I'm curious about some simple ways to save on gasoline? I've heard that taking anything heavy out of the car, may improve gas mileage.

Sure, that's a pretty good idea. If there's something heavy in the car (a large backpack, or suitcase, or the like), it puts a lot of weight on the tires.

I've also heard, that gunning the engine and breaking a lot, can waste gas.

Yeah, that's true, but it's also just a function of having the engine revved up and using the wheels as an engine.  I doubt it would take more than 1% of the gas to do that.

That's also something I'd keep in mind. Gasoline has a high octane rating, but it is only needed for about two seconds at a time, as the engine transitions from one speed to another.  So you could make one small change that lets you save gas while you're driving, by slowing down your vehicle using a transmission control -- a cruise control or automatic transmission.  Then if you "mash the gas", you don't have to come to a full stop first.  Of course if you do drive a vehicle with a manual transmission, you can just take your foot off the clutch instead of coming to a full stop.  (That would still reduce gas consumption, but it won't save as much as your transmission control.)
