Up until 60k I had free oil changes, the dealer did it. Once that was up I’m doing it myself. I looked at the filler cap and it says 5W-20. So that’s what I put in. Somewhere along the line I found out the manual says 5W-30 ! In a search of the internet it said that it was common for Lincoln to have the wrong/misprinted weight on the filler cap ! Now I did do two oil changes already with 5W-20 4k in between each. I know two oil changes with 4k in between won’t kill the engine but long term if I didn’t find this out it could cause excessive wear internally. But I wanted to post this in case anyone else runs across the same thing. Why wasn’t there a recall for this ?
