Fuel Economy in Cold Weather

by

Cold weather and winter driving conditions can reduce your fuel economy significantly.

Fuel economy tests show that, in short-trip city driving, a conventional gasoline car’s gas mileage is about 12% lower at 20°F than it would be at 77°F. It can drop as much as 22% for very short trips (3 to 4 miles).

The effect on hybrids is worse. Their fuel economy can drop about 31% to 34% under these conditions.

Why is winter fuel economy lower?

Cold weather affects your vehicle in more ways than you might expect:

  • Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids.
  • It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures.
  • Heated seats, window defrosters, and heater fans use additional power.
  • Warming up your vehicle before you start your trip lowers your fuel economy—idling gets 0 miles per gallon.
  • Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds.
  • Tire pressure decreases in colder temperatures, increasing rolling resistance.
  • Winter grades of gasoline can have slightly less energy per gallon than summer blends.
  • Battery performance decreases in cold weather, making it harder for your alternator to keep your battery charged. This also affects the performance of the regenerative braking system on hybrids.

Unbelievable attention to detail and the staff is so friendly!! The owner - Chris, discussed with me what was wrong with my car and why. It's a very personalized place.They had to order the part for... my car and I called at 2 in the afternoon and it was there the next morning and instead of being told to come in and wait on it, I got a personal phone call & asked what time worked best for me. I wish service and personal attention like THAT was in more places!!read more

I've always had great service here. Very honest, they don't try and sell you things you don't need. My most recent issue was a transmission issue. So dropped it off so they could run diagnostics on... it. After they determined that I needed a new transmission they recommended that I take my car to the dealership. Knowing how stressful transmission issues can be they waived the diagnostics fee. Instead of spending the 2,000 to repair the trans I traded in the car for a new vehicle. And of course I will always continue to come here for my service needs and will recommend that people come here. They always go above and beyond. Thank youread more

Just wanted to take a moment to praise the service I received this morning. I just moved into the area about a month ago and Google searched for a shop when I found Car Clinic. I went in for an 4... wheel alignment job. Since my 01' 525I BMW had been in a wreck (Right Front - hit telephone poll) they took the time to explain and show me under the lift that due to the frame being pushed back; that it wont align perfectly straight.They even recommended me to a place to take it to have the frame straighten out however I do not have that kind of money for that job. I told them to just to the best they could. The alignment mechanic was very professional and explained to me that my car may pull to the right. However upon test driving the car everything seems great with no such pull and the wheel is perfectly centered! They also gave me a print out of the current alignment specs (Toe, Caster, Camber etc). Staff is very courteous and knowledgeable, wouldn't hesitate to take my car back to them - and I am very picky about others working on my car as I am a DIY kind of guy. Thank you Car Clinic!read more

Friendly and genuine people here. Great service today, and managed to take care of my needs faster than a name brand shop can find a way to overcharge me. Even having to have a part sent from a parts... place, I still walked out the door in record time. Fair price and took good care of my ride. Will be sticking with CarClinic from now on.read more

I have brought vehicles here over several years and have always been pleased with the work done. ... I trust their judgement and expertise.We have brought in beater used cars as well as premium new cars and even an old RV camper van that needed engine work.
