Nope, you are just fine, in fact better than fine I guess. According the the manuel, 70 is high. Things will depend on viscosity of your oil, maybe even the oil filter, etc.
As long as you are not low you should be fine, as you probably already know, the oil under pressures suspends the part in the oil, so that no metal to metal contact is ever made.
Just out of curiousity, are you running synthetic??
I run Rotella synthetic 15-30 (I bdlieve that is the weight) and a huge wix two (2) quart oil filter in mine.
