Glad it was just the turbo! Just curious (I am not now nor have been in the past a semi truck driver) why it is run with the oil down a half gallon for 3 weeks? I would expect it be topped off more often than that.
A semi truck will (depending on the engine) take up at least 10 gallons of motor oil, so being down a half gallon isnt a big deal.Glad it was just the turbo!

I am a licenced HD mechanic and specialised in engine repair for 35 plus years and a Diesel engine does not run away. I have seen them with the CAC completely full of oil and it shut the engine down to the point it would not pull on the flat. I have worked on the 2 cycle Detroit's to the most modern electronic engines it does not happen.
A diesel engine is compression ignition and any oil brought into the cylinder, will pre ignite before top dead centre, and cause the engine to absorb more Power than it can produce from the fuel injected because there is no longer enough oxygen to run the engine.
These stories are great, I have sen engine cut in half never from it over speeding. An engine will run to a phenomenal RPM. I have seen fuel dilution so bad it blew out the dipstick no run away. Blowers on the Naturally aspirated 2 cycles passing oil no runaways
You all have a nice day!
I'm not saying Wikipedia is always right, but it agrees that diesel runaway is not a myth. Diesel engine runaway - Wikipedia, the free encyclopedia

Thanks for the compliment!Nice to know there are other professionals out there that "get it". Nice job.
Any chance you're in this video somewhere?

Thanks for the compliment!
As far as the video...
Not me..., I am in it for the money, not the glory. Besides, that is the top 1% of the top 1%, so I probably wouldn't have even made the cut.(first 1% would be extremely lucky, might be able to bribe my way into that, lol, second 1%, ain't going to happen!)
I do see something I thought "out of line" with their testing methods. The poor little duck catches all the tires, but in a real world situation, it's not the tire that you worry about hitting something, but the front end which sticks out a few inches further than the tire path when making a turn. Teaching people to be able to judge something that close, and then they hit it anyway(???)if it happens to be as tall as the bumper or higher. I would think using something skinny and taller like CB antennas instead of the shorter ducks would go further to promoting good driving habits, while still putting some challenge into it.
Bottom line, some good drivers, no... make that some great drivers there!
