Must first start off by saying what a great site. Recently purchased a 13 plate 0.9 twin air petrol and as I only drive through the lanes to work which is only 3 miles over the last two months my car seems to be flat. Question is, is the a quality additive that works that I am able to add to the two cylinder petrol engine to clean up the internals for smoother running.
 
Best stuff to put in is BP ultimate or she'll V Power fuel, they have built in cleaners.
Cheap petrol is what it says, new engine love high grade fuels :D
Has the advantage of burning hotter so faster heat up and better performance.

Also side note put in what your dealer sells it might cost more for same stuff but if something goes wrong they can't blame anything, you used their stuff :)

Welcome to the forum and the world of 500L ownership.

Just a thought and sorry to ask the obvious but you haven't inadvertently activated 'Eco' mode have you?
 
No have not did the first few weeks but found it terrible thanks for asking. Just looking for a good product to clean my little baby

Then I too would try the higher grade fuels before trying any additives. As you will know the twin air is a high very performance for its size engine and turbo charged aswell so it might appreciate the better quality fuel. I find it makes little difference to our 1.4 but they are based on pretty old technology compared to the TA, whereas the TA is pretty much as 'cutting edge' design as FIAT get.

If that doesn't make a difference I would be tempted to get it looked at particularly if there is any sort of warranty with the vehicle, or as suggested ask a FIAT dealer for an additive recommendation.
 
Additives are snakeoil, avoid. If the car seems down on power get it checked out, tends to be an underlying fault or even a good service. You need to take a holistic look at the cars system, get it checked professionally.
 
In the same area of query, our twin air 500l, 4 years 58000 miles. Just been serviced and runs sweet as a nut, good acceleration,good economy, pulls well at low revs. In 2 to 3 months after the last service engine begins to sound and feel harsh, economy becomes poor, not that its that good anyway and needs lots of gearbox work to keep pace.. Any suggestions please.
 
Sounds like you may have an underlying fault, that isn't quite broken enough yet to trigger a warning light or rear it's head!

Maybe try running some premium fuel and you could always buy a copy of ecu scan if your out of warranty to have a look yourself for fault codes logged or try an independent specialist fiat/alfa garage.

Did you last have your car serviced at a fiat garage? As if the service lights isn't reset properly this will limit the cars performance - I believe only the official fiat software or ecu scan can do this reset properly.

Here's multi ecu scan: http://www.multiecuscan.net

Holy thread resurrection.:) As said you need to get the car looked at, obviously something amiss. Forget any additives, waste of money. Sound advice from 1.8stilo.
 
All fuels have to meet a strict British Standard, so there is no such thing as cheap petrol, really. We simply don't get third world fuels in the UK.

But there is expensive petrol, which just have detergents and wotnot in them. There are also premium grade fuels for high performance vehicles.

Even supermarket fuels are often purchased from the cheapest available supplier on the open market. I have seen BP tankers and all sorts delivering to supermarkets so the adage that supermarket petrol is of a poorer quality, is not necessarily correct.

When I worked in Trading Standards many years ago, it was always interesting to see where the supermarkets got their deliveries from.

My twin-air 500L was a reasonably quick car with a huge thirst. Fun to drive when driven enthusiastically, but 6 gears meant I was always working, as was the engine and it could appear to be down on power even when it wasn't. It was woefully uneconomical for the engine size as well. I often only averaged 36/37 mpg per tank full.

Hope some of this info helped.

I can't remember where but I'm sure I have read that engaging city mode also switches the car to ECO mode without any indication, it is tempting in twisty country roads to lighten up the steering.
I have accelerated in a straight line in city mode and turned city off and I do feel a change in acceleration rate and engine sounds crisper.

not mentioned in the older part of the thread.. as the cars were too new then..;)

but the lighter bodied TA's seem to run rough with a failing spark plug..:eek:

and presumably you've just had the older (reliable) ones changed..:rolleyes:

Charlie - punto TA - 4 years 29k, and still doing 50 mpg:cool:
