Justin, try to think "outside the box". Just because they don't use Banshee in the article doesn't mean it cannot apply. The recommended drain interval for a car is 3k miles, no one rides even that many miles before they change thier case oil on the banshee. Try to think in relationship terms. If you normally change your regular oil every 10 hours of ride time, you could theoretically go 30 hours with a synthetic. Try to apply it in your specific situation and skip the literals. No they don't freakin mean run your banshee 15000 miles and then change your oil.
Does it apply for 2 strokes? It absolutely does for me!!
