I like having a direct answer to my question "how much oil does my engine take" but as of today I do not trust the answer to be correct, so I still cross check several sources, ideally ones that appear to be authoritative.

I asked claude to dig up the current Ford Bulletin for the engine in my truck to tell me the recommended motor oil. And it found the updated recommendations properly. I wouldn't trust google AI because I know specifically that the recommendations changed, and I don't want whatever the published specs were when the engine was first manufactured, which is out of date (and found on lots of low quality blogs). I don't even trust claude, but it gave me the URL to click on to verify and summarized it well enough that I mostly trusted that it wasn't using the cited technical bulletin and not a bunch of random AI-slop web pages.

I wouldn't trust any 'confident stochastic next-word predictor' to tell me fact. There are official sources of information for these kinds of car maintenance questions.

		Better than asking your backyard mechanic buddy who believes that you don't need anything other than 10W40 or something like that. You have always had to know who to trust and what level of work you need to do in order to get to an answer which is satisfactory. And in this case, Claude cited the manufacturer's bulletin which is the actual best source of truth that you're talking about.
