Good luck! As far as oil goes the cheap stuff from walmart works fine! From an environmental stand point a full synthetic is best, I think. I am currently using Petron Plus which is mineral based and a little pricey. No matter what oil you are using buy a bottle of oil that lets you squeze out oil into a graduated section in the top that lets you measure as you dispense. These things are totally handy and easily refillable. I also recomend mixing one gallon of gas at a time this will last a long time!
