my gas situation
hey guys...i just want to know what my problem could be and how to fix it...well here it is. The past couple times i pumped my gas was around 1.24-1.26L always put around $30 in the tank, well i just wanted to check on my own how much each time the gas would last....so i noticed i could only get around 350-400 km from that amount of gas i put in my tank, now i dont think thats alot at all.
I've done a couple things this year to help my car -the frequent oil changes (high mileage oil) -radiator flush (4000 km ago) -transmission flush (4000 km go) I have a 1998 honda civic si with 218000 km, automatic, lowered with tien s tech spring, the tires still has alot of tread and nothing to the engine pure stock any thing else you want to know i can post back. now i just want to know what i can do without hitting my wallet to much |
well first of all you arent putting a full tank of gas in there...$30 in gas at $1.25/litre is only like 37.5 litres...you have space in the tank for 45litres +/- a litre or so...
|
i have a 40 L tank in my civic and it cost me $60 to fill it, and i only get around 450 km's to it. You can put a header onto it, that will give you a little bit more fuel economy.
|
$350-400 sounds about right for $30 bucks.
I get 500km on $50 bucks |

you have a turbo though..
|
Civics like most other cars do noticeably better on the first half of the tank. You are ruining your chances of good fuel economy by putting in so little.
|
exactly.. u should be filling up your tank to full before you start calculating your mileage.
Also making sure your tires are inflated to what your owner's manual says also helps. |

^^ also the tire compound is a factor. soft tires equal higher rolling resistance equal less fuel economy. look at smart cars they have really hard compound tires.

i get about 400-450 city driving i never hit 500 but most of my driving is city but if ur putting 30 bucks in and ur getting 450 u hsould be smiling plus i always hit vtec i juss love the accleration of first gear so i burn a lot of gas but w/e
tune up ur car and put the fuel injector cleaner in ur gas tank the next time u fill up all the way dont just stop at 30 bucks it costs me 45 -50 bucks to fill my tank and thats only if i hit like EMPTY the red line empty but i noticed a big difference when i put the fuel injector cleaner in |

i get 200 kms before the gauge moves off F, now I'm sitting at 420 kms and just over 1/2 tank showing on the gauge. last time i filled up, I was at 650 kms w/ 5.5 liters left in the tank.
Plenty of factors. |
last fill was 70% highway (by hours, not mileage), tires are bridgestone weatherforce, size 175/65/14 (EF sedan), tire pressure 38 psi (i keep it high for good mileage), drive 110 steady, Sunoco regular gasoline.

Actually, youre only putting in 24 Litres, youre not filling up all the way. |

Can you explain this?? I never fill up more then a 1/4
|
I have a question regarding tire pressure, the owner's manual says I should have my psi at 32. but this is with the stock tires. I am not running the same tires anymore, does this change my recommended psi or am I still going to be using the same psi as stated in the manual?

This 'trick' can be annoying but it is worth it. If you do this, the result is that the top half of the tank seems to give you much better mileage than the bottom half. You will get a much better picture of your actual mileage if you do this, as you will actually 'fill' your tank. I've averaging 700km+ on a 50L tank, with about a 50/50 mix of city/highway driving. I drive very relaxed, do not use A/C unless it's boiling outside, and accelerate mildly - anything to reduce consumption. Lately I've been using premium, which I find gives me even better mileage and better passing power on the highway. The other day I pumped an extra 9.5 litres after the pump first stopped. Give it a try, but make sure to watch your nozzle so that you don't overpump and spill gas (and waste your money). So, my recommendation is NOT to over fill your tank. |
^ I agree. Gas expands and the reason the pump automatically stops filling up is to give your tank that extra room for the vapours and the expansion/contraction in the gas tank during changes in temperature.

And to the O/P if you are near oakville. swing by my area.. and I'll check your car over. If you need a tune-up, ignition timing.. stuff like that. But it sounds like you should fill your tank up all the way.. then tell us how much you get per tank.

By doing this you are actually putting fuel in your charcoal canister which is being vented out.

I'm glad I checked this post because I need to fill up my car tonight. Wow... I'm glad I've only ever 'over-filled' my tank 3 or 4 times, otherwise I would really be mad at myself if I had been doing this for years. I cannot believe I didn't know this... seriously thank you guys for pointing out this STUPID move on my part. |
care to elaborate on this?

Your fuel tank vapours are drawn out of your tank to a canister (it may be different on certain cars/models, but I'm just explaining a simple system) There are a few soleniods that control this flow of fuel vapours. By overfilling your tank, the fuel must go somewhere, right? So guess where it goes? Past the soleniods which aren't meant to be submerged in fuel and into your charcoal canister. Under extreme situations.. it may even be drip fuel out of the vent valve. But I've never seen anybody be that stupid and overfill it that much |
you know how many vent valve solenoids I sell a week? hahaha atleast 10! all cuz people overfill their tanks too damn often...I fill it to the brim when I'm headed out on a long trip but regular fill ups are to when it stops and then rounded up to the dollar
|
hey i get about 700-800km per 50L tank. no one mentioned that how you drive is a key factor, if you start fast and stop fast, how much you idle, i do about 95% highway driving. if you are on the highway a lot and can use cruise control try that, also, look at the tire pressure, if you want to reduce pressure fluctuation use nitrogen to fill them. also look at your air filter and fule filter they arent too expensive to replace and are considered routine maintenance to good fuel economy.

They're common on pretty much every make vehicle. |
i work at a dealership now in parts and pretty much every make and model sold I've sold vent valve solenoids and canisters
