Default Re: Does anyone else here feel like we lucked out?

Gripper Don,

Did I read that right - you have 200 miles on the car? If so I'm pretty sure I know what your "problem" is.

When Toyota designed the HSD system, low emissions (hydrocarbons and CO, NOT CO2) was the first rule programmed. Good fuel economy is a second and lower priority.

In order to achieve the low emissions, the Toyota system burns a lot of "unnecessary" fuel to get the catalytic converter up to temperature. This can take 5-10 minutes depending on the ambient temperature. After the converter is hot the car then goes into it's "economy" mode.

This means that short trips are a KILLER to your fuel economy.

My Camry has the nav system so I have the MPG graph that shows my MPG average for the last minute for the last 30 minutes since I started the car.

When the car is cold I get sucko mileage for the first few minutes. After that it steadily climbs. On long trips I can easily average 40+ MPG. On short weekend errand trips I might get only 30 MPG.
