MYCROFT NOW YOUR STARTING TO TALK SOME REAL SENSABLE TALK Had to
happen eventually Manganese is essential for Optimax to work (see my paper of Oct. 2000, LSOC) I have found only traces of Toluene in Opt. for the most part it is Xylene and Benzene. Optimax is high (very high) in Iso-parafins. Any 'metal' (if its compound is 'soft') will assist the valves and to some extent the detonation. However some metals will cause the valves to rotate to quickly (performance road cars valves rotate at around ½RPM, saloon cars 1RPM) causing valve wear, this what caused all the trouble with Shells last foray into the hi-performance fuels, that had to be withdrawn as the claims against them were getting 'out of hand' I like what Optimax does, but I am always aware that their last effort screwed cars over a 2year period, I hate to feel like a long term test 'guinea-pig'. To some extent I feel that way about all the OBs'. |

I knew you would get it right
)I would have thought it wasnt exactly the speed of the valves rotating but just the lack of lubricant to protect them. We are finding here that the 98 is not as stable as the 96 octane fuel it lose's its light ends a lot quicker ?? As for the toluene and other additives added i guess it all depends on the quality of the crude that they start with ? __________________ When only the BEST will do!! |

OK, Forget all the crap. Millers octane boost, will take Optimax to 103 octane. 97 unleaded to 102 octane, and 95 unleaded to 100.2 octane. Does exactly what it says on the bottle. I also use Millers Synthetic 10/60W for the engine, and Millers CRX for the gearbox, and CRX LS for the diff. Leigh. |

I suggest you look again. I have the spec from Millers for the Octanne Boost here at my desk. Picked up from the Autosport show this year at the Millers stand. Leigh |

PHILLIP ,MYCROFT YOU ARE CORRECT
LEIGH TALKING ABOUT CRAP !! YOU ARE THE KING I WOULD SUGGEST THAT THE INFORMATION THAT YOUR READING GOES SOMETHING LIKE THIS ; ADDING THIS BOTTLE TO THE FUEL TANK WILL INCREASE THE OCTANE EFFECT BY UP TO 6 POINTS (SOME USE UNITS / NUMBERS)OR IT MAY READ INCREASE'S THE OCTANE EFFECT BY 5 TO 7 POINTS. SO WHAT YOU TELLING ME IS THAT THE "NITROUS fORMULA" RACE 6 RON WILL LIFT THE 98 UP TO 158 OCTANE GEZZZZZZZZZZ ID LIKE TO SEE THAT !!!!!!!!! BUT IT WILL LIFT 98 UP TO 101.5 IN 60 LITRES OF FUEL BUT ACTUALLY HAS AN OCTANE EFFECT OF AROUND 103/104 !!!!!!! OR IF YOUR TALKING COMPARISONS THEN A BOTTLE OF THE "NF" RACE IN 40 LITRES WORKS THE SAME AS "VP 112" OR "AVGAS 114" GIVES THE SAME 1/4 MILE TIMES 11.2 OR 666.4 BHP __________________ When only the BEST will do!! |

Millers
I have posted in another thread in general section titled
Super-unleaded..... Conclusion from weekend's driving was: Super-unleaded = no detonation in my car at either 1.25bar or 1.45bar Normal unleaded plus Millers = detonation at both settings (less detonation at 1.25bar) Unscientific conclusion, Millers does not uprate 95 Octane to 97 Octane, or even close. This is real empirical evidence, I can't comment on the theory as I'm not a chemist. Guy |

Hi all.....
....How to pass a whole evening: 1) Read this whole thread 2) Read it again 'cos most of it went over my head ......blummin' fascinating read folks, respect to Mycroft Holmes.. ..Back to the original debate of OBs....for those of us saddled with a paltry IQ of 145 or less..... a) higher octanes are better b) and hard to find in small bottles c) fuel loses octane whilst in storage ...these facts I have gleaned from the thread so far.... So, chemist dudes, what escapes from the fuel to lower it's octane, and can you bottle it and sell it???? Apologies for the overly simplistic post, Jon. __________________ Take care, JonB |

#what escapes from the fuel to lower it's octane, and can you bottle

Leigh, tested MIllers, get this, not even close. NF one shots now in, 3 RON increase. £3.49 Millers maybe cheaper but doesn't take NUL to 97 yet alone any other petrol. ![]() |
