    Default Problems with my Civic 8Gen

    From the last one month i am facing few issues with my civic 2008 i-vtec.

    first one is that there was a rough noise from engine bay, took it to honda defense, specialist took the road test. Idle Pulley tensioner changed under warranty .. Thank God rough sound gone, less vibration inside car.

    2- Today again took my civic to Honda Defense -

    Reason - Too much Hmmmmmmmmmmmmmmmmm background sound whilst driving
    Again road test. diagnosed wheel bearing issue, ordered from Honda Atlas LHR, will get it changed in 2 - 3 days.

    Though car is a mechanical machine and things can go here & there, but this shows the quality of products they are using. I love my car alot but bit disappointed with the built quality. . but Thank God everything is covered under warranty.

    my ODO meter is jst 16.5k kms but 2 years completing in 15 days . so guys from your experience is there anything else i should tell honda to inspect so if anything is wrong they should replace is under warranty.

    thank you bro!
    btw does high RON fuel help at low speeds and low rpms as well or is it mainly helping to boost the performance at high revs and higher speeds ?

    Both actually.

    In standard test conditions which includes averaging of Highway and intra city driving, the fuel economy of Civic 1.8 is 14.8.

    Which means This car should give at least 10-12 km/l inside City and approximately 16 on highway.

    Link:
    Honda Car India :: Civic

    Similarly, we see video's of Civic 1.8 doing 236/240 etc on youtube. When our Civic 1.8s here in Pakistan start to die after 210. It is because of the above mentioned factors.

    Default to achieve higher fuel mileage:

    I am actually asking you if 90 RON or 93 RON is required/recommended for the reborn civic 1.8Ltr, is it recommended by Honda and all other gasoline engine manufacturers ?
    Quote Originally Posted by airomerix View Post

    thanks for clarification.
    Well yes agreed. however in my reborn civic prosmetic i'm getting 8.75 to 9.25 km/L only after i started using monolec EO which is the most-advanced technology EO with the capability to go up to 41,500-kms without needing an oil change. Considering the cost of monolec EO i will be happy to achieve even just 12,000-kms, because i'm also getting good fuel savings and a quieter running engine due to the friction reduction.
    (ps: in our GLI new model we already exceeded 14000 kms on monolec and just one filter change - oil condition is still quite good!)

    My reborn 1.8L also mostly does short trips daily... defence to defence/clifton/city center. My driving conditions are also extreme because per trip 4 kms to 7.8 kms only. daily about 20 kms max while occasionally driving up to 40-50 kms in one day (very few such trips per month).
    Originally my reborn 1.8L would also not go above 8.0 km/L no matter what, and actual previous fuel mileage was 7.25 km/L to 7.5 km/L with Aircon on/off.
    Currently approaching 14,000-kms odo reading.

    Default its a tough call why average still low

    so now why is my average still low ? ? ?
    looks like fuel deposits & accumulated moisture over past 2+ years are the most likely causes. i wud suggest to go on the highway (khi-hyderabad) OR early morning on shahra-e-faisal and drive for 30 minutes non stop at about 75 km/hr (preferably 90 km/hr) and then refuel with same petrol as using before. but really if this does not solve the issue and bring back mileage to at least 7.75-8 km/L with A/C on, few options remain.
    Because petrol you are using has RON of 90 and engine oil you informed is in excellent condition and if you are using OEM genuine Japanese oil filter and air filter, only 2 points remain:
    a) fuel system and injectors everything needs cleaning and deposit removal,
    and/or
    b) crank-case has deposits or oil flow is not sufficient to bring maximum efficiency from this engine.

    I know from other manual reborn owners that they get 10.2 to 10.8 km/L. I gues if you r traveling less than 5 kms each time, then stop for 20-30 minutes fuel mileage suffers but not so much as to go below 10 km/L in the reborn manual civic.

    Every time we turn off our engine, the last drop of petrol evaporates on the pintle of the fuel injector and leaves behind deposits and varnish. Heat in the chamber bakes the fuel residues and makes it stubborn to remove. This gunk collects on the pintle, and over time it results in injector clogging and leaking. The pintle caps are constantly exposed to fuel evaporation which leaves behind a powdery residue and affects the spray pattern. Usage of fuel additives for cleaning your fuel injectors is hotchpotch solution. It passes through the injector for a short time and makes little cleaning but on the other hand it is harmful for the fuel filters and engine itself. Therefore it is recommended to change engine oil after usage of fuel additives.
    I provide off vehicle fuel injector servicing on the same technology which is used internationally. The injectors are electronically tested, flow volume and spray patterns are analyzed and later serviced with the acoustic technology. The solutions developed for cleaning is aqueous and is higher than PH 7 level therefore it does not cause any harm to the injector. The injectors are checked again for flow volume and spray patterns after servicing and mounted back to the vehicle. I welcome your enquiries on fuelinjectors2606@gmail.com

    Default physical / acoustice cleaning of injectors is not a routine maintenance requirement!

    Thank you for offering your services, but please be clear when should these "injector cleaning" be done and which international engine manufacturer (if any) recommends this and at what schedule ?

    Please provide internationally accepted empirical evidence of your statement, otherwise what you are saying means that all the world's leading gasoline suppliers are wrong in adding additives to the petrol & diesel fuels !

    These fuel additives are acually necessary otherwise pure Raw fuels would indeed quickly wear out the sensitive injectors/nozzles and also the other major parts of the engines.
    Do you disgree with this ????!

    Physical Cleaning (Acoustic methods, etc) of injectors after just 10k or 20k 04 even 40k kms is not really required, otherwise it would be in the maintenance manuals of all Engine manufacturers.

    These engines better not be mechanically services internally untill at least 150,000 kms or more, because these are new generation engines with tighter design engineering for much longer life. In the end, prevention is better than cure and field-proven fuel supplements are the answer.

    Sirs 87 RON works fine on a R18, it is an average engine, nothing special.

    Even the ultra high compression 9,000 RPM Rotary engine of a 05 RX8 creates maximum power at RON 95, having a 3 way cat converter and Euro IV certified.

    My Mercedes M111 requires 90RON and 05 RX8 RON 95 but they also had a knock sensor and works fine on 87 RON.

    If a petrol pump is good and without impurities, 87 RON is more than enough and using anything above is just a waste of money on Civic or Corolla, same could be said about using synthetics.

    So unless the petrol is as cheap in Thailand as it is in Saudi Arabia or if the Thai R18 revs to 9,000 RPM, produces 250PS and has a compression ration of 11.7:1, there is no use for expensive petrol.

    There is no harm in both physical injector cleaning or using an additive.

    Physical flush machine has much better results.

    RE: RON spec of the petrol...
    Agreed - only higher compression engines would benefit from higher RON.
    Or the driving must be at very high RPMS and Speeds continuously.
    Both these do not apply to Reborn Civic and in driving conditions in Pakistan !

    RE: Cleaning the injectors etc. etc...
    It is all about the convenience and practicality of a given solution. I believe no one is against physical cleaning nor against additive based cleaning.
    - So at what ODO reading (kms) would you suggest to do the physical pressurized flush cleaning of the injectors ?
    - What is the cost of this activity ?
    - Is there a guarantee that injectors or any other engine component will not get damaged during this activity ?
    - Dont you agree that if cleaning effectively is done "while driving", even the need for the physical cleaning will be delayed quite far away than jsut 40,000 kms ?

    Dear Gferoz, the source of my knowledge is internet. We are fortunate that we are in the age when everyone has access to the knowledge of his interest. I myself had injector problem with my car and failed to find a solution even from the dealership. I read quite a few articles on the problems which included articles from high-tech workshop websites like 2carpros etc. I found many recommendations for injector cleaning after 20k kms. Please bear in mind the climate and fuel quality of American Canadian and European fuels, you can compare them well with our own. It is not my statement and I wouldn’t want to provide any evidence. Its all over internet and open to anyone who has interest in it. Had there been adequate amount of detergents in the fuel, there would be no injector clogging and no requirement of cleaning. I was referring the fuel additives which are in the market with different name and are meant to be used when the injectors are gone dirty and causing trouble not the ones which gasoline suppliers add to their fuels. I agree with you that the detergents are essential component of fuel.
    Keeping exceptions aside, a car can keep on running for 200k or might even more without injector cleaning. But the scaling in the injectors never stops. Its more so with the car which ply for short distances in one go. Because they start more often and turn off more often and every time they stop the petrol dries on tiny nozzle of the injector and leave behind deposits and every next time the engine starts, the heat makes it more permanent. The user can’t realize it because his car is running. But this clogging reduces the pickup of the car, effects fuel economy and makes it unfriendly environmentally. Knowing this you can decide for yourself if it is really required or not. Don’t expect much from the car manuals provided to us in Pakistan. We are a simple nation therefore the cars provided to us are also simple (I am sure u know that how our Corolla differs from the corolla that is made for Europe or America and any other car for that matter  ) and so are their manuals.
