Yes, motorcycle oil is more expensive but they only hold a quart or 2 instead of 8 quarts like my 617 engine. So it still costs less for a motorcycle oil change.

Sorry PEH, but you're way off. While I've never seen a m/c hold 8 quarts, 4-5 is typical. My old Honda CBR 600 held more oil than our Honda Civic! Add the inflated cost of the oil filter and the motorcycle was ALWAYS more expensive to do the oil change on. I've been driving motorcycles for about 15 years and I've never heard of a motorcyle holding only a quart or two of oil. Of course I'm not familiar with bikes built before the 1970s, and Harleys probably hold only a couple quarts - after sitting and leaking for a couple of days.

L.I.B.

I stand corrected. Here's a diesel-electric motorcycle:

What will they think of next?

I've said it before,and I'll say it again. I've logged millions of miles on diesels with plain old engine oil from any major brand that's on sale. If you have a Detroit Diesel, Cummings, GMC, or anything else that fits in an 18 wheel tractor, then go for something like DELO. I change it every 5,000 miles. If your going to putz around town, you should get a gas rig, because a diesel won't last long no matter what oil you use.

Huh? I must have missed the transition ... diesels won't last long round town? Pretty broad statement ...

Not sure the diesel actually knows where it is ... no problem understanding advantages of consistent RPM, etc ...

Sure have been a lot of MB diesels in use as taxicabs the world over - for say, like 40 years or so. I have seen many with over 500K km on them.

George,

Question. Can you verify that 500KM on the clock includes original non rebuilt engine? Comment. Even if the answer is yes,these cars are never shut down. They are not started every few hours with cold oil,cold cylinder walls, and cold pistons. Compression integrity is retained by gas going around and behind the rings which forces them hard against the cylinder walls. This constant pressure causes wear on the cylinder walls. Where do you think cylinder taper comes from? A car cruising down the highway on the other hand has the rings barely scraping the walls. I would buy a high mileage freeway car any day of the week over a low mileage around town car. We are not even talking wear and tear on brake bands and clutch packs in the trans. Once an auto trans is locked up and on the road, it is just moving fluid. Check the owners manual of any brand car you choose, and I believe you will find short trip driving as severe operating conditions. Gas engines run about 150 lbs compression and diesels are more than twice that. Imagine the terrific forces on those rings and walls.I'll stand by my original comments. I to have ridden in cabs in France and Italy, etc that were diesel. I have no idea about the status of the cars other than they were diesels, because that was the cheapest way to go. Taxis in Europe are diesel not by choice but by economics.

Peter

Peter,

Your comment make it sound pretty black and white ... no room for argument, I guess.

I'm out.

I probably should stay out of this. But...
Why are there so many diesels running around on, YES, their origional engines with 200k to 300k miles on them if they aren't supposed to last that long? I've owned at least two diesels that had 300K miles on them with, YES, their origional engines. And I'm sure there are many others in this group that can say the same. Seems kinda narrow minded to say they won't last that long PERIOD, END OF ARGUMENT. Come on.

I seem to have stirred up some sentiment here, so I guess I need to defend my position. First I never said a diesel wouldn't go 300,000 miles. I've seen many including my own go that far. I was probably to harsh when I said that an around town diesel wouldn't last;I was trying to save key strokes. I probably should have said that the odds were heavilly against them lasting. Also I mentioned that a taxi falls into a different category because it is almost never shut off and started cold.Moraine just made note of that. I just spoke with a long time friend of mine last night who has #2 diesel fuel for blood. He was a line mechanic for Mack truck for 10 years and finished to retirement with Mercedes. He bought a 200D many years ago from some people who used it around town to check on their apartments. The car had 40,000 miles on it ,and he had to rebuild the engine because of excessive cylinder wear. He put 160,000 miles on it as a commuter. The engine was still fine, but he pulled it to install a 240D he rebuilt. He gave it to his wife to putz around town, and they did sometimes drive it to Florida. After 80,000 miles the engine had such wear that you could hang a finger let alone a nail on the ridge. On the other hand I've seen engines with 200K or 300K freeway miles where the cyls were like new. I once had a clint in his 50s who wore out one diesel,and when he got his new 84 300DT I kept tweaking the fuel delivery on his pump per his request until I was scared he'd blow the engine. Whenever he got in the car, it was good for at least a 50 mile drive on the freeway. He sold the car with over 200K on it, but even at that mileage,he still barked the rear tires every time he left my place. With all my years of experience with diesels,the short distance units just did not last as long as the freeway,beltway,expressway,turnpike,or whatever ones. I suppose if you only get 160K at 9K a year then 17 years is a long time. OK. Now it's your turn,guys. Come on. I can take it. Someone once told me that arguing with me is like wrestling with a pig in the mud.EVENTUALLY YOU REALIZE THAT THE PIG LIKES IT.

Nah. Format and opinions are too black and white even for me.

Then, I am correct.

Correct you say? That must be about arguing with a pig in the mud. Of course the pig likes it, that is his home turf.
I think there are lots of us that just like the old deisel sounds. Maybe we have been breathing the fumes too long, but they do have their advantages. I think either you really enjoy them or you just don't see the point.
Still in all many of the members here have driven lots of cars and the MB deisels are putting on a lot more miles than the rest. That has been my experience.

A large amount of stop and go driving for short (less than 1 mile) distances without ever letting the engine get fully up to operating temp and/or the same conditions without the oil cooler covered in the winter will ruin any engine from acids and sludge in the oil.

Diesels will also soot up terribly if run at low load all the time.

And, if you follow the recommended 7500 mile oil change intervals while driving under these conditions, you will rapidly ruin the engine. The answer is, of course, to change the oil every three months and do the maintenance as if you were in "severe" driving conditions.

This is why I made sure to drive my car, at least once a week, until the engine was up to operating temp, then another 20 min or so while I was in graduate school. Managed to get 135,000 miles out of an Audi Fox with no special oil changes, etc -- the body fell apart. Engine ran fine.

There is some effect from starting the engine, but it is usually very minor -- MB doesn't use "sharp" rings, so wear is very minimal, since the turbos spray oil, as soon as you have oil pressure you have more than adequate cylinder lubrication. Soot buildup and oil ash probably cause more trouble than anything, both curable by a hard run once week or so.
