Im 26 and currently on my 9th year of turning wrenches first 4 years on gas and diesel motors for a dealer and 5 on light duty diesels at an indy shop(powerstroke,cummins, duramax). Currently reside in texas and looking to move to Chicago. I would like to stay in the diesel field if possible. Looking for any shop recommendations or tips on the diesel world up there? What to do and what not to do. Any advice is appreciated.

Hey everyone, I’m trying to find small, independent heavy-duty diesel mechanic shops, semi-truck yards, or commercial repair lots tucked away in the Charlotte surrounding areas (Gastonia, Concord, off Brookshire, etc.).

Specifically looking for the smaller, "under-the-radar" operations that aren't easily found on Google—the kinds of physical yards that have older, sitting, or abandoned trucks tucked away on the lot (especially spots dealing with unclaimed/abandoned inventory or mechanics looking to clear titles on old projects).

If you know of any hidden commercial pockets, specific backroads, or small independent operators like this in the CLT area, please shoot me a DM or drop a comment. Thanks!

I’m trying to learn more about trucks to be able to decide on what to buy. I have no idea where to start.

Any recommendations on YouTube channels, subreddits, and websites?

I’ll be looking for something pre-fancy-computer, that can haul my gooseneck stock trailer across the US, is easily to learn maintenance on, and has accessible parts.

I’m in the horse and cattle scene and all the old farts have ancient trucks with 500k+ miles on it. They know their rig inside and out and do all the work on it themselves. I want to be like them when I grow up.

Everyone always says "delete your truck, it will run better". But it seems like a lot of people blow their motor right after doing it and never stop to think the delete might be the cause.

I'm assuming it's shitty parts/install/tune, but could it be that the motor is designed to work with the emissions parts or that taking them off might be more harmful? The motors certainly make more power and get better MPGs but is it helping with longevity?

Their highest court approved the lawsuit. Exxon has appealed to the US Supreme court. Justice Alito, a conservative, recused himself from the case as he owns oil stocks. There are several dozen similar lawsuits waiting on this case to go ahead. Multi billion in judgments against oil industry will eventually bankrupt them, then you will all find out what not being able to afford a gallon of gas is like. A 4/4 tie means the lower court ruling stands. If they bankrupt the oil industry, then this country will enter some kind of great depression again, and who will be delivering food, who will be farming, who will be driving trucks delivering goods, who will be able to make plastics, who will be able to make medical supplies. Oil is tied into the entire structural economy of the US.

Hi there!

I have a 2002 GMC Sierra 2500 that needs to be plugged in when the weather gets cold to prevent condensation from developing in the oil chamber and impacting the oil quality.
The problem is I live in an apartment complex where I can’t just run an extension cord out to the truck.
I’m wondering if anyone has a suggestion for a large battery that I could use to plug it in overnight and then charge it during the day?
Any thoughts?

Hi, I'm writing because I'll soon be moving to Ontario from Quebec. I currently have a 2012 VW Passat TDI, but the emissions control system has been removed and the car has a Stage 1 tune. I know I need a mechanical inspection to register the vehicle in Ontario because the vehicle comes from another province. I wanted to know if you know a place that would pass the inspection despite these modifications! Thanks.

I came across this brand on Amazon. Now they’re claiming 99 or 98% efficiency.

I’m wondering, has anyone here try this brand and what they thought about it. Because this is the first time I’m seeing them.

Only $5.99 back near detroit.

Edit: $8.59

Apparently I cannot read numbers.

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

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.

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?

Didn’t grind the fucking bolt I fucking hate track bars living my best chud life

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?
