Motorsport 103,
will support up to 12.5:1 compression, has a 3 - 8% power gain over Av Gas, is rated at 107.5 Ron (octane) and has a spec gravity of .743, similar to pump gas. VP Fuels mentioned to me about government regulation to lower PULP octane to 89 - 91 by 2005. The web site he said it was on is
http://www.ea.gov.au but I couldn't find anything about it, maybe you guys might have better luck. He says Motorsport 103 was used at the Summernats in Horsepower Heroes recently. Maybe this is getting off the track a bit, the original question asked was Synergy or Optimax and we have already established the answer as neither, that BP Ultimate is the best. The suggestion is, Ultimate is straight from the pump @ 98, the others are blended with differrent %'s of Ethanol etc, to get their octane rating.
ELF 124, it is purely Racing Fuel and not street legal as best as I can find out at present. Get caught with it in your car on the street and cop the fine, $110,000.00 for the user and $500,000.00 to the supplier. ELF 124 is about $8/l.
Motorsport 103 is street legal.
The testing was to analyse the Density, Benzine content, Sulphur content, Distillation, Driveability index, Copper Corrosion, Final Boiling Point etc. Will give some idea and compare to regular ULP.
MY OCTANE TESTS:
BP Ultimate 98 Tested at 98.8
Mobil Synergy 8000 Tested at 98.5
Shell Optimax Tested at 98.3
Both BP and Mobil have less than 0.4% Benzine and Sulphur content and falls well below the max driveability index and Shell has over 3.0% and exceeds the max allowable index and if it stays as is will be illegal when the driveability index is legislated later this year.
Results: (short form)
SHELL OPTIMAX
Under it's present formulation, it will not pass the drivability index set down by the EPA for fossil fuels, that will become law sometime in 2003 (1 July) at a guess and therefore will be illegal to sell. Also, it contains over 4% Benzine & Sulphur and tested at 98.3 octane (RON). So if you want to breath all of this poop go for it, we will all come and visit you in La La Land.
For Optimax to meet the drivability index, the company must spend MULTI MEGA MILLIONS of DOLLARS on their refinery to allow them to crack LOW SULPHUR crude oils.
MOBIL SYNERGY 8000
Contains less than 0.4% Benzine & Sulphur, tested at 98.5 octane (RON) and complies with the drivability index NOW!! as is. A much cleaner, more environmentally friendly fossil fuel.
BP ULTIMATE
Contains similar quantities of Benzine & Sulphur to Mobil and tested at 98.8 octane (RON) and also complies.
GETS MY VOTE as NUMBER1.
"G" EVOLUTION
After some lengthy discussion and research, this fuel from Traffigura compares favourably with both BP Ultimate & MOBIL Synergy 8000 in all aspects. What you must decide is this, Evolution is not manufacture here, it is produced in Singapore and transported here via tanker and stored in Melbourne.
