    All I know is only 1 bottle, the tick went away, a smidge in mileage, and it's as quite as a mouse until I put my foot down.

    Liqui-Moly says you can use it every oil change if you want, but not really needed.

    I did a test run on my 2.2 ecotec Malibu and it seemed to improve gas mileage a bit and quieted down the 140k valvetrain. I might put it in the mustang next time I change the oil.

    Ford does use specially formulated additive packs in their factory fill oil. They can’t use this in the oil they sell at the dealership, as it likely exceeds the limits on certain compounds.

    I've read so many differing opinions on oil that it would make your head swim. I found this article pretty informative.

    https://www.carbibles.com/guide-to-engine-oil/

    I personally use Mobile 5W30, every 6 months which is around 7500 miles between changes.

    My '18 manual says 5w/30 for track days for the 5.0 (page 246).

    I've heard of this secret sauce - I think it's probably a good reason to keep the factory fill in until due for a change.

    THis to me sounds like a myth, probably also perpetuated on youtube (lots of myths are there). I cannot find a single thing confirming it from Ford. So I call BS on it. Sorry.

    you should read your owners manual more clearly, there are actually a few oil weight recommendations based upon usage.

    5w20 is usually recommended only to make CAFE mileage standards. 5w30 is also perfectly acceptable, and offers better protection. 5w50 if you're doing heavy track usage.

    Also, the engineers at Ford did not formulate the factory oil fill for your car. Ford Motorcraft is blended by Conoco Phillips, and is purchased because it is the cheapest bidder.

    I think there must be some confusion here between the 5.0 and the 2.3. I've read my owner's manual from cover to cover. For the 5.0, it recommends 5w/20. For track use, switch to 5w/30, but switch back to 5w/20 afterwards (p. 246). You can also use 0w/20 for extremely cold climates (p. 304). I see no mention anywhere else for anything different.

    interesting, used to stick 5w50 in track pack models. Anyway, I'd not hesitate to use 5w30 all day everyday in a 5.0, or even 5w50.

    Please provide the data (from Ford engineering) that supports your statement that 5W-20 is only to meet CAFE standards.

    The manufacturer of diesel engines and construction equipment where I worked for many years also did not make their own: oil; filters; batteries; and many other items *but they did provide their own specifications to the suppliers who made them*. Motorcraft oil may be made by numerous suppliers but it is to Ford specifications.

    The industry trend to lower viscosity oil is driven by cafe fuel economy requirements.

    This is true. The move to synthetic (or synthetic blend) factory fills in many makes has enabled sufficient protection in difficult OEM durability cycles at lower oil weights. Over the years you've seen companies like Honda change their weights within vehicle generations and no changes otherwise to the engine.

    This is true, and ford even went as far as back-spec’ing older engines originally designed for 5w30 down to 5w20....even stating it was for fuel economy reasons.

    It's not a myth. My previous company developed the additives for engine oil, and we formulated factory fill packages for a few OEMs. They contain high levels of dispersants at a minimum, which isn't generally seen in oil you buy off the shelf. I can't speak to Ford's specific factory fill package, but it would be unusual if they didn't do the same as many other OEMs.
