The diameter of each wheel of a bicycle is 26 inches. If you are traveling at a speed of 35 mph on this bike, through how many revolutions per minute are the wheels turning?
NONE. You car already burn 99% efficient. You need more energy to get more MPG. So all those other INCREASE YOUR MPG gadgets are scams too. There are few thing you can do to save (or maximize) gas MPG. First get a tune-up. (1) spark plugs (2) spark plug wires (3) distributors, coil, rotors (if you have them). (4) new air filter (5) PCV (6) correct tire pressure (7) clear the trunk of useless heavy items (8) spray clean MAF sensor. Forget all those SAVE GAS scams. This was on NBC morning TV show. The difference is as much as 38% (their claim). There are very simple rules to save gas: (1) drive slow - not too much past 55 (2) accelerate slowly (3) don't brake unnecessarily (4) use cruise control - whenever it is safe to do so. Don't coast - it is NOT safe (to coast in Nuetral) and it does NOT save gas. It only saves gas, if you are planning to slow down (exiting, tolls, traffic). Coasting then accelerating again is LESS efficient than just cruising. The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic). That's 41 MPG (94 Civic 187K miles). Actually I was speeding at 72 MPH so I could do even better at 55. WOW !! Good Luck.
They are ALL a waste of money (as far as gas mileage) However, Lucas Fuel Stabilzer is GREAT for cleaning dirty fuel injectors. The notice in mileage will not really be noticeable though.
