Fuel Economy

[DreagonR]

Hello everyone... I just recently Drove from Toronto to Conneticut and since i had to drive on the i90 for around 490km i decide what better way to measure my MPG. Well it turns out i did 145.08 miles per 4.498 US gal.

145.08 miles / 4.498gal= 32.254 miles per gal.

17.02liters / 234.0km *100km= 7.274 liters per 100 kilometer.

Which is pretty bad considering Toyota advertises their fuel efficiency at
40mpg on highway.

By the way i have a Manual Hatchback, and yes i did have my AC on... so that should also take up a few MPG but i can't even get close to the 40mpg that Toyota Advertises. Even with the AC on that should only add around 10% of fuel consumption which would bring me up to 35.479MPG. still no where near their 40MPG advertise. I'm wondering if my car is defective??

I have Synthetic Oil in my engine and I recently checked my tire preasure... which is to manufactures recommendation.

this just confuses me too much...

my car has already been broken in... i have around 20 000 kilometer on it.
