PP 5W20, 2500 miles on the fill. Ford 4.6 3v.
The oil has been in there for six months now and just last weekend I went down the drag strip about 10 times on it.
Worth changing?
Should I change it?

If it were just easy miles I would say leave it in, but 6 months/2500 and 10 drag strip runs... It's cheaper than a new engine to change...
Send it in for a UOA so you know for next time?!?
