Adding Zinc to Oil?

[Steve Cassani]

Steve,

I'm reticent to follow the reps advice. I don't believe he's mistaken the capability of the oil to lubricate for many miles longer than other brands. The problem is that most of us accumulate 15-20,000 miles over three to four years, with six months of storage each year. Contaminents that would otherwise remain suspended settle to the pan and anywhere else oil accumulates. Moisture condensation becomes an issue for stored cars. I am not confident the rep has taken these factors into account.

Moisture compromises the ability of an oil to work as it should, especially in the first minutes after starting a car that has been stored for several months.
