I'm with RJ. I use an eye dropper for the Mobil 1. I'll admit, it's kind of pathetic when you are filling up the dropper, and you begin to fathom just how long that quart will last you.
I've gotten a bit more creative with the Superlube. Mine came in the squeeze tube, which doesn't always go where you want it. After I squeeze it along the rails and such, I brush it out more precisely with a small paint brush. I got one of those 10-packs of really small kids paint brushes for around a dollar or so at the corner drug store.
I know this sounds like a lot of effort, but it really doesn't bother me. I figure if I spend the extra time to get it right, maybe even a little obsessively so, at least I know the job has been done correctly and I can count on my R9 when I need it.
