Well you seem to decipher some of it just fine. The age of the oil isn't going to prevent a leak if that is what your thinking was said. The point was the age of the oil can make a difference in some situations. A fairly small amount of glycol added to dirty oil can do damage where that same amount added to engine with fresh oil can avoid the damage. One of the consequences of adding the small amount of antifreeze is that it will rob from the dispersants and detergents their power to hold fine particles in suspension. That won't matter as much if the oil is not very saturated with fine particles. The point is it is inaccurate to say there is zero risk to storing the fine particles suspended in the oil. You can if you want debate how small the risk is. -jim

Try writing more clearly. I don't care to wade repeatedly through lousy writing; I have to do enough of that at work. -- Tegger

I'm one of those guys who believes in 3000 mile intervals because it has always worked for me. Do I care if no one agrees with me, NO. Do I care if I can extend it to 5000 or more miles, NO. Do I claim my way is the only correct way, NO. In other words, you do what works for you and I'll do the same.

Are you saying no? yes, i'm saying no. it's illogical nonsense. -- nomina rutrum rutrum
