When you cost in neutral, your car uses gas to keep it's idle, but you go a little farther. When you coast in gear, you use no gas, and you supposedly go less distance (I havn't really noticed). Everytime I drive to a red light, I start coasting in gear early and get into neutral when I'm almost at the light to prolong the in-gear coasting.

You should learn how to drive predictably so you can replicate your results, then compare the difference in mpg from you changing gears at 2k vs 3k. Most of getting a high mpg just involves you driving at a constant speed for as long as possible, and reducing your accelerating amount.

I hit 30mpg almost every single gas tank, but I've been practicing for a long time, and I used to have a air fuel gauge/boost gauge to stare at when driving my old car to make sure I kept my foot steady

When you coast you mean when you're letting the car roll without pressing the gas pedal and in neutral ? Sorry
