When I had my 1LE at the dealer for its second free oil change, I noticed the tech that was performing the work had a particular funnel that screwed in place where the fill cap goes. I believe it had a bit of an angle to it to. He was able to screw the funnel in in place of the oil cap, start pouring in a bottle of M1 0w-40, and let the bottle sit in the funnel to finish draining. No mess, no fuss, and it worked like a charm. I didn't get the chance to ask him where he got the funnel. He appeared to be the only one using it at the time.

Does anyone know about this style of funnel or where I could pick one up? The ones I see online (like at Amazon) usually state that they dont fit the 5.3 Ecotec V8's (L83), which I would assume have the same oil fill caps & threads as the L86's and LT1's. If one that works for our LT1's would also work for the 2.5L N/A Ecotec or the 1.4L Turbo Ecotec (Trax), that would be a bonus too. Any ideas?
