Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by oblo(m): 5:40pm On Jun 17, 2010 |
Still on my golf 3. I noticed that my fuel economy is a lil bit on the extra high side( I am aware that its a lil bit higher than jap cars neway) Took a trip from abeokuta to lkeja in lagos ( regency halls) wch is about one hour and bought 30 litres before i left abeokuta. By the time i got back to abeokuta my tank don enter red!! Note that I ran the A/C to and fro but e go still chop that much fuel? A whole 30 litres!!Haba!! Wetin!!!!!! My tyre pressure was checked before the trip and I had only 3 passengers making a total of four persons in the car. So since I be more or less a DIY person I was thinkin of removing the catalytic converter from the exhaust system to reduce the back end pressure which in turn will make my engine run with less stress thereby improving my fuel economy, chei!!abi no be so?( I no be scientist jare!!!) Or there be any other thing or possible problem I might be missing? Sienna,kunle,,gurus dem in da house Please advice. Thanks |

Firstly, what's the rough distance between Abeokuta and Ikeja? We're talking approximately 6 gallons of juice, or assuming you were above the reserve (approx. 4.5 litres) so all in, approximately 7 gallons. Now for your catalyst. . . Sure, removing it will create less back pressure, but a naturally aspirated engine needs some degree of back pressure to run at it's most efficient, unlike a turbocharged motor, that responds best to positive pressure. Catalysts have come a long way since they were first mandatory on European cars (August 1992) and as such, are less restrictive than you'd think. Unless yours has broken up, and the core has partially blocked the exhaust, removing it will make little difference. You could also trigger a CEL (you don't say what country your Golf III is from, and engine size). US-spec cars have a different emission control system, compared to their Euro counterparts, and as such, are more sensitive to changes. I'd check your car for fault codes, before proceeding further. Is your car OBDII - as in does it have two lambda probes, before and after the catalyst? |

Also, in addition, Whats the traffic like?. If you are sitting in heavy traffic for a long time, then the distance don't really matter. You can run out 30 litres of petrol in your driveway with your a/c on! You didn't even move any distance. When was the last time your car was service? I mean full blown service. Plugs, spark plug wires (unfortunately most ppl think that they last forever!), fuel filter, timing adjustment etc. There is a lot that you might need to be concerned about bigger than your catalytic converter. Let us know. |

Siena: How do i know if its OBDII? And what are lambda probes and what do they look like? Kunle-A: |

oblo: @Oblo Your car is ok. I know you alway like doing all kinds of upgrades to it. With the kind of things you keep trying to do with this your German machine, its clear to me that the only time you will appreciate your car is when you damage it completely . People have very very serious problems like knocked out engines, bad fuel supply, vibration, etc - BUT you, your car runs and drives very well, you are either thinking of doing some injector "implant" or some catalytic "botox" on it. The truth is that Im not sure you can find a perfect car. |

Just joking, BUT really, your car is ok. |

Onwan: Phew!!! But u sef check am now?,,,,,30litres no too much? I for just kuku fuel my Vbug 1500series take waka the waka !!!! |

oblo: I hear you sha. Just check for leaks and service the moto. But e be like say DIY dey catch you for body , There is something a guy advertised on nairaland.com for fuel saving, I read online and users actually talked about 25% - 27% improvement in gas mileage (even for a big guzzler like the Hummer H2). I think you should give it a go. |

Guys i know it's not proper to bring dis up in som1 else's post but i realy need help wit my 04 EOD, WENEVA MY AC IS ON IN TRAFFIC OR I BUMP INTO A DITCH MY AUTO GEAR JUST DISENGAGES & I'L NEED TO SWITCH OFF & ON THE CAR FOR IT TO WORK, MY STEERIN OIL IS LEAKIN THOUGH COULD IT BE DAT? |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by Onwan: 9:40pm On Jun 19, 2010 |
thonerow:From what you posted, there are two different problems you are having; the leakage from the power steering system (which could be a simple hose issueor a the pump) [b]AND [/b]the gear problem (which from what Im seeing is a common problem with the Honda). I know someone who can look into your power steering problem and in the same workshop, they can get your gear looked into or serviced. |

You are changing your plugs too often Check the following plug leads ie wires for signs of cut, check the resistance per/feet Check that your aircleaner is okay and not choked |

Ok point taken ooooo, bt hmm my 30litres |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by Onwan: 7:33pm On Jun 21, 2010 |
@Oblo Just one more thing - Try checking through your exhaust system thoroughly for leakages (holes); pipes, pot, especially the gaskets at the joints, they actually have a direct effect on the fuel consumption. Cheers |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by thonerow(m): 8:44pm On Jun 21, 2010 |
@Onwan, tanx a lot, problem is i'm livin at far Benue-makurdi, plus a mechanic here says i need to replace my steerin box, and my gear box sitting, i'm stil confused as i heard its common & usualy d gear kit, pls help houz |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by Onwan: 9:22pm On Jun 21, 2010 |
@Thonerow Actually, he might have traced the leakage to be from the steering box and he also has a point with the gear sitting (considering it happens when you hit a bump or run into a ditch). I reason with him quite well. |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by oblo(m): 7:13am On Jun 22, 2010 |
@ onwan The exhaust bin no day leak o, ok i will double check, and God help that exhaust if i find any hole!!!!! ! I will #@#$$%%%^^&&***(( |

Good topic for the section- 30ltrs for a distance of 194km for a Golf is rather high, as against what the manufacturer says it can do. from the calculation, you burnt a liter for every 6.5 km, firstly, ve you been buying fuel from that Abeokuta fuel station?- did you observe your guage after the 30ltrs was poured into ur tank? from your post, you are suspecting the catalytic converter as the cause of poor fuel mileage- b4 dis conclusion, are you noticing loss of power from your engine- (poor or slow response as you accelerate?) your catalytic converter blocks easily when 1. your engine was smoking before (blue smoke) 2. whenever you steam (warm) your car in the morning, you dont steam it thoroughly or drive off as soon as its started. (condensed vapour can block the catalytic converter). DIY- you can clean the air cleaner or replace when its due, confirm your spark plugs and make u try find the one wey come with the car if possible- (preferably that with double electrode) I am damn curious and cautious on wastage wrt fuel on vehicles, I get approximately 310km from 28ltrs of fuel with a 1998 camry, (Lagos - Benin), when I drive steadily and softly on the throttle, I burn lesser than 28ltrs for same distance. 1st suggestion therefore- enter NNPC filling station, buy same 30 litrs and do same journey then revert. all d best |

I have repeated the same journey ooo. The exact same journey . The same thing happened!!!!1 So wetin next now? 30 LITRES TOO MUCH JARE!!!! |

oblo: You are forgetting to say how many kilometers Its hard (if not pointless) to determine the efficiency of the car if we don't know the distance. |
Re: Sienna: Kunle: Gurus: Catalytic Converters: Beneficial To Remove? by oblo(m): 7:38am On Jun 28, 2010 |
About 100 klm. |
