Is it worth saving about $.50 per fill up by using regular instead of premium? Just wish the stations around here did not have the 10% ethanol fuel
Ok... so some of that info Hippy posted (which I know he copy pastes) is true... but alot of it is WAY exagerated.
Floating tank roofs in the big above ground tanks... yes they exist, but it is not about evaporation in the sense that the company looses products its about the fumes they give off. Each facility has a permit on such things by the EPA. It allows them to emit a certain amount of fumes and polution.. each floating gas tank has legs on the bottom at say 9ft or so... even if they suck down the tank to "land the roof" they are only allowed so many per year. Most have to do it to "turn over" their RVP in spring time.
Yes each product has a specific gravity, yes that gty changes with temps and then we (in the industry) correct that gty change to a API standard of 60 degrees. Then you have to calibrate the meters to that days product temps, pressures, and gty. That gives you a meter factor where you multiply the gross meter counts by the meter factor to get the net meter counts or corrected amount. On meters like mine, large pipeline meters they are done daily. On truck rack meters they are done quartly, and gas stations are done I believe bi-annual, which would correct for the opposite extremes. All thoguht my expertise ends at the semi truck hauling it away from one of my facilities.
Now if you want to get in brands of gas discussion I can go there...
Do you want to know how they create the different levels of octane?

SIICK!!!
Chris told me last night how they create the different levels of octane.....very interesting...:up:
Oh yea baby
Bye Bye:2thumbs:
Grades of refining???
If so why is Diesel higher than unleaded. In the 70’s it was 1/4of the cost of regular. Yes now it’s low sulfur but shit it’s still fuel not gasoline…….WTF?
Gas will know!!!

I use 93 Octane either Shell, Chevron or Sunoco. I NEVER use Citgo. I have a real problem buying the Venezualan gas for Hugo Chavez. He wants all Americans dead, so piss on him.
Down here in SW Florida, Sunoco Turbo-Blue is really hard to find and not usually worth the drive. I used in in Michigan all the time in my show/race car, but only a mix in the bikes.
I never use Mobil. I'll use it in my daily driver. I was told they have lots of detergents in their gas to clean fuel injectors and that will fowl plugs. Since everything I have is carb'd, I stay away from that brand for the toys.

Yes Gas it would be intersting to know about the different octane levels I guess this is somthing with the R&M method...Dave.
There is no cliff notes... I'll copy out some explanation I gave a buddy in a email, so sorry for the forward arrows.
This explains a few things on generic gas vs branded gas sense Cobra talked about Mobil.
No understand in the time between that email and now... everybody here in michigan uses ethynol.
On the octane... allow me to show you how they create 1 gallong of prem 93 octane gas with ethynol, which is 113 octane alone.
Take the 10% of the 113 = 11.3
74% of 93 octane prem gas = 68.82
16% of 85 octane (sub grade) gas = 13.6
Add it all together and you get 93.72 octane gas.
Now if your gas station doesn't have ethynol then it may be straight 93 gas. If its 91 octane its blended with either 87 or 85 gas.
Even your 87 isn't straight, its usually blended with 86. Hell sometimes they don't even have 87 octane, just 86 blended with ethynol.
On the mid grade 89 octane stuff... that is blended at the pump where you get your gas. its a blend of prem and regular.
next?
