My mileage has been going up.
Dunno why, but I've gotten 49 mpg in my daily commuting in my 2004 Jetta TDI wagon (5 speed manual) for the last 2 tanks, when it used to be around 44. Perhaps the engine is continuing to loosen up - it has around 85000 miles now. The EPA rating was much lower - I dunno how any revisions to the EPA rating scheme compare now.
The last time I filled up, diesel at Hess was $4.09 while regular is around $4.18. Diesel prices vary quite a bit during the year - sometimes cheaper than regular, sometimes more expensive than premium. I'm still happy with my choice, but it's not an appliance like a Toyota. Cheers, Scott. |

Tyre pressures?
Makes a difference.

Maybe. Seems like a big change though.

does it tend to go up in the winter?

Diesel, the petroleum product that powers most buses, trucks, and other large vehicles in the US, is nearly identical to heating oil. Both are classified as distillate fuels, and the two main differences are that diesel generally has a lower sulfur content (making it more efficient and cleaner-burning) and is a clear liquid, while heating oil is dyed red for tax purposes. |

Yes, but it varies.

Too many things other than the season and the usual cracking mixture determine diesel prices these days. If things ever settle down, it'll be more seasonally predictable again. Cheers, Scott. |

Summer/Winter blends
The Winter blends have more "thinners" in them with takes some potential energy out of the fuel.
Summer #2 Low Sulfur... is very potent stuff. |

Could be. Thanks.

That, or you're going downhill more often...

Both ways!
