No, Jim, I attach references so you know the answer didn't come out of
thin air. People can read the words themselves and make up their own
minds.

Some of the manufacturer's intervals are for marketing purposes only.
For example, dino Dexron III has a rated severe service life of about
30-35K miles. So why is it OK to change it at 60K miles in some of
Toyota's (Lexus) transmissions if you're under severe service
category? BTW, the low-tech Type-IV ATF is dino, too.

But you're right. For short term car leases I guess no changes are
needed.
