Engine wear occurs during engine cold starting. Stop/start city driving can increase the amount of hard starting that occurs before an engine is up to temperature.
City traffic, traffic jams and short drives lead to higher stress on today's vehicles engines. When combined oil change intervals that are too long, this can lead to premature degradation of the oil system. Good lubrication is essential for the engine, but for some components such as the turbo, it is crucial! Poor lubrication of the turbo can result in the turbo jamming or being destroyed.
Wynn's oil treatments prevent the premature degradation of the oil system, by improving the lubricating and cleaning properties of all engine oils. They aid in the reduction of friction and prevent formation of black sludge and varnish on the engine components
