Hi, any advantage to using octane booster for an engine with only an 8.6 compression? Highest grade I can buy at local pumps is 91. Thanks :-?

If you mean the stuff you add at the pump you won't see a whole lot of boost, probably not anything noticeable at least.

I agree with Andrew, forget the additives. Buy the best gas you can and if you have problems take it to a mechanic and he can tune the car for the gas you are using.

You will not notice any performance gains from a bottle of snake oil you put in your gas. If the car is knocking, don't go to the snake oil, go to a mechanic.

As others here said, don't bother. On a lateral note, i DO suggest using Chevron Techron gas additive to clean injectors about every 10k miles depending on your driving habits/usage. This helps keep the injectors clean. Of course the occasional 'Italian Tune Up' is a good idea too.

Italian Tune Up = after car engine/oil/water is warmed up, drive in a lower gear (to adhere to legal speed limits) yet have RPM at about 6.5k rpm for about 30 seconds.

Sounds cool. BTW not being Italian, would I have to pay someone somekind of commission to do the 'Tune Up' myself?? LOL :lol:

Fuel in France.

Hi ! So let me present myself for this first message… I am a new owner of a Mondial 8 QV white Cabriolet from 1985 and I live in Le Mans France (I am actually back from the Bugatti track where pre-qualifications started for the 24hours race in 2 weeks… Wahouuu…).
Concerning fuel we use 98 Super without lead here and I am putting some additive in since the lead was useful and had to be replaced on the fuel. I am surprised you run with 91, here the lower fuel you can get at the pump is 95.
I am searching for contacts with owners of the same car and would be very interested in technical advices since I am a new comer in the Ferrari world. My first day was already full of surprises, for instance I certainly filled up with too much cooling water and the car after my first stop throw away a litter or two of cooling water by the hose that goes from the top tap of the water vessel down to the ground close to the left rear wheel. I wonder if this is just because of extra coolant or if it could be due to over heating of the water and engine. Then how to be sure that I have no bubbles in this circuit now… Anyway I also had few lightening of the Engine coolant alarm that last for few seconds and stopped … then no problem during an hour on country side roads at reasonable speed… The cars also have an alarm on the air/conditioning panel when I start it but the former owner told me that the Freon gaz should be changes. I guess there is no link between those two alarms. You see I certainly have a lot to learn… but pleasure is already there…

Ciao ! heuuu…. Au revoir.

Shadoko, Suggest you contact 4kids3fish. He has a lot of experience with Mondials. On the coolant, if you overfill the expansion tank, it will drop the overfill on the road. Just make sure the system is now filled to the proper level and all air bubbles are bled out.

On petrol, US 91 is roughly the same as 98 in Europe.
