Reply #65: I have an 05 Jetta TDI, and my mileage varies wildly, depending on [View All]

outside temp and duration of drive

low thirties when it's very cold.....less than 20 degrees, and less than 20 minutes in the car, which about what it takes to get to work. also get about 10 mpg better on the way home from work, no matter the temp. guess the engine doesn't cool off all the way after 8 hours

up to 50 when I've been on the road for over 45 minutes at about 60 mph

best thing about it is that running the AC, even in mountains of WVA, mileage isn't affected, where it seriously put a dent in my other cars' mileage

bad thing is the ridiculous diesel premium, around 40-50 cents/gallon more

have you noticed that sort of variation in your mileage?

oh....I bought a diesel with the idea of not having to buy another car for a LONG time. when I bought it, I wasn't so sure about hybrid battery life, and didn't think I could afford another car for a long time. I had an Accord for 15 years, so I hope the diesel gets me more than that. we'll see how well VWs hold up
