I chose 5K OCI because of the round numbers, and of course its still much better than the ridiculous 3K. Also, I think the V6 works a little hard to cruise at 75mph everyday, but maybe not.
I am not seeking to just be "cheap", but to find that optimal OCI point that balances protection and economy.
You're thinking along the right lines with the OCI.
Considering the high quality of dino oils theses days, it's not a stretch of the imagination to think you can go longer on the OCI TO 7.5k to move toward achieving that balance you're looking for.
However, you could actually optimize your situation by fitting a bypass filtration unit.
You may well be able to go 10- 15k on your OCI, and reduce wear to almost imperceptable levels.
Then take it another step forward and use a top quality synthetic oil.
When one factors in the minimal time spent on actually doing the oil changes, it's possible to be way ahead of your original starting point of 5k OCIs.
