Yup!

 

I think you should correctly size the injectors to your application and not run on them maxed out in the first place. Then this isn't a problem. Epstein said it best. Gasoline is a great solvent and cleaner on its own. Any thing you add to it is just marketing.

 

Very good input.. I have a question..

How does ethanol come into play here? what about when they increase ethanol percentages in the future, will this dilution be a problem?

 

If you think you're going to keep gaseous Nitrogen inside a liquid, in an unsealed container, I've got some volcano insurance to sell you. Go open a Guiness and see how long it takes for the Nitrogen bubbles to escape. They're talking about nitrogen compounds related to the detergents. And those detergents are NOT inert. You're not changing the makeup of the fuel much with nitrogen enriched detergents versus the standard variety. Don't foget that we're talking about 5x the MINIMUM detergent level. How many detergents do you think the gas at Wal-Mart has.

Here's something you should write an article on: Why you shouldn't buy a direct injection car because all of these wonder cleaners won't brighten the backsides of your valves!

 

Gotta use Seafoam on that part I guess.

 

LOL wonder cleaners is right. Just as good as volcano insurance in florida LOL! I guess the only one i've heard that works worth while is seafoam treatments. Other than that, I think taking it apart is the best resolution. Until shell releases more info about this mystery gas, everyone is in the dark and will make their own guess. Most say its a scam, so until shell proves us wrong--- i'm not putting that stuff in my tank. I need more info about it first, not jumping in with both feet. Just too many unknowns to gamble with my engine, what about yours?

 

You must not put a lot of stock in your tuner if you won't put a publicly available Tier 1 93 octane fuel in your car. I mean, come on... the 02 WRX is a time bomb but don't you think you're being a little over cautious? Is that thing still on it's first engine?

 

Racetrack, Chevron, or 7-11. Either Sunoco or Shell has this bad thing that comes around every year or so, they get a bunch of sulphur in thier gas, which causes corrosion in GM fuel gauge sending units, causing false reading and resulting in the need to replace the sending unit. Since both my cars are GM, I avoid those stations like the plague.

Hess in my area tends to be among the most expensive, cant say Ive ever tried BP, the one closest to me shut down a while back.

 

From my understanding ethanol makes less power per unit than regular gasoline. So that means all these stations using the 10% ethanol blend, are selling you less potent fuel. 10% ethanol would mean that fuel potentially makes 10% less hp than an equal amount of regualr gasoline.

How does this effect you? Well that depends...in a car like mine, that is by no means optimized, it doesnt effect much. In a more sensitive car, say a 350z, or a well tuned car, this could be a big difference.

IE: Sport Compact car magazine tested a 350z (bone stock) with 93 octane fuel, then again with 100 octane...they gained something like 7hp with the 100. They said with the 93 it was visiting the knock sensor a lot. Thats what inspired the 100 octane test. So you figure, with the 10% ethanol 93, that same car could potentially show hp below stock levels.

Unfortunately I think the 10% blend is FL law now. Bad news for anyone trying to really max out their car.

 

so if its required by law what would you do to fix the octane issue? octane booster? will race gas fall under the law as well?
