    Short answer: 5w30. 2015-2020 s550s specifically have had '5w20' written on their oil cap but their manual also specifies to run 5w30 on the track From 2021+, they decided to replace 5w20 recommendation all-together and their oil cap now reads... (see full post)

    Other than the door sticker and dashboard at the base of windshield are there other locations with VIN numbers? I am looking for a salvage car and/or parts, and these locations aren't always available.

    I agree! I had an issue with wiring and they were very helpful in figuring it out.Now it's not that I'm having issues with the module, but more so that its difficult for me to get used to. When I downshift, I naturally rotate my heel to blip... (see full post)

    Your car should be standalone, except for traction control. But I think the brake portion should work fine without the factory ECU. just needs power and wheel speeds. (see full post)

    I do have an extra trans temp gauge in the dash that I'm not using....it could happen. lol. Seriously, I am probably over cooling the oil....5/50 is good thin oil but that's probably cooler than it should be. I can tell you this, and you've seen... (see full post)

    That’s basically where I settled as well Tracy. Under warranty…use what the book calls for.I’ll give you Holly’s number. I’ve already tried…🤬🤬🤬. Work on the Barber event in February while you’re at it. (see full post)

    TMSBOSS replied to the thread 5W-20 or 5W-30.
    PatrickI looked at the manual also. Ford says 5W-30 and the car should still be under warranty. Not a hard decision there. Why do other sites list 5W-20? I could guess. Or better yet assume others are guessing. Why deviate away from the... (see full post)

    Oh for sure, I know the advantages. I'm running a 35 psi pressure relief system on my car. It's all un tested still, but it should work well.Maybe we can convince him to add another gauge there.. For research purposes (see full post)
