Synthetic blend oil
Don't worry, this is not another which is the best oil thread. I did a search, but didn't find exactly what I wanted.
I just have a simple question. Is it true high mileage engines may have a greater chance of encountering problems with full synthetic oil? I'm currently running Castrol 10W30 Synthetic blend. The engine runs fine with it, so I don't know if I should stick with it or move on to full synthetic.

It isn't guaranteed there'll be leaks, but it is more likely due to the smaller molecules in synthetic oil. If your motor has been well maintained, I wouldn't worry too much about it.
