Question

What is something that i can add the my car to make it more fuel efficent?

Answer 1

Just switch to LPG already xD

Answer 2

All of the fuel additives out there either don't work, or are harmful to your vehicle's engine.  I suggest avoiding them.

Answer 3

add more air in the tires and clean the air filter... other than that no

Answer 4

Pump up your tyres just over the recommended.

Go easy on the gas and use the gears to get your speed up rather than compensating with the throttle.

NO coasting downhill, it uses up less when the wheels are keeping the engine turned over rather than gas.

Stay in a high gear if you can get away with it, but not so much that you have to compensate with using more gas.

Don't over rev, but make sure you get to atleast 3500rpm first.

Answer 5

try doing a lot more coasting, you'd be amazed at how often we use the gas pedal when we dont need to.

I got about 75 more miles to the tank when i tried it! it works for sure!

Answer 6

Redex petrol or diesel treatment. It helps maintain the engines high performance by keeping fuel intakes and sparkplugs cleaner. It decokes....Its a bit like having a mouthwash that reduces the plaque build up. Pop it in every time you fill up.
