Anyone who knows of any locations which sell high octane unleaded gasoline in the DC area (anything over 94 octane)?

Please post any locations here -- even if the location is at a race track or drag strip, it would be helpful. Also if you know the information, include octane rating and price per gallon...

 

been to MIR, they sell 100 octane... forgot the price though.... what? Sunoco 94 isnt enough?

Thanks for the pointer on MIR.

Sunoco 94 is better than 93. I don't think I need more than that on a regular basis, but I'd like to try a tank of the racing fuel just to see if it makes a difference.

 

You might try Old Dominion Speedway too, they run drags on friday nights and circle track on saturday nights. It's near Manassas of 234.

 

I'll have to check out Old Dominion Speedway. Funny I never knew that was there, considering I live only 15 miles from there.

I did find this link...

According to their listings of retail outlets selling Sunoco 100, the closest to DC seems to be Catonsville Sunoco in the Baltimore suburbs, at 6324 Baltimore National Pike (Route 40). This is about a mile west of the Baltimore Beltway (I-695) on Route 40. No price is shown, but a little web searching shows that 100 octane unleaded seems to sell in the general vicinity of $4 per gallon.

I will check it out when I get a chance, but it's a little out of my normal range, so it might be a few weeks -- anyone want to do a little scouting mission?

 

i know where that catonsville sunoco is

 

theres a sunoco in Towson, on the intersection of Loch Raven Blvd and Taylor Ave(I think thats what its called ) Almost $4 a gallon!

 

the catonsville sunoco i have bought 100 ocate there before and yes it was expensive i put in half a tank before some racing i don't think it help so..

 

JBrennen - I ran a tank of 104 VP Unleaded before when I did a day of serious driving. Unless you have a boost controller, there won't be huge differences on the butt dyno. The thing I noticed most was how smooth the powerband felt - no jerkiness, surge, etc. Just really smooth up through the gears. The Evo loves the high-octane stuff. To answer your other question about where to find it, I have no idea, buddy. I'm just as curious as you are. Thanks for coming out yesterday!

Nastea - check your PM

 

Since that original post, I did fill up with Sunoco 100 octane at Summit Point. My butt dyno didn't really notice a difference until my next fill-up, which was with Exxon 93. Leaving the gas station, the car felt hesitant, much like it does immediately after a cold start. Best I can figure, the ECU had "adapted" to the 100 octane stuff and probably either advanced the spark or tweaked the A/F mixture -- then when I went back to 93 octane, it detected detonation and dropped back to a "safe" map.

I realize that getting full benefit of 100 octane requires aftermarket engine management, but I still think that running the 100 octane with the stock ECU probably helps a little bit. The car had the 100 octane good stuff in it at the 10/19 autocross, when Brian Burdette won ESP in my car by 0.036 seconds. I am pretty sure that the difference between 94 octane and 100 octane on an autocross course could easily add up to 0.036 seconds over a 50-second autocross course. In this case, the difference between 1st and 2nd.

I plan to do some divisional or national level autocross events next year, and I will make every effort to fuel the car with 100 octane fuel for those events.

 

You can also buy 104 and 115 by the can from them.

 

Powerhouse on Lee highway, sells CAM2 purple to Alcohol.....which is leaded but smells sweet.......if you need unleaded go to Calhoun Speed on Duke street...hope this helps
