Filling up and fuel guage questions

I have a similar prob with the 355. I suspect that it is a fault, but probably one that is easily rectified by clearing a vent or somesuch. (Over to you, Dale?)

As I understand it, there's no particular advantage in using SUL in modern engines, but EVO magazine did a test with Optimax vs Premium, which showed genuine and proven benefits in engine cleanliness and power from Optimax. I use Optimax although it costs more- only a small incremental extra cost compared to servicing and insurance!

This is a common problem with modern Ferraris generally.

The next time you take it in for a service tell them.
I think it's pretty easy to fix.
It probably just needs recalibrating through the ECU or needs a new sensor or something.

I have read about this problem many times on the F.Chat General Pages.
Do a search under Fuel problems with 550 or 360.
You should find something.


As far as which fuel to use.
Stangely enough Ferrari recommend standard unleaded (95RON)
not the super unleaded or Optimax (97RON).
I think it has something to do with the way the engines are set up.
In older cars you could actually do it more harm by running a higher octane petrol.
Altough it shouldn't matter in newer cars as the ECU compensates for
any variations in Quality.
But certainly for road driving (even aggressive road driving)
don't waste your money you will never see the benifit of running higher
octane/RON rated petrol.
It probably makes a difference on the track, but even then only small.

jusy my 2 cent worth

 

I put in 85.65 litres in the week, all the bars on the guage were lit and the fuel logo had been flasjing for about 15 miles, so if the guage starts to flash at 15 litres as it should - 15 or so miles plus the 85 odd litres you get your 95, so mine seems fine. i do however drip feed it after the first click.
