The simplest way to explain it is: Think of the W rating in oil as "winter". How the oil flows at zero, or sub-zero temperatures. As the oil is tested it's assigned a "value" by the petoleum product manufacturer's association. Generally the lower the first W value, the faster it flows in cold temp.s But realistically zero weight oil, is an EXTREMELY light grade of oil, and won't survive long in use. It's properties degrade quickly, --- cruznmd <racuti1@xxxxxxxxxxxx> wrote: > > > > The oil debate has raged here for a long time. You > can see it in the > archives.
