Pullin with the dreaded PACCAR Mx13

I’m not sure what the stuff is that Peterbilt uses when they run it through a cleaning cycle. I had one done under warranty, then about 5 months later I was back and paid for one, then 6 months later I was back. After the cleaning it threw an injector code on the test drive. My dealer leaned on Paccar and got me 6 of the gen 3 injectors.

 

Bingo, it’s the “Biodiesel” is the culprit of the issues. The company has 1 Paccar left, all have had issues. Took them awhile to figure the issues, when they stop purchasing Biodiesel, the issues went away. And they started dumping Lucas fuel treatments in the tanks. I dump Lucas as a maintenance about twice within 10k miles in my ISX.

 

Could switch to 445/50 wide base single drives for some MPG gain and weight savings if you’re going to be replacing all 8 drives anyway. Easier to max chain also if you’re out west in winter. (That will be a bit of a bill either way.) I don’t know if the hubs are different or not. My truck came with 445/50 singles on 22.5x14 on the rear per the door sticker but now has more typical 295/75’s on 22.5x8.25 duals so IDK what happened there. I’d kind of prefer it had the singles on it. These 8 drives I’ll probably run till they’re dead and maybe look at doing either that or just singling out the duals and running the outer aluminum wheels only on 4 new drives.

 

IL has a lot of bio-blend fuel. I avoid it whenever possible. Truck hates it. Yes the wind will be your main opponent in the MPG game. Also cold temps and lighter winter blended fuel hurts diesel engine MPG a little. DEF I don’t know. The boxed 2.5 gallon jugs are a rip off compared to the bulk dispensing at fuel islands. Easily double the price per gallon

got a link for that map?

 

They sell Roadmaster XL premium diesel at the Cenex in Menonomie, but I don’t any discount there so it turns into an expensive tank of fuel. Most Kwik Trips in WI sell Bio free TundraMaxx premium blend and I actually do get a discount there. Petro in Portage has very good fuel and it’s always fresh because of how fast they turn it over.

Loves I just don’t go anywhere near for several reasons, including the fuel. MN fuel hard pass also.

 

Roadmaster XL from Cenex is good because it has additive injected in while loading.

The other places will have the same fuel from the same rack. Just regular X grade diesel.

I’m not sure about the Love’s map. We don’t haul for them so I’m not sure what their setup is in Pacific Junction and Shelby. Either they would have to get some bio first and blend in their trailer or they have an underground tank and blend at the pump. The TA in Council Bluffs has a bio tank and up until a couple weeks ago they hadn’t been blending because the tax credits went away.

That’s the thing with bio and ethanol. If the government stopped subsidizing it then they’d go away because it’s not worth it. But we need to subsidizing the farmers so then we end up subsidizing the bio fuel and ethanol producers and give tax credits to those selling the product to the end user.

 

The Kwik trip premium has a separate holding tank and separate pumps from the regular stuff. They’re clearly marked on the ground. Where it becomes different from the normal #2 I’m not sure.
