I used to torque the filler to full specs never had a problem just felt it was a little to much. I also change mine at least every other oil change. Not because it needs it but because its takes to long to go thry a quart of the oil and well definitely used to do it everytime 4went to grease the rear drive shaft splines. I do not do that as much anymore because I've noticed the particular Molykote I use stays in place and doesnt seem to dry out. So I figure a longer time span test is needed.
