hehe !
Many years ago.... after using a steam/pressure washer at work and being amazed at its power to clean the grime off the Forklifts I had to work on, I decided to see if I could make my own
...I took a coil of copper tubing and hooked it to a water hose through a nozzle I modified for the task... but lacking a burner of enough heat capacity (a camp stove don't make it!)
I used the bar-b-q.... sense the garden hose was connected directly to one end of the coil, I just pushed on a vinal tube for a hose on the other end...
there I was standing with my back to the bar-b-q squirting down a bicycle with the hose and man it was working good, and you guessed it the vinal hose popped off and shot me in the butt with scalding Hot water and steam..... needless to say I moved rather fast without having to even think about it.... my feet said run.... and I was along for the ride ! HAHAHA!
that experiment was over... so I decided to bar-b-q some hamburgers instead !...
I didn't get burned but it wern't fer trying ! LOL
and sense then I've been going to make me a steam cleaner...one with a Propaine burner and proper high temp outlet hose.... just havn't got around to it yet !.... but I have to admit it would be nice to have to clean off the tractor or any of the stuff around here...Humm.

Abe .. I made a Oil Reclamer back in the 1980's from plans in MEN.... it was a PVC pipe tube arangement that had a light bulb under it for heat... and a needle valve to restrict the flow out.... and about 4 rolls of torlet paper down the pvc pipe....
... at the time I used allot of bulk oil in 2 gal tin cans, and after filtering it through that filter it was as good as the oil I was buying... at least ! it filtered out ALL the black
and made it see through to a certain extent once again... I used that oil in my ford Pinto for about 3 years... same oil, just added a quart now and then to keep the level up....
by the end of that time the oil was getting fairly thick and even changing the filter paper didn't fix it.... so I went looking for oil for the car... I looked at 30wt Pennzoil and it looked like water it was so thin.... looked at Valvoline and it was better, but still fairly thin.... bulk oil was becoming very thick at that time and even though it said 30wt I'm sure it was closer to 80wt!...... so I bought 40 wt Valvoline and I gave the oil filter to a friend of mine when I moved....been using 40wt Valvoline every sense... because I got talking to the guy stocking the shelves on the oil racks and come to find out he was purity much an expert on oil.... he used 30wt Valvoline, and I asked about the thinness of the oil and he said well the engine needs thin oil to lubricate all those small parts... and I laughed , I said you must have a newer car Uh ? he said well yah , why do you ask? I said because my cars have 300thousand miles PLUS on them and I need thicker oil just to keep them from flying apart ! and he laughed and said well yah...maybe you should try this and he handed me a bottle of 90wt gear oil ! .... I said laugh if you want but I've been running thicker oil than 30 wt for years and my engines are still running... before I started doing that the best I could get was 150,000 miles... and the engine was totally toast!
he said well sure, you should change the grade of oil as the gar gets broke in, and then at 100K miles and then at every 50k above that... he said that's why most reputable Autoparts stores carry oil up to 60wt ....
well, I let that sink in and thought about it for a few months and in my 300k miles car that would put me at 50~60wt...(the only oil I can find with those qualities is Valvoline 50~60wt Racing oil...at near $3.00 a quart....and I dislike multi-grade OIL immensely !)
back in those days changing oil was a science... not a just put in 4 quarts of 5~30wt Quaker state oil, and call it done.
So I am guessing that the LIFE SPAN of an engine is some time after the 300,000 mile mark
but my experience with Diesels puts that statement down fast where 500,000miles is about average, and a Million miles between overhauls on big rigs are not that unheard of....
so what oil do they run

... well it ain't 30wt at last check <GRIN>
my Step Dad had can after Can of 40wt oil around here for years, and he drove for Puritan Bennett, hauling Nitrous Oxide all over the U.S.A. he put well over 1 million miles Just with them... so I got the idea of using 40wt in everything !...even the lawn mowers ! and Motorcycles ! .... so far so good... been doing that for the last 20 years now ! LOL and I ain't had a sized engine yet...
LOL
...I say sure break in the car using the recomended oil, don't void the warentee...but soon as its out of warentee and broke in switch to 40wt......I did that with our 85'Toyota Tercell
and I parked it when the rods started knocking on startup... at 350,000miles.
I think that's puirty good for a toyota !
now we have 2 other cars , both toyotas, a Cilica and my Pickup...both have 300k miles on them.
Both are running 40wt... and I have been trying to get the 50~60wt racing oil for the cilica
sense it has the most miles on it...but I wound up with another case of plane o'l 40wt... so I use that !
LOL
....
hehehe sorry guys , just rambling on again...didn't mean to write a book here ! LOL
