The early 5.7 (345) in my 2006 Charger Daytona has about 245,000 mile on it. I seem to get the least valve noise, the least blow-by and no smoke when using Castrol GTX 0W20. It keeps my MDS working smoothly as well. In the 2003 Dodge Ram Quadcab with 4.7 V8 with about 250,000 miles, I usually run 0-30 and a bottle of Lucas Oil Stabilizer. This reduces the valve noise during cold startup and the Lucas helps keep it quiet by increasing oil surface tension. Both of these engine designs are known for valve train lubrication issues, but I'm doing okay. I've owned the Daytona for almost 5 years and the Ram Quadcab since I bought it new in November 2002. For the newer Hemi engines we've owned, we run whatever the dealership service department puts in them.

So, after reading lot about LubeGard and ticking, I'm thinking it might be a good idea to run it with PuP 0W-40 in my new 6.4. It doesn't seem to tick right now and I'd like to keep it that way.

My question, though, is how long to wait before adding it on oil changes? I did the break-in oil change at about 1K miles and used PuP 0W-40. I'm currently approaching 3K miles and was going to do another oil change at 4K. Is it better to add the LubeGard now or wait a bit longer for better engine break-in?
