It makes me a bit nervous putting in "premium" fuel every time I do it .......because the turn over in that tank at the station has to be a lot less.
Going to a high volume station where "sports cars" are in evidence should reduce the chance of getting "bad gas".
Actually, (at least in this country, & I reeaallly can't see yours being
that much different! We tend to share many of the same or similar practices in things like this...) apart from the 'less used' bulk tank having the possibility of delivering a little slightly older fuel (but usually not anywhere near 'old enough' to have degraded any or be 'stale', because that takes months
or more to occur, & gas stations selling that small a quantity of gas are generally required to take other steps to turn over their inventory) the fuel from a less used tank is likely to be LESS contaminated than that from a frequently topped up & continually disturbed tank, except in the rare instance that you might get the very dregs from the lowest levels of fuel remaining in the bottom of a nearly empty tank!! But then, that is another thing more likely to happen far more often in at a high turnover gas station rather than a low turnover station, where they tend to be very aware of how much (or little) premium gas they've sold!! nojoke
The less used tank has little movement to continually stir & lift/mix in all of the contaminants that end up settling into the bottom of bulk gas tanks, while the frequently used tank, which has its pick-up pipe inlet down fairly low in the bottom third of the tank anyway, is going to be ALWAYS getting its contents stirred & mixed up - cos
every time ANY gas gets pumped out of that tank, it creates eddies & currents in the contents & thereby mixes into the good stuff some of the contaminants that invariably end up trying to settle into the depths of those bulk tanks, so that the buyer ends up with a somewhat greater chance of getting crap fuel pumped into their vehicle
from the MORE FREQUENTLY USED tank than they do from the bulk tank that only gets a small amount pumped out every now & then!! The gas in the less used tank settles all the crappy stuff down into the very bottom of the tank, where there is a 'depression' or deeper curve carefully designed into the shape of the tank base especially to collect & contain all that crappy stuff, & when someone does buy gas from that tank the pick up lifts that gas from above that contamination level; ie from the well stettled, even temperature of the low/mid level depths (but well clear of the crappy fuel collection level) without any of the regular eddies & currents always mixing in the rubbish stuff like they do in the often used tank! :shocked:
You want to see this for yourself?? Well you can see this happen for yourself fairly easily, just get a largish glass jar (1 litre or so capacity should work) with a tight fitting & sealing lid, then fill it almost full of gas (or better yet, use diesel - it's easier to see the distinct layers as things settle) & add saaay, a half a cup full of water with some light dirt or mud or something similar mixed into it, then put the lid on the jar tight & shake it reasonably vigourously, which is pretty much what happens when a nearly empty bulk gas tank gets filled - everything gets dumped in & mixed up fairly vigourously. Then set that jar carefully on its side on the table so that it cant roll or move any & leave it there to settle for a while, noting that it might take 6 or more hours for the mixed in contaminants to settle out fully. But eventually, you'll see the contaminants settle into the bottom arc of the jar, much like the fuel in the less often used bulk tank will - aren't you glad you didn't fill your Spyders tank from THAT bulk tank until all the fuel had settled?!? Or did you?? How often does that high usage gas station get premium gas bulk deliveries?? Once a day, or once a week?? When was it last done?? :sour:
Anyhow, once it's all settled & you can see the layer of dirty water/contaminants settled in the bottom of the tank, now imagine your fuel being sucked out from about 1/3rd the way up from the bottom/side of the jar resting on the table - well clear of the contaminants settled down low in the less used tank; that's gotta be pretty good fuel, doesn't it?? And if it's less than about 6 months old, it's going to be perfectly fine, cos it's kept at a relatively stable temp & largely blocked away from moving air (altho it is vented thru a snazy vent system that limits moving air & therefore loss of all the important aromatics & esters & other stuff etc that make it stay 'fresh'! But in the case of the regularly used bulk tank, the one refilled at least weekly if not more often, to replicate
THAT, you'd need to pick up the jar & gently shake it once or twice every few minutes or hours, maybe even use a straw to suck out a few mls of gas from the 1 litre jar every couple of minutes or so, remembering to suck it out from about 1/3rd deep down in the tank, but not from the dodgy stuff right in the bottom!! It doesn't need much removed or much of a shake to replicate regular usage, but if it happens just often enough to make the 'settled out contaminants' move a little & mix in with the clean fuel due to the eddies & currents that DO get created EVERY SINGLE TIME some gas is pumped out into a vehicle!! Check out how the contaminants mix into the good stuff - it doesn't take much gas going or it happening too often, but the more often the jar (or the tank) is agitated (or has some gas sucked out) the more active those eddies & currents will be & the more mixed in the crap that should settle out in the bottom of the less used jar (or tank) becomes in the frequently used tank! And then in addition to that, the tanks contents get REALLY mixed up every time it gets down to about half empty, bringing in more fuel to top it up and aggressively stir everything up & mix in all the crap that should've been in the bottom that might've just started to settle out!! :yikes:
Now tell me again
WHICH bulk gas tank you want the fuel going into YOUR Spyder to be pumped from?? :shocked:
