I'm sure you're right, the stuff is worthless if not bad. The package says very little--they seem to have toned down statements about engine wear and gas mileage, at least this brand. But the business about oil dripping down and stress at cranking makes sense to me and perhaps this will help just a little with that.

Maybe my situation of having some nice cars that sit most of the time while I drive a Jeep Wrangler is unusual. Means superceding logic. I know it is terrible for cars to sit like that. But old cars with low mileage? It is almost inevitable.
