I was just curious about the switch to synthetic motor oil. Is it ever to late to switch to synthetic? Like having to many miles? If so, how many miles is to many miles?

It's never too late or too early to switch to synthetic. You can use it anytime.

So go ahead and do it now!

There is one stipulation to this. If your engine has been neglected to the point where sludge has formed inside around some of the seals, you can and most likely will see oil leaks develop. If your engine is well taken care of, then you will experience no problems what so ever.
