I'm going to get flamed for this with all the LPG enthusiats out there but the record needs to be set straight.
Straight from this site, the minimum typical octane rating of Shell LPG is 92. Straight from this site, the typical octane rating of Optimax is 98.4 Both octane numbers were reached using the same test. That does not mean that LPG CAN'T have a higher octane number than Optimax, but you can only RELY on it having a RON of 92. If you want to argue, do it with Shell. I'm tired of hearing claims that LPG has a RON of up to 130. I'm tired of hearing that LPG consistantly has a higher RON than a premium unleaded fuel. The facts are there in plain english. If you still want to believe that LPG has a RON of 100 and is consistantly higher than Optimax, go for it... but I dare say that the chemical engineers @ Shell will dismiss any claims you have. |

Hmmmm, that raises a good point.
I've always been told the octane rating of over 100, but never checked it out. Just checked BP and they've got 93 http://www.bp.com.au/products/lpg/lpg_product_info.asp can't seem to find mobils, but I'd think if they were any higher they wouldn't keep quite about it. |

LPG is a mix of propane and butane, butanes octane rating is ~91 and propanes exceeds 100 octane, the end product depends on the mix.

also, you do realise RON = research octane number.
of which BP states 100 for LPG and 95 for premium unleaded.

remeber to that shell want to make money and if they were to print real results of lpg and its octane beeing higher than its new 100 octaine fule, what do u think people are going to think, thats right s**t i might go to lpg.
Shell want to promote there more expensive fuel, they can put any figures they want on there website as will all petrol compaines. |

OK, i dont trust an oil company as far as i can throw it - but even this is going a little too far in the world of conspiracies. Im sure shell do very well out of LPG sales... i mean, people are paying up to 60c/L for what is essentially a by-product of the oil mining and refining...

Shell want to promote there more expensive fuel, they can put any figures they want on there website as will all petrol compaines. As 4.9 EF Futura said, LPG is a by product of the distillation process. For many, many, many years, the petrol companies simply burnt off the LPG. It is essentially a "free" fuel from the perspective of the fuel companies. It costs nothing to make because all the production costs are shared by the other fuels. Ergo, there is a higher profit margin on LPG. Now, it's a pretty damn decent conspiracy theory to say that Shell are pushing a low margin product over a high margin product. |

http://www.bp.com.au/products/LPG/lpg_product_info.asp states that LPG RON is 100
it states MON is 93 isnt that enough evidence to contradict what you stated originally?

It's Bp's word again Shell's. However, I will freely admit that I did not know that there was a RON and a MON. Having admitted that, I looked at Shell's info again and they state a MON of 92 for LPG. I initially posted a RON of 92 for LPG. Shell also simply states that the octane number for Optimax is 98.4. They do not indicate if it is RON or MON. However, it is tested using the same test that they used to test the MON of LPG so one can only assume that means Optimax has a MON of 98.4 I would assume that to arrive @ a RON rating would use a different test to arriving @ a MON rating. If it does not use a different test, then RON and MON are exactally the same. Ergo, if there's a difference between RON and MON, the testing procedure MUST be different. Shell use ASTM D2699 to test the octane of both LPG and Optimax. |

don't make so many assumptions.
MON and RON are actually 2 completely different things, deteremined by the same test. i'll bet my car on the fact that optimax has NOT got a rating of 98 MON. LPG has a higher octane then optimax, you will however hear the optimax rating described as RON. if you wanna further argue it (you WILL loose) then please continue with the assumptions that are clearly wrong.

again, BP states "PREMIUM UNLEADED" which we all know to have a RON or of 95. therefore comparing a RON of premo unleaded (95) to a RON of LPG (100) if optimax was to have a MON of 98.4 as you assume, the RON would be somewhere around 106. which it DEFFINATELY isnt.

"The Research Octane Number (RON, or F1) simulates fuel performance under low severity engine operation. The Motor Octane Number (MON, or F2) simulates more severe operation that might be incurred at high speed or high load"
