    Periodic maintenance and tuning involves change of air filter + oil filter + mobiloil every 3 month or 3000km whichever earlier. but if your car is not much used you can extend it up to 6 months no more.

    If your car has fine idle rpms under 1k without a/c and no jerks, then it requires no further tuning. if there is an issue like rpm drop or high rpms and jerks etc, only then tuning involve carb adjustment in carby cars and computerized tuning in ecu based cars. a device can be installed at exhaust of car to analyze proper ratio of fuel-air or other problems on carby cars.

    Dear respected faheemakbar18,
    OK I have air filter ready to change. I bought guard @350,
    Oil filter I will change with engine oil after two months insha allah as I have recently changed it.
    Spark plugs are also ready with me to replace. I bought denso. Many says NGK is good. What do you think?
    I noticed RPM remains under 1000 in the morning it was adjusted some time back by the mechanic under air filter box.
    Brake oil, respected saboor73 said should be changed after an year so I think this is a right time to change however it hasn't reduced yet. U can recommend a good brand for brake oil.
    Please tell me if I have forgotten wrote any important point. That would be highly appreciated.

    @saboor73 is much more senior person than me. and has taught me alot. I guess your choke is not working as rpm at morning/cold engine should be higher to heat to engine to ideal temperature. Dont wait for any oil to reduce its capacity before changing.
    I will leave it at saboor to suggest you oil brand for braking. For mobil oil. use only 10w40 or lighter oil. api grading should be sg or sj.
    API SL/SM/SN are not meant for this engine and causes wear

    Yes agree saboor73 sb is the most senior member.
    U know what earlier in morning start RPM was higher than 1500 I asked my mechanic why is going high as it always remain near 1000. So he set it on under 1000. I made a mistake?

    If rpm remains under 1k on cold start most probably auto chock is not working ask your mechanic to fix


    About brake oil buy any good dot3 brake fluid and brake fluid isnt changed accord to color or mileage its should be changed every year because it absorbs moisture with time

    Dear sir
    Thank you
    I made a mistake. before RPM was 1500 or higher but I thought there is an issue so I asked my mechanic to sort this. So he did something near air filter box. When I started my car it was under 1000. If auto chock is not working then wat kind of issue I can face?
    Will appreciate you guidance.

    1500 everytime? If so mechanic actually tuned it. Just ask him to fix auto choke. And idle on start of hot engine should be 1k or less

    Yes before in between 1500 to 1800. Then adjusted to stay under 1000.
    If I tell him to fix auto choke, he doesn't have a sense to fix it. anyway I will tell him. But I know his answer 'NO NEED'

    Hahahah very true. Mechanics logics are absurd and they hate thermostat valve and auto fan as well.
    If he show this behaviour try to get it installed through reliable Suzuki 3s center in your city

    Follow the upper pipe flange of radiator and you will find it just before engine.
    Its function is to stop water from entering radiator until it exceeds 88c (in cultus). If removed, water keeps circulating between engine an radiator and reduce temperature more than desired limit. It helps alot in winter and increase engine efficiency and life.
