OCTANE BOOSTERS??
Anyone have any knowledge on using higher Octane fuel or fuel boosters?.
In the UK our standard unleaded fuel is 91 but the manual does say for best performance use 93 , which we call super unleaded here.
BP and Shell claim to use performance boosting properties in their premium fuel but don't state the Octane level. I tried the BP Ultimate Fuel, couldn't perceive any difference but it is a bit tricky to judge as I,m still running her in.

If your engine isn't "Pinging" or have pre-ignition (running after you shot the key off, you should be okay. I don't know if you have "104 Octane Plus" octane booster available in the UK. But if you do it really works very well. I used it in a Pro Street Mustang I had a few years ago. It had 11:1 compression and ran great with the 104 Octane Plus additive.

I have been wondering about that a bit here, in the States.
You can't aways find 93. In Northern Michigan last week I had to go, litterally, three towns over before I found someone with 93 (about 30 miles). Everyone else was 92, as their top octane (Quite a few in Iniana are that way too). Luckily I wasn't in dire need at the time.
I am afraid of being stuck out in BFE without the gas to hunt and peck for decent octane, and forced to put 92 into an empty tank.
Been thinking of keeping a small bottle in the glove box for just such emergencies.

PS:
BP's Ultimate is 93, in the States, at least. (Used to be Amaco, best franchise fuel I've found) Haven't really noticed a difference with the Crossfire, but the Trans-Am used to run noticably better with it, over any other brand.

Do all these numbers make a difference or are you all being picky (no offence intended). Does a lower level damage the engine?
TAKEN FROM SHELLS WEBSITE:
What is the Octane level of Shell Optimax?
Shell Optimax has the highest octane specification of any petrol in the UK. It is greater than 98 Research Octane Number (RON)

It is all about timing!
More octane fuel burns not so fast, but when it burns it gives a bigger BANG. Correct me if I'm wrong.
I think this has no bad influence on the engine aslong that the SPARK timing is right.

Call around to some motorcycle shops in your area. People who road race motorcycles run hi octane fuel 108 and above.
I used to run 116 octane leaded fuel in my turbocharged eclipse on the road courses.
Higher octane fuel burns slower, with the proper tuning you can get major gains from this.
Anything over 112 is typically leaded (ask first). You do not want to run this in your car unless you plan on replacing your o2 sensors every year and have no CAT (emissions) converter.
108 unleaded or lower should be fine for your situation.
Fuel addatives are weak and only raise fuel octane levels a point at most. Adding more won't change much. You are only wasting your money. If you can find a race fuel shop, get a 5 gallon jug from them and have them fill it up with the highest octane rating you can get in an unleaded form. Add a gallon to a tank of gas and this will increase your octane rating by more than just a few points. Once it mixes of course.
--------------------
Our cars have an ecu which can detect the octane level. If you are running under 93 octane it will retard timing slightly to limit performance to keep from damaging the motor. It does this all on its own. Adding aftermarket ecu modifications however might have some ill effects.
When I ran this kind of fuel in my turbocharged eclipse, I had electronic fuel control to make the necessary adjustments to the computer. This way I could take advantage of the higher octane ratings and run more boost.

Octane Levels is all fine "BUT"
In the UK, if you use a higher octane fuel
than that bought in a fuel station "or Gas station"
then you can be in trouble with Insurance
as this is classified outside the normal and if an accident
accures and this is found, you will find UK insurance will
be void, Know of people who have been cought out on this before
in the UK.
