Lee, You have posted the same thing twelve times. They all show up as 10:35 PM Sat. here in AZ. Any chance you think the posts aren't hitting cuz your clock is broken? GW

I apologize to the group for the repeat messages. D*mn computer must have had an orgasm.
His news server screwed up.
How did you manage that ? ;-)))))))
Huw
Yeah, I am not sure what happened. I apologize for the flood.
Sincerely, Lee Richardson
That's what I don't get about the idea of sophisticated sensors detecting when the oil needs changing. If it was that, wouldn't that same sensor be better designed if it also turns off after it 'detects' that the oil is better again?
I'd think it would be more along the lines of specific things the computer already keeps track of. (Like the things previously mentioned... eng. temp, speed, mileage, etc). Especially if you have to 'tell' the computer that you changed the oil to get it to turn off the light.
It seems like it would be a trivial matter to put some kind of switch on the drain plug or oil filter base that would trip when the plug or filter was removed, and that signal could be used to reset the system.
Something was going on with my computer or IP, the problem seems to be cleared up now.
Thanks, Lee Richardson
But that adds complexity and wiring, the "sensorless" systems are basically free (just a bit of firmware) except for the light itself.
Best regards, Spehro Pefhany
True, but they don't seem to shy away from complexity and extra wiring in many other potentially less important systems.
Tend to disagree with your oil change mileages. Combustion is the #1 progenitor of oil degradation (and I don't mean oxidation) and not exposure to air per se. Heat resistance is part of the API & MilSpec tests for oil validation (if you need a standards reference). The #2 cause is the accumulation of combustion by-products washed during the lubrication process that eventually degrades oil detergents and oil quality (i.e. the detergents suspend dirt in solution). Hence the reason to change one's oil. Oils do not "wear out" by oxidation and can be easily recycled >>

It's not the oil that wears out, it's the supplement package. You need to replace the oil to get new additives. I would say in normal commute driving (short trips) the number one reason to change your oil is moisture, since it builds up condensation and never really get's it all out before you shut it off again. That's why your exhaust will rust off so soon.
