I realize it's been over a year since my last post. I don't even know how to find it!

Anyway, my question is this. I recently picked up a Volvo VNL64T300 day cab and had VoMac do their "standard PM on. I wanted to look over everything they did and upon checking the oil, again, I noticed it was STILL black. Now I know that cars are different than trucks, but BLACK, STILL..?

Any knowledge of this will be greatly appreciated! Thanks in advance

Day Cab:

A tractor which does not have a sleeper berth attached to it. Normally used for local routes where drivers go home every night.

You need to bring the service manager out to look at it. If they did not change the filter then you now have 10 gallons of dirty oil. They would need to change it again. It might be darker than normal but it should not be black.

It's always gonna be black in a diesel motor, with the amount of oil it takes it is near impossible to drain every drop of oil in that engine so the new oil that gets put in will become dark rather quickly because of what was left behind after any oil change.

I know they changed the filters. It looks like there are 3 next to each other and then a 4th on another side. I don't know much about the VE D12 so I have a lot to learn as far as that goes. I have a lot to learn in general, but I really wondered about that. Maybe I'll have another oil change sooner rather than later? It seems whoever had this vehicle before did not take the best care of it. The dealer did a lot to make sure it was ready. All I really have to do is replace the coolant filter and for some stupid reason, one of the rods that attaches the flange to the batteries is missing. Unbelievable, but I won't complain. Other than that, it turns out to be a pretty decent vehicle. Just needs some TLC!

The oil will always be black. If it's not black then you know something is wrong.

Not on a fresh oil change.

Yeah but it'll turn black within a few miles.

It should still have that dark caramel color after a fresh oil change for at least a few miles. If he just had the service done and it looks like it has 20k on it, I totally agree with you Pat, he should question it.

The way I'm reading it, he noticed it on his initial pre trip when picking it up. It might have a couple test drives on it but not enough miles on it yet to leave it looking like it's been in there a while.

It does have 464,000 miles on it, but that's kind of what I'm thinking. I checked it before (expecting it to be black) but after the PM, it would probably have a good 30 miles on it. I wouldn't think that would be enough to turn it as dark as it was. So like I had said before, I'm just wondering if it would be a good idea to just change the oil again sooner rather than later. I just want this thing to be in the best condition it can be in.

As I also had said before, my best guess would be that whoever had it previously, didn't take the greatest care of it. So maybe it needs this. And to be honest, after all the stuff I made them aware of that they kindly ended up fixing in the end, I think it further proves my opinion. They wanted $2,300 (at VoMac) to fix stuff and thats not even including the 5th wheel stuff that the truck sales place fixed for me.

I took the truck and hooked it up to a trailer at my terminal to act as if I were carrying out my regular duties. The 5th wheel wouldn't even lock into place! So they had to replace the springs and the locking mechanism. I am unsure of the correct term. I heard it cost somewhere around $1,000 to replace or get a kit. Glad I don't have to worry about any of that!

But it is running great now. I will be taking it to Chicago tonight for my first trip. Hope everything turns out well!

Terminal:

A facility where trucking companies operate out of, or their "home base" if you will. A lot of major companies have multiple terminals around the country which usually consist of the main office building, a drop lot for trailers, and sometimes a repair shop and wash facilities.
