need better fuel mileage

[brandan250]

i was thinking about purchasing a K&N intake. any input on how i can improve my fuel mileage would be great. also if i get the intake do i need anything else to go with it?

If you need more mpg's BADDDD!!! i would check out the current thread going on about 5 threads below this one. K&N filters are really pretty bad for the engines, stock ones are the way to go.

what he said ! mines coming off if you wanna buy it , lol .

fuel additives like Diesel Kleen and Synthetic Oil can help and it's just as easy as pouring it in. i would look into your trucks strategy and see about getting a pcm roll back and maybe a SCT with a economy or street tune (let the tuner know you are looking for better MPG). if you want an intake look at AFE or S&B. also a free flowing exhaust (i would do the exhaust before the tune or intake)

SCT custom tunes and FICM tuning as well. Good reports from plenty out there but it does matter what your PCM/TCM strategy is currently.

Want to improve MPG on your PSD? Well, the easiest way is slow down. And stay away from city streets. Seriously, I have experiment and it proves over and over.

I have noticed the colder outside is, the MPG will drop. When it gets warmer, then MPG rises.

Try drive less in city, more on the highway. Even on the highway going 55-60MPH will yield 22MPG on my PSD. If I go 70MPH it drops to about 17MPG. That is alot drop when speeding. Lately the weather is getting better, I'm seeing average MPG from 12 to 14. That is mixture of city and highway.

I wouldn't try to modify my Powerstroke engine at all. It is not worth, because saving dollars on fuel can result hundreds of dollars on repairs.

I personally wish that there is no turbo in my PSD. That is because with Turbo, it does decrease the power but it also increase the mileage.

K&N will help but I and others strongly feel that it is BAD for the turbo with good reason and intention.

SCT Custom tunes.
syn 30W oil.
egr delete.
clean your intake manifold from the carbon build of caused by the egr system
cat and muffler delete pipes. This will give you better low end TQ than 4" or 5" but still drop your egt's ~200*.
Fuel cleaner like diesel kleen.
2 stroke oil in the fuel.
FICM tune.

B250, what truck do you have? (specs)

[Twin Terrors]

Properly inflate you tires as well. It sounds funny but it makes a difference

[smokersteve]

It does
