Right. But FE's are a bit more notorious for leaks because of certain aspects of the design. It's not just poor worksmanship.
Right now, I'm fine with conventional oils, and I haven't tried
synthetic, but it does sometimes cause leaks that weren't seen with conventional oils. Given my usage, I think I'll leave well enough alone.
