Twice now, I have pulled into the GetGo gas station where I fill up only to see the tanker truck filling the station's tank. Both times, I have turned around and left without gas, for fear of filling my tank with sediment stirred up when the tanker adds gas to the station reservoir. The problem is that it is not always convenient to get to this station, and I do often save $10-20 per fillup there since we don't drive much and do a lot of grocery shopping (GetGo gives $0.20 discount per $50 spent at GiantEagle, and it is cumulative. Extreme example: I filled up paying $0.19/gal the other day ).
Many have said in the recent gas threads that you want a station that has a lot of traffic and therefore fresh fuel. Great, but what about the sediment stirred up when they fill the tanks? Is that a concern? If so, how long after they fill the reservoir would you wait before pumping gas there?
I do not want to start yet another discussion about cheap gas vs good gas - I want to know whether there is a danger in filling up while the tanker is refilling the station, and if so, how long to wait.
