Oils aint oils

You know, I've often wondered what owners of really extensive car collections, that all sit in climate controlled garages, do. My car sits in a climate controlled garage, and I now put a few hundred miles on it a year -- less than a thousand. Every year I send a sample off to the lab and they check for the usual wear elements, zinc & phos, and the like, plus they look for moisture, antifreeze, fuel and a TBN as well which you can compare to the TBN of your pure oil. But I don't just change it to change it -- there's just no reason to.

One reason is peace of mind. If you change oil way before time, you will not hurt motor.Not sure what you pay for your test,

but I can save that money and know I am good . {Just Saying} as my kids would say

Wouldn't you obtain more peace of mind by knowing whether you had a significant pattern of wear, or by getting early notice of that small bit of antifreeze that is tipping you off to a gasket leak? Or just knowing how well your oil is holding up? Why would you just blindly change your oil and flush that valuable information away?

First let me say in spec does not mean fully protected oil. Another is contaminants will be removed. You also should check your radiator fluid for leaks and contaminants at least every oil change.fresh oil will help ring seal and car will seem to run better. yes partly your imagination but some truth too. Not saying your way is wrong just saying my way is better.{peace of mind}

Alright. If that provides you with peace of mind, then I won't argue it.

The article says that for every pound of fuel, the engine produces a pound of water. But that water is not going into the sump but out the exhaust. I have run some of my cars on LPG and the oil stays or looks a lot cleaner. Also since fuel injection engine shut of the fuel the instant you switch of the engine, there isn't any fuel draining into the sump. Where as a carby, as the engine runs down as you switch of the ignition, it will continue to suck in more fuel and it doesn't get burned. JD
