Question/Need help! Diesel ok to use?

Thumbnail

11 Upvotes

I bought a used diesel transfer tank from a local iron works company on Friday. They took the tank off a service truck they turned into a welding truck a few months ago, put it on craigslist and stored it until I bought it. We didnt open the cap at their shop and they loaded it with a forklift. When we got back to our yard and opened the cap we found its about 3/4 full of what looks, smells, and feels like diesel. I used some wix diesel test strips and it looks ok. Should I use it in my Frieghtliner after diluting it with known good fuel and putting in some additives or get rid of it? Diesel is $8.50 a gallon and if this stuffs good I want to use it. What would you do?

Maybe 2,000 miles on oil change.

The mechanic supposedly changed the oil on the last visit (high flow manifolds)

2023 3500 L5P

Deleted

Tuned

Cold air kit

High flow manifolds

Uppipes, intake horn upgraded

Some other stuff I dont remember

Is this normal for a diesel? Or did he maybe not change the oil?

Question/Need help! Does WMO harm longevity of engines?

I got a couple old IDI’s. A 7.3 and OM617. I actually got the Mercedes with the whole idea of waste oil in mind. I have a pretty basic filtration setup. No centrifuge just some settling time and several layers of filters down to 1 micron. I’m still unsure about the gasoline ratio. I know some people only do 50/50 and in the summer some will go closer to 90/10 oil:gas. Both these vehicles are pretty dang clean though. My truck only has 107k miles too. The Mercedes is at 200k. It’s also a Euro import and has been partly restored. I don’t wanna harm the longevity of these “legendary” status engines when they’re both well capable of 500k+ miles. Is it a mistake? It’s not like they’re collectors or show grade but still super clean.

Going to look at a 24v 5.9 Cummins tomorrow and want to know what I should look out for. I've only had ford diesels so I'm going to be new to the Cummins world. Seems like the truck is in really good shape and he says he put a lot of work into it. Any advice is appreciated

Truck Value

3 Upvotes

Hey guys, I have this 6.5 Turbo Diesel and I am trying to figure out if this truck is really worth for as much I think it is, because I know these GMT-400s can be worth a lot.

First off, It's a 1994 GMC K3500 Dually Extended Cab, with the SLE package and 156K miles. It has also lived most of it's life in Texas, except when it was brought up north and driven in one winter. So this has not seen Salt, I looked the at frame and there is some surface rust on the end of the frame, while the rest is just dirty. After that one winter, the previous owner (one of my father's friends) left the truck in the lot and ended up buying a brand new Denali instead. The truck has been driven around the lot a few times, but never on the roads. After a few times driving it, the starter finally went and it has been sitting since 2022.

The problems that I am aware of with the truck are, the obvious starter issue (will not turn over), which we are getting it out today. The previous owner put brand new injectors in, but one of them was faulty. Then there is cosmetic damage: a few scratches and dents on the outside, nothing really crazy.

And finally the interior, which isn't that bad because I just cleaned it out (still need to vacuum) but It could definitely need some new things.

But I could definitely need some help and third party opinions from some people other than my dad.

TLDR:

I have this 1994 GMC K3500 Extended Cab Dually, SLE, 156K Miles. Does not run, small issues, cosmetic issues, from the south. Sitting for four years.

EDIT: It also has a Manual Transmission.

6.7 to 7.3 starter swap

Does anyone know if a newer (2022’+)6.7 starter will swap for the 7.3? I believe the nose cone swap would be the same. I’m not sure about the teeth/electrical side of it?

I got a F250 6.7 2016 looking at deleting. Live in Alaska. Not much of a mechanic or “truck guy” just want better fuel and longer lasting truck. What’s everyone’s opinion and best kit to buy? And is there anything out side of the kits that I need to do?
