IDI Ford F250 4x4 Diesel Mileage, Fuel Additives, Radiator

I fuel up, talk about Diesel Kleen and Stanadyne additives. I calculate my mileage in this truck for the first time and it turns out to be about 13.6 MPG with a lot of heavy city driving in there, about 80% city driving. I paid $3000 for the truck. I show some issues I have with the radiator and coolant.

I'm getting into more detailed research on diesel additives for lubricity, cetane boost (mileage boost) and all critical factors and considerations. I'll continue to add links to this description as I find them:

@trainwreckmetal ka-choo

we use stanadyne in everything diesel we have. 7.3 powerstroke, dozer, two 7.3 dumptrucks, 2 skidsteers, and a tractor. We don't use it to boost mileage, but because the low sulfur wreaks havoc on the 7.3 injectors and everything else's injection pumps. Its stupid we pay more for the fuel then just put sulfur back in it. Just my .02

@2strokedetroit trying to find scientific comparisons now. best so far is on dieselplace-dot-com. a good way to find that page would be to google 'lubricity study results' im seeing some options there including mixing bio diesel (which I believe itself has high lubricity) i would probably use stanadyne myself except for how readily available the diesel kleen is.

[2strokedetroit]

@maxhauler See we get the stanadyne cheaper because my dad (runs a diesel shop) gets a good deal on the stuff from a part's house (barely above cost). But you need to run SOMETHING in these older diesels to keep the injection pumps and injectors from eating themselves. I have also heard of bio-diesel being bubricritive, I dont have any expierience though.

[maxhauler]

@2strokedetroit Yes that's very important. Older diesels must use an additive for lubricity because the Ultra Low Sulfur Diesel, lacks the lubricity of the diesel fuel which was available when these older injection pumps and injector systems were designed. I plan to do a lot more research on the ultimate fuel recipe, after seeing some new info in the link in the comment above. I'll put that link in the description where it can be clicked on. I'll post a vid when I have a better fuel recipe.

@maxhauler thanks for that link-I'll show my dad and see what he thinks. We have a custom full tank, so I will do the math and account for what we pay for stanadyne (which didn't do bad at all) and compaire it to some of the numbers above it and try to see if it is worth it. Thanks again

@goofyexponent cool thanks man. I just looked and it is C9. I googled a little and I guess that is 3.55 Limited Slip 10.25 inch. (It not's totally clear to me if it could also be a 10.5 inch but that might only be on the F350). I'm really glad to learn it is limited slip. So far when the wheels chirp just a little I only ever hear one side so I was wondering. A burnout video might illustrate the limited slip feature well.

@maxhauler On your driver side door post there should be a sticker. On that it should say Axle Code somewheres with either two numbers or a letter and a number. Two numbers means open carrier, but a number and a letter means factory limited slip. I am guessing "29" or "B9". 3.55 Sterling axle.

@goofyexponent hey man. I'm going to try and find out my exact rear gear ration for you. I'd like to know. I guess VIN can help. Yeah on the ZF5; I have heard of some people getting much higher mileage than me like in the 20s which sounds high but I imagine that implies a manual transmission.
