M Another oil question

BILL

Back when these tractors were built and sold, there was no such thing as "hydraulic" oil. We had 10, 20, 30, 80/90 gear lube and bought grease in 5-gallon buckets.

10 weight was considered the norm for winter use and 20 or 30 for summer in both engines and hydraulic applications.

Then, the marketing boys came along and saw that they could make another buck by developing all these "special" oils and lubes.

I still only buy two oils. A drum of the lighter hydraulic oil and a drum of engine oil and use both in everything from the lawn mower to the hoists on my truck.

The iron doesn't care or complain. It is inert and has absolutely no preference. :>)

The military used 10wt oil for hydraulic oil for years. The M88 and the M578 all had hydraulic winches and booms and they both used 10wt oil. Since I've been away from it for almost 20 years I imagine that has changed. Hal

I've told this story before, but like to repeat it just to prove my point.

Knew this fellow one time who was going fishing up in the wilds of Plentywood, MT. Clear the heck and gone out from nowhere. Drove a little overhead cam outfit. A Ford Escort or some darned thing.

Anyway, this guy is 90 miles from home out in the boonies and hits a rock which put a small hole in his oil pan. There he is, the middle of the night and he's stuck facing a 90 mile walk. (Before the days of cell phones).

Anyway, he plugged up the hole in the pan with a common rag. Filled the crankcase with water out of the fishin' hole and drove on home.

Next morning, I helped him yank and repair the engine pan, put in a fresh filter/oilpopped 'er off and the little car was still runnin' about the countryside the last I knew. :>)

Iron doesn't care. It just needs some sort of a liquid lubricating agent to keep those movin' metal parts separated from one another. :>)

First we got Merlin tellin' us not to change our oil, ever. Now we've got Allan tellin' us not to USE oil in the first place?!!?!?!?
