    Slow down 306

    This past week, i've noticed my 306 xt feel alot less powerful. There is no way i can measure how much slower or less powerful it has become however i feel a definite loss of power, nothing significant however it is very easy to notice.

    Of late nothing serious has occured engine wise, i just got it serviced 300kms ago.I've had problems with the fuel gauge though, im not sure if this anything to do with that?

    What do you guys think it could be?
    any comments would be great!
    regards

    Do you trust the machanic? if yes you can skip the following points to check.
    1.Spark plugs
    2.Fuel Filter
    3.Air filter
    4.Correct "weight" oil put in

    How many km's has your car done? The following "may" be in need of replacement.
    1.Spark leads
    2.Injectors cleaned

    Are you using brand name fuel? Optimax, BP Ultimate98 etc may be a way to go for few fuel tanks.

    ahh, to the replacement list you can add
    3. Exhaust system, specially the CAT converter. But that would be a gradual loss of power rather then all of the sudden kind of thing.

    I would think the most likely cause would be a bad batch of fuel.

    Maybe a wire left/knocked off of a sensor somewhere causing the ECU to go to limp home mode, or at least the wrong management settings?

    Now that i think about it, since i put a full tank of synergy last week, the car has slowed down. Funny thing is i've used all premium fuels and found that Synergy worked best and was most responsive. Could this just be a case of poor fuel?????
    i've used synergy for about 5 months now

    Id stick with the bad fuel, run your car till empty then it may be worth while putting a new fuel filter in, and try running some different brand of fuel such as BP or shell.

    Give that ago and see how it is.

    Asanka its an 8V what do u expecr.lol

    Na seriously...maybe the fuel.
    Other have said the cat and it may actually be that. On my Uncles Mi16 the honeycombs in his cat had collapsed and his car was running like a pig struggling to rev ect.

    We pulled his cat out and found that it was blocking the exhaust...we gutted it and it was back to normal and the car revved freely

    Naturally you got a replacement cat as to run without one may well earn you a severe wallet thining. Makes a wife look cheap if the EPA catch up with you.

    I would have good and bad weeks with the GTi6 (some may remember me posting a thread a while back asking if their cars were "moody"). I ended up avoiding a couple petrol stations, mainly non Ultimate BP stations and some Shell Optimax stations, and tried to get Mobil Synergy or Ultimate as much as possible. Since then, and using an Amsoil fuel additive, the car very rarely has a moody day.

    Up until then I just thought it was a French "character" thing. dead

    Thanks for the responses guys,
    I spent yesterday trying to get rid of all the "dirty" fuel once i did this i dropped into to shell and got a full tank of optimax.I never really got a great response from optimax fuel before but this time I could really feel a stronger response, so i'm certain it had something to do with a bad batch of fuel.

    Lincoln could you tell me a bit more about the Amsoil fuel additive? Is it like that spitfire stuff you put in before you fill her up?

    Asanka, our mechanic uses it to clean the fuel injectors on every service, then you add a couple quarts to every tank of fuel. It basically helps lubricate the valves from the fuel which is very corrosive.

    Here's some omre information on it:

    GTI124 he's now gone to NEO as its similarly priced. But the Amsoil is great stuff I've noticed the difference when using it and now that I've run out the car just doesn't feel the same. I'll try the NEO next see how she goes.

    $20 for 4-5 tanks. Other brands are $10+ for 1-2 tanks so well worthwhile.
