I've run 7,500k miles on the synthetic oils, even 10K miles on M1 HM in my Jag and all is good. I'm now liking the QS Defy in both of our current cars for the quiet, smooth operation and the SL rating it has that corresponds to the manufacturer's recommendations. This is not to say that I won't go back to synthetics and the longer OCIs.
It's all about knowing what's in your sump and keeping your OCI adjusted to it.
IMO, keep your options open. You may want a longer interval in your future.
Very open minded, logical, rational post.
