I just remembered an old trick we did to save gas during hard times, & the 70's oil embargo. I added this " trick" to both cars. It costs= NOTHING. Take a piece of red tape,[ you can paint any tape with red fingernail polish] & apply a small piece right over the best overall gas saving speed for your car, on the sapeedometer face. Most all cars get their best mpg at 55-60mpg. YES. YOU CAN DRIVE 55 !! When you look down at your speedometer & see that the needle is above that speed,,, just slow down. Get in the habit.Keep the speed at or just below the " red line". You will quickly adjust to it & will be normally driving that speed in no time at all!! My mileage on my small car, doing this the past week , was 44.6 mpg.[ it usually averages 38mpg] Sure, not every car can get that kind of mileage, but you WILL SAVE,& you will save a LOT & it doesn't hurt you.If everyone did this, we would save a tremendous amount of dependance on foreign oil! Try it & report your findings!
