The primary reason is the excessive friction that happens in the engine and the transmission, which is never good news for the mpgs. Some drivers notice a dip in fuel efficiency because they leave their vehicles running idle outside to warm it up before driving it.
Do you need a reliable vehicle to get you through the harsh winter weather coming up? Furthermore, for the many trucks that are equipped with high-efficiency tires, you now get less benefit from them at high speeds. Not to mention the fact that driving at higher speeds wears the tires out faster and costs even more money over time.
And the net result? The longer the trip, the more each factor represents. It should be clear that driving habits and driving speed have the biggest potential to impact your wallet. Treat the diesel fuel with a regular-use detergent treatment. This means your diesel engine and injectors probably have significant deposit buildup. And engine deposits in these areas can be a substantial drag on performance and efficiency. Investing in a concentrated diesel fuel treatment and cleaner like Dee-Zol can typically return 5 or 10 times the purchase cost in improved efficiency and equipment condition, provided the treat rates are concentrated enough to make the treat cost low.
Some fuel treatments whether for diesel or gas cost six or seven or eight dollars a bottle, but only treat small amounts of fuel like a one tank treatment for a car. The right diesel treatment, like Dee-Zol, will get the job done for ten cents a gallons or even less. I have no problem hitting mpg tanks in the winter jetta or passat, we just have to do our normal mile treck to visit family in Maine. But I'll get around 35mpg in my 2 mile commute to work. Thanks for the warning. I've always lost MPG's on any car that I have owned in the winter.
Air is more dense when it's cold, and thus it takes more fuel to mix with the increased air density and thus mileage goes down. I never let the car idle in the winter, it's part of the reason that I don't really understand the value of remote start in the winter. What we should have is remote heated seat activation and electric heat activation to melt ice off the windows. None :S. The shorter your commute, the worse the hit will be. Also a fair warning note for winter forum moderation I don't think any of us feels like looking at thread after thread about why fuel economy is poor, what to do to get it to stop being poor, how much VW sucks for this that and the other thing, etc.
All of this was discussed last year anyway - if you want to read it, search for last year's threads. Does activating the heated seat really decrease your fuel efficiency? How much of a draw is it on the electrical system? I never noticed an issue with my 05 Jetta.
The heated seats probably draw 50 watts each I guess not that much really. But it does all add up! My plan is to focus on just driving downhill in the winter. I will simply pay to have my car towed back to the top.
That should keep my fuel mileage right up there and help the local tow truck economy. Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds. In a previous breakdown, we talked about how tire pressure decreases in colder temperatures , thus increasing rolling resistance. Winter grades of gasoline can have slightly less energy per gallon than summer blends. Finally, your battery performance will decrease in cold weather, making it hard for your alternator to keep your battery charged.
This will also affect the performance of the regenerative braking system on hybrids. All this means if you notice that gauge dropping fast, or your MPG Range estimate on your car lower than the summer, just know that the cold weather makes your machine work harder, lowering its efficiency.
