Earlier today while driving out East on Long Island I stopped to fill my tank with gas, and at the station, all the pumps had the usual Regular, Mid, Premium on one pump, but on the 2nd pump which typically holds Diesel, there was a sticker for Racing Fuel.
The button for the fuel indicated a 100 Octane level, whereas the Premium was 93. Now although I've seen Sunoco do 95 Octane for maybe a dime more than the Premium fuel, the "Racing Fuel" at this station (LukOil) was $8.99 a gallon!
At first I thought someone messed up the signage as a joke, but after putting my card in the pump to pay, the prices lit up and the 100 octane had $8.99 as the price. This also was the same at the other pumps, and on the major road sign when pulling out.
All the other fuels were from $3.65 to I think $3.90.
After seeing this, my main question isn't to ask about Premium vs. Regular octane levels, but rather I'm curious about if such fuel is safe to use in your typical stock engine on a passenger car, and in addition whether this "Racing Fuel" has anything more than extra octane because I know Sunono Super Premium is typically 10-20 cents higher than premium.
Also, is this a new major line of fuel that's going mainstream? I've only seen this once at the chain -- every other LukOil carries Diesel instead, so I'm not sure if this might be a regional offering.
