I went to this Conoco station yesterday and added enough of their "Race Gas" to bring my octane up to 94. But, I was dissappointed that it cost $4.70 per gallon, so I doubt that I'll be doing this on a regular basis. I'm afraid my STi is just going to have to get used to 91 octane. I've heard that at this altitude gas acts like it has a higher octane than it does at sea level, so perhaps it's as if we were using 93 octane at sea level. :-?rwroth said:There is a station (Conoco I believe) at C-470 and Santa Fe that sells 100 octane. I do not know the cost.
Paid $2.02/gal yesterday. Been filling up there since I got the AP so I can run the 93 map.OA5599 said:93.5 premium at Petro Stop -
S Parker Road & E Quincy Ave , on the west side of the road.
They've carried it for years to fuel up the speedboats using the Cherry Creek Reservoir a 1/4 mile north of the station.
As you fill up , its like a muscle car show there ... every make - every year of performance cars waiting to get their share .
and its the same price as 91 octane anywhere else. 8)
