    All my Ferrari's have used Tesco momentum always . (99 oct)
    on some occasions Shell V Power.
    Never any problems.
    33k on one and 45k on the current 430.
    My other 4 cars use Tesco as well.
    142k on one with not a single hiccup.
    I get a higher mpg than with Standard which justifies the extra cost
    Spider,or coupe? Just get one of each.

    I'd fill the tank, as you will minimise the opportunity for condensation to form, and thus introducing water to the fuel.

    Would also be worth looking at an additive re.the ethanol. I use one for my garden tools as they sit for long periods of time. Where I buy it from the mechanic said most of their work was de. gumming tools that had been at for long periods of time.

    Come spring, either drain the tank and refill with fresh or go for a long drive and get rid of it!!!

    The octane rating determines the temperature and pressure the fuel can withstand before self igniting. Generally turbocharged or high compression engines require higher octane petrol to prevent early ignition in the combustion chamber - ie before the piston is at the correct point in the compression cycle and the spark plug fires.

    Early detonation can be detected by a knocking sound coming from the engine. It results in poor performance, higher temperatures and possible deposit build up in the cylinder - all of which can harm the engine over a sustained period.

    If filling with regular (95 in the UK) doesnít cause your engine to knock then most likely it wonít be doing any damage and youíll not be suffering any performance loss. I say most likely because early detonation can be difficult to detect sometimes and can be causing deposit build up without audible knocking.

    If you do run your Ferrari on regular then I would fill up with premium every 4th or 5th time just to ensure that any deposits that may be present are blown out before they can build up. Correct flame front and airflow in the combustion chamber should sort that.

    That said, using premium where it is not needed is just a waste and provides no benefit beyond the marketing hype.

    360 manual states the same, 95RON. And I am sure it actually states higher octanes are not required as the engine in tuned for 95.
    Audi TTS (2ltr Turbo) on the other hand stated 98RON. Did use 95 a lot as I thought it was a waste doing mostly motorway miles.
    458 havent actually checked the manual and so far have used both.

    430 manual says 95, 612 manual is in the glovebox in storage [emoji849]. Interesting. Iím going to fill with 95 and see if I notice a difference.

    Yes - 430 is 95. No point running them on anything more.

    I always just assumed it needed 98. Live and learn.

    Although would the DMS remap change that? Did Tony say anything about that to you Mark?

    I think there is a lot more to it than just RON ratings - additives for cleaning & protecting the engine for example?
