I use 98 Octane unleaded 76 as my normal fuel. It works well and there are no probs. I notice less soot in my tail pipe now. Check at your race track or look for a wholesale distributor (not a gas station). I contacted Mitsu about the 98 ron listed in the operators manual, The 98 exceeds that requirment as it is research octane number plus motor octane divided by two. Using leaded fuel is a poor idea as it is harmful to your O2 sensor and your cat. Be sure to do enough runs to allow your ecu to "learn."

I get the 76 98 for $3 a gallon. So you can see the market here, the next most expensive is Chevron Supreme and that is currently at 2.07. The wholesale outfit I buy from does not raise the price on its specialty fuels when the local dealers' pump prices rise,It was still 3 when the Chevron was going for $2.40.

Running a few gallons of race gas at the drag strip a few times a year is going to have a very negligable effect on your O2 sensor, and I have never once heard of any DSM having injectors get clogged from it.
As for the cat...who drives with one of those anyway.

I've only used unleaded race gas or a xylene mixture so I can't speak from personal experience but my friend with a 99 GST used leaded race gas and his O2 sensor went out the next day.....

yeah come to think of it, he probably was running rich..... but I don't know about that rich because his ECU was still pulling timing... he was on a 14b setup running consistent 13.7s

How?The only detrimental effect of a race gas is pugging your cat...if you have one. Your O2 senosr will also loose it's sensitvity. Mine does after running race gas (leaded 110) but after I put regular gas and drive it, it's fine.
