Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city. 

 

Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.  

 

@txab, any thoughts on that?

Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

Around 2008 if memory serves they took sulfur out. That was when diesel went up.

Swap costs and supply/demand balance. When a barrel comes out of the ground the entire range of products are present but not all at the same percentage. 

 

Breakdown of Refined Products

The following table summarizes the approximate output from a standard 42-gallon barrel of crude oil:

Product Type Gallons per Barrel Percentage of Total
Gasoline 20 gallons 45%
Diesel Fuel 9 gallons 21%
Other Products 13 gallons 31%

 

Most of that diesel figure is 'straight run' or cut from the barrel. Gasoline 'cut from the barrel runs 0 to 20% at the crude. So in the crude unit there is more diesel the gasoline, usually.  The full refining experience however gives the tabled values. Ego there is half the diesel than gasoline after the 'first crack' That could be an FCC unit, or Isomax or....

 

Those units take heavy products and break the big ones into little ones. Those numbers are harder to get hold of but directionally it ends up the same. 

 

Really light products are very profitable. Ethylene and Propylene to name two. Those are cracked from slightly heavier feeds like NG and Propane and Ethane. The cracker harshness determines the feed for distillation. Those feeds come from less profitable products like diesel and gasoline. 

 

So...there is a swap cost. How much market is there TODAY and what crude am I running TODAY..... what is my process capable of always. 

 

There is this as well. The USA uses allot more gasoline than it does diesel so in the cracker the process is tilted to gasoline production which....limits supply of diesel. OTR uses the most and it has different requirements than automotive and agricultural.  Limiting auto products. 

 

You are correct however. It is less refined, just less of it. Allot less.

It added a cost layer to an already limited production supply. True that.

I figured you would know about it.

    • Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge. 
    • There are no stickers in your glovebox?
    • Look at the numbers on the stickers in the door jam...
    • Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.
    • After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
