Never Change your Drive Lube and your Driver will last for EVER!!!!
 

Ok, long story here.....

Back in 1957 my dad read in the paper that Macy department store in NY city would never change the oil in there delivery trucks but would only change the filter and add a oil to top off the amount lost within the filter every 5k and they where getting over 250k on the truck engines. So my dad not a car guy buys a new 1959 Sports Fury and never changed the oil in it and sold the car when the trans went out at almost 200k. He also a had a small flleet of dry cleaning trucks that he did the same on and they lasted too, so Fast forward and I buy and sell shop equipment used in areospace and high tech companies, and what I learned was that they will not always change out a lot of the oils and chemicals used in machines and manufacturing processes and I believe it is called titration. So lets say the drive holds 3 qaurts and is changed at 30 hours for ****s and giggles, the oil in the drive at the first ten hours is 30% dirty, 20 hours 60% and at 30 hours it would be 90% dirty. So the first 15 hours the oil is twice good as the dirty oil the last 15 hours? We as boaters should change out our drive lube every 5 hours!!! All we do is drain enough oil out untill the fill bottle justs runs out, put the plug back in and and top off the lube bottle. So if we change out 1/2 a quart ever 5 hours we would be in better shape then running very used, broke down and dirty oil for the last ten hour to save money!!

let us know how that works...

I know this works as my dad proved it. Also a know of chemicals used to electropolish in tanks that hold 1,000 gallons, companies do not throw 1,000 gallons away after it gets dirty and stops working like it did when it was new, they will remove 100 gallons of old fluid and repalce with new fluid which keeps the fluid working at it's best. But they don't wait until the fluid is completely dirty to do it, but just after the fluid shows signs of getting dirty. But my point is, that the last 10 hours we are using dirty broke down oil which is much worst then the 10 hour fluid?? With additves being used up and oil that break down, put im fresh all the time should help, plus lets say water or a problem shows up in each mini change out it could help to know every 5 hours verses 30 to 50 hour???

Could work on a 4 cylinder with an Alpha. What power & drive do you have??

Ayuh,...... Good luck with that idea,.....


Outdrives don't have oil filters,....

'n the oil don't wear out, it gathers contaminants,...

I could be wrong but I believe the oil breaks down due to the shearing action of the gears.

The problem is that oil filters do not really clean the oil, they are there to prevent large pieces of metal destroying the engine, My point is that we leave the oil in the drive and the last half of the time it is in the drive, the oil become more saturated with metal, the most wear is in the last half of the oil's life, Additives break down as does the oil, by replacing them a small intervals the over all condition of the lube is at a higher level of condition then the normal way of running dirty oil the last half of it/s life. Also if the heavy metals are settling at the bottom of the drive between trips, if you remove a half quart of oil from the bottom, you just removed the worst oil from the drive and repace it with fresh oil that will work its way to the bottom. It should only take ten minutes to do this so seems easy enough.

Your example comparing hundreds of gallons of something to 2 quarts (Alpha) is not valid.

Big Diesel trucks can go so many miles between oil changes because of there oil capacity and the stresses and controlled environment they work in.

Do what you want to do. People win in Vegas all the time.

Are you doing this or just a theory??

bad idea - as oil heats up and cools down it forms condensation also where I live you can leave an outdrive with fresh gear oil - never used still brand new and check it a year later to find it has a tablespoon of water that formed internally because outside temps drastically changing forming condensation.

Also oil from heating up especially at very high temps plus the combustion process forms oxidation & acids and oxidation & acids can form corrosion another reason to change your oil and why all oils have corrosion inhibitors. Hot rod, classic car, motorcycle and marine oils mostly all have an extra dose of corrosion inhibitors added into the blend for a reason.

Also the combustion process itself forms water / condensation. That's proven as you can watch the water expel from the tail pipes of cars everyday especially right after taking off from a red light.

Most base stocks of the oil itself do not wear out, its the additives and the contamination factor that's the reason for changing the oil. Gear oils are a bit different as they can experience the shearing effects from the gears rotations & pressures.

Also changing your oils can be used for inspection to avoid bigger problems down the road. ie: dilution of - water, fuel, gelling, anti freeze, wear metals, burnt, along with coloring of the oil itself - black, metallic, white, brown, chocolate, mayo and so on.
