I would also drain the water seperator. It is located on the drivers side under the bed in front of the rear wheel. You will see a little knob to turn. Drain about 6-8 ounces into a clear jar/bottle and you can see if you have any water.

I would also have the dealer run an Oasis report and he can tell you when the last time it had the fuel filters changed and if it is time for that.
I have filters coming, didn't want to worry about when they were changed last.
