Sorry I couldn't reply guys, the power was out and I shut everything off in case of emergencies. So everything went pretty well and fortunately I didn't have to chance it by putting regular in and I was able to catch a ride with my friend to exit 8A in Jersey (I believe its called Cranbury). They seemed pretty untouched by the storm and they had premium, didn't even have a line. So if anyone is still in search of gas that would be the perfect place its stress free and you don't have to worry about the gas running out. Also I've heard of people being able to snag premium of Pheiffer Blvd which is 5 minutes past the outerbridge but there is a line though if you have a gas canister the wait is only about 5 minutes.
And maybe I was driving the car a little longer than 5 minutes but when that thing goes to E that means its time for some gas haha. I've never been in a car as accurate as this so I wrongfully assumed that I had more than I did. And now the storms over I finally get to enjoy my car and now I can't wait to take a drive to get some gas! Hoping everyone else is well!! Good luck guys! Oh and if any of the forum members need help with anything do not hesitate to ask. |

I have a friend up in Rhinebeck. The storm missed the Hudson River Valley from Poughkeepsie to Albany, looping to the west and hooking back around as it approached Canada. Gas stations are plentiful...angry commuter lines are not.

I don't think it will be an issue. Wife filled up at least 3 times with 87 octane and haven't noticed anything out of ordinary.

It's easy to boost the octane rating. When they do gasoline blending they just mix in higher octane fuel with lesser until they get the correct antiknock number (ie. 91). Higher octane just means that the gasoline has more branched hydrocarbon molecules which burn more efficiently. It's all pretty much C7-C11 hydrocarbons though and blended with branched isomers to act more like pure iso-octane. These cars are now advanced enough to just re-adjust the air/fuel ratio to prevent any knocking (premature ignition due to unbranched molecules). I'm a chemical engineer who used to work at an oil refinery. Also, just to clear up one last misconception. All the fuel brands are the same, Chevron, 76, Connoco, etc, use the same gasoline from the same refineries. They just dump in their additives (special trade secret detergents) into the stream when they load up the gas into the tanker trucks. Hope this helps. |

If you're talking about gasoline, they all come from the same refineries. Chevron trucks can pull up to ExxonMobil refineries and vice versa.
The detergents, aka additives, they put in it are trade secrets for each company. The rumor is among the refiners though is that Chevron Techron is the best performing detergent. They all are pretty much the same though. I must say that they're pretty stingy on how much additive they actually put in which is why you should always just buy the fuel injector cleaner every once in awhile. |

I don't know why more people who work at refineries don't just talk about it. I mean we understand the whole process and business. Shouldn't be such a big mystery. |

But remember, law of diminishing returns. The closer you get to 100, you need to add more and more of the stuff. |

A lesson in chemistry and refining...
The alkylation unit using short chain hydrocarbons to produce longer chain branched hydrocarbons (stuff with like 100+ octane rating). The isomerization unit breaks down long chain hydrocarbons to produce shorter chain branched hydrocarbons (also stuff with 100+ octane rating). When you just distill the crude, you don't normally get a lot of good branched molecules that'll give you an high antiknock rating (mostly get straight chained hydrocarbons with nasty sulfur compounds), therefore, refineries gotta use really energy/chemically intensive processes to produce it (hence the premium price for the fuel). |

Don't worry, just a buncha mumbo jumbo.
I think the 87 is fine for the car in the short term. I did a quick calc, and you'd have to put in quite a bit of the octane booster to get to 91. Going from 87 to 91 u gotta put in over 3 gallons of 105 octane per tank. Heptane (Straight chain molecule) = 0 antiknock/preignition Iso-octane (Branched molecule) = 100 antiknock/preignition Hope you guys on the east coast get access to more gas. |

not sure how much it has to do with the turbos, BUT, it is not nice for your fuel pump to go below a quarter tank, the fuel pump is inside the tank and is liquid cooled, by what liquid? the gasoline! so as your gas runs low, the fuel pump becomes exposed and heats up, and as anything on a car, overheating is bad and it can fail.. rare I guess, but possible.

I try not to let it go below 1/8 tank now, and my N55 and N54 powered cars have been free from fuel pump issues so far. Obviously my sample size of one failed fuel pump is small, but it's true that these fuel pumps are lubricated and cooled by the fuel itself and emptying out the tank is not a great idea. |

It's weird, the Philadelphia area was exactly in the path of the storm and we have no lines and plenty of gas... Outside of the shore obviously, I don't see what could be different in NJ in terms of ability to deliver gas to stations.

I believe it has nothing to do with delivering gas to the stations. It is about stations not having power to pump to gas. At least that's what I heard.

North Jersey got nailed with the storm surge just as NYC did. It just doesn't get as much press coverage. |
