I thought synthetic was superior at extended change intervals.


They are, but..... These little motors do not have oil filters. The only way the dirt in the oil can get out is with an oil change. Whether dino or synthetic, it makes no difference. Dirt is dirt.
Not sure on the Yamahas, but my EU2000s only take 12 oz on a change. So I do it VERY often.
I use dino oil as it won't be worn out/broke down... Just dirty.
