Get an air intake to let that baby breathe. That could help a little...I have a 2010 Jetta Sportswagen and it barely gets in the 30 range during the winter is there anything i can do to improve the gas mileage for the winter like using a fuel additive

Forget the air intake. Your "baby" breathes fine. There's really not much you can do but get the car to warm up faster. This must be your first diesel: speak in terms of fuel ecomony, fuel mileage not "gas" mileage.I have a 2010 Jetta Sportswagen and it barely gets in the 30 range during the winter is there anything i can do to improve the gas mileage for the winter like using a fuel additive
cold engine = thick oil, longer warm up (more emissions, looser engine), and winterized fuel.Okay, I'm sure I'm missing something. Living in Texas, we don't see a whole lot of sustained cold temperatures, so I've not notice this phenomenon. But colder air is denser which aids combustion. That's the whole point of a cold air-intake. Shouldn't colder ambient air temps result in improved fuel efficiency? What's happening here?
Above is what I have done this past winter. It does help with warm-up time.To help you get up to operating temp faster you can install a "frost heater". This is a system that heats and circulates your coolant while you car is off. By setting it up with a timer so it comes on an hour before you have drive really helps. You will get up to temp (and have warm air for our hands) much faster than without.
Another trick is to cover up your radiator with some cardboard or corrugated plastic board. This will help reduce the amount of cold air that flows across your radiator thus keeping your temp at the perfect running level.
Lastly, run for a while with the vent on recirculate to prevent frozen air from coming into your cabin and across your hvac system. This will help your car warm up as well as keeping you a bit toastier as well.
I live in Minneapolis so every winter we see a few weeks below 0, this year we had 37 days below zero, 20 of them in a row. I know what its like to run a TDI in the winter months, poor fuel and frozen temps kill your mpg.
Also a good suggestion. On a really cold day with a stone cold engine start I'll drive in either Sport mode or Tiptronic I think it's called and shift up and down myself to keep the rpms up. I just don't do any Italian tune-ups until she's nice and toasty.holding the tranny in gear to maintain 2000RPM when you start it until you get up to temperature, will get you there much quicker in the cold weather
Oh, I forgot. It will get better mpg if you use diesel instead of gas. Yes I'm a smart ass.I have a 2010 Jetta Sportswagen and it barely gets in the 30 range during the winter is there anything i can do to improve the gas mileage for the winter like using a fuel additive
Will first off how fast do you drive MPH? When you drive the car do you drive in city traffic of stop and go only or do you drive mainly on the highway a lot?I have a 2010 Jetta Sportswagen and it barely gets in the 30 range during the winter is there anything i can do to improve the gas mileage for the winter like using a fuel additive
Check tire pressure. Remember that winter diesel has less energy content as they mix in #1 fuel to lower the gel point. In your region I think generally speaking you should expect a 10% reduction in the winter. Depending on where you get fuel too....those on highways or near them may tend to winterize further to keep it from gelling as the truckers and other diesels head north....which of course would further reduce fuel economy.I have a 2010 Jetta Sportswagen and it barely gets in the 30 range during the winter is there anything i can do to improve the gas mileage for the winter like using a fuel additive
