A word of warning!

Mobil 98 and some 91 is illegal to use in super bike and super sort.

So will gull. Anything with any ethanol is illegal as out is an oxygenator

so if l had a steam engine in my super bike l'm fine

As usual, NO it it not. When we receive results of the sample testing back, a decision will be made based on this information, and conveyed to all affected parties.

IF there is an issue requiring a change of rules, it WILL be made public at the earliest opportunity ..........

In fact it is in the rules and it's up to competitors to understand this.

You are only allowed 0.1% oxygenators in your fuel. Mobil 98 depending where you buy it has up to 10% and 91 has up to 3%

Makes sense, on the subject at PMCC they ran Motards in F3, I was the rides rep and was approached by F3 riders asking why this was allowed due to rule 4.6 of the superlite rules, only clip on bars allowed no motard style bars.

So I approached the officials. I was told by PMCC that this year Motards had been let into F3 by MNZ for the nats so they had. The rule book that OMCC had (dated Jan 2012) still had rule 4.6 in it. Budda do you know if this rule has been changed, currently the MNZ website still states rule 4.6 is in place.

Anyway, the querying riders were happy with the outcome, I asked that any motard guys competing in F3 keep their feet on their pegs while racing with us normal riding folk, and the rules to be checked before next round.

I had a look at the Mobil NZ website last week after hearing about dramas, their specs for fuel say nothing about ethanol. Bad luck for those using Mobil I guess aye.

Glad you got things sorted, Chappy, and hope you were happy with the outcome.

I actually didn't mind it - infact the F3 feild was way bigger because of it - 26 riders or something. Manfeild is probably not a bad track to mix the two but Taupo would probably be too different between the two riding styles.

The riders that came to me were happy with the outcome for the day

To the best of my (limited) knowledge Ethanol is not an oxygenator - it only has one oxy atom in the molecule which is liberated by burning. It is however a very good carrier for others...blends with nitro well...

Don't confuse octane number (anti knock properties) with the calorific value obtained whe it's burned. Ethanol gives only about 2/3 the calorific value of petrol when burned

If you guys are seriously after power, don't use ethanol blends....under E85 that is to say...

OXYGENATED FUELS:A fuel such as ethanol-blended gasoline that contains high oxygen content is called "oxygenated." Ethanol is an oxygenate, meaning that it adds oxygen to the fuel mixture. More oxygen helps the fuel burn more completely, thereby reducing the amount of harmful emissions from the tailpipe.

This is why i love racing in a NON MANZ sport anything goes in the tank....

Okay, I'll rephrase that...it's not a very good oxygenator....Lets see what the test results show as here may well be other oxygenators in some of the pump fuels too.

And Peter - if you have to revisit the fuel regs, as already discussed in person, the specs for Methanol don't match what is commercially available in NZ.....

The Mobil site does mention ethanol fuel's in the materaial data safety sheets here. http://www.msds.exxonmobil.com/psims/psims.aspx Do a search under NZ, and petrol. They do say that it is less than 10% ethanol, but that other oxygenators may in the fuel.

The only difference Mobil 98 makes to me is that it goes on the Mobil card.....

Any oxygenators are a no no
