Good morning Lil ME, PC, Purelife, kitten, and Lise.
I second PC's pizza dough idea, and using a bread maker. I cant help you with what pizza crust to buy lil me, I can tell you we buy the big frozen pizzas from stupidstore though and then add more of our own meat and cheese on top of it.
Miss Lise, as Schade said, for what it sounds like take it to the dealer. There should be NO water in the oil whatsoever, never ever.. if theres water or dirt in the gastank (another thing I doubt) it has different symptoms from what you described.
