How do you check the fuell efficiency and which method is accurate
Have you ever had question like how do you check the fuel efficiency of your vehicle , have your peers told you various methods to check efficiency.
What method should you use ? Which one gives correct figures? If these are questions running in your mind then you ‘ve came to the right place
Welcome to THE AUTOMOTIVE INDIA and this is afrose3 , so how do you check the mileage of your vehicle ,tankfull to tankfull or that worderfull bottle method. In this thread I will be sharing my experience that I had and you will come to know why everyone recommends tankfull to tankfull method .
So I started today and I was curious to try I took a 2lt bottle with me and got it filled with petrol and went to the outer ring road I drived my car untill it was out of petrol . I gave it a few cranks to make sure that it out of fuel I agree im dumb
and stopped the car downhill ,this was my first mistake came out of the car and poured exactly one litre in the tank and cranked the engine after 6-8 cranks the engine started and I started driving at 40kph . To my surprise it stopped after 24.7 km .
Then again I gave some 8-10 cranks to make sure that the fuel is finished. Now here starts the adventure , so got out of the car and poured the rest 1lt petrol I had and started calculating that how I got so good figure I thought there must have been some fuel left even after cranking while thinking I cranked the engine no it refused to start. Then cranked some 8-10 times still of no use now I started worrying. This was my second mistake.
After cranking the engine so many times the battery came down. Now I told to myself that I had done some thing to it and lets start it by bump method ( I don’t know how to start by this method) so pushed the car and sat inside quickly and removed my foot from clutch still no use.
Then came a good Samaritan in type 1 maruti 800 hoping that he would help , I waved my hand to get his attention. He was around 55-60 years . He came and asked to open bonnet and tried to find out the fuel line that goes to carburetor but couldnt and told that petrol must come out of it when I crank and asked how it all happened and after listening that he got frustrated and showered lecture on me telling that “ you boys of this age always want to take risks and think of becoming noted every where for your risks , here it is take this adventure “I simply nodded to him then he told me he would drop to near by local mechanic but I refused .
Then came the second good Samaritan in zen D as I was pushing the car up to try bump start he parked his car and came to me and asked what’s the problem I told him everything , then he said have you tried bump start I said no and gave keys to him and pushed the car and voila it started and stalled then again pushed with all force and it started again , then I asked him how he did that he said I cranked so much that the fuel line was filled with air then my common sense came to light.
I thanked him from depth of my heart. then I told him about the air lock, he told that the bosch pump would lock and I don’t need to worry and asked me to check if it stalls again but it dint stall this time and i reached my house safely.
That’s how it ended , I would never recommend any one to go with bottle
1) Why shouldn’t I go for the bottle method and why only the tankfull method?
Ans : The bottle method is risky business to deal and since petrol is volatile it evaporates more when there is more space in tank and where as if tank is full or half the rate of evaporation is far less.
2) Oh I cant wait so long to check my FE what shall I do?
Ans : After you get the tank filled drive atleast 100 km so that you have consumed 5-8 lts so that there is room for fuel go to petrol bunk and fill the tank. Now divide the number of liters required to fill tank to full by 100 since you have driven 100km. There you that’s your FE.
3) I’ve heard people telling to remove unnecessary weight to get good FE , wont a full tank be unnecessary weight?
Ans: Yes removing unnecessary weight indeed increases FE, but there’s not going to be that much appreciable change and it is better than keeping half tank empty for evaporation and far more better than that bottle method risk.
4) How do I manage to get good FE in traffic?
Ans: If there is bumper to bumper moving traffic drive at a constant speed of moving traffic in correct gear .
