? I thought we were talking about the f150.

Sure, a compact car is small, light and utilizes a small motor which requires a lot less gas to do what it needs to.
Our trucks on the other hand are designed to tow and haul a lot of weight on top of being a passenger vehicle.
What I was trying to explain to you was engine efficiency. That's key to fuel economy.
But since we're comparing apples and oranges, how does a 505hp corvette still get 26mpg??
