I've never had a problem with the caps except when overfilled? Just have to remember white half down.
You'll like the 260. It's "right-sized" for my small farm. Small enough for easy handling but big enough for the tough jobs. Watch them there flip caps. They'll trick you into thinking they are locked. I poured a half tank of bar oil down my pants leg and on my boot. Bar oil stays a while on pants and boots.
