...gas gauge light went on this morning.
I'm in a bit of a quandry. I need to take the car in for an oil change and the 10k mile service. I don't want a CEL going off before I go in, so I probably won't be increasing the amount of E85 in the tank on this next fillup. If anything, I should probably back off a bit.
Also, my appointment at the dealer isn't until the 18th. I might have ANOTHER tank by then. That would be two "wasted" tanks!
