Changed out my OCI 2 weeks ago with 5w30 Traveller Full Syn & using a Fram Extra Guard filter. I understand that WP oil products package this brand for TSC. I added 1 quart of 10w30 to make it a little thicker.
Now my 4.7 v-8 (2005 Jeep with 90k original miles) is making 'sloshing' sound like a noisy valve train/chain or possible piston slap?
I've never had this issues with Pennzoil or Havoline HM oil that I've used in the past.
Should I be concerned? Or just dump this 5w30 Traveller and start again? Temps here in summer are from 75 to 105.
