Agree. I'd stick with 5 unless you get it tested and find there's life left in it.

The analyst at Blackstone told me I might be able to go to 5500 or 6000, but I stuck with 5. I do a lot of short trips. Some guys have tested and gone up to 7k and beyond, because their driving habits permit it.

YMMV.
