oil is still cheaper than metal , and really whats the big deal with a few extra oil changes o n a few pearsonal vehilces. and yes our clean burn brand used oil funace wil opererate on synthetic used iol , now any new motor oil will nit burn for one second until it is used enought to have some amount of carbon in it , all other new oils will burn new hyd oil , trans. oil, diesel will burn just fine brand new

My trusty A-C forklift with a Buda diesel 4BD-153 engine in her, keeps on running. Excessive 'blowby',low compression(needs 3 squrits of ether) she runs like a top... I've had every kind of 'oil' in her, SAE30, 10W30, 15W40,real,synth,semisynth,used,abused...whatever I have here, just 'topup' when oil pressure gets below 20# Added a few 'additives' like STP, BARDOL, etc., it's had 2 ,maybe 3 oil changes in 17 years. Last one, last summer,after I figured HOW to build ramps and platform to make it safe to get TO the oil plug... reminds me ,need to add some oil soon...below 20 today(oil pressure NOT temperature !) Odds are real good it'll outlive me.......

Way back in the early 60's had a car come into station for service as said he had knock in engine - was a 52 Chev 6 cylinder .
Asked when he last changed oil - Answer was he doesn't just adds when needed .
Well we rebuilt the engine - bottom of pan was sludge right up to oil pump intake screen and when valve cover was removed about a 2 quart capacity of oil drained out as sludge there prevented much return back to pan - he burned more oil through valve guides as they were flooded constantly with that oil reserve held in valve cover .
Engine had a bypass filter - which needed to be pried out of container as that was also solid sludge .

I am one of the old pfarts that used to wear out the drain plug. But now at 77 plus and counting, I think I try to not get "set in my ways". I change the Toyo at 10K.
Yeah and I do not check the oil every day cus times have changed and I do not hear the Pistons swapping cylinders" 
I was once visiting my daughter on the east coast. She had relegated the driving and upkeep of the old Rav 4 to the oldest grandson.
I yanked the dipstick and low and behold there was no oil showing at 14 K since the last change and the grandy "said" he did not notice the service light was on. However that noble beast was stilt getting him down the rod and everything was great.
So can these modern motors run with or without oil?
There was utube, back in the days of Obama's klunker program where a fellow drained the oil out of a Green tractor and let it run...and run, and run, and run.....and run |

Had a 70 Monte Carlo once. The 350 in it had a thirst for oil. Was using recycled oil that you could get at the convenience store then cuz it was so cheap. Cruising on the 2 lane one day heard the lifters rattle. Wasn't 20 seconds and she locked up

Had a 54 Chevy Bel-Air once that was going to the bone yard, so we drained the oil and put it in a field and put a brick on the gas pedal. Ran for a good ten minutes and then it ran out of gas. Drove it to the junk yard about 4 miles away. Ran when parked.

Can relate Ted, in HS a friend had his Grandma's 48 Plymouth four dour sedan, HATED the car, flathead six three on column no radio and just ugly but was free. So it developed a light knock as could hear it three blocks away and WE as mindless wannabe mekaniks pulled the oil pan to see what was bad. Number 3 rod bearing was melted hanging out of the rod where it had gotten so hot as it seems it used oil and he forgot to check it one Week, Got low(nearly Out) and started this knock. So pan sitting in floor we got the brilliant idea to see how long would run, drove it all around town hammering like a hundred blacksmiths in sequence beating on railroad iron, had no idea what would have done had it seized but it didn't, ran it home and parked it, next day was locked up tight and his Dad had it hauled off.

I had an uncle that used to change the oil once in a blue moon in his Pontiac Bonneville but never changed the filter. I said to him one day, hey Unk, why change the oil if you don't change the most important part-the filter? He said, ahhh that's just a waste of money. I believe he had just over 51K miles on it when it seized. Blamed it on Pontiac for building a crappy car! LMAO!
Engine oil does break down as Lou mentioned, and it also gets dirty from different driving conditions as Steve mentioned, that's why I change my oil and filters frequently in my vehicles. Like Steve, I've been doin' that for 50 years myself.
Coke had me laughing reading his post about the sludge. Dad had a 63' Chevy P/U he bought new in 63'. Fast forward about 5-6 years. I came home from school one day and thought I would change the oil in Dad's truck cause' I knew he didn't change the oil much in it. Before I did anything, I pulled the dipstick out of it just to see if it had any oil in it to begin with. The stick read full! Black, but full. Wow, its got oil in it! So I proceeded to get his drain pan that he didn't use, knock the plug out of the oil pan, and nothin' came out! WTH? Went back up, pulled the dipstick-Full. Borrowed a coat hanger from Mom, stuck it up in the hole, and the oil started plopping out. Needless to say, I dropped the 100 lb. oil pan, (that I wasn't ready for laying on my back) and the same amount of sludge like Coke found in his customers oil pan. right up to the oil pump! Dad was pissed that I had dropped the pan till he saw all the black mud in the pan. After I got the oil pan on a diet, (it was much easier installing it) Dad swore that old 235 inline six in that truck ran faster down the road. LOL!! Steve@B&B

Oil may not wear out, but the additives added at the refinery can, and do, wear out. It is one of the main reasons manufacturers recommend changing oil (otherwise we could just change oil and refill).
This is from the link below: "Most lubricating oils are formulated with chemical additives that enhance the beneficial properties of the base oil or make up for oil deficiencies. For passenger car motor oils, base oil makes up 70 to 80 percent of the final product; additives comprise the other 20 to 30 percent."
