Are the DRLs for that car half-intensity high beams, as on so many other cars?
According to sylvania.com your car uses 9005 high beams. Also according to sylvania.com 9005s use 65 watts each. At half-intensity, that would be 65 watts total energy usage. That's 0.0871664358 horsepower.
Can anyone finish the calculations and guess what effect that has on fuel economy?
not sure of the calculation but the increase is very small. I figure tenths at most of an MPG. I did mine about the time the weather started getting cold so I haven't seen any gains, only losses (all due to cold temps).
I did watch my engine load while doing mine. before the disable, I was running 24-25 (teetering between them) and also 28-29 with my lights on (like in the rain) after disabling them, it is hittin 23-24. there is a difference, just not much.
I look at it as not much but it was free to do and a few more "not much"s will equal out to a descent amount. that's rednek math there.
Be the change you wish to see in the world
