How many folks have any REAL clues about lubricity vs. viscosity vs. wear ??
And then, what about gas washing from excess fuel in cold starts; along with high idling due to cold vs. putting a load on the engine at that time ??
Most folks with cars know just enough to get in, turn the key, and zoom off UNLESS they are wimpy about their own cold exposure & thus prefer to have a warm car to get into.
Any article that claims authority & says that very few cars have engine failures is fulla baloney; our mechanic basically makes a whole 2nd salary obtaining clean cars with burned up engines, putting in a good, fully serviced engine & selling those at a profit.
Is this just as true in much warmer climate areas ?? Probably less of it...and why:
The lubricating oil flows more freely when it is warmer, especially when the owner gets it changed maybe once a year whether it needs it, or not (yuk, yuk, yuk)((Worn out engine oil is much thinner...)).
Right now - this minute - here - it is around -16°F with a wind chill as low as -37.
The adjoining unit had a pipe burst earlier WITH plenty of heat running and we'll have no running water here until that gets fixed - so we know just a wee bit about living with real winter conditions.
Our cars have ~150,000 and 220,000 miles on them - and they get warmed up until their idles come down;
PERIOD.
They also get regular engine oil changes & other regular maintenance as needed.
Also, right now both have battery conditioners connected so as to have the best chances of starting at all after such a nice, chilly overnight.
The mis- and dis- information about this topic provides a terrific derailment to the ignorance of the sheer waste imposed by folks choosing to drive ever-larger, wasteful monster-sized vehicles, but even better still...
Most folks know NOTHING about the relationships between huge fuel wastage in the steam making processes of power generation, industrial and commercial boiler uses and especially trans-oceanic shipping.
(I'll leave jet planes & the milly-tarry out of this as those mentions would likely start a flame-fest...)
Folks think their 'energy' usage at home & in their cars is a big deal, so they freak out with the propaganda over car engine warm-ups, but in truth all the small usages do not add up to a drop in the bucket compared to just a smallish hospital that goes through 10,000 - 20,000 gallons of bunker 6 oil PER WEEK, and $50,000 - $100,000 in electricity besides.
And yes - I do know of such things as one who worked for many years as a licensed power plant engineer in industry, commerce and at hospitals as I gained in qualifications & moved up that career ladder.
A suggestion:
If your local DHS unit has not intervened, contact your biggest local electric utility & request to be included in their next power station tour.
See how many gigantic, ancient boilers are sitting there with their house-sized burners blasting, making ~1000 PSI superheated steam vs. how many turbines are being powered in the daytime.
Also - make a point to ask what is done to DISPOSE of the over 500 PSI waste steam after its one trip through the turbine.
Generally the answers look as follows:
3 boilers running - 2 'idling' hot & ready for peak hours 2-3 times daily, one turbine spinning using the 1200+ PSI steam from the one online boiler - and if the local wildlife is very fortunate, the plant is not boiling a local body of water to dispose of that pesky excess steam.
Big cities used to be powered by such excess steam - but most have stopped it, and why ??
The billing of users was too problematic - even though the needed infrastructure remained whole and it was a great way to heat large buildings in a city with a waste product.
TMI yet ?? Most likely. No apology offered, or forthcoming.
Last irritating mention for this reply:
Most folks also have no idea where their municipally supplied drinking water comes from, what is in it, or added to it - nor that the supplier must publish a yearly quality report for anyone to see.
If folks knew or cared to know - the sales of reverse osmosis water systems would go through the roof !!!
