I use synthetics too, in the engine, transmission and differential. Your mechanic is probably seeing a lot of little oil leaks...GTX will minimize these. The synthetic oils will ooze more as they're thinner. I just ignore the leaks & run Mobil1 5w30.

Shell rotella synthetic 5w40. It's cheaper than some non synthetics.

15-50 is that a joke?

That's what we run in the race car. Not sure it's really necessary for street cars, but do what you like.
