Oil Change Intervals

[MnemonicGhost]

I just passed 3k and have like 70% of "oil life" on the display. Even with Extreme duty and heat, I believe the manual says it should be 7,000-8,000 miles until it gets to zero. But oil is cheap insurance for a healthy engine. So I'm likely to do it on my own as well pretty soon. I think ford recommends 5w20 motorcraft semi synthetic.

Let Ford do it. They will use a Motorcraft filter and use oil that they approve of themselves. That way there's never a question of maintenance. I changed oil at 1k miles, then 5k miles, then every 5-6k miles after that. On both engines, lmao.

I switching to amsoil and changing it every 3k miles.
