Taco Highway Gas Mileage - Tailgate up/Tailgate down

Just move to California (or Nevada) and it'll suck all year. Seriously.

16.5 to 17.5 typical.... maybe 19 or so on the highway.

If I buy gas in Utah I get 22 on the way home.

Other factors in poor winter mileage is that the AC compressor is running when the defogger/defroster is running... plus perhaps extended warm-up intervals.

That's probably because the CA reformulated gas has MTBE or Ethanol added as an oxygenate that drops the BTU per gallon, lowering fuel mileage about 10%. Utah gas is just straight gas.

Negligible mileage effects, though it does use a bit of energy the defrosters work /so/ much better with the AC cycled to dry the air when it's really damp.

Which is the big culprit and something people have to be taught not to do, as it's actually bad on the engine - extended running with no load at high idle is a good way to get raw (still liquid) fuel past the rings and dilute the crankcase oil, causing extra wear.

You only need to let it warm up 15 to 30 seconds (long enough to get the oil circulating everywhere) while you wipe clean a viewing hole through the fogged up windshield - then start out driving slow and easy, let the engine warm up faster with a light load. When the temperature gauge starts rising and the defrosters kick in so you can see, that's the sign it's okay to speed up to normal.
