"im never changing my oil" thread discussion
that guy didnt make any sence to me i saw what he was doing and his punch line was "never change your oil and save the earth maybie your childrens limbs or life" now how does oil happen to take ones limbs or life? and to tell yo uthe truth the earth aint goin nowhere folks WE are. from the ground it came to the ground it will go back. and to tell yo uthe truth either way sometime something is going to clog and cause your engine to use oil and when that happens your destroying the earth even more rapidly because now your burning oil too. smart move.

Whoa.
I don't think he (or should I say she ) quite said it like that, but he's gone anyway. Moved on to other diesel forums...as this topic should have.

Please let the misguided "never change your oil" idea die.

Most farmers wouldn't dream of not changing fluids on the diesel machinery they have. Then again, when a used John Deere with air conditioning costs $35,000 easy, you tend to take care of it.

Break the dependence on oil, save the need for securing those interests, keep the kids from being killed and maimed. Not changing your motor oil is about the most counterproductive way to do that though since it only works if you don't replace the car when it dies. However, that said, there was a recent article where Ford was considering extending their oil change interval to somthing like 12,000 miles for new vehicles designs using new oil formulations. And industry people were quoted as saying the intervals could be extended far further than that given the way most people drive and that sensors were available to tell people when the oil actually needed to be changed well in advance of when any damage would result.

I am not in agreement with the theory of old Joe either but, I will say this.
I recently found out that some long haul trucking companies are using the "never change you oil theory" in thei big rigs. They are running high grade synthetic, changing the filters and just toping off when needed. For what its worth.

this was stated on another thread, but i think this is the key to that reasoning..
if your car eats up a lot of oil, then this could just very well "hold water", but if you have a healthy engine that doesnt consume oil, i think you'd still be better off with a regular change oil.

Yes, there is a middle ground, as we are seeing.
the 10,000 mile oil change interval was just a standard because it was a safe interval where you were assured that no matter what happened, your engine would be safe from damage. Fairly sure, anyway. The oil probably doesn't need changed at 10,000 miles the majority of the time, but it's not the ones that don't need changed to worry about, it's the ones that do need changed and would ruin their engines if the interval was larger that matter in this case. I do believe in the above, but i continue to change my oil at that interval even if it doesn't need it. Why? Mostly because I don't want to find out when it does need changed. No one wants to risk engine damage. No one sane, anyway. As sensors for this sort of thing come out, the interval will get longer because you can change your oil when it is needed, not just when you guesstimate that it might need it. We don't have that luxury, so keep changing it out.

Let me clarify what I said before some someones head inplodes and a 240joe-type agument breaks out. Some long hual companies are not changing there oil like they use to. The typical 20-25k oil change that is, SOME are going a lot longer-close to 200k before changing the oil-they are using filters and bypass systems but calling them oil purificaiton systems (whatever that means) they are still leaving the oil in that long-topping off of course. I am not a long hual trucking expert but I have some very close relatives that work in the industry. I realize not all trucking companies are doing this and its likely that only a few are but it is happening.

Here we go again.....
On the ships, the company that I worked for (and I understand that most ship operators are have similar policies), we only changed oil if we had a "bad" oil analysis come back......please bear in mind that most of the big main propulsion engines are constructed (internally) differently from "automotive" type engines......most of those big engines are of a "crosshead" type.....this means, (briefly) that the connecting rod is connected to the "piston foot" at a device called a "crosshead".....sort of a 2 piece connecting rod.....this means that there is a stuffing box between the underside of the piston and the crankcase proper, that prevents any by-products of combustion that get past the rings from getting into the crankcase oil......it is held in a "buffer space" that also collects excess cylinder oil and other gunk, and is drained off a few times daily....as needed.....
The auxiliary engines (generators and such) are more like locomotive engines, and are constructed a bit more like "automotive" engines......we had a simple field test for viscosity, and topped up the sump to maintain level and viscosity....... We also had purifiers, centrifuges, big centrifuges, and would run those on all engines on a rotating basis.....as the theory goes....trickling a little water into the centrifuge (it is separated out while centrifuging), removes "some" of the acids and such that find their way into the lube....but the centrifuges remove soot, and other particulate matter, big time...... When you have better than 12 to 15 metric tonnes of lube oil circulating, and oil change can get expensive real fast......1 metric tonne is 1000 liters.....so 12,000 to 15,000 liters......at about $1.00 - $2.00 per liter......
