Spread the oats on a rimmed baking pan, and bake for 10 minutes. Transfer the oats to a large mixing bowl, and add the sugar, wheat germ, coconut, seeds, and nuts or raisins. Stir to mix well, then add the oil, syrup,and vanilla extract. Mix until everything is moistened.
Spread half of the mixture on each of 2 rimmed baking sheets (or bake in 2 batches), and bake for 10 minutes. Stir after 5 minutes to brown evenly.
