Most newer cars that use a true oil life system, GM's comes to mind, that base the life and change interval on many factors.
It's an active system that looks at avg speed, avg rpm, peak and low rpm times, engine temp, time to engine temp, some monitor oil temp, etc.
A GM oil life system can indicate an OCI as low as 2500 miles and as high as 15 to 20,000 miles. This all assumes that the operator/service facility uses the CORRECT oil for the car. One that meets the GM spec called for in the owner's manual. All bets are off if the incorrect oil is used.
I'm not sure if Honda's system is active or not. I'd like to believe it is, then that way the car will decide when the changes are due based on the way the car is operated. Using synthetic oil isn't necessary, at least as long as the 5w20 oil that's used meets the requirements set out by Honda.
There's where it gets tricky, as Honda doesn't publish an actual "spec" like GM, Ford, Chrysler and all Euros do. The only exception is the RDX's spec of HTO-06 for the turbo 2.3.
You can't believe what's printed on oil bottles as most don't meet the specs they say they "exceed".
Only Mobil 1's labeling is accurate that I know of.
Remember API specs are made by the oil companies FOR the oil companies. Car manufacturers have no say in that. Even the ILSAC GF ratings are more an oil company reaction to a wish by the car companies need for lower friction, catalyst friendly oil.
