I, for one, will never get close to those guys again. I went drinking with them one night before a "northern viking" thing.. they're nuts. But girls sure like them
I can find word of mouth info above and beyond what is available on the catapillar site.. but that's about it. I wasn't aware that Delco made them, but then again, I didn't know yesterday that the clocks on my wall were made by blind people. It's not who makes it, but how it's made.. I guess. I am aware of how durable they are in thier own application, and the abuse they put up with, somewhat first hand. I'll see what's out there.
Remember though, on advice from me: I'm the guy who runs 15w40 in his jeep and swears by it, so YMMV.
