Thought I'd use the bottle of Wynns 'Race Formula' octane booster I had in the shed. They reckon it increases the octane rating by up to 5 points. Have adjusted the timing so it doesn't pink on 95, put 30 litres of 91 in with the Wynns, and it pinks under mild loud pedal. Obviously the 'booster' doesn't do it's job, I'll be going back to 95, as it's cheaper to use anyway. And. yes, I have seen the youtube story on the various brands.

Edited because I am pretty sure I was wrong there. From Wynn's site: 'Increases the Research Octane Number (RON) by 2 to 5 units.'

30L 91 RON @ $2.158 = $64.77 30L 95 RON @ $2.229 = $66.87
How much was that bottle of 'Race Formula"!

Well, that explains a lot! Just thought it was crap.

Was $14 at Surplus Direct.

Hang on, on another of their sites: 'Increases Octane Rating By Up To 8 Units'.!
Good read! Of course, it's cheaper to use the correct fuel instead of buying cheap. and adding expensive additives. So many new, or near new, car owners are cheapskates, I hear so many pinking it's not funny. The difference between 91 and 95 in my 73 litre tank is only around $5.

The octane booster producers don't make it very straight forward when it comes to their claims.confuses me a little anyway (the units and points part.)

go fill up with BP ultimate 98 .

Use either Gull Force 10, or add 10% ethanol to any brand of 91. Replace your resistor plugs with non-resistors (preferably multi earth.) You will notice smoother running and performance gains.

Remember though, that Gull and/or BP Ultimate fuels may not be available where the OP lives.

And of course, fuels with ethanol are not suitable for running in all types of vehicle. I for one, have no idea what the OP drives.

sorry but what exactly are resistor plugs!

I wondered the same

Resistor plugs have a resistor built into the central electrode. Ifthe letter 'R' appears in the middle of the plug part number, it is a resistor plug.This supposedly reduces RFI or EMI but it also reduces the amount of current available for forming the spark meaning less complete combustion and reduced performance. The unburnt fuel then passes into the exhaust system where it is burnt by the catalytic converter. The truth from my observations, is that non resistor plugs produce no RFI, because the plugs are well shielded by the engine block and cylinder head - no RFI can escape. If RFI is such a problem, why are petrol engines in aircraft and boats alway required to run non resistor plugs! These applications often have sophisticated computerised fuel management systems yet RFI is never a problem. Serious race motors never use resistor plugs.

I disagree. Tell the Brazillians.

Tried that a few years ago in Tauranga. 12c/ltr dearer than 95, didn't notice any difference in power, economy of general running. on a 400km trip, or the weeks running around town after I got home.

They are here in Whangarei, but my old engine won't benefit from it at the moment. However. I am about to fit a new, angrier 202 so higher octane juice will probly be required.

octane booster is not a substitute for proper octane fuel, it also eats away at the electrodes of your spark plugs.
