    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Yes. It makes life easier in two ways: 1. It prevents me from having to use a socket wrench to drain the oil (which eliminates me having to clean oil out of my socket, off my wrench, and off my arm). 2. If I wish, I can drain most of the oil directly into a disposable container (instead of...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    My first time to change the oil on the [new to me] Tahoe. I put these Fumoto valves on every vehicle I own. I've been using them for 10 years without any trouble whatsoever. I absolutely love them.

    I appreciate all the feedback so far -you guys have been very helpful and gave me the answer I needed. I didn't want to ask a super lengthy question, but since you're asking, here's the background: I traded out of a bone-stock Nissan Armada that had approximately the same horsepower and only...
