That guy is making it too complicated. Easier way is to take pliers with a nail. Get the nail glowing hot with a torch and then stick it in the oil. Clean oil will do nothing. Water in oil will sizzle.

what happens if you have gasoline in your oil? do you go boom?

I think the guy needs to bone up on his physics. He claims that water will change state at something less than 212F. Also how does he know that his oil sample has about 10% water as he claims? I dont understand his statment that he now has to find a way to dispose of 55 gallons of used oil as it is contaminated. If it were not contaminated would he not have to find a way to dispose of it?

JMO but doesn't most used oil end up with some water in it from condensation, especially with short distance driving. One of the reasons short distance driving is so hard on the engine is oil doesn't get up to full temp long enough to evap the water out.

bingo and the light flickers on...short cycle driving does lead to oil contamination of air born mositure as it condenses..and yes only a sustained period of operation at temp will effectively remove this moisture....

while looking to see what if any percentage is define as existing water in oil of any given engine with used oil at given climate/temperant zone..I found nothing..but his was good reading..

The best thing for your engine would be that it was never turned off, you simply kept driving day and night. The oil thickness would be uniform, it would always be 10. In a perfect world the oil thickness would be 10 at all times and all temperatures.

at least it appears somebody here has read the link...! it was interesting to say the least...

Actually the branch of science is CHEMISTRY. Yes water will change state at less then 212F/100C. Water has VAPOR PRESSURE if it did not it would always be wet after a rainstorm.

can we talk about building a house, maybe I won't feel so left out and very uneducated.

Sure, Todd. What would you like to know?
