My own experience is that slowing down on the freeway isn’t going to make a lot of difference. The main way to cut back is to significantly reduce the overall quantity of driving. ie, don’t commute 40 miles each way to work and back. By limiting my commute to about 5 miles each way really helps.

Slowing down to the speed limit can make a huge difference especially if you drive a vehicle with poor aerodynamics (SUV). Every 5 mph over 65 mph will decrease your fuel efficiency by 7% on average. I used to drive 70-75 mph (when possible) and now that I’ve slowed down to 65 mph I’ve seen the fuel economy of my CR-V increase from 23.5 mpg to 26 mpg.

Another change that can greatly increase your fuel economy is to drive more smoothly, giving yourself space in traffic so you don’t have to brake and accelerate as much. This saves me a lot of gas driving to work on the 805, though it doesn’t seem like many subscribe to this theory. Most speed up to the car in front of them, tailgate, slam on the brakes, change lanes and repeat… then when I exit I see the same cars turning right on Mira Mesa Blvd so it doesn’t really get you far.

have u guys started slowing down or is it just me and a few coworkers.

Yes, but it's to avoid getting nasty tickets ever since they increased patrols on I56 rather than saving fuel.

 You're car's aerodynamics/weight has a lot more to do with it, which you really can't change. Also, you burn a lot of fuel from harsh accelerations, redlining, driving WOT frequently, which people don't really do (well at least most people don't do).

Personally, I'm trying to keep things lately on I56 to avoid the dreaded +20mph speeding tickets that don't usually allow traffic school, though interestingly in SD, they still let you go to traffic school if on the freeway you end up get clocked above 85 but below 100. Guess we need the revenue.
