Well the below post regarding ULSD fuel and lubricity got me to thinking about a few things.
Has anyone noticed a reduction in smog ?
My house is situated on a hill that is shaped like a spur, I am high enough in elevation that I can see well over 30 miles from the kitchen window. A few miles away, there lies the hudson river and I-787, a major route for commuters, besides I-87, I-90 and others close by. I'm sort of on the eastern rim of the hudson river valley. less than 2 miles from the descent down into it and to the river.
I do not see the darker haze that used to settle in by 9am, which was very distinct in contrast. I remember it well in the mid to late 70's, you did not see it on sunday mornings or major holidays. You can see much more clearly than in the past. I use to see the same effect, much larger and more dense in the NYC area, having worked there 15+ years. Not sure about how it compares to today. I've seen it in LA numerous times having been there many times over the years, just not recently.
Fog settles in the same area, its pretty cool sometimes, as its clear elsewhere in the morning but the fog cloud is sometimes real dense over the river.
I can remember if you left an older vehicle, with a carburetor, running near ones house on a calm day, you could smell it inside at some point.
My elderly mother left a '14 model year SUV running in the garage for hours before I discovered it, (thats another story). I had been rehabilitating an american crow that literally had white wings, he was something else to say the least and his roost was in the adjacent bay, and he was still standing!(I was not happy about this at all!) If that had been say a typical GM with a small block chevy, or anything similar, don't matter what mfr., my old '64 F600 292 Y Block, or how many others similar, I can't see the results being the same. It would have reeked in there. I heard the fan on the vehicle kick in, was like what in h$ll is that ??? Odd noise always put me on alert, so I opened the cellar door and the heat was as if the stove was in use down there. The odor,(carbon monoxide is odorless) was minimal and in a few hours with the doors and cellar windows open with a fan going, it was clear and you could not tell. I don't know if it was similar to a confined space situation with bad air, but it was running for hours as I determined later.
I'm not a fan of the EPA and all the government nonsense, as well as many things that are related to what we have today in modern vehicles and equipment, that is another discussion for some other place. I have noticed a significant change is my point, anyone else see it ? Just me ? LOL !
One thing that stood out to me as a kid was the old D7 my father had, which I still have, is that it ran clean, there was no real heavy soot cloud, no real blue or oil related smoke, the only time you could get big plumes of white smoke is if you turned the fuel on and left the compression off or half or somewhere in between, fuel would load up, (probably wash the cylinders) then combust, clear out. You are not supposed to pull that throttle lever up until its ready to fire. When doing that, you'll get a little of each, some white, some soot, but not much of either. The D8800 was designed to run on a variety of available fuel way back when, 30's-40's, they ran clean, cleaner than anything I recall in diesel,(which does not mean much LOL!) as I am no diesel technician or mechanic by any means. So if they could do that with old technology, fuels, oils, etc. why did we have these engines, (ie; mack trucks for example with 5 speed trans) that could make thick black soot plumes, later model caterpillars, and so many others when shifting or changing throttle to speed up or increase power, would get so much smoke and soot ? I remember driving mack tandem dumps that had those 5 or 6 speed transmissions and with a load on, headed up hill, with the wide gap in the gear ratios, I remember watching that thick smoke plume until she caught up. I remember running a tri-axle freightliner, (handle used to be "freight-shaker", 8spd, lo hole and 315 cummins. It was an '87 I ran in '91, hardly a soot plume ever and it was ok on power. It was no match for a 425 Cat as I saw what the trucks could do on hills with that engine, but it was pretty decent overall.
Crazy how its all evolved over time, hopefully we have cleaner air, it looks that way from my view point here on the hill.

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
