Ok I want to get better mileage I went to the pump today per gal $4.25 what can I do to get better mileage I am running 88 & 90 f250 4x4 4.10 gears with zf 5 I have plenty of power 0-60mph wouldn't mind a little less power if I could get better mileage what can I do? One has turbo one doesn't. Both get -18mpg's. My 84 2wd got 22+ all the time probably had 3.55 gears not sure. What do you guys think? Any ideas! I am setting up a waste oil/atf filter to run my oil what ratio can I run that at?

 

Assuming good IP, injectors, & timing, about the only thing is putting your right foot on a diet...
Don't know about how much waste oil...

 

i would say you are doing good at 18 mpg. i have never gotten higher than 19 with my 2wd truck. that was driving in a spirited manner though.

^^^^^^what he said...

 

I have read a lot of people running 50/50 WMO but you will want to start off slow and increase the amount you use until it is either too smoky or doesn't run well with it. I have done quite a bit of research on WMO as I plan to some day run it in my truck. It is easier to manage than UVO in my opinion. You do need to filter the sh@t out if it, though. A centrifuge is best but it costs big money. Personally, I would run the UMO on the truck with the oldest injection system that way if you F something up or get a really bad batch, it isn't as big a loss as FUBARing a new injection system. Watch out for synthetic oil as its flash point is higher so it does not burn as well as dino.

Look into HHO. They are pretty easy to build and people regularly gain a few MPG from it. You could do pretty good MPG with both UMO and HHO. Just keep an eye on your exhaust temps because UMO burns hotter than Diesel and the Hydrogen acts as a combustion catalyst and could increase temps a little. The way I see it, HHO would make the UMO burn cleaner and run better.

Then of course add to this all the other suggestions from people. Don't feel bad, though, I have been getting 14-16MPG mixed city and highway. I have no idea why so low but I have to figure it out. Maybe my timing slipped or something. I'll probably figure it out when I install the Banks.

 

Winter fuel is why.

Winter Blend Fuel - Oilburners.net

 

Ha, I wish I'd be getting at least 14, but 300 straight 6 F150 is running around 11-12mpg since winter started! nothing wrong with it, always been like this.


In summer i've hit up to 17mpg with it on full highway.


Even the Buick is down to around 20-22mpg vs. summer 28+.

 

Yeah I think that between the winter fuel and the wind and rain in the Portland area I am seeing a dramatic decrease in fuel economy I think by running bigger tires on my pickup I will gain a little speed so I can hit 70 mph without being at 2500 rpm. My 92 with 4.10s runs better at speed it has 35s on it. My 90 with 4.10 and 285x75s does ok at speed but I try to stay under 2200 rpm so it does 65 ok I think 4.10s and 35" tires is a good match. I have always been apprehensive about running UMO in my rig still not sure about it though. I think I may need a new fuel filter too and I think that is affecting my mpg too. I want to try the tire swap and see if my mpg improve or get worse I think it will improve, just a hypothesis though. We'll see what works. I'm still open to ideas.

 

Probably a dumb question but do we get winter fuel in Texas? I have yet to see a pump say "winter fuel" on it. Maybe they just don't tell you.

 

you get winter fuel everywhere, but i've never seen it labeled as such anywhere.

 

anybody know what makes winter fuel so that it gets such poor fuel economy?

 

but I really like the sound of the turbo spooling up and I like it when it gives a good puff of black smoke shifting gears

 

its not just the fuel.
9 reasons why your winter fuel economy bites! - MetroMPG.com
and see the link posted in post #3 above.

then you really have no room to complain about poor economy.your bringing a lot of it on yourself.
basically,even the power of the old school idi is more than we should be using under all conditions unless it's required for your load/tow to make it up a hill.otherwise try to pretend you only have 50hp to work with.your economy will sky rocket compared to your current driving style.
that lift and 35" tires.....all points against you.there is much more involved than just reducing rpms.your introducing wind drag under the truck and because the tires are wider,increasing rolling resistance.
pretty much all your doing is wrong for economy.the way you set the truck up,and how your driving it.sorry.

 

i don't know the exact details of what makes the winter blends different, but they're optimized for the colder weather. i've heard that some people have tried running summer fuel in the winter and actually gotten worse economy than using the winter fuel.
