Ethanol gasoline is hydrascopic, and as such, absorbs water especially if you let it set for more than 3 months. Using a product like startron is usually a waste of money, unless your bike sets, and then its' effect is questionable. Most additives are not cost effective, and in most instances, even if you think they work, what scientific basis do you have to make sure.[snip]
