I have rotella 15w40 with a quart of Lucas currently in my 4.0l.
as the weather is getting into the 30s I noticed the last couple of days when I started the jeep I would get a screeching sound 2-3 seconds after the engine started. I need to have someone start the engine while I open the hood to see if I can tell where it is coming from. I guessing its maybe the belt... But could the oil be to thick and something in the engine is rubbing metal on metal do the delay in getting the oil running. After the first start in the morning I do not heard the noise again for the rest of the day.. Should I drop to a 5w40 for the winter? With / without lucas?
