I purchased a bottle of marvel mystery oil and poured 8 ounces into the gas tank. I'm beginning to wonder if the detergent separated from the fuel since this happened after a fill up. We are going through an end of summer heatwave right now. I'm not sure if that has something to do with the problem.

I have always purchased fuel from the super convenience store near to my house, since they have the lowest prices. I did read recently that their fuel is not considered to be top tier. I've decided to go to a different gas station; I will keep everyone posted to see what happens. I will say that since I added marvel mystery oil to the tank and used up the fuel from the convenience store, the symptoms have not returned. I also realize that at 125k miles, this fuel pump will fail sooner or later. Has anyone had an experience where the fuel pump lasts beyond 125k miles?

I did indeed change the filter about a year ago. It's been a few weeks now and I've bought fuel at BP instead of the local convenience store. The noise has not returned. I will be taking a long trip today so I will see what happens.
