They flew a 29 out here for display and even a few sightseeing flights
over Memorial Day. There was a large pilot training base here in the
war. Silos on the farm were a landmark for return lineup for landing.
One fella' who flew them and was trainer here took a turn and retraced
his old path--discovered we'd had to take the silos down. I happened to
be out when he flew over at about 150 ft or so.
Not "a B-29" but the ONLY flying B-29. Also known as "Fifi" operated by
the Commerative Air Force out of Texas. There is one in Witchita at the
Boeing facility being restored to flying status, but it is still a few
years off. http://b-29.boeing.com/ So, out of the 4000 or so made,
only a dozen or so exist on display at museums around the country, one
is being restored to fly, and one flys. The rest were scrapped or used
for target practice by the Navy at China Lake.
A lot of the chips and dust are wood, but a lot isn't--the inevitable
dirt and other grime is at least as abrasive as the much smaller
diameter particles that made it through the engine oil filter...after
all, you wouldn't be particularly concerned to run your auto another 500
or even 1000 miles above the 3000 mi mark if you were on a trip and
needed that to get home for a more convenient oil change, would you?
The lube requirements of any modern engine are <far> more onerous...
By the same token, I don't think it at all obvious there would be much
difference observable one way or the other as opposed to clean motor
Seems to me like the "stale gas" thread or the "diluted 2-cycle gas in
4-cycle engine" threads of recent history... :(
I rented a chainsaw this weekend. Ran out of bar oil,
went to the rental shop. They filled the bar oil bottle
with 30w oil because they didn't have any bar oil left.
This was done by the lead supervisor on the job so it
must be ok.
Well, that's a stretch to conclude... :)
(Although I don't disagree w/ particular action, just to draw the
conclusion the action of a "supervisor" implies knowledge is a stretch
Although I will say it's the first rental place I've heard of that
wouldn't consider the lube oil a "consumable" for which the renter is
responsible, just like the fuel...
I've got a 25 yr. old Poulan that has an 18 yr. old bar. I've used the
hell out of that saw on_big_trees over the years. Only reason I changed the
bar was it got bent when a tree pinched it when I was cutting on a hillside.
I've always filled the bar oil tank with used motor oil. My chains last a
long time and it should be evident that it sure didn't do any damage to the
bar. I do pump the oiler quite a bit on the saw and keep the bar well
lubed. Now................................wait for it.
Some horse's ass will tell me I'm spreading carcinogens to the little forest
creatures who might come and lick the stump that has used motor oil on it.
Sound like your thinking parallels mine... :)
I'd never thought of it as a use for the old oil and since each of the
large tractors takes 16 qts/change, it adds up pretty quickly here on
the farm... :(
There's only so much that can be used on combine chains, etc. I'll
probably go to a used oil burner for some heat in the shop here in
another winter or so when I get the rest of the barn refurb far enough
along to have actually got it close to tight...at present no windows in
anything except the shop itself, etc., so far so not much purpose 'til
can get farther along and farming comes first this time of year.
You are spreading carcinogens to the little forest creatures who might come
and lick the stump that has used motor oil on it.
Not to mention getting cancer yourself by handling used oil.
being a horse's ass is better than being a DUMBASS
And if Bullshit was music, you'd be a brass band, tough guy. You're exposed
to several orders of magnitude more carcinogens by just breathing the
exhaust from the chainsaw. But I guess you go to the woods with a medical
compressor and respirator. Typical environmental whacko. Not enough sense
to pour piss out of a boot.
I know several wood cutters who use the used motor oil to lube the bar
and chain. They cut a helluva lot of wood year around and I've never
heard them complain about the oil hurting the saw or it's chain.
I don't advocate using used oil. But new oil is
dirty as soon as you drive 1 mile after an oil
change. If you are changing your engine oil
every 3 months/ 3000 miles in a good engine, there
is lots of lubrication left. Some car
manufactures seem to think there is at least
another 2 months/2000 miles of use, and some seem
to think there is another 4 months/4000 miles of
If it feels oily, it will lube the bar just fine.
We're not talking fine tolerances. Any opposing
argument is justs specious.
I'm wondering which part of "The first time the tip touches dirt even
for an instant, you've just put more crap on the bar than any amount of
used motor oil possibly could" you can't comprehend.
Face it, Doug, waste oil is perfectly fine as bar oil, despite your
bleating to the contrary.
(And the greenies who might want to cry about it are perfectly welcome
to go suck rocks.)
