Save a little cash at the pump

Petro-WHAT??

Sorry m58,but Swoop is correct. Neither the cavitation or hot fuel problems have been solved.
ALL purchasers are being affected financially by both.In other words; You AINT gettin' what ya paid for. Even in Minnesota.
Yes the pumps are certified to be accurate.But,that's only at the SLOWEST rate of fill and then ONLY at a fuel temp of 60°.
Only thing is,fuel is NEVER pumped at that rate and temperature.
OOIDA has been working diligently in an attempt to have both problems rectified.
Keep in mind that it's VERY hard to persuade oil companies to stop taking extra profits on every gallon of gas/diesel sold.

I may not be a Petrochemical Engineer,but I AM an OTR Driver and I DID stay at a Holiday Inn Express last night.

When I pumped gas recently I noticed a sign on the pump that said this pump is regulated to provide 231 cubic inches or something like that. What does that mean to this discussion?

My field of study was more along the lines of distillation and refining of petroleum and chemical products, so I am not what you would consider an expert in retail distribution (never worked for dept. of weights and measure which is responsible for regulations on pumps).  That being said, I believe what you are referring to is the "tested" flow rate of the pump.  I'm not sure if that is done by actual volume comparison or mathmatically which are vastly different.  I believe this rating is mostly to show compliance with the ORVR ( onboard refuelling vapor recovery) systems, which are supposed to reduce pollution during refuelling.  Yes, the flow rate definitely has an effect on the presence or lack of cavitation in a system, but there are many other factors at play, also. Although educated for, it has been a long time since I worked in this field, so don't take my word as absolute gospel.  I do have my bouts with C.R.S. syndrome.   I am, however, willing to share what knowledge I have or don my ignorance for all to see.  Probably the latter.

When I was in my teens my Dad drove a tanker delivering to gas stations around NH and Ma. When I heard people say "I never buy that crappy brand "A" gas I only use brand "B" I would laugh, having seen both brands being loaded from the same pump. But brand "B" was 2 or 3 cents more per gallon

Having never owned a car( I don't have a license to drive one), but riding bikes most of my adult life, I can't comment on how various brands of gas would affect cars, but I have noticed differences in how various brands of gas would do in my bikes.

For the record: my bikes included a Yamaha XJ600F, Yamaha SRX 6, Honda XBR500/GB500TT, Honda CB750KZ, Honda CBX-1000, BMW R100RS (never should have sold that one ) and a Italjet Formula 125 scooter.

Most brands would bring similar results in MPG, but using for example Shell gas in my CBX, Yamaha's and BMW would result in a higher fuel consumption, where as Mobil gas would do the opposite. I realise that this is not a scientific study, but I think it might be smart just to experiment with various brands and keeping record of various fuel consumption figures.

I think Rastus and Swoop will confirm that all gasoline is refined the same way (at least in the US) I know that Mobiles additive is a small test tube dumped into 8000 gallons.

Yep.  The only difference, in my experience, between the different brands of gasoline is the additives they have mixed in.  At least all brands which share a common refinery. They are all distilled and refined in the same manner. In my area, the only gasoline that is not from the exact same crude stock, is Shell.  It is shipped from Cincinnati.  Exxon is also shipped here from WV, but only because they send it there, from here, by barge, to mix in their additives.  (Pretty cost effective, huh?  )

231 cubic inches is equal to one US gallon.
