These service writers NEVER cease to amaze me with their "new lines"
. This ester oil has NOTHING to do with the engine oil temp. As per Nissan, the valvetrain noise is reduced when this oil is used. Though, a good synthetic oil will always have Superior high temperature stability and may even let you run a little cooler. But Nissan's "magic oil" isn't even synthetic. If I recall correctly, it's regular oil with ESTER additives
