    What type (87, 91, 93 octane) is best for the Mondial engine? What brand is best? Do you use any fuel additives? I searched old threads and did not see much on this. I have a 87 QV.

    If a US version 1987 Mondial 3.2, see page 20 of your 397/85 OM. Ferrari recommends using a 95 R.O.N. minimum octane rated fuel (which is about equivalent to a 90 A.K.I. minimum octane rated fuel in the US -- as US gas pumps show the fuel octane rating in A.K.I. units, not R.O.N. units).

    The way things are going you may be making fuel from pig poo yet. I bet the exhaust tone is nice

    I use non-ethanol gas. Expensive but helps my fuel distributor not clog up

    Fun fact: all gasoline brands tend to share the same distribution farms. Chevron pipes in 10K gallons of gasoline into a farm and then is allows to truck out 10K gallons. Ditto with Shell and every other refinery. When a truck delivers gas to shell vs chevron, for example, they pour a ~gallon of additive into a ~10,000 gallon tank. A delivery to a gas station that buys on the spot market won't neccesarily get the additive package.

    For your needs, I'd say the octane rating matters more than the additives with E0 vs E10 gasoline being a secondary concern. fuel additives, with the possible exception of stabil for long term storage, I think would have minor value for a mondial.

    One of the biggest claims of fuel injection cleaner is that it helps with your classic fuel injectors (i.e. to make sure their spray pattern stays good and unclogged); Im not sure how important that is with the more primitive fuel distribution setup that these cars have. If you really want to burn money (literally, since the stuff goes up in smoke), you can always fill up with any brand gasoline and then every so often run a can of fuel injector cleaner (ex: Chevron Techron) before a gas change (so you know that any amount that makes it from your gasoline to your oil will be drained shortly. IIRC, that stuff when used in a tank of gas is claimed to be 10x more concentrated than the techron that is premixed with Chevron gasoline.

    In Ontario, Canada, I use the only gas that has no alcohol, and that is Shell V Power. It has higher octane than necessary, but avoiding the alcohol is a good idea.

    I also run a small amount of Red Line water remover at the beginning of each season, don't want the nice aluminum fuel tanks or the fuel guage sensor to corrode, and alcohol fuels are a magnet for moisture retention.

    My gas tank hoses, including the key tank connector hose, were replaced with the Scuderia Rampante hoses. But not everyone will have these hoses that can withstand the alcohol enriched fuels. A newly rebuilt fuel distributor has better internals that can withstand the alcohols. But who knows how the rubber in eg. an accumulator, or the pressure regulator do with the alcohols, so best to stay away if your local stations have pure gas choices.

    The Ferrari engines are not that high compression, and the ignition controls are effective, so the car would probably be ok even on regular gas, 87 Octane in Canada. But mid grade 89 or premium 91 with no alcohol, would seem to be the choice the cars were designed for.

    Fully DISagree to that !
    E10 is a killer for older cars like ours (and might be one of the intentions for making it mandatory stock at the pump).
    Whilst true engine damages might only show after 20.000km or so, the rubber hoses will show deterioration after sometimes less than 3 years.
    I had to swap all fuellines - albeit the steelflex type - on a 1.6 rabbit/Golf for the owner having reluctantly continued to fuel up with 95 octane without caring for the E10 indication. Fuel just squirted out of the hoses.
    Same age car that requires 98 octanes, that still is being sold as E0 or max E5 in most EU countries, has no problem with the hoses.

    I always use Shell or Mobil. High Test as my Grandfather used to say.
    I wish we had ethanol free but we don’t.
    I use a bottle of Techron in weeks leading up to my pre-winter oil change and put her away with some stabil.
    Seems to work.

    Thank you to everyone! My 87 is a USA model. It is my first Ferrari, so I want to treat it right. It makes sense to use some redline to keep the water out, especially if it sits so long during the winter. It is very difficult to deal with alcohol in our fuels and ethanol will not be going away anytime soon, so we must deal with it. I am mainly concerned with my fuel distributor being damaged.

    One thing to consider: review the ingredients of your fuel stabilizers for when you put your car away for the winter... esp if you are putting stuff in the fuel for water removal. If you want to avoid alcohol, the stabilizer you choose might have the opposite effect.

    HEET specifically is marketed as a water remover and is mainly isopropyl alcohol.
    STABIL is petroleum distillates but claims to be alcohol free.

    They also make "ethanol treatment" additives. I know nothing about this stuff so it would be an interesting thing to research to see if any are worth it or if its all just snake oil (repackaged detergents).

    Shell V Power + Techron additive.

    Probably not a daily driver, so the fuel date should be noted. Old fuel should be dumped. Fuel filter replaced annually.

    The K-Jet fuel system must be kept clean, or you will have rough running problems.

    Seems to be some internet chatter than ethanol free gas may no longer sold in Ontario as of 2022. Possible, but otherwise Shell V Power Nitro previously had no ethanol. Some Canadian Tire and Costco in Ontario premium also had no ethanol.

    This site has been accurate in the past, and one could call the station and confirm directly

    What about starting your mondial at least once every two weeks in storage during the winter? That will keep the engine fluids fresh and maybe eliminate some of the water retention inside the engine.

    Unfortunately you need to run a car under load for a while in order to get the temperatures need to boil off water than infuses naturally into oil when left to sit. If you have a coolant and oil temp guage, you can see the coolant will heat up fairly quickly, but the oil temp climbs very very slowly. Starting up and idling wiill have the opposite effect to what you would weant, you will heat things up but not enough to boil off water, but when you shut down the temperature change will attract condensation. This is why short city trips are so hard on a car.

    93 octane. Only put as much gas in the car as I will use that drive approximately. With winter weather and other distractions I don’t want the gas to age.
