Fuel Saving Tips
While most will say to always coast in gear, in most cases this is true. There are times when you will save more fuel if you put in neutral(manual cars). I have a couple stretches of roads where I can coast at the 30 mph mark due to neighborhood roads and if I keep it in gear it slows the car down. I do the surge and coast method of put it in 4th and get it to 30 then take it out of gear and coast. Engine load does go up but due to how long I can coast, it is more cost effective to let the engine hit load and coast for much longer.
