    Im using Civic SIR 99. Dati puro xtra unleaded lang pinapakarga ko pero I heard that mas maganda hatak ng XCS because of the higner octane number. So after madrain ng Xtra nagpafull tank ako ng XCS but nagkaroon ng different nginig orientation ung car. Medyo mas malakas at madalas siya.

    IS ist because nanibago ang engine or i have other problems na? Balak ko bumalik sa Xtra after maubos ung XCS sa tank ko. Thanks

    Obserbahan mo muna wala naman halos dapat pinagkaiba mas mataas lang octane ng XCS. Tignan mo iyong RPM gauge niya kung erratic o pabago bago o hindi stable kung naka menor. Paki post na lang result.

    Speed unlimited: Though di ko pa nakokonfirm now pero parang i remeber, medyo eratic at times ung needle pag idle. If this the case like you said engine problem?

    One more thing pagnakastop pero andar makina at kinakabig to left or right manibel may additional vibration sa steering wheel at kambyo.

    Ginawa ko lang last wednesday was wheel balancing at change to xcs kasi nabisita ignlesia kami kahapon malayuang trip.

    when i switched from unleaded to xcs then back to unleaded, i haven't experienced any problems with the engine nor on the performance on the vehicle itself. Engine is 2E tho'.

    baka madumi lang yung gas na nailagay, latak na lang siguro yun.

    To isa1023: yup same gas station. Advisable ba na i-top ko na siya ng new fuel o hayaan maubos? Naka 1/2 empty na siya now after the trip yesterday

    renzod10: I never had this feeling in my car before with xtra. I wanted sana to shift totally to xcs to get the advantage of higher Octane, pero parang nakakaphobia.

    if you're not satisfied with it, better if you go back to your usual fuel, in this case the xtra unleaded.

    di ka naman ata nagrrace, so okay lang kahit mag unleaded ka.

    or ...

    pag mga 3/4 nalang fuel mo, pagas ka ng xcs ulit pero sa different station.

    tignan mo kung may trak ng gasolina kung meron, ask the gas boy kung nakapagfill up na sila, kasi kung hindi pa umalis ka na at sigurado ako latak nalang ulit ibibigay sayo, madumi siya. kung nakapagfill up sila, pagas ka kagad, kasi bago nga it means, fresh at malinis pa
