We do not treat these cars to go 1,000,000 miles!
These motors our very high compression like any diesel and when started cold a vast amount of damage is done. For a diesel to reach its maximum lifespan in means of miles it must be run continuously. All the diesels that go the miles are not started and shut off a lot. Look at locomotives; they are not even shutoff to change oil. Big boats are not shutoff often either and we all know semis make long trips without being shut down. Besides loosing compression when the motor is cold because the valves and rings have not seated you also loose your oil on your top end. For a diesel to go as long it can it must be run for long periods of time!

Perhaps that's why the car with the record for most miles is that M-B diesel that was used as a cab! As we all know, most of the time in Germany those cabs are never shut down. In fact, many times they are shut down just for maintenance work. They are simply kept running as drivers take turns in driving them.

All I know is, my benz is bad enough sitting in it for 2-3 hours and it's a w126 and not as heavily used as a cab (atleast before I got it ) |

Well his ad is extreme. He's got a "buy it now" for $2750. Maybe not too bad. I bet he'd take $2000. cash. You think it'd be worth that?

I think its worth $500 sight unseen, anything more would need a personal inspection.........................

Let's be clear, any car in the world can go 1 million miles or more if you keep throwing money at it!

I don't mean to burst KRAWSCZN's bubble but ships do not keep their engines running continuously. I have worked on everything from 30 ft. shrimp boats to 560,000 ton super tankers and can say with pretty good authority that most shut down the engines unless they are either under way or standing by.
All large ships, except Diesel-electrics, are direct driven, i.e., they have no gear box or clutch. This means that they can't idle the main engines w/o having the propeller moving. Not a good idea when you are tied to the dock. Direct coupled engines start either in forward or reverse. The do this through an air start system distributor valve that selects the piston that is either on the way up of down and applies 300psi (usually) air to that piston. Some older mostly European ships have variable pitch props which allow the main engines to run full speed and the prop to be feathered in either forward or reverse. Still, when manuvering is through the engines are shut down. Newer ships, like many cruise ships, have gone to Diesel-electric. The engines are coupled to a generator which in turn powers an electric motor attached either to a propeller shaft of to 'Omni-thruster' of 'Azerbod' unit. These units look like the bottom of an outboard motor. They can swivel 360deg. This ability has enabled the ships to get rid of bow thrusters and tugs for docking. Regardless of the system main engines are basically not kept running if for no other that fuel costs and wear. When docked the engineering crew usually does maintenance work in the engine room. Having the ME running whiile trying to over haul a gen. engine next to it is very hard, and noisy. You are right in that continuous running is easier on a Diesel than start and stop but big ships non't keep their engines running all the time. |

How often are the big boats shutoff?
I know that when I went on a cruise they left the cruise ship running the whole day when we where on the islands. I am just curius of how long they will sit before it is decided they should be shutoff?

"DISCOUNT GERBILS YOU SAY? Were they abused Gerbils? Were their teeth pulled and toenails yanked ? Why are they discounted?"
Yes, all that, and they were very very smelly. |

I'd say this is the equivalent of selling someone a yearling Thoroughbred and telling them "These horses win you millions of dollars!!! Some have earned over $8 million dollars!!!" Well, he's not lying, it COULD happen. Could being the operative word, and it's geared at people who are very, uh ... optimistic. If your horse happens to be Cigar, Skip Away, Alysheba or John Henry, then great ... but it's more likely to be one of the other 10 billion Thoroughbreds that never earn a nickel.
Personally, I plan to take my car over a million miles. I might have to run behind it pushing really hard for the last 500,000 or so, but ... nothing wrong with a little dreaming. |

I would presume they would shut the main engines as soon as they drop anchor wouldn't they? The generators are already supplying the power to the ship unless they have redundancy with the main engines. I can see why the engines need to be shut off in terms of financial reasons. Those diesels are presumably burning gallons per second so probably with today's realtime technology their accountants can monitor their overhead cost from a wifi notebook! I used to work aboard a 85' research vessel here in LA and it ran two old Caterpillar engines that have been running 9 months a year for 40 years which I find quite impressive. The redline of 1500rpm's and a max cruise (a blazing 10 knots downswell! ) of 1200rpm's does make sense in terms of extreme longevity. The main engines only provided propulsion and were shut off upon docking or anchoring and the twin generators provided power which were run alternatingly (to balance the wear and fuel level in the port and starboard fuel tanks) to provide electrical and hydraulic pressure to the winches. |
