:P no disrespect taken.

I'm 30. Had my "last day of youth party" the day before my 30th birthday, when I was still technically "in my 20s". We played with foam swords in the park, and Nintendo 64 games at my friends house.
Now its on to grown up stuff...

If you can get 26 out of that big truck I should be able to hit 30 in my little 2wd! There is hope for me yet.

Actually, I haven't been keeping up with updating here.
Since I began regularly pulse & gliding, I have gotten my average up around 30mpg.

So I'm sure you can do it.
You probably won't even have to go to as extreme measures as I have

Hey I bought 87 F250 2wd diesel 6.9L with 4 speed like your. PO say farmer could swap 4.10 in axle but cab on f250 say 3.55.

It seem it too slow on highway. 60-63 mph at 2,500 rpm


What best mpg that huge improve on this? Oh by way it never got hot enough it stay COLD due fan frozen spin since Outside was 10oF here.

PO say t got 18 at 50-55 mph. He never fix diesel leak on Injector's cap so now I need get new cap with o ring for that.

Of all the changes I made, the single biggest difference came from driving slower.

Yes, it lacks overdrive so highway RPMs are high, but is there really ever any need to go above 60mph?

So many good reasons to drive slow: your risk of death drops dramatically, your fuel use goes down (saving both money, clean air, and our country's security), you have less stress - all with less cost in time than you probably think.

See: Neapolitan: Slow down. My philosophy for life also applies to the road.
for my complete essay on driving slower.

As for the heat, our truck has a built in block heater (at least, mine does).
Also, replace stock fan with thermostat controlled electric, and add a grill block.

What rpm your at 60-63 mph with 3.55?

I am worry if mine is 4.10 because 2,500 rpm at 63 is too much while my old 79 F150 with 3.55 It spin 65 mph at 2,300

[JacobAziza]

I have no idea.

Mine doesn't have a tachometer.
And I don't know how to instal an aftermarket, given that a diesel has no coil wire to tap

Darn

Look like we need figure out.

Milwaukee - What size are your tires? RPM vs speed can be calculated from that.
