say a guy buys a new olds 88, uses 30 wt.oil (single grade), never has a
motor problem, how do you account for that?
He's not living in Maine, that's how I account for it. If he's living in
Florida, that's fine.
is this "additive" package so much hog wash(?) and is only used as a
replacement for the good oil it replaces.
Well, if he buys 30W oil, it's still chock full of additives, including
lots of detergents to keep combustion byproducts in suspension. It just
doesn't have any viscosity improvers, that's all.
If the operating temperature is always constant, viscosity improvers aren't
needed. If the operating temperature varies a lot, they are essential.
25% of a quart is 8 ounces(additive), that is supposedly a curative for
the oil's "breakdown". that's asking a lot.
Well, you could argue that 100% of oil is actually additives. Including
the oil part.
