ok so i just came back from a 1:30 drive and i came to a conclusion that the computer system is BS lol im just joking.
I took the car out on the freeway and i left it in 6th gear with cruise control on at 70 mph. i reset the computer by holding down the first button and i kept on driving. when the computer was done calculating i was getting about 36.6mpg and 69.5 mph. after few minutes it slowly started to go down to 33 and then to 30 and then to 29 and so on and on. after some time i started averaging about 24.5mpg and then 25 and then 26, 27, 28. so the highest that i had was 36.6 and the lowest that i had was about 24.5 on the freeway. It mostly depends on the road, if its bumpy and an incline the gas mileage gets less but if its smooth and a decline the gas mileage increases.
After an hour of driving on the freeway i decided to get off and drive on the street to see what happens. i got off the freeway and i started driving on the street. i wanted to reset the computer again so it starts off its calculation on the street. so i did it and when it came back on i was getting 33.6 mpg for like 5-10 minutes but then it went down to 28, 27, 25. the lowest i had on the street was about 22.3 but the average is anywhere from 24.5 to 25.2. i dont know if it will change tomorrow but after driving it for 30 minutes and going threw a good amount of red lights my average was 25mpg.
On the street when taking off on first i wouldn't let the rpm go higher then 1.5k. after 1st i would go to 2nd, after about 15-20 feet of driving on first. Right before i hit 15-20mph i would go to 3rd and go all the way to 25-30mph and i would skip 4th and go straight to 5th. and i was driving like that for most of the time. if i was approaching a red light i would go to neutral from 5th from far away and wait until it turned green and i would drop it to 4th and then 5th. I even tried 6th for few minutes but it didn't make any difference so i don't think we need to use 6th on the street.
so before i did this i was getting about 15.9 mpg now it says im getting 25mpg so give it a try and lets see what happens.
p.s. i probably would not be driving like this again because its so slow people might mistake me for a granny lol
