I know that it is possible to use Daytime Running Lights by leaving the lights on and the opening of the driver door at shut down turns them off. My other Toyota does the same thing. It seems to me that all the battery power use in the vehical is from the same battery source (unless I'm mistaken). According to what I have been reading, battery drains will decrease mpg's, therefore, doesn't it make sence that using daytime running lights may decrease mpg's?
I've thought about that. Figured it wouldn't be as bas as, say, running the A/C all the time. I put it in par with a sound system always on. That's a great avatar.
What I was thinking is that if I'm already running A/C (I have to often living near Palm Springs), running the stereo, and the running lights, it all begins to add up.
I drive with my headlights and running lights on plus the air... am happy with the 48-51 mpg that I've been getting per tank... beats the 15 mpg in the Dodge.. and although fun to drive 22 mpg that I get in the '51.. as we are looking at snow over the weekend... the '51 with no heater is put away...
