Oil change was due for the 4.SLOW so as routine I cut open my filters. Past oil change: 5w30 M1 HM on 5k oci. I decided to run M1 HM because it was the only oil I tried that completely silenced my lifter tick. I've used it before but previous oil change was Pennzoil High Mileage and my jeep just ticks like a banshee on cold starts with it. So I only ran the 5w30 for 5k miles over winter with the TG8A. This oil change: 10w40 M1 HM and another TG8A filter. Plan on going for a 6.5k oci this time. I think the oil is up to the task. I drove it around today and I forgot how much my 4.0 seems to love 10w40. Smooooooooooth and uber quiet at idle. Filter looked great as usual... Always seems like the seem pleats are spread apart farther. Oh well. Oh, and some yummy stuff. Have a great Friday and a happy weekend everyone.
