I purposely drove slower this week to see how much it would affect gas mileage

My daily commute consists of 95% highway and with my current hours, I don't much traffic.

Usual rate of speed @ 75-80 mph gets me about 38 mpg during the winter (summertime is considerably better).

My average speed this past tankful was about 55-60 mpg. I got close to 41 mpg.
So a difference of approximately +2 mpg.

It was painful at first, but I got used to doing the speed limit, not on the far left lane of course.
But cars were still riding my ass, highbeaming me, giving me the finger as they passed, lol.
 
Try driving 25 in 5th gear the entire way. Or ride a bike.

It's all about time savings. If 2 mpg is worth your time, then go for it.

Say you're driving 60 miles. That's 45 minutes @ 80 or 1 hour @ 60.

15 minutes each way, 5 days a week, is 2.5 hours per week, saving approximately $2.76 in gas per week (assuming $2.39 per gallon).

Is $2.76 worth 2.5 hours to you? That's like a dollar an hour!

Well, tough question to answer.
I haven't timed it, but I would guess it's an extra 7-10 minutes to get to work, which is about 38 miles away.

As far as savings go, at 38 mpg, I would have to fill up once every 5 days.
41 mpg, I can fill up once every 6 days, so there's time savings in not having to go to the gas station as frequently.

At 15k miles a year and $2.50/gal, an extra 2-3 mpg probably saves me $75 a year 😛

I also have peace of mind in not having to worry about cops and speeding tickets.

Used to do 9-5pm, now doing 10-8pm (extra hours OT).
It's pretty clear on the GSP at 9.30am and even more dead at 8.30pm.

optimal gas mileage for US transmission is 55mph

I think when people advocate this driving slower, they are talking more about the collective savings of all the people commuting. Imagine that $2.76 per week savings multiplied by say. . .100,000,000 people. That's 276 Million dollars less worth of foreign oil we have to be dependent on as a nation each week. . .Like a $1 Billion per month. It adds up. You have to think about the big picture and about what's best for America in general. Not just about yourself.

[Edit] And please don't take these figures as literal. ... I'm just illustrating a point. I'm sure they aren't 100% accurate, I just pulled what seemed like reasonable numbers out of the air. I'm sure that the actual savings per week would vary from person to person.

Not exactly. 100% of that 276 million dollars doesn't go to the foreign oil interests. I forget what the exact percentage is, though.

I speculate he has a Prius or Civic Hybrid

EDIT: I was wrong

That's the awesome part.
I get hybrid-like mileage without paying the premium for the car (obviously not as low emissions as a hybrid).
Best part is I only paid $1500 for the car.

And mileage gets even better during the summer. I get around 43 mpg, max I got was close to 45 mpg.

Wow, thats a good deal for 1996 sentra. I should look into getting one. How can you drive in NJ without AC on in the summer?!

And you should have less of a chance of an accident if it weren't for the morons (like you in the past) who feel the need to drive too fast.
