This is for our 2008 Mazda CX-9 Grand Touring. I changed out the oil a little early because we are busy during the holidays and I wanted to get started on Pennzoil's "Make the Switch" program. This UOA is for PUP 5w20 paired with a RP 20-400 filter. The PUP ran great, no complaints. The previous two UOA's were with RP HPS 5w20. It looks like the lead is still sticking around. Our driving is the same as previously, lots of short trips and stop and go in a hilly area. The only thing that has changed since we started seeing Lead was that I installed a Dimple magnetic drain plug before that OCI, but I don't think that it would change anything. Should we be concerned?
In Australia the same car/engine is spec'd for 5w30 and higher. If the next run on PUP 5w20 still shows lead would it be safe to run PUP 5w30 to see if that helps? Or am I over thinking it?
Thanks in advance!
