The TSC bar oil thread got me thinking, and I didn't want to hijack it. So for those of you who have used a bunch of different cheapo bar oils (by that I mean oils marked specifically as chainsaw bar oils, not other oils like straight 30 weight), are there any that you felt weren't good enough for your saws? I ask because sometimes a fella runs across those screaming clearance sales on no-name bar lube and doesn't have time to check in here on AS. I've cut with the Poulan and TSC lubes and thought they did fine, but I know there are a bunch of other cheap lubes. Thoughts on any that I really shouldn't run in my saws? Thanks!
