Cruising at 180 to 190, and spirited driving pushing it up to 220 or so, would be ideal I would think. What do you think daily cruising temps of 220/225 (for those of us with no cooler), and occasional spirited driving increases to 250/260, will do to the longevity of the engine? There is a line of thought here that these temps will shorten the engine life. Is there any definitive reasoning that this is the case? I guess the best way to be safe is to add the cooler.
