I am also using many automotive products and I was also tired of maintaining the fuel in those products. But later I got many things or points to be noted to save fuel of your vehicle. Some of the points as a user for saving your fuel for long period of time are as follow;
[1] Maintain your speed in the economy level in your speed meter.
[2] Don’t allow any other unwanted person to run your automotive product.
[3] Check your tires condition.
[4] Check some fluids necessary in the parts of the product.
[5] Don’t leave your product in start condition.
[6] Maintain your motor.
[7] Loose some weight.
[8] Be a smooth operator.
[9] Don’t be idle.
[10] Avoid traffic jams.
SAVE YOUR FUEL.! Thank you.
