Exactly,
People are confusing MON octane number with performance number. So Avgas 100/130 is a fuel with a MON octane rating of 100 or higher and with a performance number of 130 or higher as determined on the supercharged or F4 engine. I've had the 'pleasure'of testing many batches of Avgas on these engines..
cheers

Pelton, Fuller Take A Look At GAMI's G100UL
Cessna CEO Jack Pelton and AOPA President Craig Fuller flew into Ada, OK on Wednesday to get a look at a new 100LL replacement proposed by General Aviation Modifications Inc. As we've reported previously, GAMI's G100UL appears to perform similarly to 100LL and the company claims it's producible using conventional refining methods. GAMI invited Pelton and Fuller to Ada to view a detonation test cell run comparing G100UL to other fuels. In an evening e-mail to other GA leaders and the press, Pelton said "We participated in a thorough brief along with a test cell demonstration running three types of fuels, 100LL, min spec 100LL and G100UL. At the conditions we observed, it was very interesting to see the data on the engine characteristics for the three fuels. I would characterize the conditions as worst-case sea-level tests. In general terms, G100UL out-performed min spec 100LL and seemed to be about the same as straight-from-the-FBO 100LL." Pelton said in his view, G100UL "looks to be a fuel that can be refined and distributed within the existing infrastructure we have here in the states. I would guess it could be produced in many other international locations also."
Pelton added that "I know the devil is in the details. But this project is very interesting and very exciting. George [Braly] heard what the EPA said about 100LL is trying to do something about it for our industry." Pelton said he encouraged other GA leaders including GAMA's Pete Bunce to take a closer look at G100UL. The fuel is currently undergoing test in a Cirrus SR22 and GAMI has asked the FAA for an STC to move forward with wider fleet testing. It has also applied to ASTM for a formal fuel specifications approval.

Octane you seem to have a good insight into aus fuels; when was the shift from unregulated fuels? I refused to use anything other than BP after having to replace 2 fuel filters when some dodgy Shell (vpower F1 "100 octane") fowled up my cars fuel system (went from clean to black in 1 tank). I also had a similar issue with Optimax fouling plugs, going off after a week and causing large power loss and idle hunting. I was using Mobil for a while but moved away from it after I found it limited the power of one car with quite severe pinging. All solve as soon as I filled up with BP. Hence why I haven't used anything other than BP for the last 5 years.

What kind of car are you driving??
And where are you?
Having said that the BP Ultimate is the consistent preference of folk who have been fussy. I use the Caltex 98 in my bike....funny enough it hates AVGAS
. Runs terrible!

Bp 98 Ron and shell 98 Ron are the same product, coming out of the same pipe. The only difference is the logo on the side of the truck they go into before the get delivered to servos!

Have heard that also....mind you they may add different additive packs ....what about other locations? Its hard to know as they all cross supply around the country.
RatsoreA.....you wouldn't happen to work for a Shell refinery by any chance?

Any contamination is more likely to be occuring at the point of sale, the service station itself. Most bad fuel has been linked to a particular station having contaminated underground tanks. Although BP was the one who stuffed up the AVGAS additives at the refinery back in 2000.
Which refinery the fuel comes from depends on where you live and some times its the same product. However the additives may vary in the product, this can be the main difference in what is sold at the pump.

There are only 3 refiners of 98 Octane MOGAS in Australia. Shell, BP & Mobil. Everyone else buys from one of these or imports. Typical imported fuel is bought on the Singaporean spot market.
BP / Shell / Mobil may still do some fuel sharing (ie they swap fuel rather than having fuel trucks pass each other on interstate highways).
The BP Kwinana refinery is or was regarded as having the best process control of all Australian refineries.
Part of the wives tale of differences in brands I think dates back to the time before Australia had a National fuel standard (2004?) when there were different state based requirements and fuels differed widely. These days, I challenge anyone to pick the difference between BP/ Shell / Mobil 98 octane. The guy next door who builds race engines has a preferred fuel to get the most power on the dyne, but its not one of these and I suspect his results are due to the non-real world environment of the dyne room.

A question for Octane. Some years ago Peter Garrison's column in Flying magazine mentioned that the US was experimenting with fuel with a performance rating of 400 before jets overtook the turbo compound radials. Do you have any knowledge of this? Can you imagine the sight of a turbo compound radial at full noise on a dyne running these fuels?
Where it is allowed, competition vehicles run self oxygenating fuels (elf, Philips, etc). How does this impact on Octane rating? When I last used them (10 years ago) the cost topped out at about $15 / litre. I'd hate to think what it costs now.

Old Akro, I think you're reffering to what is known, in the industry, as C16 Race Fuel.
I purchased a 25 litre drum of this for a dyno run a while ago and it cost me $250, and that was at mates rates too. Wasn't by any means cheap but yet... it proved itself. Good Stuff C16 is, Unleaded, with a 130-140 octane rating. Most Bang for the buck you can get
