I run plain old 87 octane. Nothing different since it was new.

I've owned several Toyotas now, most since they were new, off the lot and typically I didn't see real increases in performance or efficiency until around 25K.

Again, I'm not complaining about the fuel economy, just trying to figure out why.

Something I posted elsewhere:

Still, there has to be something in the management systems that causes this sudden wake up in mileage. Beyond the normal "it gets better mileage after break in" rhetoric as it has been my experience with a handful of new cars that 10% or more is not usual once the engine has seen a few miles. Additionally, I've noticed on all of the Toyotas I've owned that "break in" is usually somewhere around 25K... Short of AI there must be something in the software that optimizes the system. I think I'll make a couple of phone calls.


I have a couple of calls in at Toyota. Dunno if they'll call me back or not but it can't hurt to try the source.
