You shouldn't have any trouble finding either type of oil in Central and South America. Motorcycles are the cheapest form of transportation, so they're highly popular in poorer countries, i.e. Latin America. Which also means that there's lots of motorcycle engine oil available. I never had any problem finding synthetic oil for my KLR anywhere from Mexico to Argentina.
On a side note, I've always used a reusable stainless steel oil filter on my KLR. Highly superior to a paper filter for various reasons, it also has the added advantage of never having to look for an oil filter agian. Athough finding oil isn't a problem, finding the right filter can be. Dual-Star sells them for $65, but it's well worth the investment.

While you're there, I also can't recommend too highly the sub-frame upgrade kit and the monster tubes. Please do yourself a huge favor and at least order these last two products. I personally wouldn't leave home without them, especially if I were travelling south of the border.
