not in this case, the srt6 needs to take heat away from the pistons, because it has higher cylinder pressures.
And No, not with synthetic oils, they don't break down until you hit very high temps. way beyond the limits of this engine. not positive what mobil 1 states the limit is, but I'm sure it can handle 600 degrees F with out sludging or coking up.
also synthetic oils do not wear out! so heat can't hurt synthetic. it's not about extending oil life. that's managed by the additives and your oil filter. that's why a lot of you guys waste good synthetic oil at every oil change, where as you should get the oil analyzed before dumping it out of the crank case. most of the time all you need is a bypass oil filter and just add about 2 quarts of fresh stock to replenish the additives that have been used up.
