Got my NAH on December 1st and just filled my tank for the first time. My MPG calculation came out at 29.8, which seems a bit low. The computer's estimate was 31.5. Since I've hardly driven the car this month when the temperature has been above freezing, I was wondering if the cold temperature is to blame for the somewhat dismal fuel economy, given that I've been driving the car rather wimpishly. Driving has been split 60/40 country (45-55 mph)/city (30 mph). Has anyone here made any comparisons of fuel economy between winter and summer driving? And what have you been getting for MPG?

Replying to: emgr (Dec 23, 2007 12:57 pm) I've made about 3000 miles so far and did notice lower mpg in cold weather. For starters your engine has to warm up = wasted gas. And if you use heat, then the engine will keep running even if it's warm, while not moving for example. Turn off the heat and the car shuts off. Good thing for the heated seats. Putting better gas and changing oil won't do much to boost your mpg. Some people have been getting even 36pmg from day one, but looks like they live in warmer climates, ie. CA, with better roads. I'm in NY, and depending on driving would get 31-36, mostly it's 32-33. That's for 80% highway at high speeds. I make up for it in the city. Still better efficiency then V6. Enjoy your hybrid, karolpl7

Also have 2006 Sentra 1.8S.....before Nitrogen, it was at 30mpg consitently....after Nitrogen 32-33 consistently during spring/summer.

I have a blog entry about it... Nitrogen: A Noble Gas?

Replying to: pf_flyer (Dec 25, 2007 4:35 pm) As you nicely explained in your blog, Nitrogen will take longer to escape from your tires since the molecules are larger, therefore your tire pressure will be more consistent... and you will get slightly better gas mileage. Over 3/4 of air is already Nitrogen anyway. It's just another way for the industry to make money of you. Just keep correct tire pressure, case closed. Paying extra for Nitrogen makes no sense. If it's same price, then sure why not. |
