How smokey or otherwise is your diesel?
How smokey before you are embarrass to drive the car? All old diesel smokes a bit but how bad is bad? What is acceptable and what is not?

For Example: Bad!
This is what you'd call a bad example:
Mercedes 200D Start - YouTube However, it has sat for 12 years prior to this, and is very badly adjusted / a little bit broken. Also, my neighbours don't care. And if I could get it registered in it's current state, which is nearly impossible in Germany, or anywhere else I would drive it a bit, just for fun.

My 83 SD only has visible smoke at cold start and when floored. 195K mi. That's probably better than average though (I'm lucky there). I think some smoke on acceleration and startup is pretty normal for these.

I suspect my car has low compression I think. Little blow by and oil cap does not dance. It is not black smoke but a slight white haze. It is not a smoke machine so to speak. I just want to get some opinions on what is considered normal or acceptable. All my working ( some are not ) diesels smoke, just a matter of how much.

On a dyno. It's the standard emissions test in CO. Put the vehicle on a dyno, drive at different speeds and shine a light thru the exhaust.

Car had been sitting for over a year, with 311K miles on it: 190D exhaust - YouTube
Not bad I would assume. Needs all new fluids and filters, might have close to no smoke then

When I first got my euro 300d, I was reported for to much smoke. I got a nice letter from the state of California. When I got it, I remember it smoked so bad you couldn't even see the car when you floored it...Had a cop follow me for blocks attempting to figure out a way to pull me over....I liked the attention :-)

My 83 300D T with 298k has no visible smoke from a cold start unless I shine a light on it. Such a sweet running and sounding engine- I love it! Oh I should mention, its last 80k was on veg too. If I floor it when on the road, I see a little black smoke in the rear view, which is normal.

I have noticed that all mine and my brothers cars smoke a little as well. The use of veg oil will cause a little more smoke than with pump Diesel.

Hi Rich, I do not think Veggie or D#2 make a difference. I think the engine are all tired with many many K miles.

*** Today; I sent away a young fellow that came by with a 1992 300D 2.5 turbo, worn out engine (smoking like this when warm) https://www.youtube.com/watch?v=mP8KCp9PJjU it had 800,000 (salt) miles (Chicago/Detroit). The engine uses one quart of oil every 50 miles. Cold start (three glows) with NEW glow plugs, cranking is roughly 35 seconds + the white smoke (unburnt fuel) covers two acres before it builds enough heat to fire. He thought I could fix it with some miracle oil additive, under $100.00 USD. The previous owner rebuilt the turbo, injectors, injection pump, new oil pump, good used crankshaft, new rod/main bearings, new cylinder head, new timing chain and tensioner. I called the shop where the work was done, and they did recommend rings and sleeves, but owner declined "60,000 miles ago". Current Compression numbers dry: #1. 212 psi. #2. 200 psi. #3. 200 psi. #4. 190 psi. #5. 200 psi. Current Compression numbers wet: #1. 222 psi. #2. 210 psi. #3. 210 psi. #4. 200 psi. #5. 210 psi. My diagnosis: Rings and sleeves are worn out, and must be replaced. Doubtful the engine will be repaired due to cost. .
