I could care less about what detergent they use, I have performance car that needed gasoline that can help me get the full potential without putting it in danger. Most NA won't see the difference since most dont do any logging on their cars. Utec does detect knock (Maybe not the most sophisticated way) and my logs says Mobile/Exon suck!!! I want the highest Octane gas and less water mix in my gas coz that will lead to detonation. To bad Sunoco removed their 94 octane in NE (At least NJ and NY)
This is the main reason I got a Water/Meth Kit, it is much cheaper than running race gas all the time.

i use bp, the biggest reason for this it is the only station arround me that still has separate hoses/nozzels for all 3 octane ratings. i figure if the person before me used anything other than 93, when i press the 93 there is still a bunch of 87 or 89 octane still in the hose. in NJ there is usually 1 hose for 87-91 and a seperate for 93. what do you guys think b/c i reall dont know how it works haha

Hmmm never really payed attention to that. Most newer station use one pump now so I'm pretty sure or hope they did something about it. Either way, I usually put gas 10Gal or more so if someone did use a regular gas before me then that is going to be a small amount. There is a formula to find out how much octane you get if you mix two different octane gas.
Let say I used 1 gal of 87 octane gas and 12 gal of 93 octane gas.
1 and 12 is a total of 13. 1/12=8.3% 83 octane gas and the rest (91.7% 93octane). So, here is how you calculate it: [(8.3x87)+(91.7x93)]x100=92.502 or about 92.6 octane. Using this calculation, you only went down by .4 octane and this is if you actually put 1 Gal of 87 and mix it with 12 gal of 93. The number should be lower since you still have some 93 octane gas in your tank.

Have noticed Shell varies, sometimes good, sometimes sluggish. My opinion is it's either water or ethanol. I was curious, so I checked the manual, said 91 Octane and no more than 5% ethanol. Hess down here says no more than 10% ethanol, right on the pump. Anyone know what gas stations don't use ethanol? Or do they all put ethanol in their gas?

Did some research and at least in S FL, they are starting E10, but only a few stations carry it. Hess for one and they had this big sign on the pump "Not more than 10% Ethanol". Tried Texaco this go around and works well. Guess it's hit and miss.

The only guy that know for sure is the computer technican at the refinery who constantly monitors the composition stream into the holding tanks to maintain within limits. This stream gets eventually fed into pipelines where it pumps its way to your local terminal in small batches. Ocasssionally some is sampled and bulk chemicals added to fix it up if it has sat too long before shipment.
These small batches are mixed with other batches until the local terminal tanks are full of various different refineries outputs............why it's called fungible gasoline.
At the service station each refill will be slightly different day to day especially week to week depending on local turn over and wich refinery was doing what that week.
It can take 2 weeks from Texas to Washington via pipeline because it does not just go straight thru but gets diverted thru dozens of cities terminals pump stations along the way and can get sidelined and suffer for priority shipments.
Actually the only thing constant is the few drops of Marketing Additive added as the tank truck is filling up at the rack...........unless they run out of the cake coloring and have to borrow from another brand or just skip it until the rail tanker arrives tommorrow.
