Cooler temps, less mileage

[jraynor196]

So, for October in New England we had about a week of 30 to 40s and I am sure some of your saw the 59-0 blowout Pats game with the snow so its been cooler and downright cold for a few days and it is not even winter yet.

When the temps were in the 30s, I dropped about 5-10 MPG.

For example: today it was 60s to 70s and my commute was 62.1 going in and 60.5 coming back.

When it was 35 to 45 my commute was 51.4 going in and 50.1 coming back.

I am garaging right now and garage is about 10 to 20 degrees warmer that outside temps, so I am not seeing too much of a increased cold to warmup time, but that may change once we start having the hard freeze.

Did you check your tire pressure?

We had a bit of a discussion on this thread.

How much does weather impact MPG?

j - What was your driving style like? I happened to be in NH and MA during the same time period. Going up and down I-93 and related non-interstate driving going 55-75mph netted me 41mpg on the snow/slush day and, like, 43mpg on the "warmer" day. This includes some warm-up time since I was parked in my friends' driveway the whole weekend.

Getting out to NH from OH, I got about 40-41mpg in 32 degree (morning) to 54 degree (evening) going at an average 75mph. The trip back was 42.5mpg in 50 degree (morning) to 70 degree (evening) weather going the same speed. I would have been more fuel efficient and slow with my driving if I hadn't been hauling three other people.

ps- I made it across the state of NY along I-90 on one tank of gas going 10+ over the speed limit. Total fuel cost to do it was $26. That's amazing to me! I used to make the drive in other cars and had to fuel up more than once on the NY Tollway paying +$.20 above the national average.

I drive slower than most people (55-60). Also I drive like my car is on a roller coaster. Speed up going down hill, slow up going up hill. New England really hilly so going a constant speed not an option for high fuel economy. So, my speed is constantly fluctuating depending on the grade of the road and preparing for the next hill climb. So, I use the momemtum of going downhill to help get me up the next hill.

One day it was really cold and there was a stiff headwind, and I barely got out of the 40s, MPG wise. So other factors involved as well.

1-6x17" cardboard piece & +10 MPG! Yup no lie
This free mod has helped improve mpg in cold weather. Helps to have a scangauge to monitor coolant temps.
As long as windows are clear to drive safely a car will warm up more efficiently if you start driving immediately.

I saw this the other day with trolling in the I1 section. I was trying to measure and figure out how to do the same on the I2.. The space is tight, and around here you don't want salt etc stuck on that cardboard promoting rust so it'll have to be some kind of plastic or light metal. Right now still trying to get a baseline of mileage from ym normal driving habit + fuel grade.
