Octane booster

[adhawkins]

Anyone comment on the legality of CVL and CVL Turbo?

I was considering using it (after a recommendation from the engine builder) but obviously won't if it's questionable for Sprinting...

Optimax is available as a "pumped" fuel   and just fine  

and CVL is allowable as it is a valve lube or something or other .......... but octane booster isn't

Which bit did you miss        

[adhawkins]

Ok, so CVL is Ok, cos it's called a 'Competition Valve Lubricant', despite the fact that it also boosts octane.

However, CVL Turbo is called an 'Octane Booster' so isn't allowed?

Its simple - check the Blue Book

[adhawkins]

Yeah, I plan on doing just that. Wondered if anyone 'knew' though.

I'll try again......... CVL is fine   Octane Booster is not    

That applies to anything labelled as Octane Booster        

see not a   in sight

There's plenty of "pump" fuels out there that have high octane

Av gas comes out of a pump  

On a more serious note Mark this is available from your local airport at approx 145 ron (or whatever its rated in)

If you speak to the right man you can get your hands on the litres and litres of stuff they run of for tests and samples  

A mate of mine mixes this with standard unleaded for use in his extremely modified turbo and it works out a lot cheaper than super unleaded + additives

Ok, just to get this clear in my head, I checked the blue book. In section 'P' under 'Pump Fuel' it says:

Only additives to this Motor Gasoline Fuel solely for the purpose of lead replacement are allowed.

CVL is described on Miller's web site as

high technology fuel treatment for adding to petrol to improve performance and provide protection for engines operating in highly stressed conditions.

Valve seat lubricant and combustion enhancer based on advanced manganese chemistry

No mention of lead replacement there.

I'm not being (deliberately) pedantic about this, I just want to understand what is and isn't allowed (and yes, Mr. Chairman sir, I know you've said CVL is allowed, I just want to understand how it gets past the barring of all additives that aren't for lead replacement purposes).

I'd hate to use this at an event and fall foul of the regulations through not fully understanding them.

But Andy, isn't that a pretty good description of what lead did? So it would follow that it's just mimicking the lead. i.e. lead replacement.    

Quote from some DTI site or other:

Lead in petrol did two things. Firstly it increased the fuel's octane rating making it less prone to 'knock' or 'pinking'.... Secondly it protected the engine's exhaust valve seats from wear.

But Andy, isn't that a pretty good description of what lead did?

I don't know, that's why I was asking

Just trying to understand how CVL fits in with the regulations. If it does, then fine, but as I said I'd hate to fall foul at an event...

If in doubt dont use it

If you are sure then use it and prove it

Avgas eh - lucky the girlfriend is a pilot  

[adhawkins]

Bit more, I took a look at a bottle at lunchtime.

It specifically says on the bottle that this is a lead replacement, but that it has the benefit of increased octane etc.

I presume this is why it's Ok?

if it has to be pumped fuel i can rig up a pump and a small fuel bowser of 100+ octaine fuel and pump as much as you all need .

or is that still cheating?

I buy my Millers products from Performance Oils who happen to sell what you are looking for at good prices. The more you buy, the cheaper it is as the carriage becomes more viable.
