Sunoco 110 Octane Racing Gas ?

[billt460]

I was at one of the local gas stations here in town getting some propane yesterday, and they had Sunoco 110 Octane "Racing Gas" for $10.00 a gallon. I talked to the attendant about it, but he couldn't tell me much. Except they don't sell much of it. He said the dirt bike guys buy it, and the race boats in the Summer.

He didn't know anything else about it. Does all this stuff have to offer is the octane boost? That seems pretty steep for costing almost 3 times as much. I wonder if there is anything to be had running 2 stroke engines on it?

I remember years ago, (early 70's), Sunoco had the "Custom Blending Pump" that had all kinds of different grades. Up to Sunoco 260, which was supposed to be over 100 octane. But that was back in the days of leaded gas.

I wonder if this stuff is any different, (or better), than 100 LL Aviation gas? Other than it's most likely unleaded, with a tad more octane. I'm looking for an excuse to buy some, but I honestly can't think of a reason. Maybe air cooled generators running in very high temperatures under full load?

I think it is Ethanol Free!

 

[Chris142]

It's only double our price lol

 

[billt460]

I think it is Ethanol Free!

There is another station in town I buy 93 Octane Ethanol Free, for right around $4.00 a gallon. I use it in all of my gas powered generators and 2 stroke saws. They sell quite a bit of it.

Is there a race track, or a lot of car clubs around? The only ones buying that would be racers or the like.

It is leaded. How that works is beyond me?

According to their website:
https://www.sunocoracefuels.com/fue...co® Standard™ is,in many forms of motorsports.

It's a leaded fuel and can't be sold at regular stations. Non eth.

Prob unleaded but not sure, may be more stable that regular auto fuel and a higher vapor pressure than AVGAS.

Yes, both. There are A LOT of hot rods here, and a dirt track "speedway" that is in the same complex as the Sportsman Club.

I think somebody's getting ripped off.

It's sold right at the same pump island everything else is sold at..... BUT, I'm not sure of the nozzle size. If it is leaded, I'm guessing it has a larger nozzle that won't fit unleaded, late model fuel tanks.

What fuel does NASCAR use?

What fuel does NASCAR use?

High octane E15 is the current brew. Nascar is going green, or some such nonsense.

That would be Sunoco Standard 110. I have specs on it.

Leaded: Yes
RON: 114
MON: 106
(R+M)/2: 110

SpG: 0.731
RVP: 5.7 psi

IBP: 129°F
10%: 172°F
20%: 192°F
30%: 205°F
40%: 212°F
50%: 221°F
60%: 223°F
70%: 227°F
80%: 239°F
90%: 244°F
FBP: 259°F

AFR: 14.9
Ethanol: 0%
Oxygen: 0%
H:C ratio: 2.07
BTU: 18,700

This is a good fuel for engines that see a lot of heat. The lower range of distillation is rather high with 20% way up at 192°F. That means this fuel wants plenty of heat in the head(s) and chamber for initial vaporization. This can cause some issues with cold starting as a fuel can only combust if it's a vapor.

Boosted engines would like this fuel. Dirt track cars and any application that sees sustained WOT will like it. It wouldn't work well in a drag car running at low engine temp. Emissions systems would hate it. It's not remarkable in any aspects other than offering high octane. There's a Sunoco station about an hour from me that has this at the pump. Some guys, with engines built at the limit of what 93 pump gas can handle, will put 3-4 gallons of this in the tank and fill up the rest of the way with 93.

High octane E15 is the current brew. Nascar is going green, or some such nonsense.

The 15% ethanol also helps keep engine temps in check. Straight gasoline has a HoV of 9.7 BTU/lb of stoich air. E15 is 14.8 BTU/lb of stoich air, a +53% increase in intake air cooling.

 

[billt460]

This is the pump. It doesn't show the nozzle size, and I didn't look when I was there. (Old price $9.60 @ gallon).

It's leaded gas. Off road use only.

 

[MRC01]

You can buy avgas, 100 octane low-lead, for a lot less than that. It also has no ethanol. Long storage life and very low vapor pressure.

 

[tnt_motorsports]

Our local VP sells 110 at the pump that’s leaded. It’s for off road use only. I suspect many of the local racers use it for dirt and drag racing.

Just my $0.02

100LL avgas suffers from the same problem as Sunoco Standard 110. In an NA automotive engine, at ground level, it can be sluggish in terms of throttle response. This is due to the initial boiling point and lower end of the distillation curve being rather high. Avgas has to have a higher boiling point to ensure the fuel doesn't evaporate at high altitude and cause vapor lock that stalls the engine mid-flight. They're not concerned about how the fuel performs at ground level. It's plenty adequate enough for planes that are rich at takeoff anyway. They care that the fuel is stable at 15,000 ft where air pressure is only about half that of sea level. It'll still run fine in a car engine at ground level, just throttle response will suffer some.

At VIR they have one of those old blending ones for show, it's super cool! The 110 stuff has lead in it also BTW, I've run the 100 before and logged to see if I was gaining anything, I wasn't for the ~$10/gal that I can't get with a few gallons of corn (E85 for 1/4 the price). My UOAs after tracking and using the race fuel have had small hits of Pb in them. I just bring 2 5 gal race cans of E85 which lasts me a weekend blending it down to E20-25 or so for knock resistance.
